ka24et setups

[rancid240]

Just wondering what setups people are running?

I want to go with a 3-5 psi setup...no intercooler/bov, t3 turbo, custom manifold (friends dad is a professional welder)...as basic as you can get. Other things I will need is FPR, walbro pump, downpipe, tapped oil pan, oil lines-

can someone explain to me how a manual boost controller works?? Will I need one to run 3-5 psi? Also, what is the deal with external/internal wastegates?

Suggestions? I am looking for just a little punch for the ka24...nothing too drastic. Also want to keep it under $1k (possible?:confused: )

Me and my brother have turboed a few KAs. If you have any questions that I can help you with Email me at [email protected] or PM me with yahoo messenger. My yahoo messenger ID is knghtryde.

#1 Internal and External Wastegates are just that. To give a short discription, they regulate the amount of boost the turbo will be allowed to generate.

#2 You will want a T25 at 6psi with an internal wastegate which they mostly all come with. This will give you the goal you are looking for. I would suggest a Side Mount Intercooler from an S13 SR20DET. LS Automotive ( lsauto.com ) will sell it to you for about $100.

#3 Get a Set of 370cc injectors from a Silvia off of Ebay. This will run you about $50 to $100 dollars.

#4 with the 370cc injectors @ 6psi you will not need any other upgrades to your fuel system.

#5 Get an SR20DET stock Turbo with the SR20DET turbo manifold again you can get this from EBAY for about $250 dollars. Have your friends dad remold the Mainfold and weld it to the KA24DE stock maifold Flange. then have weld you the custom piping to the SR20DET Side Mount Intercooler.

#6 Use the bypass valve on the Stock Sidemount intercooler and have it rerouted to the turbo inlet pipe if you want to sleep the car or leave it open to hear the blow off sound.

#7 Get a boost gauge and install it.

#8 Get a boost controller. If you did everything as explained the engine should be able to handle 9 psi easily and safely.

#9 You should now be getting between 210 to 250 rwhp for less than $1200.

#10 any other questions just PM me.

stick with a T3... a T25 is too small for a 2.4l, and you can find them from alot of cars (z31, thunderbird) but i geussif yo dthe whole sr20 manifold thing you'd wnat a t25 to fit onthe maifold, kngthryde have u ever tried that?

freshalloy.com has alot of info on ka24et's. if you just want a non-intercooled kit realnissan.com has one for 2500. non-intercooled is pretty unsafe and you wouldnt want to run any more then 5psi
but for your psi and price goals it sounds like the thing to do.
and also 370's only fit on DOHC's unless its from a CA18 im pretty sure..

[misnomer]

knghtryde: what do you use for fuel management in that setup? Wouldn't simply droping 370cc injectors make you run rich?

[Nismo240SX]

yeah, isn't 370cc too rich for only 6psi. wouldn't you have to had an ecu reprogrammed or something to let the computer know the right amount fuel to actually inject? i know you can run any cc injectors, as long as the ecu knows that and injects less or more fuel...right?

[knghtryde]

The Stock injectors will run fine for 6psi, but the SR20DET 370cc injectors will allow you to boost up to 10psi safely and accurately.

About the 370cc injectors running to lean. I thought the same thing before I learned from JWT that the stock 240sx ECU is actually programed for 335cc injectors, but the car only came with 255cc injectors.

JWT is the one that told me to drop in the 370cc injectors into the car. They also told me that the ECU will control the injectors perfectly until the 335cc.

It worked perfectly fine for me. Yes I have tried the set up I mentioned it was the first turbo I ever attempted on a KA24DE. It worked perfectly fine and I spent 1200 for the entire setup.

There are alot of better kits out there. I was pushing 237 RWHP from the kit I mentioned.

[rancid240]

This is for ka24E, not ka24DE.
I've searched and read up about this topic alot, just wanted to see what people thought of the particular setup.

[knghtryde]

I've done this same set up for the KA24E, except injectors I used where from the CA18DET, and there is a little more work to it. The injectors do bolt in but there is an extra step that will cost you about $2 dollars to do. I was able to get this set up on a KA24E to push more power than the KA24DE cause of the lower compression on the KA24E. Actually I'm working on this exact setup again. I'm doing it as we speak.

But if you want information and exact instructions in this case, PM me.

Remember...

