2JZ Miata 68mm turbo six speed
 

So I have been working on this for a couple months maybe one day a week when I have time. I have kept a pretty active build thread on the supra forums but I thought I'd share some pictures and info here for fun.
Major parts are
2jz gte vvti motor
Cast manifold
Bullseye 68mm turbo (good for 900+whp on e85 with the current turbine wheel/housing)
1000cc injectors we are going to start on pump gas
6 speed transmission from a 350z
Spec twin disk good for 900ft lbs
Pro efi 128 ecu

Im surprised i have not gotten more negative post cats for this build thread yet.

custom intercooler i had made to a solidworks drawing. Fitting a large core is difficult even more so with a longer motor so this is what we have to work with. It is a bell intercooler core. Everything will be vband and vanjen clamps i hate intercooler couplers.

In for this build!! i give you positive cats sir!

That's awesome, care to link your build thread?

wow, is that a subaru bumper in the background?

haha thank you sir :D
It is on supraforums but i dont want to link it and get in trouble. Anything i work get done moving forward i will be posted on here and there though :).

Yeah i had a GR sti that i attempted to daily drive when ever it was running before pulling apart the miata for the 2jz swap. I ended up selling it and buying a new prius :rofl:.

Here is some videos of that dump lol. My goal was the first GR sti in the 10s..but instead if bent a rod bolt or two on a turbo tuff i beam and then i ended up just putting a smaller 58mm turbo in and a lighter built motor until i sold it 400whp was boring :giggle:.

I got the ecu half way mounted tonight. I still need to head to the store to get some scrap steel to make a little bracket for the hole on the left. Its so hard to fit all these super sized items in this little car it calls for mounting things in some odd places.

If you get this setup to work it will be nuts.

Nothing wrong with that :likecat:

No need for neg props either, you're using good parts and shooting for absurd power

Absurd power is really amusing

Thanks for posting, interested to see where this goes. What are your plans for the car? I'd imagine that thing is going to be quite a handful to drive.

I'm seeing more and more swaps on different cars run the tree fiddy trans
they're getting popular. will likely go up in price soon

Plans are for it to just be a fun car to drive. My only real goal would be to make a 9 second pass eventually when we can actually get it running and kinks worked out.

350z trans seem pretty solid from my research and are perfect for many swaps. A big negative though is there massive size fitting it in the miata was well interesting and we still have not 100% bolted it up only shoved it up and down in the tunnel and then correcting the spots that hit until we stopped hitting. I think i only paid around $700 shipped for the trans and there are people making 1000+whp on them without issues in heavier cars.

Someone should make a setup to use one on a BP it is cheap and would be a good replacement for the current 6 speed swaps even though they are pnp.

What are you running for a rear end?

It is only a ford monster Miata 7.5 setup I found one locally for super cheap and only have about 5-600 into the whole rear setup by the time I sold my stock rear end.

Once it explodes on what I'm sure will be the first time I launch it I'll move up to the 8.8 I actually wanted.

That's an impressive swap! I'm curious to see how it all turns out.

Motor can go back in with the trans once we get the pilot bearing i ordered. I did not like the bushing setup that came with the swap kit. I also got the valve covers cleaned up and some -10an fittings welded on.

Some more parts came in.
Can gauge for the pro efi

Also ordered one of the real street catch cans so hopefully we will have that this week.

Oh damn. Straight six Toyota engines are my jam.
I tried my best to break a 7.5 behind a 350 whp 302 and I just ended up breaking the c4 trans... after 10 years of constant abuse.
Any more pics of the dif mounted to the rear subframe?

Interested in watching this come along, keep the pics coming.

why the vertical runners?

reading an outdated Maximum Boost?

maximum boost was outdated when it came out

lol....
All i did was find out my maximum size i could fit, then draw up a model in solidworks with how i wanted end tanks and the 90 degree vband end for adjustment on it then sent it to a shop called fathouse fabrications and then a couple weeks later my intercooler showed up. I did not choose the core or any details around it, it a quality bell ic core though.

Some jankyness..the switch is for the fuel pump we just put in.

https://www.miataturbo.net/attachmen...ine=1458565894

taking a look at this picture i need to adjust the catch can a tiny bit to straighten the filter out easy fix though

https://www.miataturbo.net/attachmen...ine=1460035048


Almost done

that was quick. looks mean.

going to shroud that tiny radiator?

No plans to as of right now. Once it is running i will be able to figure out if it can stay cool enough as long as i stay away from traffic (rare around me) most speed limits are 55 ect. If there is a issue i will take it from there. Evos run this radiator often and claim to have no issues in traffic even so im hopping I can experience the same even if I have to avoid somethings. What i really need is some kind of ghetto cowl hood made or modified but i have no clue how to go about that so ill just ignore it for a little bit.

Will you have to clearance a hood to fit things as is or is a stock hood going to fit? If a stock hood fits the singular vents are going to be your most efficient option in terms of heat extraction.

Looks good.

Sadly the stock hood will not fit without alot of holes cut in it this motor is fairly tall and the tall turbo/radiator/throttle body is not helping.

I cannot find any aftermarket options either. I am open to a ghetto ricer looking hood if it fits but i cannot even find that.

I may start hacking up my hood one hole at a time though just to see how close it is. By the end the other 2jz miata guy got away with only one hole in the hood for the front of the valve cover but my stuff all sits taller.

I like the oil feed restrictor.

I can only assume your making fun of the shitty eBay oil feed line that kinked when it was tightened because it was to cheap to spin like it should have been doing.


