Looking to build a b20 turbo. Will probably be a long term project. But my question what's the best output you've seen for a b20 turbo? Post Dyno's or links if you can. Besides new rods, pistons, blockguard etc. what do i need to reinforce the block for heavy boost (say a good 15-18lbs)? Thinking of dropping it in a crx.

 

blockgaurd wont cut it...you pretty much have to sleeve b20 blocks or they break. They have super weak sleeves.

But once you do that..they are super fast. My friend ran a 12.6 @ 112 in a full weight full interior 95 coupe on small 14" slicks. That was at 10psi and 91 octane pump gas. On street tires his best was 13.08 @ 116..also on pump gas and 10psi.

broke b20 block after 12,000 miles of boost - 10psi.

ouch, whats the sleeving process and how much?

 

wow..... you got 12,000 miles out of that......

my b20 lasted me 1300 miles ALL MOTOR before my sleeves cracked

but now its sleeved and soon to be boosted so

 

Its the process of cutting out the stock sleeves (removing them all together) and replacing them with huge iron monsters..they dont crack and can hold 45+psi of boost. The cost is around $700 -> $1500 depending on who you go with. There are alot of different sleeves out there now, golden eagle, AEBS, darton, JG, and a few others. I like golden eagle sleeves personally

4 Stroke put up some awesome pictures of his block he was selling...which is a golden eagle block.
