Get rid of the Turbo II transmission as soon as you can. It won't hold up long above 500whp or so.

Care to share? what would you recommend in place of the Turbo II... there are RX's making more than 550 on the stock trans lol

An RX-7 at 550whp will probably have around 330tq or something like that. A Miata will make 420-440tq at the same power level, and will snap the input shaft.

Ps. I've seen the same failure on RX-7s at ~450whp, when driven hard.

looks like the start of an awesome build.

Do you anticipate a packaging issue which is forcing you to go water-air on the intercooler?

Almost the opposite haha, I am running into packaging issues because of the water-air intercooler, I did it to help the high compression as well as help with the long pulls the car will be doing

I plan to hit a few 1/2 mile events this year

Nice,, this is exactly what i wanted to see someone doing - What are your power goals?

If the TII won't hold up - what's the solution for that? All reasons why i didnt want to do this.

Your compression is much lower than I would have gone for your fuel and head. You will have no need for anything more than a FMIC.

I don't have a solution, I plan to keep timing low and keep torque as low as possible, maybe it will hold maybe it wont.

The engine was built a year ago in Colorado and built for E85, X98 is more readily available to me than E85 right now so that is why that fuel is being used. As for the A/W that may be so but 35-40 lbs of boost for long pulls, I will do all I can to keep temps down

Default Waiting for the outcome.

Really looking forward to seeing this finished.
It's been a long haul, has it not?

I think I saw a thread on facebook about this build. I have a feeling that Forrest (and reverant) scared him away from Miataturbo.

Ill 2nd this, I'm new to the miata scene but I've owned rotary's for the past 11 years my last being capable of 300rwkw but broke 2 gearboxes (s4 turbo I, then s5 turbo II which have a thicker and extra ribbed housing) so i DE-tuned. they are only good for 500hp MAX and 350-400Ftlb but not for long sustained use, Rx3's weigh around 800kg mark and originally used them alot in drag racing but they are just too weak , generally swapped out for w58, R154 or t56 boxes, then the more expensive TKO500/600 then g force or liberty.

Miata's have more torque with having more rotating mass @ similar rpm 8600,@600hp = 380ish torque, anyway looks like an interesting build.

Yeah, I was looking forward to following this build. Bummer the OP stopped posting when folks offered advice and criticism from experience...

The Facebook rant was pretty funny.