I figure if it leaks I'll make a new line at home.
If not then I'll run it turbo has a restrictor on it anyways so the -4 line is pretty overkill.

Well hopefully will be able to start it this weekend or so just waiting on my tuner to have some spare time.

I approve of using large turbo on a miata. Looks awesome man!

Turbo is on the wrong side man.

Are the skinny's just rollers? Or is this a drag fag?

The toojay is a heavy lump. I wouldn't expect him to corner well with it. It will probably be a straight line car.

those are my old winter tires but they are not overly skinny very similar to the size tire i will be running when the car is driven.

But no the car will not be driven around the track nor will it be on turny back roads driven aggressively. The car has no purpose other then it was fun to build and hopefully will be fun to drive. It just was not what i wanted at the time and nothing is stopping me from buying another miata or a s2000 ect should i ever want it again.

This turbo is the same size ish as yours
I'm excited to see how this turbo does on this motor.

Actually got to set it on the ground today after tightening up the suspension bolts ... car obviously needs an alignment very very bad and will most likely will be put on a trailer to have it done when the time comes.

Car needs some new springs and tires in the front but im unsure what ones i will go with if anyone has any suggestions car has koni yellow shocks that were on the car when i bought it.

Dat ass!

That's fucking awesome!

Will you need to cut the rear wheel wells? I'm guessing you'll have a lot of squat!

I think its in heat.

Are you going to pull the rears?

I will work on that stuff little by little

First step for the rears will be having them rolled
then ill go get an alignment
From there if it rubs (which it will) i will figure it out.

I may end up eventually just finding some stance fag around me that wants to make a couple monies to bolt on some flares and cut the fender back. Im not into doing that kind of stuff.

I am still trying to wrap my head around what suspension setup i should go with for not only keeping the front end up but to get some traction.

The current koni yellows are old and worn out im sure.

Im open to suggestions..and id prefer to stay away from coilovers.

why do you prefer to stay away from coilovers?

A couple childish stupid reasons.
I do not care to lower ride height.
I also know i am far to cheap to buy very high quality coilovers which leaves me cheap ones I had BC coilovers on my old sti I did not enjoy them at all granted i did daily drive the car.

A solid strut spring combo is what I want in my head. Unless there is a very very big benefit of going with xxx coilovers then of course i would consider it.

it really depends.
this doesnt look like it will be a daily driver
and it certainly won't be a twisties carver or road racer
so the only thing left is highway pulls or something

I'd suggest the "budget bilstein" setup, but technically it's a "coilover"

if this thing hooks like it should, it will squat like crazy, and you'll need to be able to raise ride height if needed

.........there are only 1 set of springs for these cars that are not utter junk. FM

I will look into budget bilsteins right now.

flame suit on, and im drunk

Vmaxxes arnt bad, a step above ricelands, and not too expensive. lifetime warranty (i think). For what you are doing, I think theyll suffice.

Good suspension will help with traction. All about weight transfer.

If you had a subaru, I could point you to a drag specific suspension, with lateral links from a different car.... but sadly i don't know anything about a miata drag suspension...

All I know, is you want to maintain as close to zero toe and camber throughout the rear suspension travel, and have enough squat to minimize hop, but not too much, or your launches and 60 foot suffers.

maybe have slightly positive camber at rest?

Yeap. I'm running mostly stock suspension and very sticky tires, 1.74 60'. About the fastest you'll find any miata running that's not spraying out of the hole, faster than some V8 miatas out of the hole.

Operation 1.5-1.6s just to set the new standard ;)

Nice.
I had a cracked subframe on those times (now fixed) and ran a better 60' the last time I broke an axle but didn't get the slip. That's a trailered race car in the left lane for reference.

Well had some starting issues i think my current oem harness is just to beat up many clips broken many places where i hacked in and was unhappy. So tore it back apart and ordered a new harness that will have only the connections i need. It will also have a "mill spec" connector to the firewall so i am excited to play with the fancy connector.

Since i was getting a upgraded harness i decided it was also the correct time to switch from a janky oem 3 coilpack wasted spark setup with an ignitor to a aem smart coil setup.

There is a company that makes a bracket but wants $250 and it does not fit right with the VVTI head so i decided that I will design up my own and give it a shot first before resorting to paying that much for the bracket.
Here is where i am currently with it after 1-2 hours of playing with it unsure how happy i am with it yet.

Well i hope my measuring skills were not that far off but its easy to fix at least :).

Yay for poorly made homemade/designed parts.

https://www.miataturbo.net/attachmen...ine=1462623020

Just sent out my cluster to Revlimiter so a surprise is in order. It will either look really good or really ghetto so im excited to see it :D.

If Adam's gauges look tacky, it's because you chose a terrible design.
His work is very nice.

We worked on a custom design with an idea I had. He does good work im sure but I ment that you never really know what it will look like till it is actually assembled and in your hands.

Well like i said you will either hate it or tolerate it but i am happy :). (ignore the missing needles car has to be running to put them in)

"TRD"

lol

It is modeled after the supra Trd cluster which has been for a long time my favorite cluster.

Brilliant. I am really tempted to get a Honda or MG badged horn button for my Momo just to confuse people.

Man this build is very cool! I'm really interested to know what kind of number this thing will push out. I support you in this thing man keep it going! 😁

Buuuuump

Where's the update that includes the video of the car running? Still waiting on the new engine harness? It feels like this car has been sitting/not running for at least a year already...
