Super 70 andmy newFC3s

I recently purchased a T3/ Super T70 turbo and an FC turbo 2, the car is in great condition with the exeption of one little apex seal. The turbois brand new. I a new manifold on the way but have a few questions about a few other things.

My plans for the 7 are mainly as a second fun to have kinda car. I will probably end updraggin a little and it might see a drift track too. I planon doing someminor port work when the engine is apart so that shouldhelp a little also. I am not new to mechanics,just FC's.

I am going to have to replace the apex seals anyway so shoud i go ahead with a full rebuild?

I just recieved the exaust manifold and need to order an external gate, but am a little unsure ofwhat spring pressure to order. i want 450 to 500 from the wankle when im done.

My Fuel pump is done but what injectors are the best?

Where can I find a datalogging and fuel programing computer for the little rotary?

That should be about it.

SSautochrome turbo kit? I would go with a much large frame t4 with a decent size a/r for 500rwhp..

Yes do a full rebuild.

I would start with a 1 bar spring, and use an electronic boost controller to raise it from there.

Depending on what fuel pressure, you might be able to get away with 550cc primares, and 1680cc secondaries. However 720/1680 might be a better selection. I don't know I don't run the common 4 injector combos.

So which pump do you have?
Haltech/Microtech/Fast/Motec/AEM/EFI etc for the efi..

im going with haltech for the controller and the pump i thought i found until i called rp on it. The best pump that i have found has been the Rotary performance pump, but im wondering if it is going to put out enough fuel...

and i might not get 500 but anything over 4 is good enough for me.

T3 turbine is too small for the 13B.

Just saying you want X power is good but it is only part of it. What type of driving will the car see? I can easily say just put X turbo on for 500hp and be done with it. Or you can figure where most of your driving will be and then go from there. From what I've read here. You want two conflicting things 500hp and drift car. A 500hp rotary drift car is not needed. 330hp would do the trick and spool would be instant with a properly sized turbo. 500hp rotary while done right can spool nice, it wont give the ideal power curve needed for drifting.

like i said... i just want a fun car again. i used to be a dsm guy.

it might see a drift track
might see a drag or two

i just pulled 500 out of the sky really... im new two rx7's, my old mitsu had 530 before i got tired of tuning.... but it was a better turbo... and a few other things were top notch, but thats beside the fact...

Well if fun is all you want, what you have will work for fun. If bigger power is what you want you may want to think of stepping up to a T4.

I have heard many people get good results from the GT35R and it has a T3 turbine.
