i wouldnt even boost a GSR motor. As far as I know Boost + VTEC = problems. I could be wrong though.

Then again most of my experience comes from having Preludes for 4 years and i know that Ludes hate turbo....this could be different in VTEC Tegs.

 

From what I've always heard, B18C1 w/ boost > B18B w/ boost.

 

unless you tune your motor for the vtec to be able to sync, give it a stronger pistons , lower compression, etc ., for a turbo, its not worth it. your going to have too much fun blowing it up. i knew a guy who had a boosted gsr, stock internals, only pushing like 6 psi, and blew his motor aprox 2-3 times in less then two years. The money he spent on replacing/fixing the motor, he could have just used to work on the internals in the block, made it less compression so it could handle such boost. but hey, not my money. but there are alot of variables that go into this. meh

 

WestCoastStyle :rockon:

 

power wise - (no internal work)
b18c boosted with 6 psi > b18b boosted with 6 psi

longetivity, lasting wise - (no internal work)
b18c boosted with 6 psi < b18b boosted with 6 psi

reason - b18c1, as you know, has higher compression. b18b1 has lower compression. thus, with a non vtec motor, you can push like, 1-2 more pounds of boost than on a vtec motor, getttig close to or more power than boosted b18c1 at 6 psi. its not to safe to go with more boost with a high compression motor, other wise blowing it up will become more evident. but hey, i dont know shit.

 

definitely go with the b18c1....gsr
