I'm really interested in the import scene and I'm planning on buying a Del Sol S in the near future (probably one that's been through a wreck where I can get it cheap and add my own aftermarket body kit). I have read up quite a bit on the CRV-Tec or LS-Vtec frankenstein engine, and I came across importbuilders.com. They sell a built LS-Vtec with several aftermarket internal parts (pistons, cams, etc). I was wondering if its worth buying it from them, or if its best to grab a B16A (or just buy the Del Sol VTEC) and a B20Z and just build it myself. What are the price differences and what would the performance differences be?
