13B-RX3

iTrader: (2)

I am building a 73 rx3. The chassis consist of a chassis engeneering 3/4 tube frame,28 12.5 et street,8.750 crysler 4.86 rear end. When i set out to build this car i didn't ever want to have to upgrade the chassis after the original build. I wanted it to take any amount of horsepower i could give it. I have a 93 13B-REW that is bone stock, aside fron some intake manifold mods, and i am wondering what the potental of the engine would be in stock form. I plan on running the car this summer at low boost levels and going trough the motor next winter.I would like to do a port job and upgrade the apex seals.
i plan on running a haltech e6k. I have'nt chose a turbo yet but that will be the next purchase. I am not above learning from others mistakes so any advise would be greatly valued.

I guess i would get more response if i asked the question differentley. The engine that i am going to use is a MFR with about 20000 miles on it. As i start to increase the power what is going to give me problems first? Assuming that there is no detonation. what would it take to make 650 rwhp and have the motor stay together fot at least one season of racing.

Does the 13B-REW need to be dowled? I was under the impression that they could take the power without it. And are you are also saying that it cant be done with 2mm apex seals?
