What is the most you can have a sleeved h23 bored, and what would that make the engine... i know a guy who has a h22 bored to almost a 2.4 ltr, what is the largest bore i can go if i plan to run a lot of boost, and what would that make my enigne????
thanks for the help guys

 

Depends on how Much you want to spend. Ive seen 2.7 H22 Preludes, but it was like 17Grand for that

 

I don't think I've ever seen a H block sleeved larger than 89mm. 90mm might be ok for NA, but there would be no room for error if a problem should arise down the road.

 

i was told the guy down here with his h22 bored to a 2.4 had about 125grand in his motor, he's pushin 780+ horses before nitrous and over 1000 with. i'm just trying to get an idea of what would be the best setup, i'm trying to push at least 600 hp once i put my turbo setup on

 

WOW! true love for a prelude right there!
