ok you said the turbo really increases the torque, now that gets me interested, how if you can theoryize, could i set a turbo up to increase torque but only around the 2000-2500 rpm scale or is this feasible mines a daily driver, and i try to only run around these rpms, sometimes i run close to 3000 taking off, depending on traffic, atlanta is a bitch, go or get run over, would the turbo damage engine running down interstate boosting constantly at 2500 rpm?Don't get me wrong I'm not knocking what you've done (I think it's awesome actually) but I was just thinking about it (and my main interest is the cressidas which have supra moters in them which swap very easily for turbo supra moters)...if you had an intercooler and all the right supporting stuff (fuel, ECU, etc) 7 psi would get you roughly 150hp at the crank (I'm also accounting for the redesigned intake manifold and larger displacement (bigger stroke crank)) at most which through a manual will run about 120 at the wheels. with, as you say, the running problems I'd be suprised if you hit 100 hp at the wheels.
Before you get all angry at me remember the famous words "HP sells cars but torque wins races". In your current state you're probably hitting 150 or 160ftlbs at the wheels. torque is what you feel when you hit the gas, it's what pushes you forward. HP just means the engine can do it while revving high.
I think your next step oughta be get a megasquirt standalone or something along the same lines and hand it to the programmer/tuner. the difference between what it is now and what it could be is as different as what it is stock to what you've done so far.
...the problem is in the inherent design of the 2.5 and it's electronics. 1 bar map sensor only reads up to 14.7psi absolute (aka atmospheric pressure....no boost) and the ECU will be utterly lost. add to that the stock bottom end isn't set up for boost but you can certainly change that. if you ran something like megasquirt for fuel/spark control you'd be set. (I say MS because I doubt there's much support for aftermarket ECUs for the 2.5 and I wouldn't pay for an add-on chip that I couldn't take to WOT and ran like he says.
