I have a 94 3000GT SL. Mileage is 103K. So far i have added the injen intake system for it. It said it adds 12hp and 10 torque but to the crank, how much is it to the wheels... like half of it?Gives u a nice sound as rpm climbs.On 3sx.com they have headers for like 600-700<are they any good? and also is borla the best exhaust you can get for that car? its like close to 1,000 which is crazy. I'm planning on putting headers and borla cat back with hi flow cat by random technology also from 3sx and wanted to ask how much hp do those 3 things add to the crank and how much to the wheels, and how much hp does the lightweight crank pulley, not the one from unorthodox racing. If anyone has a non-turbo or knows of any good mods, such as bolt ons, etc.. please let me know what you recommend after intake, thank you, and let me know how much would a vr4 cost about from 94 and up.

and last, if anyone wants to see how you can build up turbo and non-turbo 3000gt go to dynamicracing.com

 

definitely go with the headers. they will make a very big difference! i may be wrong but my friend told me something like 25hp. the borla exhaust sounds nice but i personally dont like the tips. also for 94+ VR4 ur looking at $9k for an ok 1994. any other higher year in good condition with low miles and you'll be lucky to find one for $12k

 

Replace the CAT with a test pipe. Big Difference.
