How much psi stock could i run in a B20A5???

To do what? Blow it up?

100 lol jk. how many miles are on the motor?

just rebuilt... so around 3 k

ive heard they got weak sleeves annd cant handle much????

probably couldnt handle very much. dont take my word for it but i wouldnt go over 5-6 psi. try asking the guys in the forced induction forum they would probably have alot more answers for you

i prefer to run the psi equivelent to the hp that the motor puts out.

so in my h22a i run 200psi...and it is fine!

6 or 7 with a proper tune

You can boost a stock block B20A5 depending on the condition of your engine to 6-7 maybe 8psi. If you want to go higher, then you must do a rebuild of all your interenal parts like rods, piston & rings, valves, port & polish and so on and so forth.

You must take into a consideration the condition of your engine like oil leaks, compression testing and so forth before dropping a turbo kit on to your engine.

There is a company that makes the custom manifold and downpipe for the 3rd gen preludes.

http://www.lsdmotorsports.com

I personally have purchased from them and they have the 88-91 preludes on their site for some aftermarket parts. Check them out.

And here are some dalily driven boosted 3rd gens for an example, please keep in mind this all depends on how you do your setup:
