Only time will tell....Turbo II 6266 getrag etc. etc....TIME HAS TOLD: FAILURE
 

Whats up guys... long time lurker short time owner, shorter time builder.... I tore the car apart early January 2017 and so far this is what has happened... time for a picture dump... this is just what I have on my computer as I get bored from time to time I will add more....

Basics are, 10.5:1 Wisecos, Manley Rods, stock MSM head, B18 intake manifold, briggsmotorsports custom manifold, MSPNPPro, PTE 6266, ID1700x's, VP X98 fuel, TurboII trans, getrag rear end...


Let me know if you have any questions I guess haha

Sub'd. Looks epic.

Those ID1700x :eek5:

They are, planning to push some X98 through them

Only something like this could come from an area surrounded by NASCAR... ;)

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

speaking from experience or have any proof by chance?

Both actually.

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.

Dann

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

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.

sorry, guys... I didn't leave because of anything on here, in fact I welcomed the advise... but any who... its a pain in the ass to get pics from my phone to a computer and onto here... want updates? go look at fb