1989 KA24E 8.5:1 Compression
1990 KA24E 8.6:1 Compression
1991-
1998 KA24DE 9.6:1 Compression

All of the KA engines have forged pistons, rods, and crank shaft.

Yes I know that a lot of you know this information but you will be suprised about how many people don't know this.

the Single Cam KA24 can get more power with the same amount of boost that the twin cam does. And the CA18DET 370cc injectors work, so do the 440cc injectors from the RB26DETT.

The stock ECU was preprogramed from the dealer to handle 335cc injectors, but they where only equiped with 255cc injectors so you will not run rich if you supply the car with Nissan Injectors. The ECU will be able to control the Nissan Injectors you just will not get the full potential out of the injectors without an ECU upgrade. (I suggest JWT) if you are going that route.

The KA24E can pack close to 295rwhp with stock internals...

[knghtryde]

To clarify, the set up that I mentioned before will not get the car to 295rwhp. The set up I worded was for a low budget setup to get between 200 to 240rwhp.

To get 295rwhp you need some extra work that will include other bolt on modifications and a steal head gasket from real nissan.

But that's a really long list that I'm not about to get into on this post.

[rancid240]

so how did you get those ca18 injectors to work?

I dont think I will need them though if I keep it under 7 psi- the whole point of the setup is just to add a little more oomph to the ka24e, not to lay down impressive numbers-

[knghtryde]

If you are going to keep at around 6psi you do not need the injectors, the injectors will only be needed if you are boosting more than that.

The injectors are easily made to work by placing in line resisters on the wires.

You can do all of the things I listed for under $1200.

This is the perfect kit for anyone trying to make real power outta a KA24E.

Jonathan, check this kit out.

Sorry to bring this thread back from the dead.

But im planning on a KA24E build.

I wanna do t3/t4 turbo setup and possibly upgrade the bottom end.

Possibly with real nissan rods and pistons as well as head gasket.

Figured id run some 440's, Z32 maf, walbro pump and wolfe ECU...

Main question would be, other than realnissan, who sells forged internals at a competitive price? I find there are lots of SR parts, but KA24E lacks.
Anyone?

If your going to go near the pistons use the over bored 90mm (200$s for the full set, stock comp.), bust out the nissan motorsports racing cam, which itself is a 20HP gain at 6000k, get some nice springs and ret. so your valves arnt floating. And get the Wolf ECU to bad their 500$s. You can easly it 170RWHP without the turbo if you do a few big things and do some important little ones (Pistons, Cam, ECU, and a decent port job) Then when you bolt that turbo up you will have very little lag. And if you want to be crazy and dont care about your top end, throw in a 4.36 ring and pinion, yumm.

When ever I look at a cheap nicely working turbo setup I look at aceinthehole's setup, its rather cheap, home made and makes IIRC somewhere near 230hp and 250toq (sorry if im way off) and his car is basicly stock expect for the 91 cam trick and the porting, and I think he is running low boost.. but yea, this is mainly my plan and ive been resurching it for a while, so I would check it out :-D

[Gladman]

Bah... not interested in cheap.

I've cheaped out on kits before and its always come back and bit me in the ass.

The cams idea sounds good, ill have the whole thing apart anyways so ill get my cams reground.

I've done work with the guy that does the PDM cams so i should be able to get them a bit cheaper. $100 for SOHC turbo cam.

My goal for the summer is 300Whp. Should be exciting.

[Zemus]

PDM cams are re grinds, eh, i guess thier ok, your better off getting a un ground cam, one that is made with the right lobs.

[Gladman]

i've had good results with regrinds in the past....

[Var]

i dont get how you can increase duration and lift by grinding down a cam even further. can someone explain?

[rancid240]

Wut you guys think of this?
Somebodies selling it on NICO, I think its a good price...

am selling a basic sohc ka24e turbo kit for $1500. Here is what you get:

- Turbonetics T3 turbo with polished compressor housing, and adjustable internal wastegate
- 2.5" downpipe with heatwrap on it
- Bar and plate spearco front mount intercooler ( polished )
- Thick steel log type turbo manifold
- manifold support bracket to ensure that it doesnt ever crack
- All intercooler piping
- Steel braided oil line kit with all brass fittings
- brass oil pan fitting, i will include the oil pan with fitting already installed if you want it.
- All couplings and connectors

[knghtryde]

That's a good price, but how used is the kit. Ask if there's much play in the turbo.
