Hey guys. I have a 1990 9KT 5sp. DI/APC that I've decided to upgrade in the power department.
First, I've decided that I'd like to ditch the T-25 (T-too small) for something bigger. Any recommendations? I've heard of the T-28 upgrade, but I want something that will produce 20+ psi boost up to redline. I was thinking a T3/T4 hybrid would work, and I could find a cheap T3 from an older year 9KT as a core. I already have a 3" downpipe, and I hope that the T3 from the earlier 9KT's bolts up to the same flange.
Next, gonna need some more fuel. Definitely a RRFPR, and I was thinking 24# injectors would work fine. Question is, any one know the specs. for the stock injectors? I know they are Bosch style, but high or low impedance? I'm asking because if they will fit, I can get Mustang injectors really cheap. Also, with these mods is there any need for a bigger fuel pump?
Third, need even more air. Thinking of bigger bore TB and camshafts. Any good source for some cams? I was thinking that the cams from the NA 2.0 might be more agressive, but I'm not sure about this. I would really like the cheapest option on this one. Is there any way to degree the cams (adj. sprockets, etc.)?
Fourth, since I have DI, in order to play with timing I would need a computer upgrade. I will be in Europe this summer for a while, thinking of trying to find a deal on some reprogramming. Question is, can they program both computers (ECU and APC) or just the APC? I'd love to upgrade both and possibly increase the rev limiter (so that going from 1st to 2nd boost comes on sooner).
Finally, for traction, any good source on a LSD? I know Abbott has one, but it's expensive. Also, clutch recommendations? I know the Centerforce one I bought didn't hold up for long, so I'm looking for something better.
Well, that's about everything on my mind this morning. Answer what you can, if you can. Let me emphasize that I am looking for inexpensive things to do--this car is not worth putting a bunch of money into it. Some of these plans are "wishes" and some will definitely happen. The bare minimum is a turbo (stock one has 170k mi. on it and is worn out--only pushes 12-14 psi max above 5000 rpm) and fuel upgrade. Thanks.
