This thread has definitely gone off the orignal track in the subject of the cheapest way to get a NA Supra to beat a stock SS. TT engine swaps with single turbos aren't cheap. NOS is the only cheap solution out there. Just for the cost of swapping the drivetrains, it would be a lot cheaper to just sell the NA and get a TT. NAs weren't built for racing, TTs were. That is the simple fact. On the same token, they also have 6 cylinder Mustangs and F-bodies for the same reason. Asking a NA Supra to beat an SS is like asking a 6 cylinder Mustang to beat a stock GT.
Here are a couple of pieces of information to keep in mind. First, a Supra TT can run 12's 100% stock on stock rubber by just pulling 1 hose(VSV). Cost for this mod = $0. This single mod usually means 340-360 rwhp. While no one would recommend driving a car around like that all the time, it is fine for the occassional grudge match. Second, a LS1 F-body with just bolt-ons will not run with a BPU Supra unless their is something wrong with the Supra. A typical BPU Supra(Downpipe, boost controller, BCC and exaust) will put out 400-420 rwhp at 18 psi on street gas. That is only $1000-1500 in mods. Intakes, intercoolers, timing gears and a VPC will make a difference, but little compared to what a boost controller and downpipe will do. Those mods are more important for preparing a car for a single turbo to be added later and make the car more durable for long term, but are definitely not essential at this level. If they are making less than that, there are either boost leaks or the turbos are going bad.
F-bodies with bolt-ons will not hang with a BPU unless you consider heads and cam or NOS as bolt-ons. If that is the case, then a single turbo would also be considered a bolt-on. The only F-bodies that I have seen that run with BPUs are with heads and cam. Stock Z06's can't even hang with BPU Supras. It is simple power to weight.
The only "street" Mustang I saw run 9's had a fully built 347 stroker with a Vortech T-trim running a Paxton fuel system. I have seen other Mustangs that have run 9's, but only 1 that was a true street car and not a trailered race car. None of those trailer cars were built for $8K either. He spent more that $8K just on the motor. I would like to find out about this magical formula to run 9's for $8K. For the kind of power it will require, it can't be done with a stock rear end or a stock tranny. Figure over $2,500 just to start with those 2 issues. A real clutch, TKO tranny and 31 spline axles/diff are a minimum at that level. I would also like to see someone able to get 600 rwhp on a stock 302, ie stock heads and short block with just adding a blower and/or NOS. A built engine costs real money and so does everything that goes into a car to complete it. Of course this is also assuming you do all your own labor.
