An LS/VTEC or CR-VTEC can have any of the following heads:
B16
B18C1
B18C5
prolly a B17A though ive never seen it.

A CRVTEC (B20B/B20Z block) is very good for N/A as well as Turbo.

 

cr/vtec bad for all motor huh.
b17a is a great head for cr/vtec.It is great for turbo though if you use the b17a crank for optimal rod to stroke ratio for turbo.
i will sell you a full b18a 130 hp 121tq with axles for 1000. thats 1500 less than the b18b.b18b 140hp 127tq.with 1500 you could kick you could wax that b18b ass.
