Well after looking at the forum you gave me, i was wondering....if i decide on the d1 over the p1 am i not losing some perfomance? Apparently the d1 takes longer to spool up? The p1 is rated over 650hp, but it would push that blower to the limit, the d1 is more powerful, but you lose drivability with it.....Ah man this is getting nuts.....

I have been through 2 cars....350z tt and 300zx tt....i loved both cars to death and hated selling them. I hated the problems i got with trying to push the cars. In the end i realized that i just loved driving the cars....i want a great driving car that sounds wonderful but has a mean punch to it. thats why i am thinking 500-550 rwhp would be really nice, i know i will never be the fastest...but the faster you go the more stuff breaks....at 500rwhp i think i can do it with a p1sc, exhaust, headers. I then have the option of going over by doing a H/C package on top of the S/C. Now i would be over 550rwhp. If my motor blew then i could get a forged short block and add some spray.......I just dont want to risk losing drivability with the d1sc....let me know if what you think?
