Motor Swap Update Day One 8/1
I started the removal of the factory motor & trans lastnight. I started by doing a compression test on the factory motor, all cylinders were above 200psi with a difference of less than 10psi. Ive completly unhooked the wire harness from the factory motor (what a tedious freakin job), removed the battery and tray, upper CAI plumbing, disconnected the fuel lines, EVAP line, vacuum booster line, throttle & cruise cables and evacuated the AC. And transfered some parts to the new motor.
Tonight I'm going to some of the under car things and get the fluids out, etc.
My goal is to be ready to hoist by Saturday AM and ultimatly have the new motor running by Sunday night. With any luck its do-able, but with a project like this theirs always unforseen problems to over come. Sinewave has been kind enough to offer to help me Saturday and Sunday and he has lined up some of the speciality tools I need like the shop crane. THANKS KEITH YOU ARE THE MAN!!!
Wish us luck!!!
There are some pics on my home page too.

Some history on this...
As some of you may know in June of 2001 I purchased a used motor, transmission and Stillen/Vortech V1 Super Charger from Steve Sze of Carative in Philadelphia PA. Steve gave me a very good deal. The motor was constructed by IMPO Performance. IMPO verified what was done to the motor. It was bored 0.020" over. It has oversized stock pistons that have been coated for heat resistance. Shot peened factory rods and crank. The entire rotating assembly was dynamically balanced. The fuel injectors were also cleaned and balanced by IMPO. The heads are stock but with a fresh valve job.
IMPO claims that this motor will take 6psi of boost and a 125hp Pro-Fogger shot of nitrous with a few degrees of ignition timing retard. So IMPO thinks this motor hold ~400 hp at the crank, we shall see! My approach will be more boost and less nitrous. I've installed the 3.25" upgrade pulley from Vortech which should be good for ~10spi. I cant make up my mind which way to go with the nitrous, dry or wet. But with boosting at 10psi I don't think more than a 75hp shot is needed, its really just an intercooler in a bottle. Yes I know I'm pushing the motor and could very well blow it up, but that's half the fun and I've still got my stock motor to fall back on.
The transmission I got from Steve has a lighted factory flywheel and a Centerforce Dual Friction clutch upgrade. So I think its up for some abuse too. Just as with the motor, I've got my stock transmission to fall back on.
IMPO recommends that the motor be broken in for 2500 miles before I do any sever duty racing. According to Steve the motor had only ~600 when he totaled his Maxima, IMPO verified this too. So by October or so I should be ready for the track. I'm hopping for mid to low 12 second ET's, that may be a bit optimistic but you got to have goals!!!

Oh yea!!! Im gonna run dino oil till 2500 miles (IMPO's recomendation). I plan on changing it at least three times. Perhaps after the first 25 miles or so because of fears of build contaminants and dirt from shipping etc., then after 500 more miles and then again after another 1400 to synthetic.
