4g63. Best bang for the buck. Toughest engine on the market. HP/liter unmatched. 140hp/ltr from the factory. Mod potential 1100whp. Sheps car uses a 1989 motor 2.0, 11/1 C.R. 56psi boost. A 7.0 motor would have to make 3850whp to match this feat. Very impressive motor.
I like the new 5.0 liter bmw v-10. 100hp/ltr from the factory. I also like the straight six M3 motors. The v-10 comes in a platform that just insnt going to see much as far as modding goes. The m3 engine is a proven beast. Much like the supra.
Not a big fan of american muscle. The new Vette is impressive when comparred to supercars. The ls7 motor is impressive offereing from the factory. But 7.0ltrs is huge. Its only making 72hp/ltr.
