a friend of mine told me you could boost 13 lbs on a stock b 20 before you would need to start worrying about doing anything with the internals, tahnkz

 

Well it really depends on what turbo is being used....

13lbs on a 14b turbo is ALOT different then 13lbs on say a SC61..

The only problem I seen with boosted B20 engines is that the sleeves are alittle to thin for high horsepower applications.

 

have a t3t4 turbo and ill problaby need forged sleeve if i want to get to my goal of 500 hp....???

 

yes you will need to sleeve your block if you want 500whp

 

were would i be able to find internals for a b20 i been looking online not that many places?

 

check out Camp1320.com

 

what about a b20 with a t28 at 14psi will the block and internal handle that?? Also power could i look for with something like??

 

Its less about psi and more about power. You will get different power levels at different psi depending on the turbo...people will argue 8psi is 8psi all day but what matters is the quality of that 8psi charge. The efficiency of the turbo make a cooler denser 8psi with a greater oxygen content and its ability to draw out exhaust gasses is what counts much more than a "psi" number. People may argue with me but properly tuned the block will handle 300-400hp.

 

3 months on 12.8 lbs on a stock b20. To4E 70 a/r. Motor is starting to smoke at start up.

 

300whp~ is about where id stop on a stock b20

 

To the OP: If you're looking for 500whp, get an B18a/b/c and build a simple piston/rod combo. You wont have to sleeve for that power goals; whereas, on a B20, you'll be lucky to break 350whp without sleeving
