Has anyone built a stock bottom B20/vtec with a B16 head and ITR cams and had any problems?I heard that if you run any cam other than a gsr you mess up the pistons. Is it true?What do I have to do so that doesnt happen?

 

didnt like the last thread?
anyway, i had a turbo b20/b16 w/gsr cams, reved to 8200, with no problems(until it cracked a sleeve of course). im sure someone has the answer your looking for, just give it a little time.

 

Why would you want to leave the bottom end stock, B20's got low cr, you don't want or need more aggressive cam than gs-r with cr so low. I am building a B20Z vtec, putting some 11.5 cr pistons, rods, (make sure you use arp rod bolts if you want it to last), gs-r head with full skunk2 valve train, should be making some nice power, I suggest you raise that compression

 

The reason why you shouldnt use cams any bigger than gsr is because the stock pistons on a b20 dont have enough valve relief .

 

i beg to differ. im running the exact setup u stated before. stock b20 block, itr cams/valvetrain, aebs mani, 70 mm tb, mildly ported head, etc. and ive got probably about 20,000 miles on this motor with no problems

 

Im putting my B20/vtec in a DA also.How do you like yours?What are the track times?

 

i like it. no track times yet. the only track we have around here is an 1/8 mile track and its a shitty track and its about an hour away

 

i have a b20vtec with JE pistons, eagle rods and built head, compression is like 12.8, im running skunk2 stage 2 stuff in the head and it put 216 hp to wheels and 155 tq..... not sure on the track times, ill prolly find out on tuesday or wensday, tranny is being rebuilt as we speak....
