i have a B16A2 in my eg 4dr right now and i also have a B18A1 in my garage. should i build ls vtec for turbo or stick with the b16 motor? if so what pistons should i use in the ls? found wiesco pistons with eagle rods for $740ish...is that a good combo for ls vtec?

 

If you already have the b16 (which you do) I would use that.They are a tuff engine and make good power with the turbo.They have strong rods (and bolts),and a good stock intake manifold.

 

i have an untouched B16 and an untouched ls. if i was to build either...should i build the ls vtec or the B16 bottom end...?

 

The ls will make more power all else being equal,but the b16 can be a little cheaper to build.Lots of people have made good reliable power with stock b16s.If your going to build up one than the ls/vtec is the best choice
