FS: 1991 Mazda Miata (1.8L VVT/Rotrex)
 

Hello,

My name is Will and I’m selling my 1991 Miata. I’m starting my masters soon and could use the extra money to pay for classes. All the below modifications have been done by myself (automotive engineer/ASE certified mechanic) and all maintenance has been done religiously. The car has 3 owners (me included) and has never seen snow ever. Since I have owned the car, it has been garaged in a climate controlled environment. Everything works, and there are no lights on the dashboard. Otherwise, it is an incredibly clean “get in and go” car that puts down some crazy laps or some great fun on the streets. I will include a write-up with all modifications and where to get any specialty maintenance items (supercharger belts) if you need in the future. Clean title in-hand. I'm asking $9,700.

pics dont work

Fixed.

*Disclaimer* Pictures are before I made the custom airbox. I'll upload those later.

How much power does it make

I'll post the dyno sheet when I get down to my desk again, but It made ~235 whp on Pure Tuning's Mustang dyno. ~250 whp SAE Dynojet converted.

Great looking build, I didn't see where you're located.

Wow, if I wasn't buying a house, I would be tempted to sell my car and buy this. Everything done right from the sound of things.

Are any parts of the stereo system still installed?

Just going to leave this here...

Where are you located?

Reading is hard ... just saw that you're in Michigan.

The wiring is still there. If you wanted to add it back, you'd need a headunit, door speakers and a panel to put the headunit in. But why have radio when you have the glorious sounds of the supercharger??

Thanks man! Rochester Hills, Michigan (48307).

Yeah I get that. Real life comes first, that's where I'm at too unfortunately :(

Yep that's my brother. He has a good "sights and sounds" video of the car too.

hahaha replied to your PM.

What kind of temps would you see on the track with that Rotrex?

Interesting
 

I've seen the video before I learned it was for sale. I am willing to buy it this week if that's okay with you. PM me? I'm new idk how the site works

Like 205-210 deg F coolant temps, not sure on oil since I don't log it. That's the beauty of the Rotrex, you just turn it on and go without worry. TDR makes a great kit that gives you a good amount of quality ducting. I did some more myself.

Small world! Pm'd

Pm me. I’m very interested and in the market to buy.

Sale pending. (sold for asking price)

Buyer bailed, up for sale again.
