So my car has been down for 5 1/2 years. Just had the motor freshened up. Not much has changed except new pistons, .030 bore,rebuilt stock heads and cams. Old specs in sig. Car had a P1 Procharger on it with a 3.2" RR pulley. Not sure of the compression but the old pistons were cp-s9822 and i now have Manley 594130C
I purchased a D1 with a 3.4 8 rib before the car broke. Both head units needs rebuilding. They both are disassembled, and will be rebuilt by yours truly. Prev owner stated a little over 500 hp/tq. I saw 478hp/450tq but that was with #8 cyl having issues.
I will be switching over to the 8 rib setup when my timing cover and valve covers get back from powder coating. My question for you guys is can I install the D-1 with the slightly larger pulley without issues from my current tune. My plan is to install the D-1, go 500 miles on break-in oil, another 1000-1500 on dino oil before switching to full syn and taking for a tune. Im trying to only have to put one blower on once as long as its safe to do so with D1. I dont see a issue as I wont be getting into boost that much before a retune.
My options are:
1. Put on P1 with 3.2 6 rib, maybe still change others to 8
2. P1 with 8 rib 3.4
3. D1 with 3.4 8 rib
Thoughts??
