CX-Racing Test

[nickkaplz]

OK guys i drive a 1992 240sx le. this is my first thread, and post for that matter, on zilvia. My car has been running a cxracing test pipe, catback, and radiator set up for about 6 months now without a hitch. B/c of this i have decided to run thier turbo kit and see how long my car survives without a tune like they say it should. here is a link to the kit cxracing.com: Newly Released Complete Turbo Kit for 91-94 Nissan S13 240SX with Stock KA24DE DOHC Dual Cam Engine (http://www.cxracing.com/mm5/merchant.mvc?Screen=PROD&Store_Code=CXR&Product_Code=TRB-KIT-S13-KA24DE-IC-KIT&Category_Code=TOKT)
What i plan on doing is reviewing the arrival (packaging, quality), install, and over all quality of the kit once it is running. I know its not the best quality but thats why i bought it. i have more engines so if i blow one i blow one. I have no connections to cx racing so my opinion will be strickly based off the quality off the kit. please leave any feed back if it may help.

[rob22]

i was actually thinking about purchasing one of there kits
but ended up piecing together my own.
when are you getting the kit?

[nickkaplz]

its being shipped as we speak

[rob22]

thats cool.
how much did you pay?
whats all included?

[nickkaplz]

it was 1300 shipped and the parts are listed in the link from the original post

[Edwin562]

im looking forward on seeing your outcome.. i will subscribe

[rob22]

thats not to bad.
keep us updated!

Heh, I hear detenation on many ka's with 87, they really should run on premium as is. Throwing boost on top of that is not that great of an idea. Then your going to throw on a bigger turbo than a t25 and run it with 275cc injectors with no ecu tune.

Its kinda hard to screw up a catback and test pipe, even if it might sound bad what problem would you expect to have with it? Its not going to rust and its not going to self destruct. But your luck with their exhaust is prompting you to trust them with their turbo kit?

CXRacing is the only one offers a production Turbo kit for this car and engine.

False and they cant even grammar check their website description?

Most of the 240SX are swapped with Japanese SR20 or RB Engines, but with these engines getting harder to find and increased costs

false and false. I believe most 240sx's still have ka's in them, and they are getting harder to find and more expensive since when? When I got my first 240sx 9 years ago it was like seeing a ghost anytime you actually seen a sr or rb. They were so expensive it wasnt funny. Almost not even worth getting. I remember a local tuning shop had a rb26dett sitting in their showroom with a $10k price tag hanging on it about 10 years ago.

but no major vendor has produced such a kit. CXRacing is the 1st vendor to offer a complete kit.

once again, no

And take a look at the install picture on their site. They are not only incapable of understanding proper crank case ventilation, look how short the turbo inlet is... the maf is way too close to the turbo. And then what is this? A black plastic maf? So thats not a stock maf which means they must have tuned their own ecu.


You would be much better off starting with something like this as a base *ISIS Turbo Upgrade Package - Nissan KA24DE 91-98 [ IS-TurboKitKAT ] - Enjuku Racing - Performance Parts and High Quality Fabrication (http://www.enjukuracing.com/isis-turbo-upgrade-package-nissan-ka24de-9198-p-10228.html) and getting your turbo lines as they dont come with it and taking their word on the fact that you will need a tune.

Take it for what its worth, but I can confidently say I have seen my fair share of built 240s and tuned several as well.

[bookoo]

^^^^^ Brandon speaks the truth...seen it personally...

[roboticnissan]

I bought their sohc turbo kit. Everything bolted up really well, the motor lasted an hour Haha. My sohc had over 200k miles tho.

[4x4le]

^^^^^ Brandon speaks the truth...seen it personally...

ah, nismo junky, had to look at threads you created to see how I knew you and came across your s13 fs thread.

lol, yea them "no name" coilovers on the s14 are actually really nice arnt they? I wouldnt put my rep on them if I didnt think they were good.

[lazysk8er2]

i dont care what anyone says, u need to tune the ecu

[Biggamehit]

I dont know about the full kits but I have been running a CX racing manifold on my Holset RB setup for roughly 2 years now. biggest issue I had with it was the tube design, it is not accurate at all. Two studs cant be utilized right under the turbo mounting junction and one is a super tight fit.

It has never cracked on me though but getting rid of it soon.

I also ran a CX racing Intake manifold. Pretty bad Casting job had to patch it with jb weld to stop leaks. Now I run a ISIS intake manifold.

good luck.

