ok i know that LS vtec is Integra LS motor which is a b18a right? is the vtec head a gsr b18c ? ...im just trying to understand how the Ls vtec works just becuz its a nice thing to know ...i heard that the lsvtec jumps displacement up to a 2.0 is that true top?

 

To answer some of yer questions.......

LS vtec is Integra LS motor which is a b18a right? B18a or also B18B
Is the vtec head a gsr b18c ? The head can be any Vtec head, from a GSR, SI, ITR or CTR
lsvtec jumps displacement up to a 2.0 is that true to? In an LSVtec, the displacement stays at 1.8 liters
hope i cleared some of the clouds for you

The whole point of doing an LSVTEC is to keep the torque of the LS and adding the top end pull of vtec. The ls motor displaces 1834cc while the gsr is 1797cc due to a slightly longer stroke, resulting in more torque. I've read about LSVTEC's makeing just as much power as itr motors. The only drawback to the lsvtec setup is that the ls bottomend was never designed to spin above 7200rpm and they dont have the oil squirters under the pistons like the vtec blocks do so they have a tendancy to burn rings if the're revved above 7500rpm frequently. Hopefully that helps.
