Debating on building a b20 turbo engine. P8r head,forged pistons,forged rods,venom intake, arp head studs. Heard alot of debate on how much psi to run with stock sleeves. My car is OBD0 right now, and i had a b18a stock 11-12psi, DSM 450's tuned on a VAFC with a wide band monitor. 8.50 et. in an 1/8 mile on drag radials. Its a ebay T3/T4 turbo .63. I don't want to build this B20 and have it lose a sleeve with all that money in it. I know If i had a better tune my car would be better just they way it sits. Should i convert it over to OBD1 and get a chrome tune? I really want to run this b20 on 12-15 psi but if i can't with the stock sleeves then i will prob build up the b18. Thanks for any help

You can not run that much boost on stock sleeves of a B20. The B20 has the weakest sleeves of all the B series. You would do better to convert to OBD1 and Upgrade the B18A1 and run Hondata. I wouldn't run any more boost than you are now on that block though. If you are looking to upgrade your boost a good bit then sleeve your block you have now. If you are looking to posh past 15psi though, you should invest in a better turbo setup. Ebay kits are decent if you get your car tuned and stay at low boost.
