Now there are more options. Pettit is making a stage 3 kit which they expect to get near 400 whp.



Also, Mazsport has a Greddy kit with 350whp under 12 psi with their Intercepter which costs around $2000 (not including turbo).



There is a supercharger being worked on that has 2 gears. So, it comes on early and stays on throughout RPM. That is supposed to be 7-9k when it comes out, but it doesn't look like it will be out soon.

The greddy kit drops from the WG and the undersized turbine.



I have been seeing alot of reni motors coming for rebuilds.

i've done 5 greedy-powered renny's aready. it's more the emanage than the turbo itself though. the stock computer is just hard to work around.

After seeing the damage that occures to these engines I have decided that I will never boost one. If it goes poof everything is junk. The broken apex seals can't escape the engine and distroy everything. If I were to turbo an RX-8 it would get a FD engine transplant with a bunch cool toys and a good EMS.

guitarjunkie28

don't be scared. mazsport already has the interceptor out, and haltech's sure to follow.



or you could always use an fc or fd front cover and use whatever ems you want.

^ But you lose all the intake port tuning.



Wouldent you have to use the E11V2 seeing as there are 6 INJ's and 6coils?

guitarjunkie28

2 are rpm switches. the 6pi is the only thing you'd have to get around, but even then, you can still build a bracket, use the gear and solonoid from a power doorlock setup and actuate them.



the e11 wouldn't do anything much over the e8 besides the omp. it still can't control tertiary injection, as far as i know. and there are only 4 coils.



but if i were to get really crazy with a renny, it'd be a ported 4-port turbo motor. then other than the crank sensor, it's an rx7 motor, as far as the computer is concerned.

iceblue

I need to look into the E8 I forget about it I always think E6K.



Sorry for that over site on coils that was stupid lol :-P



Nice thinkin on that lock.

guitarjunkie28

i wonder if anyone would trade me a 4-port motor for my 6-port?



i'm curious to see how it would like some overlap. aka actuated peripheral ports.

iceblue

I have a 4 port but I don't know what it would take to put the 6 port in the car.



Obviously more because the ECUs are different and harness is different.
