You will need: B16A or B18C VTEC head, along with the TB, Intake manifold, ECU, Distributor to match.

If you want a reliable build, get some forged rods, or at least shotpeen your stock rods and use ARP rod bolts...they can handle 8k rpm.

You can use either a b16 head or a GSR head. The GSR heads are harder to come by, and more expensive. They will yield a slightly higher compression over the b16 head due to a smaller combustion chamber. Both heads flow very similarly to one another. The GSR head uses the dual runner intake manifold, whereas the b16 uses a single runner. If you get an older first gen b16 head, replace the valvesprings and retainers, cause they'll be old.

There are a couple good articles on LSVTEC builds. If you're gonna build this motor, you better be prepared to do it right. The stock LS bottom end cannot handle 8000 rpm.
