i read the article about why u shouldnt go LS/VTEC. I agree to a point, but I do disagree with a bit of it. It does work! I dont know where he got the RPM issues, cuz I have talked to people with a properly built LS/VTEC's having no problems into high 8,000 RPM range. I have always known the shortfalls of the LS/VTEC. None of that was really any suprise to me. Just realize the LS/VTEC wont last as long as a ITR engine. If it were me building it, I would do it over the ITR in a heartbeat and understand the shortfalls. Instead of a 100,000 mile ITR engine u just have a 50,000-75,000 mile engine (atleast with my driving).
Ok as far as heads go, I would use the B16a head. People say blah blah blah and go with the GSR head. Sure the GSR head flows a bit more. Sure it will make a bit more power stock than a stock B16a head. The last dyno I saw was 6 HP and 4 foot-pounds more torque. Truly its definately not worth it in my book cuz the GSR head is like 700 dollars more (roughly) than a B16a head. can u see yourself spending 700 dollars for 6 HP? I know I cant. Also something to think about is the B16a head has more potential than the GSR head for power. The GSR head dual stage runners are a flow restriction when u get to high RPM's and higher flow rates. Granted we are talking about a DPR stage 5 or Stage 6 port, plus combustion chamber modifications to the B16a head, but at that point the B16a head will eat up the fully ported GSR head any day.
Also I wouldnt turbo it either. The rod to stroke ratio is too poor for a turbo engine. Not saying it wouldnt work. The engine just wouldnt last long. Everyone that I know that turbos the LS/VTEC's they usually go boom (eventually). Why spend all that money to put on an B16a/or GSR head and everything to swap it over when u can just have your engine setup for more boost instead and make more power for the same amount of money u would spend. Besides VTEC heads arent really that great to turbo. VTEC is meant for N/A. It has too much overlap, especially the H22, CTR, and ITR cams.
