Very nice mod list.

The car will definitely have the HP to do 9s...but what are your plans for traction?

One step at a time grasshopper....

After talking with Ivan over at AMS he has given me some ideas to consider.

Right now I'm speaking with various higher HP 240SX owners getting their opinions on what's working, and what's not...

C. Anderson · 02-17-2007, 12:21 PM

Whats up Chris, this is Clays friend Chris. Glad to see you have the car again. I know how you can get traction. Send it to Full Race. Cant wait to see it when youre finished.

Yep, Geoff and the guys at Full-Race are class acts. I spoke with Geoff before beginning the build, and he offered some great advice on a wide variety of issues.

We'll just have to see what happens...

But with 240SX's in the 8's and 9's, there's no need to re-invent the wheel, and I will probably copy a proven setup.

godzillarb · 02-17-2007, 02:26 PM

Well...I'm VERY interested in what you come up with, besides awd...that's just crazy.

For now I'm going to settle from some 335 drag radials because the 315/35/17 "performance street" tires I'm running are rather pathetic... but they were good enough to wax the prick in his Diablo on the way home from the hardware store lol.

im not sure what your considering higher HP 240sx's but i am making 520whp detuned w/my rb26 and using Bridgestone Potenza RE750. i love them and are perfect for street driving. After these are done im going to look into some Advans.

700+ whp on race gas.

I will be using BF Goodrich K/D's as my daily driver type tire....

But on the weekends at the drag strip, or at car meets, I'll be on Drag Radials...

335's?

Hell, I'm having problems enough running larger than a 10" wheel without doing body modifications.

I dont see anyway a 335 can fit, without going widebody, or having major wheel/tire overhang.

Wide body , squeezing some 335' would be rad!!

I'm running 315s with plenty of room to spare, but I trimmed the body and am running chargespeed 50mm over fenders

17x10 +12 offset

Sweet man, I like the setup..

By the way, my parents live in Destin, FL...and I'm down there several times a year...

We'll have to meet up next time I come to visit with the car.

godzillarb · 02-17-2007, 04:26 PM

Haha, small world. Maybe by then I'll have the 335s :-D

harleys · 02-17-2007, 05:11 PM

woah, i remember seeing this car around conway or little rock on i-40 in arkansas a couple years ago.

Yes, Underground was started in Searcy, Arkansas back in 2002, while I was a college student.

240sx2jz · 02-18-2007, 11:39 PM

too bad u werent closer to the east coast so you could try some supra killing in your own weight class

. nitrous definately has its place...people that say its retarded shouldnt run race gas, shit they shouldnt even put 93 in their tanks...nevermind meth injection. i dunno thats just me i guess.

Yep, many imports guys look at nitrous like it's only something to be used by mullet having Camaro owners.

It's a simple lack of knowledge, that leads them to feel this way.

At the same time, many import guys are fully aware of it's benefits, and know how to tune for it, and do.

On a turbocharged application, nitrous is great for advancing spoolup times off the line, which is what I would be using it for on the Stage III build. (Next year, if money allows.)

From a roll race, where I am already churning some RPM's, it probably wont be used on this car, since the turbos are not laggy enough not to have this issue.

But on the drag strip, it will become very handy.

godzillarb · 02-19-2007, 07:06 AM

If you're worried about lag / spool up at the drag strip why not just run some anti-lag control software? The AEM EMS has this setting and you could boost to 15-20psi in neutral if you wanted to.

When I get tuned it'll probably be set to boost 5psi or so, seeing as any more would break my shit in a second.

umsports · 03-22-2007, 12:33 PM

Just wanted to update the thread.
Check out the new mod list in my intro post.

We decided to scrap the twins, and instead went with a GT4088R.

This turbo should make the 700whp I am shooting for, and we'll know in the next few weeks.

The block is finished, and we are just waiting on OEM Valve Seals before we start on the headwork.

Looking forward to dynoing the car in the next 4-6 weeks.

Joking....

I did receive a sponsorship, but I truly believe in Eagle's quality, and I have used them on several domestics with no problems.

People on the import boards prefer to use the JDM brands, but the Eagle rods are fine up to about 1000whp on a 6 cylinder.

umsports · 03-29-2007, 07:30 AM

Without a doubt, the biggest aggravation with my 240SX has been breaking axles.

I have in all seriousness replaced the left side at least five times, and have broken on the line at the drag strip twice. This is quite embarrassing to say the least.

I noticed that Duy (1000whp 2JZ S14) and Mark (Mazworx T88 S14) have both ran the Mazworx axles, and they have held up to multiple 8 sec passes without breakage.

"The Mazworx 32 spline outer joint and upgraded inner joint will give years of lasting service. The Kit includes driver and passenger axles, new hubs with ARP Extended Wheel Studs already pressed in, and the Mazworx Inner Joint adapter to make all the parts a bolt on affair."

Considering my car is a street car, and I'm shooting for the high 9's, I figure this setup should hold all I can throw at it.

They are $1799 plus shipping, but worth their weight in gold. 1 Year Limited Warranty.

Here's an image of the pieces included in their kit:

DriveShaftShop does offer their own version ($1599/ rated for 900 HP), but it isn't nearly as complete, and only replaces the axles themselves....which is only half the problem in that car.

http://www.driveshaftshop.com/item170760.ctlg

If anyone wants to post up other manufacturers, I'd love to get a list going.

To my knowledge, these are the only two making upgraded setups for the 240SX.

mayco_86 · 04-11-2007, 09:53 PM

The car sounds like its coming out really strong. Give us so more updates soon.

tommy_thrash · 04-14-2007, 09:48 AM

Hey man nice to see you got the beast back, this is tommy with the SR powered s13 coupe. I met you at centerville a few times.

umsports · 04-14-2007, 10:42 AM

I'll have pics to post up on Monday, but the fully built Ferrea Race Head is Finished. The bottom end is finished.

I am waiting on my Exedy Triple Disc Clutch and HKS DLI Ignition System, and then a few fittings and Y-Blocks from Summit Racing.

If all goes well, the car should be driving on the street in the next few weeks.

We're shooting for 600whp on E85 Pump Fuel, and 700whp on C16.

godzillarb · 04-14-2007, 11:06 AM

At what HP levels did you start breaking axles? This is kinda making me think twice about going to the track without backup.

umsports · 04-15-2007, 03:01 PM

330whp (AKA Stock Boost Pressure on the RB26 twins.)

godzillarb · 04-15-2007, 03:35 PM

uhhhh...shit. Good thing my tires aren't too sticky.

I'm guessing lots of wheel hop and hard launching?

good luck, let us know how laggy that big old 4088r is

dont get your hopes up mate, it will be a bit of lag even with a divided setup

also i thik you will need two banks of 72 lb/hr injectors so youll need to modify the intake mani

or just get a really good external pump to a surge tank ot just on top of the intank pump for boosted fuel pressure,

but 1000cc is kind of treading the line, consdiering the amount of power and CFM's you will be flowing.

**edit** you have that big of a problem braking axles???

I havent had trouble at all over the years, even at 400 ft lb torque at the wheel levels.

Did you use slicks and a quiafe lsd or something?
