Okay, first off lets start with the Type R motor. I was told this is absolutly the worst engine to turbo, though I don't know why. Could someone please explain to me why this is a bad motor to turbo? What would be the best motor to turbo?

Secondly, the LS Vtec. I figured this was pulled straight out of another car, but my friend at a local shop told me it's a hybrid. Is this true? What do they do to make it a LS Vtec instead of a straight LS?

Thanks guys.

 

Type-R Motor has to much compression to be a good Forced induction car compared to other options. This isn't to say people are not having luck with them. I personally would turbo a GSR motor but LS motors take boost well.

LS is a non VTEC motor. To make an LSV you put the head of a VTEC motor on it. B18C5, B18C1 and B16A are the VTEC heads used.

 

In a way I agree with Asahi, in that there are so many other options that make more sense (and are more economical), especially if you don't already own a Type-R. On the other hand, my R has been boosted for about 3 years.....on stock internals..

 

the reason lsvtecs and crvtecs are popular is because of the long stroke of the CRV/LS motor. This translates to more torque output... Coupled with a higher-flowing VTEC head, upgraded internals to withstand higher revs, lsvtecs and crvtecs are real powerhouses.

The B18C5 can be turboed successfully, but only with very good tuning. With a high compression engine, theres less room for error before you start to cause serious engine damage, so the tuning has to be spot-on. If tuned well, the c5 will make tons of power... more than a comparably boosted c1 or B, but its harder to get there.

Sensei, got any links to your car/dyno plots/etc?

nice and linear.

 

A far more productive discussion would be to say what kind of car you have, what your horsepower target is, how safe you want it to be from blowing up, and how much you want to spend to get there.