[nickkaplz]

I completely agree that the ecu needs a tune and i dont plan on going super hard on the engine until it does. All the things posted about the kits web page are true and im not fighting that. this is just a test to see what happens and honestly i dont expect good results, i am just willing to try and see what happens. after the initial install i will run the car for about a month before adding injectors, fuel pump, tune, z32maf, spec stage 3 clucth, flywheel, and many other pieces to max the kit out before blowing the stock internals all over the side of the road.This is simply a quality test, not me trying to tell some one to run this kit instead of another brand. Trust me i know what im getting into with this

[Biggamehit]

As stated the tune is everything...

My first KA-T setup cost me 800 dollars and was solid because I stayed below the recommended boost levels. I added a wideband, safcII, S15 injectors and backed the timing off. I drove it daily along with lots of drifting, auto-x and some drag.

Keep the boost reasonably low and you will be fine. Whats the compression of your engine currently across all 4?

[nickkaplz]

i havent had the compression checked, the engine just hit 100000 and runs like a top. i think will be getting a rs enthapy tune. what companies do you advise for this set up? and it will see 7pounds boost at max.

.

This is arriving at my doorstep today.

Ken was kick ass to deal with when ordering. I cannot wait to get it installed and get the car running.

[nickkaplz]

i considered that kit for a while, but it seemed to be missing too many things for the price when compared to the cxracing kit even though that is still a great product

[waxball88]

I'm running the cxr kit. Bought it 2 years ago and everything worked well til my engine blew. Now i'm built but with the same kit. From manifold to i/c to exhaust.
http://i166.photobucket.com/albums/u116/waxball88/100_0921.jpg

How your manifold/dp fit to the Master cyl depends on who was welding that day. I lucked out and have enough room for a heat shield. I wrapped my downpipe anyway too.
Things i'd recommend
Throw the gauges they give you away
BOV is ok, but idk how long it'll last.
Cut and modify their i/c pipe on the hotside other wise you get a cluster fuck when running a filter.
Wrap downpipe
Heatshield
DO SOMETHING WITH YOUR PCV
GET A GOOD TUNE

Things i'm running not included with kit.
Enthalpy tune
sti 550s
Wideband
z32 maf

[nickkaplz]

How long did you run your kit without adding anything new?

[Biggamehit]

Look at the kit like buying beef.... in raw form really not that tasty. You gotta add some species to make it better. Essentially you will have to pull certain parts from the kit and or add others. I am for building your own kits as you learn much more if you are lacking the knowledge. With the amount of part outs on this forum and others, you could assemble a kit for about the same or less _+ $400-600 dollars maybe.

[nickkaplz]

I would like to build my own kit one day but as of I now I have no turbo experince so this wil be a good Learning experience and base for me to add to. BTW I am looking for used sr injectors or something similiar if anyone has some for sale

[ca18_luv]

It really depends. I ran kit for a long time about a year. However i tore apart my entire ka and freshed it up. Just a stock rebuild. I had the top mount kit (not sure if you got top mount or bottom mount). Too lazy to type a paragraph so imma make it quick and if you have any questions feel free to ask :)

Pros
-Kit fit all really well
-Customer service great
-Packaged well
-Ran great
-Drove the car all the way from Santa Clarita to Salt Lake City, Utah for business on 12lbs with no issues
-I DD the the car at 12lbs everyday and it was sex

Personal cons
-Exhaust mani started to crack and causing leaks(had to weld supports)
-Greddy "STYLE" BOV was giving me pms issues
-Diagram on wastegate blew causing me to over boost and eff up piston #2


Things i would recommend
-Do it right and take time while putting together
-Do a stock rebuild on your ka
-Dont reuse your head bolts as they stretch, get head studs
-Dont go over 12lbs
-As stated by someone else do something with your PCV (i blocked mine off and removed butterflies from intake manifold)

A couple other things i did
-370cc injectors
-Braided lines for oil feed and return
-Head studs
-Felpro gasket
-Bigger radiator
-Got a chip i had to solder into my ecu for the tune (forget name but it made a huge difference)
-255 walboro fuel pump
-Boost, Water Temp, Oil Pressure gauges


If i remember more i will add lol




All in all i was please with it for being my first boost project and something to learn from.I loved my KA-T.

[feito]

definitely following this thread

[ca18_luv]

ill post a pic of my setup once i get home, dumb work computer wont allow me to go to photobucket -_-

[dj6923]

Good luck with the kit. I believe I've seen you on hwy 65 or 459 once or twice. I drive a purpleish rbs14. When I saw this car I didn't have a front bumper so all you saw was the I/C. Anyway it seems like you have a plan and its moving along fairly well. I also have a few Cxracing parts on my car and haven't had any complaints yet.

[thrax]

I'm sure lots of people will follow this thread as this kit is often asked about.

[nickkaplz]

this is the bottom mount kit and hopefully i will be able to answer all questions about because that the reason why i made it. a lot of people seem to want this kit its just not documented very well.

