all i have is a turbo cam,can anyone tell me how many psi would be safe to run on my car???

 

I would say like 6-8psi, but that depends on your tuning like anything else..

 

Like Tgreaves says 6-8. I honestly wouldn't go past 8psi. Remenber The d15b is the high compression of the sohc motors as far as I know so high boost and high compression don't mix.

Get the car together and take it to a tuner/dyno.

Im actually impressed with your question.. You said what engine and what turbo you have an asked for a psi.. Most people just say "how much boost can I run on my motor" without telling the turbo and sometimes without what engine..

 

You cannot boost over 8.625 psi

If you do, you're motor WILL DEFINATELY BLOW UP as soon as you drive it

anything under that and your motor will last a really long time.

BS I know someone who running over 10 psi on stock internals.

 

i ran 10 psi on a stock d15b for months without any problem. I was running a t28 with 310cc injectors, greddy blue box.... what type of management u planning on running?

As long as you have a good tune, it is fine to run a high compression. A local tuner runs 10.6:1 on his shoc. Boosts like 10 psi on his d15.

come on, he's obviously joking...precisely 8.625? and a bit under that will ensure engine longevity? haha, good one 200GSRT

 

somebody needs a mushroom stamp

 

I've been running 10-12psi on my D15b for over a year now. Turbo is a T3 60trim 60ar. IMO its all in the tune.

Thats what I'm talking about that little engine that could.

 

i was planning on using some bigger injectors and also the greddy blue box, i really dont want to go over 10 i was thinking that that 10 was the most

 

It's power, not PSI. PSI is irrelevent.

Is it a JDM D15 or a D15B2/B7?

The JDM D15's are supposedly a little stronger because of larger main bearing sizes than the USDM D15's.

This man is correct, it's all in the tune. You could push 230WHP easily on a D15 with a T28 (From an SR20, I presume?) , but detonate once and good bye block...Many people run 200WHP daily without problems on a conservative tune.

Correct, but given the motor and the turbo that is used, you can kinda guess what a safe psi would be to run..

 

i was thinking in running with a y8 manifold, y8 fuel rail, venom injectors, pressure regulator and a obx cam

 

I've been running 10-11psi on a mini me swap with a 15g greddy kit with absolutely no problems. Using dsm 450's with an AFC to tune, and a DH-racing head, and my cars C/R is roughly 10.5-1 they say. I used a wideband to help tune and it runs great. Def. agree, its all in the tune. So be careful, retard your timing just a tad or run stock. I have my retarted just a little to compensate for the AFC jacking the timing.

 

i have a jdm d15b with a t3/t4 .57/.63 trim turbo on it.

it builds full boost at 5k and pulls strongly through 7800 rpms.

im running all stock internals with dsm 450cc injectors.

any questions just ask

car runs just as good as the day we put it together..

 

psi doesn't mean ****....keep it under 220whp and you'll be fine. That seems to be the point of no return on most D series builds unless you're lucky or your setup is stellar

 

I thought 10psi was a minimum on stock d series motors?

I ran 12 through my stock d16z6 for a year with no problems. Turn it up!

 

we have a d16z6 that makes 340whp..

as far as turn it up.. im getting the D15b dyno'd on 15 psi tomorrow.
