Look at how thin the sleeves are between cylinders....

Then id like to know who sleeved it. Stock bore is 81mm, most guys go 84, RACE cars run 86mm, PRO cars 87mm, never ever heard of 90mm unless it was an H or K Series.

In for more details

that doesnt look like 90mm to me... it looks to be about 3.25-3.3 which would be from 82-84mm

no reason too do it, you can make 800whp out of 84mm, why be different?

good luck

90mm lolol! What compression? It would crack in between the cylinders with any amount of boost. I'd give less than a day.

Now 86.62mm is believable. Still retarded but whatever. DD?

5 years ago I posted a dyno vid on here after we bored a B20z to 86mm for RSX-S pistons using an undisclosed stock connecting rod, topped with a built b16 head. N/A 207hp/155ft-lbs :ninja:


man everyone is a bunch of debbie downers.lol! Coming from someone that's never made a knowledgeable contribution to the Forced Induction [or NA] forum(s) other than one post regarding a rotary engine. :goodjob:
