How Much Boost

[vtecchef]

I know a stock D series can take upto 7 psi.
I know a stock B series can take up to 14 psi.
But what can a stock H22 take???

I wouldn't run a stock B at 14 psi. In my opinion, if you are bone stock besides the basic airflow stuff, then 6lbs. If you want to bump it up a little, you can stay on stock internals but upgrade your fuel system and push about 8lbs.

B16 shouldn't run more than 8 PSI STOCK
I have known ppl with d series engines and stock internals putting 10PSI's

well you can't tell people what psi is safe if you don't know the size of the turbo.

friend's running a d16y8 on ten psi and no probs so far and it's been over a year

Its all about tuning.. if you can have the car tuned well and run higher octane you can push the limits a bit..

but we won't know the limit till the motor goes.. and every motor/setup is differant.

Its all about tuning and fuel management.

Actually i know quite some fellas running 10 PSI on a stock block D series..

There is a guy at Honda-Tech that dynoed 260ish WHP @ 12PSI on his Stock block D16Z6...but guess what..he has Hondata as Engine management..Again..tunning is the key

I am running 9.5 psi on my stock b18b pushing 240 to the wheels. No problems yet, I totally agree that tuning is the key but I wouldn't run more that 8-10 psi on an h22. Run more if you want but don't expect it too last a year or two.
