and here we go...

Picked it up a couple years with a blown motor that was taken out and no idea what i was getting into.

https://www.miataturbo.net/attachmen...ine=1383292354

Since I hadn't had experience on building a car or anything like the car just sat while I built motivation to do something with it.

So one day a beat up Miata came along at a salvage auction with another 1.6

which was motivation enough to start dicking around with it

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

I didn't have an engine crane at the time so we just used what we had, lol.

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

Since I had it I figured might as well do a few things.

So I took the power steering pump and brackets off.

Took the clutch off to take a look at it

https://www.miataturbo.net/attachmen...ine=1383292354

Which didn't look that great.

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

So I replaced that clutch with a
-fidanza lightweight flywheel
-exedy disc
-center force pressure plate

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

After that i threw on the td04 turbo/etd shorty manifold that came with the car.

https://www.miataturbo.net/attachmen...ine=1383292354

time to stuff it in..

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

Hurray.

https://www.miataturbo.net/attachmen...ine=1383292354


Now it was time to throw on the turbo and the IC piping that was custom made by some exhaust shop from the previous owner, very inefficient

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

Tied up little odds and ends's added cold wrap on the coldside and mounted Tanabe strut tower brace.

https://www.miataturbo.net/attachmen...ine=1383292354


https://www.miataturbo.net/attachmen...ine=1383292354

picked up a mishimoto aluminum rad

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354


https://www.miataturbo.net/attachmen...ine=1383292354

exhaust junk

Threw that on as a test fit.

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

made my first (probably last) downpipe

https://www.miataturbo.net/attachmen...ine=1383292354



https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

Made sure that it fit on the car and moved on
https://www.miataturbo.net/attachmen...ine=1383292354

Picked up a perrin foam filter but needed and adapter plate to fit on the MAF so quickly made one with 3inch exhaust pipe hah.

https://www.miataturbo.net/attachmen...ine=1383292354


https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

Hurray, valve cover was pissing out oil like crazy so had to replace that

https://www.miataturbo.net/attachmen...ine=1383292354

https://www.miataturbo.net/attachmen...ine=1383292354

Checked the plugs and they were disgusting so I changed those too and added MSD 8.5 high conductance wires

https://www.miataturbo.net/attachmen...ine=1383292354

Also went with a bit colder plugs

https://www.miataturbo.net/attachmen...ine=1383292354

Poorly polished the valve cover poorly and cut the timing belt cover off

https://www.miataturbo.net/attachmen...ine=1383292354

yada yada this is how it sat in 2012

since then i've pulled the motor and did a few seals then popped it back in.

but i will update a bit later.

Started dicking around with quarter panel stuff for the rear overs



Attachment 99733

Never tried cutting and welding fenders, but eventually turned out alright. Not like anyone will see it anyways. But just need to seal off the bare steel/ paint it.

Also fitted the Fenders.

Sean 01-14-2014 11:21 AM

Not too bad of a build so far what type of management are you using and what fenders/flares do you have?

curly 01-14-2014 02:27 PM

Looks like a dirty bastard, love it.

And yeah, what management? It's either not MS and you need one, or it is MS and you need to get rid of the AFM post haste.

turbofan 01-14-2014 02:44 PM

Well, he said "no tune" before. So does that mean stock injectors, no RRFPR or acu or anything?

If that's the case, it's a wonder it survived the dyno session.

ScottyP3821 01-14-2014 02:50 PM

Get a MS and clock that turdbo and you could get rid of that chunk of intercooler piping.

Bought MS3 from Rev a little while ago, just screwing around with other stuff right now, havent gotten to wiring it up yet!

and for fenders i went with Autokonexion 40mm fenders from the GT kit and the new 30mm ones they just made.. will post pics soon.

wasnt expecting to make squat for power then ended up with pretty decent numbers. although i always monitored the AFR's was still pretty alright.. maybe the dyno reads a bit high.

But for management all it had was the Vortech FMU, you can hear it ping like a bastard on the dyno but hopefully i didnt do too much damage.

Ended clocking the turbo and making the IC piping a little more efficient as well.

adopted the relocation kitSo I could use my stock and AEM sensor Oil pressure stuffs

https://www.miataturbo.net/attachmen...ine=1389746380

Stock on the right and AEM on the left haha.

https://www.miataturbo.net/attachmen...ine=1389746380

-throw out bearing

https://www.miataturbo.net/attachmen...ine=1389746380

MS3 also came in, getting ready to party

ScottyP3821 01-15-2014 09:23 AM

Awesome progress man! That FP looks pretty serious though. Im surprised you didnt just replace it with a stock pump. Should be more than enough.

Yeah might be a bit excessive. Got it pretty cheap locally. Hoping that the aeromotive fpr will keep it in check. Can always sell it if it's too much

Sean 01-15-2014 02:20 PM

Fuel pump should be great. I am a big fan of too much pump rather than not enough. The aeromotive FPR is an awesome unit and should control your pressure just fine. Great progress and I cant wait to see how this thing turns out.

My thoughts exactly! Hopefully it works out in my favor

Finished up the exhaust, not that pretty but whatever. Crush bent 3in that came with the car

Attachment 109137



Attachment 109138

Also cut these out and switched to v-band clamps (never going back lol)

Attachment 109139


Basically have the motor in and running and all that.

Ended up getting a wobbly crank, and found out it was from a used cog I had got from when I accidentally dropped mine and it had chipped lol...bah

Attachment 109140



Attachment 109141

this was probably why.. haha going to order a new one this week hopefully... along with some cam seals and front crank looks like it started leaking too... for whatever reason... maybe the cam seals need rtv

Excuse my welding, never been good at it, and with the metal being so thin and trying not to wrap it didn't help.

another small update:

Finished up with my exhaust stuff:

Attachment 239175

hated the fitment of old one i made, was basically rubbing on the front sub frame, and was a nightmare to bolt back on.

Attachment 239176

was using this collector flange initially

Attachment 239177

and switched it out for some ebay v-band flanges

Attachment 239178

exhaust is just a crush bent 3in (cause cheap) and basically 2.5 in DP

then i wrapped it up, cause it looks pretty now

https://www.miataturbo.net/attachmen...ine=1404069134



started rebuilding my front end a bit.

did:

-ball joints (upper/lower)
-tie rod end
-poly bushings in the UCA/LCA
-ARP extended studs

Attachment 239179

along with throwing on the wildwood kit i had bought from a member on here:

https://www.miataturbo.net/attachmen...ine=1404069134

I think the novelty wears off when you run out of funds and creativity.... Or it breaks/runs out of gas

Few new things:

Bought a 96+ Miata diff via ebay for a good price and driveshaft/axles from some other dude.


https://www.miataturbo.net/attachmen...ine=1406558256

Seeing as they had just cut the stub shafts off and he wasn't really sure whether it had a Torsen or not I wasn't too thrilled about grabbing it but for the price (about the same price as a typical 94+ open diff) I went for it anyways,

With some help got the stub shafts out and cracked it open

https://www.miataturbo.net/attachmen...ine=1406558256

Thankfully it contained a Torsen in hopefully good condition.

Couldn't break the 25 year old axle nuts free that night but I'll take another crack at it this week and throw it together.
