Hi All, Well I am finally getting close to building another Z. Now that the prices have risen 10 fold or so, I figure I'll spend my money... LOL. This would be my 4th Z car. So, I am looking into doing a complete build on an S30, probably a 76-78, as I just cant justifying tearing up a 240 now that the values are through the roof. I am looking at a complete build, engine, tranny, suspension, brakes, etc, etc. I am thinking about a few different motor configurations. Ideally I would like to see RWHP in the 375 to 425 area, and torque somewhat commensurate with those numbers. I have thought about a NA motor, but not so sure I will see those numbers from an NA motor. As I hate turbo lag, but love the top end of a turbo, I was pondering a twin scroll type of a set up. My budget is in the $15K to $20k area for the motor. As many of you on this site have much more experience in this area than I do I would love to get some input from you as to what your thoughts are on this project and which way would you go, NA 3.2 motor, slightly built RB series motor, single twin scroll or twin turbo? Also, if I decide to go RB who is a good RB engine builder out there, I am in the Washington state area. I should add that I am not looking for a drag car, but something more like a solid GT car that can also handle some light track day fun. Thank you in advance for your input.
