i would personally just boost the LS or swap it out completely for something stronger such as a GSR , ITR, or k20. I have a theory (not really a theory since its been proven ha!) that the LS block is meant to make power throughout the entire power band especially at low to mid RPM .. thus not carrying V-tec . When adding V-tec you basically strip the LS block of its low end power and add minimal power up top. Depending on the route you wanna take (n/a or boost) grab something strong (cough ITR cough) or build on your LS and boost it.Someday i plan to do either an all motor 98+GSR or ITR . Whatever you choose to do, good luck and keep us updated P.S. Your integra is sick.. since i first saw it at the steakhouse.. i was like WOW.. really like it bro!