[nickkaplz]

I do now have a set of Sr injectors and a n60 maf headed my way and the turbo kit should be here on Thursday

[nickkaplz]

i feel really stupid for having to ask this, but will an ecu tuned for a t28 work with this kit?i ordered one off the rs enthapy site with a tune for my injectors, and maf, but i didnt even think about turbo size ..... i know im stupid but it was a great price. if it helps this kit will not go above 7 pounds

[4x4le]

It will work better than running on a stock ecu. Not saying it wont be problamatic though. We have an entire box full of peoples jwt, enthaply, mines, emance ect. boards and there is a story behind each one.
Idle always sucked, or mpg was bad, or blew up motors or detenation was audiable, or there was a lean spot that was always there ect.

Things like this can be expected from mail in tunes. The best way to tune an ecu is on the dyno with someone qualified doing the tuning.

sent from my rooted thunderbolt

[lazysk8er2]

dont do it! even though a tune is necessary

run the kit the way the company recommends on the website to show how it works.

[nickkaplz]

i do plan on running the kit a couple of weeks with no tune, but im pretty scared :duh:, and also i would prefer a real dyno tune, buit the closest person to me is over two hours away in atlanta! this is why building in alabama sucks

[4x4le]

It takes longer to change an engine out than it takes to drive to atlanta. Hell im probably closer to you than atlanta.

[nickkaplz]

If you tune ecu's send me a pm with pricing please

[MYN1SMO]

Trust me i know what im getting into with this

i do plan on running the kit a couple of weeks with no tune, but im pretty scared

lol starting to get doubts :duh:

[lazysk8er2]

honestly ive never had a problem with rs enthalpy...all my experiences with them has been nothing but positive, even helping me diagnose my car over the phone to track down a wiring problem.

If you dont like the tune you can send back the chips on the daughterboard if anything is wrong. I also like the new function where you can switch across 2 separate maps.

another option you can use is nistune so you can build the maps yourself onto the stock computer

[nickkaplz]

Thanks for the info guys! If my engine survives ill put the rs enthalpy tune on lol

[Biggamehit]

Turboing the engine is not going to blow it.... driving it stupidly without a tune will.

I recommend grabbing a safc I or II to change the hotwire settings with the new maf so that it will idle and run and also pull some percentage from the injectors if they are 550cc's or under. Dont load the engine up with boost at all if you must drive it.

A compression check will let you know right away the condition of the motor before you go any further with things.

[4x4le]

safc's dont control timing, however they do usually negatively effect it. normally the timing increases with them which is the opposet effect you want. Your much better off with an enthaply tune than a safc. I have see multiple times a ka with a working o2 sensor idle and drive fine with 370cc injectors and a stock maf with no tune and go into decent air fuel ratios under boost, the problem was the timing so a full tune still had to be done.

Ill send you a pm about my tuning services but it probably isnt worth it if you already got a enthaply tune.

[Biggamehit]

Yes Sir im aware that SAFC's don't control timing however under 12-13 psi backing base timing off is fine.

I ran my KA-T two years before leaving for japan with my SafcI. Drove it daily along with drag, auto-x and drifting pretty much every weekend. It's better than running around completely unregulated.

Timing increases negatively with OBDII setups more so than OBDI setups which I ran. Im sure you knew that considering you are in the tuning buisness. Safc are useful to those with lower end setups... proven.

My Setup had zero issues other than wishing the timing was more agressive right above mid-range but like you said no timing control with the SAFC so it was a con with my setup but got the job done. I street tuned it for normal driving myself however needed a dyno to help with the HI crossover maps.

The tune is the absolute most important part of any build as far as I'm concerned! A bad tune can make the best of kits run like crap and vise versa. Your money will be best spent on a quality ecu capable of acurately mapping out engine peramiters! (power fc, AEM, blah blah blah) Also don't think you can just street tune it either. For example, I've seen plenty of guys try to "play it safe" and back the timing down only to back it so far down they end up melting exhaust valves. Me being one of those guys haha. Leave the tuning to a professional that has the proper equipment. If you do that you can do as much experimenting with different kits and parts as you like without doing any damage. Not to mention you will have a much more accurate understanding of how different kits and parts effect the cars overall performance. I speak from experience. I once thought the tune wasn't that important or I could figure it out myself. Turned out I was better at screwing up engines rather than tuning them!! Now I trailer it to the dyno and let a pro do it. Way cheaper in the long run. Plus if its tuned right you can drive the hell out the car without any worries. Thats why we make them faster, so we can drive them fast! Either way good luck with your build. I'm sure you'll have a blast learning all about the joys of forced induction!

