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

The photo uploader works on mobile

I tore down the car from its previous setup in mid January to start the current build. The engine was built over a year ago and has been running around on 240-280whp for the past year or so.

Won't work for me... when I click on from device it won't allow me to select my gallery to pull pics from...

Glad to see that you're keeping up with this

35-40 lbs of boost through a 6266? I see a few issues here with this. 1- what head studs are in the motor? 2- Depending on what in tank pump that is, i seriously doubt a single in tank pump is going to supply enough fuel for you to achieve the power that comes along with 350-40psi through that turbo. I personally ran a PTE6265 @ ~40psi on a 2.3L DISI motor and made north of 700awhp. I ran 4 2000cc injectors (after maxing out the 1000cc injectors) in addition to the 4 DI injectors for a total of 8 injectors with two in tank DW300 pumps. As others have already said that T2 trans is not going to last long in the slightest at the power you are aiming for.

All in all the direction this is going excites me. :)

ID1700x injectors and a 400+lph pump, 8an feed with a 6 an return, plenty of fuel

ARP head studs and a cometic HG are on the car, this much boost on this motor isn't that uncommon.... Well it is in the small minded community of the Mazda Miata

Run equal feed and return. A smaller return can cause pressure fluctuations at idle because you are using so little of the fuel.

Good luck with the build. That much power will be cool.

it's small minded because the amount of people making big boy power can be counted on 2 hands. Because most don't need it and the rest never actually get there.

But yeah, this is exciting and I'm genuinely excited to see it when done.

Our transmissions are the fuse that keeps the load on the circuit below a certain threshold.

Once I made over 400whp on my miata, my dick got smaller. So there's that...

still in for Precision goodness

Did you get a tracking number from Briggs? I still haven't got mine. Mentioned I would have a tracking number on Saturday.

I provided him with shipping labels this morning. My guess is he got busy finishing my stuff sat. I bet you have tracking shortly today.

Hopefully. The lack of upfront communication is a Lil irritating.

one day shipping from him to me

why w/a? quarter mile car?

I believe he's going for a half mile car.

3 honk ricer racing.

cant hear honking with a wastegate screaming... Usually someone hanging out a window screaming and waving his arm 😂

But yes, half mile events and I have a few buddies that have access to an air strip from time to time.

Does your ECU do rolling antilag?

It does, that and traction control and I have added 4 egt sensors and a few other things. I have used about every option the MSPNPro has, E content sensor too.

Nice. The "pit lane limiter" on ms3 is great. Hold the button and it cuts spark and builds boost lol. I've been itching to dick around with it.

Ive used the pit lane limiter a few times. Im going to try to get the actual rolling launch control going if not the pit lane limiter does work decent haha.

Ever wondered what its like to get spark cut with the clutch engaged at full throttle at 60mph haha? The car bucks lmao

cool build.

not entirely different than my own build... keep in mind its not a Miata lol.

So then the logical follow up: why not air to air?

Logical response to your logical follow up: why not w/a, because i want it, because its cool, because aerodynamics plays a huge roll in hitting speeds in the 1/2 mile, less air in the front bumper the better

ahhhh, that's right, you're probably going to seal off the whole front end for drag.

k I get it now

800hp turbo on 400hp parts.
Curious what your budget is?

Subscribing for the carnage!

Haha, I totally hadn't thought about this either and was purdy confused...

Can't wait to see this build and car in action.

Only "400hp part" in this build (and this is according to mt.net) is the transmission

small update, few more cool parts in, and everything fits!

Cool stuff.

This looks like a party. Love the water to air cooler, so nice and tidy in the engine bay.

Are you going to be building cranes/support braces for all that stuff btw?

I had a similar thought, especially with all the water in there. Otherwise only the 2 manifolds would be ​supporting the weight. And that's a long manifold, I guess if it's sch80 stuff tho?

He must have some cool supports in mind, can't wait to see what they are.
Lots of cool stuff there.

Maybe it won't matter in the 20 odd seconds it takes to finish the 1/2?

There will be a support on the under side of the intercooler probably bolted to the block where the AC bracket used to be and curved around to support the bottom. It will probably be made of 1/2 steel rod.

A crane of sorts is also in the works for the turbo but a lot of fab guys have told me its not necessary. As long as there is a GOOD flex section in the downpipe not far after the turbo.

The car will be driven on the street way more than on the 1/2 mile strip.

Fab guy checking in.
Weld a standoff to the turbine housing and brace it to the engine block. Cranes don't do much. All OEM turbo systems I have seen bolt the turbine housing to the block and OEM's don't do what they don't have to. FWIW, the guys that do the Alpha turbo kits for Nissan GTR (T1?) spent the time to have CNC braces milled that use the turbine housing bolts to brace to the engine block...

I would definitely consider bracing in the method that the oem/high end guys use.

Ever considered that its done that way OEM because its cheaper?
