Dude,i wouldnt take anything from me. Everything i ever do *****s up one way or another. The only real thing i would tell you is just buy a v8....but thats just me.
I`ve put 41,000 miles on my 98 3.8 since i procharged it. the car now has 72,000 on it. i`ve had no problems with the procharger 11 psi kit the power is great compared to stock and milage is only 2 mpg less than the stock steup.
the only trouble i have now is the 4R70W needs rebuilt. i`m dynoing right around 260rwhp and 290ftlbs of torque with a good tranny. it not putting that power to the ground now though. but that`s my fault i`ve been hard on the tranny and have been trying to give myself an excuse to swap in an 8.8 rear but the 7.5 with 3.73`s and trak-lok is holding up just fine.
the procharger is a great kit either for the singleport or newer splitport engines. the P1SC is also able to put out alot more boost if you change the pulley but the engine should be upgraded to handle the extra boost also.
all in all i`m more than satisfyied with my choice to procharge
