Dylan JZ;1837900 said:A turbo K20 or F22 would be a better idea because they're a lot lighter, otherwise aluminum block v8. However, if you plan on trying to extract 700whp like the JGTC guys did, then the 3S was the better option IMO (for 4cyl).
turbo k-series shits out over 400whp at 10psi. I wouldnt waste my time with an outdated 3s.
