Ok, do I go with the b18b or the b18c? I know the GSR engine has a higher comp ratio, but how much more boost can I realistically run everyday on the b18b? Will I be able to easily make up and exceed the power I would get from the GSR plant on 7psi using the LS engine with stock internals? If so how much psi would I be throwing at the LS motor?

Also I was only looking to run around 6 or 7 psi daily, how much of a hp increase should I expect on each motor?

BTW, I have a HKS turbo. It is basically a Garrett T3 that HKS has "reworked" along with intercooler, HKS external waste gate. Im still looking for a BOV (any suggestions) and a manifold. Also if it helps this is going into a 94 civic EX 5 speed.

Sorry, I know I have alot of questions and Im kinda all over the place, but I would like to do this right the first time and not have any regrets.

 

What, cant anyone answer this question? I know someone out there has got to know, or at least post your opinions.

 

Which engine? It's all up to you and how much you want to spend.
tuned properly the b18b can handle about 12psi.

Hp increase depends on the tuning.
