Re: Oregonmon's white 1990

This is my first Miata, but not my first fun car. Sold a 1979 Porsche 911 SC for this 1990 A package. Power steering no A/C.
Purchased for $5000. Including hardtop extra tranny, viscous LSD, new set of rotors pads, recent water pump, timing belt job, box of other OEM parts and a stack receipts.

This is how the Miata sat when I bought it.
Good selection of basic bolt ons for a fun street car.
Hard dog double diagonal bar
frame rails
14x6 Panasports with Falken Azenis with 25mm spacers
TSIs
FM front and rear sways
Koni sports with FCM top mounts and bumpstops on stock springs
Snugtop hardtop with rear defrost (never hooked up though)
Aftermarket stereo and speakers with aux input
Ebay catback exhaust

I plan to go through and document what I did and how I got to how it sits now, took lots of pics along the way.
Thanks for reading.

Re: Oregonmon's white 1990

Thanks. I've actually been on now for while, I just never had a build thread. Now looking back I wish I would have started long ago.

Re: Oregonmon's white 1990

Never knew your top was a Snugtop. I still want to try a hardtop on my car.

Also, post pics of ticket plz.
yes, do tell how you ran a red light trying to keep up with a loaded down Honda Odessey loaded with miata owners.

Re: Oregonmon's white 1990

I've been running a depowered rack for a while now. The simple way of removing pump, belts, lines etc. But I wanted to improve on what I already liked about the steering so right now I have the rack out to remove the metal seal and address the play in the pinion gear. I was planning on having it welded, and I let my friend take it to his work but once the welder started to look at it they decided that it was not the best way to address this. So they ended up drilling and putting 2 pins in at 180 degrees from each other. They're press fit and glued and should be plenty strong, this is a large company that produces commercial chainsaws and I trust their judgment.

Oregonmon's white 1990

Another part of this project is to UP the spring rates from the 375/250 Ground Controls (on Konis) to 550 springs in the front and send the 375s to the rear.
Here's what the FCM top hats, 36 mm tophats looks like.

Re: Oregonmon's white 1990

An emphasis needs to be placed on weight reduction now. I think I convinced him to ditch the shock tower brace and convert the driver's side to a master cylinder brace. Also, if we can get the airbag light to turn off, he was all for deleting the heavy air bag sensors (x3), and possibly even the computers and plate under the steering wheel mount.

Looks good! Would look even better if you sold me that hardtop! :) Keep up the good work.

Re: Oregonmon's white 1990

I do currently have a stock rear bar on but with the new rates 550/375, it might need to come back off. The rear rates seem to be a little higher than the norm with 550 front.

Josh, I like your thoughts about being weight conscious. It's something that's definitely in the back of my mind, last week I put in a 11lb AGM motorcycle battery, replacing the wet-vented Miata battery at 20lbs. You definitely know more about what is useless in the engine bay than I, especially when it comes to electrical tape. :)

Not too long ago, AR put it on their scales, and with hardtop it was 2200lbs. So being topless for autox, I'm at 2150lbs. Since then, I've maybe dropped another 15lbs here and there.

Re: Oregonmon's white 1990

Here's said battery. Gotta come up with a more solid spacer. We'll see how long it lasts. 230CCA.

Re: Oregonmon's white 1990

Search around about the airbag light, that's a big savings between everything. Maybe around 10lbs. An easy one would be taking the hardtop off some day, folding back the rear deck carpet, removing this panel:



And getting all the foam out. I could feel more with my finger tips, but it ripped when I removed one of the chunks the other day. That stuff is dense and heavy!

For others reading: the car's previous owner stuff an insane amount of memory foam behind that panel and in the gaps on either side of the gas tank for sound deadening. Ryan said he removed a bunch earlier, I found a few more chunks. He definitely removed that panel himself and put it all over the place.

Roll bar also needs to come out eventually so so it's not bolted on to a pad of insulation.

Re: Oregonmon's white 1990

Here's some more of Curly ' s handy work. He did an awesome cut of the rear bumper with a jigsaw. It was the exact look I was hoping for. We cut up the bumper support a bit it mount it back on and the rest of it is sitting on the shelf. Needs to go in the garbage.
