hey guys im over in new zealand and have nearly finished by turb set up just wanted to now a few things

the engine is a d15b 1500 sohc vtec
im running a 2 mm copper head gasket with 2 factor head gaskets on each side of that
running cusom intercooler all the usaul stuff and a field hyper r computer is a piggy back computer just wanted to know if it would run alright on 7 psi all internalls are standard and will be tuned any one had trouble boosting on a sohc vtec

 

you're running 3 headgaskets?

take off 2 of them. the d15b isn't stupid high compression. just put the stock one back in.

how much boost = how much fuel. you never mention anything on injectors.

 

I ran 7 psi on my bone stock d15b7 without any problems. With all those headgaskets your low end would be weak and it would take longer to spool the turbo. You would need a lot more than 7psi to make any power at that low compression too. I would worry about all those gaskets being a weak spot and not sealing. Id run one stock gasker personally.

 

holy god.. 3 gaskets.. u got like 5:1 ... not really but still..
my boy has a a boosted d15b7 runs fine at 8 psi with t3/t4 turbo.. we took that turbo off and running t3 now.. that bitch was too big..

 

I own a d15b, will be boosting @ 7 psi minimum soon, max is at 10 psi on stock internal. Now, just get those 2 head gasket away, they are totaly useless, get one stock head gasket, or keep your 2mm and boost @ 9 psi, it should make descent numbers.
No probs about boosting a sohc plenty of people do it here, no probs soon, those little thing became monster under boost, a blast to drive.
good luck, keep us posted, btw, you'll need some fuel management or you'll destroy your engine really reallyreally soon, at least a Vortec FMU with 12:1 disc and like 450 injectors. other than that happy boosting !
