the stock sleeves can handle 15psi for quite a while as long as its tuned well. obviously sleeving is always recommended tho

 

Bump for takin the time to research

 

Specs from Civic Si Int-265 mid Exh-267 mid
Specs from GSR Int-274 mid Exh-276 mid
Avg. custom "turbo" cams Int-280 mid Exh-276 mid
Full zoot n/a cam specs Int-295 mid Exh-293 mid

Those just seem to be the average duration amongst manufacturers on the latter two. One can see why most folks go GSR cams for turbo applications unless they are trying to squeeze every last ounce of hp out of it (usually, these are not street driven cars anyway).

 

i heard that an ls normally will have lower compression wich is healthier for a turbo. and a ls VTEC is built with high compression so it more geared toward Nitrous. so if ya wanna go turbo build a ls.

 

vtec heads are much better flowing.,,,so o with vtec if you can

you actually can use ctr's or itr's IF YOU KNOW HOW TO DIAL OUT THE OVERLAP!

 

Dial it out with what...a dremel?

 

The LS block I have had a Vtec head already matched up to it, in which my boy has.... As we speak I saving up for a head and other various parts. I have already managed to get pistons and rods but 'm not gonna tell all my secrets just yet... As someone mention to me and herr on this site, I need to focus on getting the vtec working right first.... Besides I have found an elecltric water pumps its kinda pricey but hey, I had one before and there was a noticable diffrence.... I love assorted goodies I just dont like paying for them all....

 

That is really pushing it.I knew your car was fast.Now I know you are not scared to break stuff.

 

????????


with cam gears......

turbo cars dont like the overlap associated with NA cams

 

Those specs are suspect to me...Check out what CraneCams has to say about ITR Cam Specs and their CamSpecs