[nickkaplz]

Ill send you a pm about my tuning services but it probably isnt worth it if you already got a enthaply tune.

i havent actually paid for the ecu yet so send me that pm please

[nickkaplz]

not even i saw this one coming, nothing on the kit fit so I had to send it back. the manifold hit the exhaust studs, the turbo hit the block, the down pipe hit the fire wall and the inter cooler wouldnt fit behind the bumper, and the the intercooler brackets didnt work. The bolts that were sent were too big and insted of l brackets it was just some stupid metal strips. this kit is total crap. the individual parts looked to be quality but the overall fitment sucked on everything.

[di-devol]

I think everyone saw that coming.

"- Very easy to install, with minimum modification"

You gave up too quickly.

[Edwin562]

WOW what a fail....

[4x4le]

well that sucks.

It kinda is the best thing to buy everything component by component, make your brackets and piping as well as downpipe. I know it sounds like allot of work but its easier than modifying something that is supposed to fit already.

When you do it right and everything fits the way you want it you will be much more satisfied.

[ca18_luv]

You gotta play with it dood lol Manifold might need little customization, the compressor section might have to be unbolted from the turbo housing and clocked a bit then bolted back to prevent hitting block, the downpipe might need to be customized as well depending on thickness (i had to heat mine up and hit it with a hammer to creat a sort of flat spot so it wouldnt hit firewall, and you might need to trim some parts of your bumper support to let the IC fit. i made custom brackets for the intercooler it was super easy to do.

ITT - n00b doesn't even know the basics of installing a turbo kit.


Clocking the turbo and trimming the bumper are standard practice when installing stuff like this.

[lazysk8er2]

point being its not plug and play, customizing the manifold and fudging the dp defeats the purpose of their claimed "Very easy to install, with minimum modification"

and its true mods need to be done like trimming the bumper and clocking the turbo need to be done but redrilling holes into the manifold and smashing the dp should not happen

even my megan manifold and dp fit on like oem no mods needed

[nickkaplz]

everything you people say to do i have allready tried, im not going to rape my car just to get a turbo to fit, if it doesnt fit it doesnt fit and thats what the point of this thread was in the first place

[ca18_luv]

+1 on not having to eff with the downpipe and manifold in that matter. Honestly if it werent for those two small things it would have been all in all a great kit. Still a good kit but those parts sucked.

[Def]

everything you people say to do i have allready tried, im not going to rape my car just to get a turbo to fit, if it doesnt fit it doesnt fit and thats what the point of this thread was in the first place

Everybody already told you that Chinese crap wouldn't fit well from the getgo.

I guess props for at least admitting it...


Although you still don't know anything about turboing a car... :s101:

[c_mancuyas8]

hey man if youre still wanting to turbo the ka dont give up. Search the for sale forums Ive seen plenty of ka-t setups on there that are very reasonable. I waited almost 6 months before I had all the pieces to mine and just like you debated the cxr kit but Im very happy with what I was able to piece together. Ive gotten 2 sr t25's from here for about $100 each or so given they wont give 300hp they still spool fast as hell and add alot to the stock ka. Everyone is right about the tune though you gotta have one if you want to be safe. 4x4le is pretty smart guy ive known him a while if you can get to him to tune your car do it!

[Walperstyle]

I really would have spent more time reading online before spending money on a turbo kit. I've been building my KA-T for a couple of years now, and I still don't have my turbo or intercooler pipes. Or a hole drilled in my oil pan for that matter for oil return. Because I'm doing it the right way.

i dont care what anyone says, u need to tune the ecu



In the event anyone missed that... Engine Management is very important when you start playing around with turbos and injectors.

[Flipp]

for those with the kit, did you have to mod or move the batt tray? i have a friend who bought the kit but he says the batt tray is kinda in the way. just trying to find him a solution, if you have any ideas do let me know. ill be searching some more after this post. any help is appreciated. thanks in advance

[Tantwoforty]

Welcome to zilvia...
This thread has been dead since 2011, But i guess bumping it is better than making a new thread.
Just cut a hole right through it, your wiper fluid might be in the way, just remove it.
You can use a hole saw or a sawzall.
then you can turn the battery sideways (sometimes/ be crafty)
relocate it to the back
or get a small battery..

[Flipp]

thanks for the info, yea i was suggesting the same thing but wanted to make sure it was the right thing to do or if maybe he had the IC piping on wrong. im deployed right now and couldnt be there to look at it myself and help out.
and its always better to bump an old thread then make a new one.., no rookie thread moves here lol. thanks again

[Mishkin_707]

Well it has been almost a year, let's get an update of the kit!

[USN_S14]

i concure on that a update would be nice
