Im a weekend mechanic who likes to tinker. i do NOT race. I presently have a stock b20 combined with a standard greddy td04 turbo, Zdyne gold, walbro pump, 450cc and its intercooled. I run a 2.5" exhaust with no cat.

The b20 is smoking at idle and while shifting so i feared damage. After a compression and leakdown we found incredible #s. The highest leakdown # was 3% and compression was all around 170. My guess is that i need new stem seals, but i digress...

Do i need to resleeve the b20 block? I'm thinking of putting in forged rods and pistons and pumping boost to 15lbs. At this level, do i NEED forged rods and pistons? Can i just post the block? Should i get a better turbo?

Please keep in mind that i barely ever shift the thing over 6.5k rpms and would like my boost as low in the rpms as possible.

Thanks for your help!

 

If you get some good engine managment, you could run 15lbs on a bone stock b20!

 

thanks for the info!
