I want 400 rwhp whats the best way to get there?
 

I have a 93 rx7. I need to rebuild my motor. I was planning on having rx7store.net do the rebuild with street port. My motor alond with the turbos have 125,000 miles right now. I was wondering what the best setup would be to reach 375-400 rwhp with reliability. I have heard that you can reach that on stock turbos(but wouldn't a single turbo upgrade be more reliable?) well any thoughts would be helpfull. I plan on do all the work except for the actual rebuild and tuning. Please give me some ideas thanks

Street port motor,PFC,FMIC or SMIC,Full exhaust,Twinpower, and this turbo

Goodluck!

Forgot you will need a good clutch.

so i wouldn't need to upgrade the fuel system?

I knew I forgot something, yes you'll need to 550cc to 1600cc or 850cc to 1300cc, etc also a supra FP too.

Which place would you reccomend for me to have my block rebuilt? aspec tuning or rx7store.net? there both in driving distance to me.

Pm'ed you
