right now i have a 00' sohc w/ a custom T25 kit boosting @ 5psi. i was wondering how much can my stock internals take? will a INLINE PRO head gasket help me to boost higher? right now for my fuel setup i have stock injectors, Bosche hp inline pump, and a Vortech 12:1 fmu. what will i have to do to be able to increase the boost a little bit more and still be reliable?

I know a guy with a D15B running 8-10 psi. but remember it has to be done wisely, and you have to know how to tune. you just don't put a boost controller on there and up it to where you want it. Definetly get your self an EGT and A/F gauge to monitor your engine.

Oh yeah he is doing this with out a standalone, only an FMU, and fuel pump. Ran it all last year no prob at 8psi no prob. Although towards the end of the summer he broke a ring land (can't remember which cylinder) when he pushed the boost too much. Good thing for spare parts hey.

This year he is hoping for 12psi daily with no intercooler either, but he is running an alcohol injection setup.

Good luck with it.

i am planning to run on low compression pistons with intercooler on a t3 turbine. How much boost can my sohc take???

D-Man

if you get rid of the stock injectors,fmu and ecu and go with a programmable ECU like a AEM,Accel,Haltech etc and like 450-550cc injectors,with that,a stock D16 will hold up to 14psi(mine has for almost 40,000 miles on a 62,000 mile engine i purchased from a junkyard) ,forget the inline pro head gasket,waste of money cause the compression ratio is fine and the stock honda gasket will hold,whats gonna fail first before a headgasket are the pencil thin rods equipped in a D16,theyll snap if u push it over 14psi

I agree with D-Man, boosting on the SOHC is fine as long as you plan it out and use a standalone. Then you can really pump some power out of it!!

how much would a Haltech cost? is it plug and plag system? would i still need that if i decide to leave it at 6-7psi?

.. for 2 seconds on a d15b7. i dont think I need to tell you what happened though.

7psi max on stock internals w/o standalone is somewhat reliable.

ive been running 9psi daily on mine for about 6 months
been running fine
i plan on getting a standalone unit, probably the aem ems one and some new injectors
i want to try to get 12's
i might take the risk of pushing it to 14 psi but then again i have a greddy kit and im not sure if it can take that much abuse all the time
so maybe just 12 psi daily and at the track up it to 14

Definitley get an A/F and EGT gauge. If you can tune right you should be able to run up to 1 bar with little worries.
