I already have a B18C1 turbo and i was thinking I wanted to resleeve (still stock bore) the b18 motor with Golden eagle sleeves and build the bottom end up so i could safely boost more...now i have come across a b20 bottom end...now the money not being an issue, beause i have the bottom end already, which would make more power safely...building up my b18c1 as stated above or resleeving the b20 with golden eagle sleeves (again stock bore) and pistons and rods...and doing a crv vtec with the gsr head...both being turbo??
I have heard that the b20 can not rev as high but will the resleeving handle that? Plus i have seen a resleeved and built gsr motor on around 21 lbs of boost hit hp numbers near 420 with injectors maxing out... so with bigger injectors it could have made more...but with being that this car is a daily driver which one would be more reliable and make the most power? Advice needed and greatly appreciated...

The other thing is for all the b20vtec turbo owners..where did you take your two oil lines from...one of my friends did one and had trouble hitting vtec because his vtec oil line and turbo oil feed used up too much oil for the oil sending unit on the back of the block....

Thanks,
Chris

 

b18c sleeved and bored to 84.5mm=2.0L

 

I really want to try to stay away from boring out if possible....

 

within the past two years of reading turbo and spports compact and now these forums, the rage seem to bored 1.8's or even 1.6's to 84.5mm. it seem to be personal prefence. a bud of mine has built a few b20 turbos. nice hp and torque numbers with about 10psi on stock internals and non vtec head. check out december sport coompact car, there is a making b20 351/263 at 12.5 psi. 2.0L either from bored out b18 or b20 block.

 

Built, bored, B18c is a better block design if money is no option.

 

ttt...I really need some advise...those with experience...

Thanks to the other guys who posted....

will this have about the same amount of torque that the stock b20 has?

 

i would do the b18c to 84.5mm that is what im running and i love it.
The b18c block is better it has the oil sputters and the mane cap guarder(sp?) the b20 doesn’t have them.

i dont know why youre trying to stay away from boring the block to 84mm. if it were me and i had the option i would sleeve a gsr block to 84mm and call it a day. aftermarket sleeves can be bored usually to about 85mm safely so that is definitely not a worry(stock sleeves are a different story of course). a gsr block basically has one advantage over b20 and ls blocks...it has a main girdle thus allowing to rev higher with less worries. oil squirters arent really an issue with good forged pistons anyway
