I was wondering what all I have to upgrade on my car to run 14 PSI the 2.87 pulley on a V2 thanks Brandon

 

370's Injectors
Z32-MAF
JWT-ECU with a raised Rev limiter
Cold Air Intake

Ian just the other day hit 14psi, so wait for his imput

thanks matt, I have the ecu but I will have to send it back to get a S/C program put on it, how much will the injecters run...and you think you could get me a link for the z32-maf
thanks Brandon

 

If I were you, I'd leave the NA program on there... my 2 cents.

 

yeah, the s/c program has probs w/ timing

ebay or procarparts the zMAF

 

I didnt know that I could do that thanks bags, I have heard that it will detinate because the advancement in timing, how do I make it work.
and to be conpletly honest im not exactly sure what the Z32-MAF is im guessing some kind of mass air flow sensor? I am trying to understand everything before I boost
Thanks Brandon

 

Well, I have not heard of that. Stock timing is conservitive enough. Now, you might want to think about the J&S unit to pull 1/2 degrees of timing.

If I were you, I'd get the N/A 7200 rpm redline ECU and that's IT.

I'd use a SAFC to tune the 370's exactly where you want them. And with the Z maf, it's all gravy.

MAF= Mas Airflow Meter.. it's the black clyinder inline with your intake plumbing.



edit.. I am assuming you have an FMU and upgraded fuel pump.

4:1 disk on the fmu with the 370's and the SAFC removes fuel.

 

I have the 7000 red line the jwt pop upgrade and I dont have anything as of yet I was wanting to find out what all im going to have to get, I plan to purchase a used V2 within the next 3 months and I figure I should find out what all I need and get that stuff first. thanks Brandon

 

555cc injectors, Emanage/ a JS and aftercooler

 

how much you think im lookin to spend on all of this if I get the S/C for around 3000

 

injectors $500-$700
E-manage, support tool and harnesses $500
J and S $400
Aftercooler $800-$1000

 

Bags why dont you like the JWT S/C program ??

-matt

 

I have ZERO personal expereince with it.

However, from talking to 1 individual on this board in person about it, AND reading lots of posts on this board and an sentra borad about it, it "seems" everyone with one loses midrang hp/tq due to the timing.

I maybe 100% wrong, but I don't know how to explain the power loss then.

It's "seems" JWT is pulling to much timing. Now, with that being said, I would pull 1 or 2 degrees @ 14 psi. But, that would be with emanage or J&S. Which BOTH are tuning/safety devices.

Hope that helps

 

thanks man, could I get the S/C first and run my stock ECU and worry about this stuff later, or could I not do that.
thanks Brandon

 

it all depends on how much boost u trying to get to. with stock pulley or even 3.3 pulley u can just have S/C and not worry about intercooler, emanage, or fuel issues or even upgrading spark plugs. Recommended but not necessary. I know people with S/C running 3.125 pulley with stock plugs and stock fuel system. But they just dont beast the car and its not a daily driver. Best thing to do is not do anything until your car is ready to handle full power....cause you will be tempted

 

thanks man, Im sure I would be

 

Wait a sec...

If you have the 370cc Injectors, wouldn't you need a FPR to tune down the FP to make it run normal at ilde?
Or did someone figure out that the 370's + Z32 MAF and stock ECU work together?

I'm running the JWT S/C ECU and have nothing to compare it to - but my midrange seems pretty fat.

Now I just have to figure out the A/F leaning out up top problem - since the Z32 Programmed JWT ECU and MAF don't seem to work on my car.

I'm hitting 14PSI, but I don't do it often because I'm lean up top - I usually shift by 6500RPM.

370's+zmaf+a32 ecu=stock

or at least it was close enough to tune with the safc.

but with your 2.87 you might need something else (do you have a walbro, cuz then you would need a fpr)
