i have a 92 maybe 91 integra LS motor in my crx and i was wondering on average how much and what parts needed to do a LS Vtec.

 

The b16 head wil average 500-600, maybe 1000 if you want new seal/gasket/stuff. Another 50-60 for the "vtec conversion" lines and what not, or you could spend good money on a bling conversion from GE, as they sell completel LSV kits now. You're probably lookin at 1500 if you wanna reinforce it/get it built "correctly" meaning reliably, tune it, etc. good luck LSV is hardcore stuff.
