Pros:
93 car with torsen and 1.8 engine, new tires, MazdaSpeed Miata seats and hardtop for $2000
ARTech exhaust, Reverant MS2

Cons: 4.10 gears with 5 speed trans. Wrecked front end, body not in the best shape, headlights didn't line up, not many enough to make it a track car.

My suggestions is 94-00 with torsen, 6 speed if you buy a NB, clean car you can actually work with. Don't "make it work" like I did with my car, you'll regret it and want a new car like I do.

AGXs are terrible in every single context. You should never, ever buy them.

It sounds like Hustler regrets getting the Begi reroute spacer, I think he had a bunch of trouble with it. He recommends the M-tuned one furiously...

I had problems with begi reroute but they fixed it and made things right. It's just a bitch to remove or install

I regret just about everything I've done.

*Bought a rotten chassis that wasn't cared for
*Neglected the car during down time escalating body deterioration
*Bought an OEM replacement plastic radiator instead of larger Aluminum
*MS1
*Supercharger
*Didn't roll my fenders when I had access to the tool
*Bought a $150 six-speed transmission
*Decided to build my own turbo manifold / dp instead of buying AbsurdFlow
*Wasted a bunch of money attempting to "re-invent the wheel" with reroute
*Didn't use silicone sealant on BEGi coolant reroute

This is all helpful stuff. What about the opposite, some areas where you can skimp out?

Few more things i regret:

Heavy 16" wheels from a honda buddy. They look okay i guess, but bad move on my part. Will be getting some new light 15x8 konigs soon enough.

550cc ancient rx7 injectors. I dont know how much i "regret" these, because i just bought some dw800's and have not installed them yet. From what i've read though it's probably worth it to go straight to a quality injector.


Areas I've skimped and don't regret it:

MS1/MSPNP. It was brand new when I bought it in 08 or so, the mspnp had just came out. Honestly i don't regret this, it's been a great ecu for me thus far and I'm going to continue using it until i see the need for something better.

Ebay FMIC. Works great, cost nothing.

Ebay Radiator. I didn't even get a "godspeed" or "mishimoto". I went as generic as possible, iirc around 100 shipped. It's exactly the same radiator as a godspeed or mishimoto.

Greddy turbo kit. Got it for cheap, worked well when i upgraded it, made lots of powah, no regrets for a 1.6 setup.

Ground control/kyb setup. Most people will tell you they are complete ****. This is probably true, but I still rather enjoy my setup despite what the internet tells me to think. I'd only recommend if you can get them at the price i paid ($290 shipped for 4 brand new struts, $150 shipped for used GC coil setup). For under $500 bucks it is so many leagues better than oem suspension, a little harsh on dirt roads which I expected, but once setup properly the car actually feels really planted in the canyons. No real track time here.

Went this route as well, and it was successful. $70 shipped.

Was not 'perfect' - unfortunately, one of the end tanks was cracked, maybe got jacked up during shipment - but they replaced it free of charge.

The downside to mine, was it didn't come with the mounting points attached. I had to rip the old mounting points off my OEM one and bolt them to the radiator. Only took me 30 mins or so, and worked perfectly.

How do you all feel about stainless steel oil/coolant lines? Such as, the ones from Flyin' Miata.

Initially I was planning on buying a set just to make my install easy and clean, but money talks, especially as I get closer to getting all the parts together to do a complete install.

I've not seen the FM ones in person. Check out the plumbing and lines MicaCeli is using in his build: https://www.miataturbo.net/build-thr...t-years-70720/

I wish I could say that I built it myself but this was just too good to pass up for the price.

The heat shields are from Begi.
Now tell me that's not clean. I think Abe still offers these, you might email him and find out. Looks like a winner to me.

I use the hard line kit instead of the soft line kit for the same reason that I bought a turbocharger instead of a N2O kit

Anyone make a DIY manifold and wish the would have done stainless instead of mild or vice versa? Anyone build one and wish they would have just bought instead?

regrets:
  • 1.6L motor.
  • 90-93 body so I had to upgrade: clutch, brakes, diff and still have a floppy dick chasis.
  • blowing my first motor after about 15mins into my first test drive with boost (I had my timing advanced and still had 87 octane in the tank)
  • buying another 90-93 after I totalled mine and didnt want to have to get a new manifold and DP for the turbo setup.
  • buying a turbo from MJM Turbos
  • ever bothering with FMU, Fuel Pump, Bipes instead of going straight to EMS
  • swaping my 12x12x3 IC for a 18x12x3 IC
  • swapping my 18x12x3 IC for a 18x6x2.5 IC
  • buying an ebay IC at all
  • building an IM and then selling it because I blew my motor
  • buying frame rails and then selling them beause I blew my motor
  • Buying seats and harnesses and selling them because I never track the car
  • not tracking the car
  • Doing a coolant reroute and reusing a gasket so I have a coolant leak now
  • Upgrading to 11" Corado Front rotors
  • not buying the 50 trim Chinacharger sooner
  • Koni Shocks w/stock springs
  • Koni Shocks w/FM springs
  • Koni Shocks w/sleeves and 550/300 springs
  • Koni Shocks w/sleeves and 400/250 springs
  • Not selling my Koni Shocks fast enough
  • Burning up two MS3 CPUs from asshatery
  • Buying used injectors from this site, twice, and both times getting things not as described. First was low ohm injectors listed as high, the second had broken pintle caps and I paid to have them cleaned to find out.
And now I don't have the motivation to really work on the car anymore, so it is what it is.
