I've only got time/$$$/space for 1 toy, and it's the miata. So i'm not getting one anytime soon. I've always loved them though.
The 3rd gens were the lightest werent they?

Yeah the spyders are on par with the 85 first gens. My STS car is at 2270 or so weight wise and the spyder is around there also. MK2 NA's are actualy in the 2400-2500's.

The problem with the spyder is the motor, although fun in that car its just not good enough. A 2zz swap is a nice motor for it but has a very peaky power band...think s2k but even worse. There are guys that are swaping the 2grfe v6 motors into them. 300whp and tq in a 2300-2400 lb car isnt all that bad.

I always thought a nice MRS with a 2zz swap would make a nice "poor mans" elise. No idea if handling is comparable at all though.

It could be close but the limitation of having full Mcstruts all around would get you. Cool thing about the spyder is that all the body panels are bolted on so you can put moar tire on it and bolt on some wider panels to compensate. Out-tire the Elise and setup the struts realy realy well and you could get very close.

Elises are so much purtier though. I am still thinking of getting one...I just have no idea what I would use it for. I seriously would just park it and stare the the dang thing all day.

I had them on my MR2 as well as my Subaru, loved them.
So I put them on my Miata, it's terrible. I'm switching to Bilstein.

Nice garage +1. I wish I can do that without city's permit.

I know I went through two sets thinking my other ones were bad...something something throwing good money after bad.

Thnx it cost money but sooo worth it.

We are DOWN to 8 I think
-88 MR2
-88 S/C MR2
-91 Miata
-91 MR2
-2003 Yukon XL
-2000 Celica GTS
-2003 Celica GTS
-2007 335i sedan stick (Wifes newer toy)

I need to thin the herd. Celica's and 91 MR2 prolly need to go. Thinking of an EVO for a daily but dont know yet.

Love this area as its quite but we need to move somewhere closer to Columbia MD so my Wife doesn't have to drive 55 miles each way to work, plus she wants a neighborhood as we are looking to start a family.

Oh Hornet, thank you for all your posts on the MSPNP tunning. Helped a ton.

That was a pic of when it was first built. I have a bunch of shelving now and 4 96" lights with two bulbs each. Its nice and light in there. I wish I finished the inside. I wanted to run more electrical in there, insulate it and drywall it. A light color would have really lightened it up also.

Threw some enkei RP02 or whatever they are with older Toyo R1R on them on the car instead of the 5 year old Azenis so that it can handle the weather a bit better.

Installed a begi turbo heatshield after cutting it up so that it would fit with the heater lines installed. Mine are in the stock location was this thing made for a full track re-route or something?

Going to the Reston office tomorrow so I should be able to get 100+ miles of logging done...if I can get traction.

Car is running at 12psi at the manifold now, no leaks, no fluids have burned off. It's running a bit rich but not a cruise (I think I am using Brains or Hustlers table). No matter how many projects I complete I am always in awe when things work and am waiting for something to go wrong.

I did have enough issues with this project though:

-The begi coolant spacer had a tiny little ridge that wasn't machined out where the t-stat goes. So it looked like the Kia water-neck was on correctly but there was a tiny little space. Getting it out when it was in the car...was fun. The NAPA stick on gaskets that BEGI supplied were also terrible. Some sanding of the t-stat seat and good gasket fixed the issue.

-My smart self installed the intake manifold gasket backwards....coolant leak. Fixed thnx to a search on MT.net

-Had to redo few fittings and using yellow thread tape on them to seal them back up.

-The best one of this built was when I installed the the new fuel filter. I replaced the lines with new ones that fit fine but I guess were a tad too big. Fuel waterfalls in the garage are fantastic.

I attached my tune if someone wants to take a look at it. Please criticize.

Its fun watching time pass in your pics by observing tire wear and tire changes.

IMO the wrx/sti is a much better daily than the evo, the evo is a much faster racecar.

I know and a STI hatch would be a perfect car for me, I just have way too many Subaru friends and know too many Subaru people to get one. Plus for some reason a Stormtrooper Evo X needs me to drive it.



So I think I spoke too soon about issues. Tach died on the way into work today. MS's tach is fine just the car one. I shall research.

-Put in Auto VTPS…tune
-Read every damn post on tunning on this site.
-Idle is good and logs look good on this motor, time to upgrade.

Brings a tear to my eye.

Nice build, nice garage, and nice other cars.

Turbo noob question: So that brackety thing that seems to be so cleanly managing your coolant/oil lines, from whence did this come and where might I acquire one?

I'm always very jealous of how clean these simple NA builds come out. Good looking project, keep it up!

I was going to put a kit together for this and even bought the FM one. But then ARtec posted this and I could not pass it up:

https://www.miataturbo.net/miata-par...s-39663/page1/

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.

Car is running ok but needs more tunning.

-AFR's while used to be rock steady the car was NA with the old motor, are not all over the place. Need to figure that out I think maybe a grounding issue.

-Need to re-tune idle a bit as I did before...new motor and stuff.

-the pass side headlight motor is still having issues, motors seem ok, plug ohms and volts are correct....got to be short somewhere still. Maybe with me moving the harness around so much might of jared something loose.

-Need to build a bracket and put my new drivers side seat it. The 99 seats that I have are just not the most comfy things.

Resolved my electrical issues:

https://www.miataturbo.net/general-m...77/#post974451

Went out to do some tuning but traction is non existent with the temps being in the 20's.

One fun thing is that even thought I did the minimal coolant re-route heat is very low :( I will need to figure something out to get better heating in the car as it is a nice thing to have.

ANNND I have a coolant leak. Found that the rear Kia neck is leaking with the begi spacer again. Yay.

Also the head gasket on the exhaust side looks wet. I am hoping that its just coolant traveling from the spacer but maybe some ARP studs and new headgasket are in order.

Car is going into hibernation for a bit while I work on my other cars to get them sold and out of the way. Need to complete the S/C MR2 also so I can get it out of the garage.

Did you use the T'stat gaskets that BEGI supplies or OEM?

I'll be starting the car tomorrow with a new engine and reroute (including the BEGI spacer). I used OEM gaskets with the little green rubber O-ring. Here's hoping.
