is a turbo b20 reliable and how much power can it put out and what set-up do you suggest? need help can't find anything

 

Just get a b18 block and get it sleeved to 84.5mm, with good tuning it will be reliable. Im doing the sleeved b18 with a Ls head, endyne FI pistons/rings, eagle rods, clutchmasters stage 4 clutch and flywheel etc. Im going with the drag III kit and hondata 4b with AVC-R boost controller. I plan on running 10 psi on the street(maybe 15psi accasionally) and 20psi (well tuned) on the track. Good luck and do allot of research!

 

What B20 are you talking about? I have a turbo on my B21a1 which is just a bored out B20 with fiber reinforced cylinder liners and a solid deck. Or are you talking about the CRV engine?

I've heard of Prelude B20's standing up to 9-10 psi of boost fairly well.
