Both runners open to the wastegate.
The earlier manifolds did not have this cut in them. ~Mike............. |

Did you have to cut off the air pump mount to make the 90 deg elbow fit or did you remove it for another reason?

Your set-up looks remarkably similar to mine minus the to4r. Same intercooler & radiator set-up at least... I thought I was the only one. AND!!! your in NC. whats going on here? We should meet up some time.

Is there an update on this yet? Looking for dyno numbers...

Well I sold that RX-7 in the end of July. Dyno'd it at the end of June. I had rebuilt the motor, no porting. It initially made like 349 whp and 259 lb-tq on the old motor and the new motor it made 365 whp and 307 lb-ft torque, both times at 14-14.5 psi. Although the dyno started to make peak power and die down a little around 6900 rpm and i was revving easily to 8200 rpm daily. The .84 A/R turbine Housing was a bad choice, should have gone with the .96 A/R and I wouldn't doubt making more power. Since I in school up here at Raleigh, I don't have access to my dyno charts back in Hickory. I basically rebuilt the motor as my final project before I sold the car to start a new project. Picked myself up a 2003 Nissan 350Z Performance and it should be Twin Turbo by the new year and then many things after that.
Tookwik; I see that you go to State as well. I'd like to see your car sometime. I remember looking at your HKS Intercooler install thread a while back and realized alot of yourstuff looked similar to mine. And if you ever want an extra hand when installing stuff or just working on your car in general, just let me know. I miss working on my FD. -M-P |
