so i take it that the best way to be a daily driven 350+ street demon is to do a TII conversion and upgrade: seals, turbo, fuel system, tranny, diff, etc...

but if i wanted to race i could put in high comp rotors... maybe when i when the lottery

Many people have had great success with the 9.0 rotors. I've heard of people running the 9.7 rotors, but those are people who are VERY good at tuning.

that's some dream Okie. what about fuel management (new pump fpr and stuph and maybe some bigger coil packs i know that the rx-7 packs ae already good but you can always go bigger

hmmm. for fuel managment check my sig. I already have a big enough pump. The Haltech could take care of delivery along with the 1600 secondaries. FPR is a good idea, but implied. I plan on getting one for my 13BT. Of course, then you have stainless braided lines and and MSD6 ignition boxes. But like I said, that is just my dream "engine".

now that I think of it, a 20B conversion would probably be cheaper.

maybe you could use 9.2:1 rotors from an 84-85 13b, they are factory 3mm seals. the only downside is the rotor wieght, its like 12lbs vs 9.5? for the s4 and 9 for the s5,s6,s7,s8.
