nasa driver with swap questions

[kognition]

Welcome to the forum. It sounds like you do have significant track experience, which means you would be a fast learner. Nothing wrong with starting out stock to get aclimated with the car. S13 or S14 are both great cars to track. It just comes down to personal preference. As far as your being on the fence about getting an Evo or a S Chassis, at the moment.. the fastest car on any Time Attack circuit here in the states is the Magic/JIC S15. It is a SR built by Tomei of Japan. It just took the all time fastest lap recorded at ButtonWillow away from the Sun Evo. IMHO RWD takes significantly more brain function to track than an AWD car. Once you track a stock SR, you will immediately want to begin adding power to it. You will also find that most owners here tend to do their own engine work/planning. Good knowledge base here at Zilvia. You can easily get 350+ on an SR with a few good upgrades and not go broke doing it.

Its basically down to the 240sx and a miata, but im 6'1 and my knees clang against all kinds of stuff in the miata so its about 80% in favor of the 240 right now. i have always dreamed of a swapped 240 and think they look amazing with the silvia front end. and considering i could either get a 150 + mile miata and then have to spend another 3800 on the vodoo turbo kit and hope the motor doesn't go to the crapper, or just purchase a jdm motor with alot less miles and already turbo'd for the 240, the advantage sways in favor of the 240.

so with the background info and intro behind me, i want to get some advice about what motor i should swap into the 240 if i want to run in nasa events. like i said i am currently in hpde but i am working towards getting my racing license and moving up in class in the next 1-2 years.

so what engine is better suited for nasa road racing events in your guys opinion? the blacktop sr20det or the rb25det? i have heard you can make 300whp on a sr20det pretty safely on stock internals, but the rb can go up to 400+ on stock internals, but that is sort of aside from the point. which engine works best as a well balanced track engine? that the main question. thanks in advance. also, what kind of power can the rb20det handle? i have heard 350 or so also, and if that is the case, whats the advantage of that motor, or disadvantage? its much cheaper than the others, any reason for that? is it just because its older?



p.s., before i get flamed i have been reading these forums religously for five days but haven't really found an answer to this question. if you don't want to help out its cool, but if someone does, thanks mucho.

preparing to get , but hope i can get some love.

So getting that the S15 is finally faster than the GMG Porshe driven by Sofranos? Must of been at the last Redline TA which I missed. Good job Sofranos is one tough customer.
