Had My Car Tuned!

[JonTurpening]

Short list of mods:

RB25det spec 2

GT3582R .82ar

Jun style intake

90mm throttle body

550cc Delphi top feed low impedance injectors

JGY fuel rail

Aeromotive FPR

Walbro 255hp fuel pump

Tial 44mm v band waste gate

Hallman boost controller

3" ss turbo back exhaust

Top mount exhaust manifold

Apexi Safc 2

Apexi ITC

93 pump gas

Spec stage 3 clutch

Synchronic BOV

FMIC

Z32 MAF blow threw

This is a 2698lb with driver in it 240sx.

We had some problems with the boost creep so we could only set it at 11 psi but as you can see it creped up to 13.5 or so at about 6100 rpms. Also had some problems with my coil packs.

This is wheel horse power not in shoot out mode.

Correction factors were

77deg. F

60% humidity

60" of mercury

Intake temp was 90deg F

Car pulls like mad all the way to red line. I am very happy with the car as is but I'll more then likely pull the exhaust manifold off and fix the creep problem.

Seems like a bit of a waste until you turn the boost up.And a stand alone engine management.

You only making 35hp more power than my car did with a stock turbo.

[JonTurpening]

Was not sure of the amount of boost I can run on a stock rb, so we kept it safe at 13.5. What would you recommend? What can these motors handle??

I am going to be pulling out the motor this fall and building it top to bottom. To take advantage of the set up. SO If I can run a higher boost now let me know!!!

about 20psi depends if you start to get valve float those turbos can run up to 30ish psi. Not sure how well a SAFCII will go just keep an eye on A/F dont get leaner then 12ish to `1 when you are leaning on it.

[NYTSKY]

I wouldnt go any further without a stand alone engine management system.Otherwise you will be wasting you time turning the boost up.

[JonTurpening]

Will the stock motor hold up at that amout of boost?

I had asked my tuner if I needed to get a power fc and he told me with the itc and the safc2 I would not see much of a difference at the level I was running the car. I'll check with him again when I get the coil packs and see what he thinks about running 17-20psi.

I just can't see spending over $1300 U.S for a used Power fc. Then having to spend another $300 to get the tuning software! If need be I'll just get a haltech.

[JonTurpening]

Was that in shoot out mode or at the wheels?

then get a haltech any standalone will be much better. Yes stock will hold you may need to put a metal head gasket on though. Like I said at that boost some people have valve float issues.

[JonTurpening]

Thanks so much! I am way more familer with US market engines. I.E the VQ35, 4g63, 2jz and the like. I'll have to put the money out on a good set of coils first then it'll be a haltech!

Thanks again guys!

I'm happy with the power it's making now as the car is light. Can't wait to get a Haltech, coils and fix the boost creep!

whoops its a gt35/40 (for some reason thought it was a gt30/40) so i would only run the car up to about 300rwkw unless you want to put some forgies in then you can crank the boost push the car well into the 300rwkw range

[GeeTR]

The Yank is calling it a 35/82, (exducer) and the Ozi is calling it a 35/40 (inducer)

How backwards hahahaha

[JonTurpening]

so thats about 402whp. Sounds good!

I've noticed on the dyno thread for the rb25 that alot of guys post up the shoot out mode on the dyno graph. Not sure if is the same as what my tuner is calling shoot out mode or not. Could someone clear up what Shoot out mode on the Dynodynamics there means??

My tuner is telling me it's crank hp. Is this what you guys are calling it??
