I'm about to take the plunge into making a 93 Rx7 a 375HP to 450HP car. I have about 12 grand saved up but since i have never built on a rotary before, I have some questions.
1: What can new iron seals handle?
2: Are Ceramics worth the extra money?
3: Any tips for tuning the engine.
4: BNR stage 3's vs. single turbo upgrade.
5: any other possible tips to keep me from blowing up the engine

.
Thanks for all the help and the people on this forum are a lot more forgiving than others. Thanks.
