u can bore it to 90mm but its not wise. i dont know anybody who would even on aftermarket sleeves.

**Vteckidd** · 02-28-2009, 09:44 AM

hell no you cant, even with sleeves max i have EVER seen is 87mm

**Crosswyse** · 02-28-2009, 11:22 AM

well thats pics of the block already done Its a B18C1 block bored and sleeved. The custom pistons are already machined.

Good luck trying to get that head gasket to seal for anything lenght of time with any kind of power other than maybe N/A.

**green91** · 02-28-2009, 03:04 PM

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

**Vteckidd** · 02-28-2009, 03:13 PM

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

**EmminoDaGreat** · 02-28-2009, 03:52 PM

grimes did it.

**Z U L8R** · 02-28-2009, 03:57 PM

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

**Z U L8R** · 02-28-2009, 04:28 PM

i just walked over there with my digital calipers.

the official weigh in

it's 3.410 inchs = 86.62 mm bore

with 4mm of sleeve inbetween the cylinders

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

good luck

**helcat17** · 02-28-2009, 06:41 PM

let us know how long it lasts

**Nick Jeezy** · 03-01-2009, 02:14 AM

man everyone is a bunch of debbie downers.

**speedminded** · 03-01-2009, 09:34 AM

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
