SOLD! 1991 Mazda Miata - Turbo Built GT2560R Megasquirt
1991 Mazda Miata 233,000 Miles 1.6L Engine - Turbo Built with forged internals Less than 5K Miles 5 Speed Manual transmission with Torsen LSD
LONG STORY (IF WANT THE SHORT STORY, SCROLL DOWN) This Miata has been a project of mine for the past 7 years. It has gone through various stages and timeless upgrades. All supporting mods to push 350+ to the rear wheels, thanks to that Garrett GT2560R Dual ball bearing turbocharger. Mated to that Flyn’ Miata turbo manifold. The last major project to this car was a wire tuck and freshly painted engine bay. That black powder coated valve cover pairs real nice in that engine bay.
Just recently, a new law went into place regarding loud exhausts. Something to the tune of $1000 fine. That’s just ridiculous. Luckly, this Miata has an electric exhaust cutout. Yes, that’s right… Going from a quiet stock exhaust note to a deep rumble with that sweet spool paring nicely. All from a flick of a switch.
This bad beast of a Miata is running a 3” downpipe, all the way through the 3” electric exhaust cutout which goes through a riveted aluminium plate in the rear bumper… It looks really sick if you ask me.
The dashboard is complete. That’s hard to come by with used Miata’s. Especially that gauge cluster hood. Apparently, that’s a rare commodity for Miata’s. The dashboard was upgraded with saude particulate fabric, just like them rally race cars. It screams sexy as MF.
Anyway, here is the complete modification list:
[ENGINE SPECS] 1.6L Engine - Built, balanced and blueprinted 1mm overbore H-Beam piston rods ARP Bolts Supertech Pistons / Wiseco rings 8.8:1CR King Racing Bearings All new gaskets and check valves New OEM Oil Pump New OEM Water Pump New OEM Timing belt Powder coated valve cover
[ENGINE SUPPORTING MODS] Garrett GT2560R Dual ball bearing turbo FM Turbo exhaust manifold Fly’in Miata Stage 8 exhaust manifold hardware with inconel studs ←---------this is baller **** right here $108 for exhaust manifold hardware, aircraft quality for sure. That nut aint ever backing out with these badboys. Say goodbye to random exhaust leaks!) Turbo XS BOV RFL (Really ****** Loud. No joke, google it. It sounds like a fresh soda bottle opening, pshaaa! Or like a big *** whale surfacing for air. Pshhhaaah!) Begi Coolant Re-route with new Thermostat CX Intercooler CX Radiator 2.5” Custom intercooler piping Flyin Miata K&N Cold Air Intake System Custom 3” Exhaust with Electric Exhaust Cutout (Car still has stock exhaust in the back. When the cutout is closed, exhaust gases go through the stock exhaust. Once the cutout is open, gasses exhaust through a side exit in the rear bumper, 3” inch of unrestricted airway for the turbo to breath. Driving in the fastlane, cruising next to the freeway divider has excellent acoustics. Imagine driving this car, with the top down, and hearing that sweet Garrett GT2560R dual ball bearing turbo spool along with that deep exhaust rumble….. Wind in your hair… A great feeling.
[FUEL MANAGEMENT] Megasquirt II V3 NB 254CC Injectors / 450cc RX-& Injectors (Cleaned and balanced) AIT Mod AEM Wideband 255lph Walbro HiFlo Fuel pump Antilag. Seriously, don’t antilag in crowded places. This little car will scare the living **** out of people. Yes, it’s that loud and violent.
[DRIVETRAIN] Stock NA 5 Speed Transmission 2001 4.1 Torsen LSD - This drifts nicely. ACT HD Pressure plate ACT 6 Puck race disc Stainless Steel clutch line 8lbs Lightened aluminium flywheel Shifter rebuild kit Motorcraft synthetic transmission fluid

Megasquirt is currently running on a street tune map on the 254cc injectors at 6-7lbs of boost.The tune still has lots of room for improvement. The next step is to buy a decent set of injectors (the 450cc RX-7 injectors were difficult to tune for idle due to the pintle style design. poor particle atomization). Decide if you wish to run E85, or straight Gas. Megasquirt can handle large CC injectors, so it’s totally scaleable. Throw in a new set of injectors and some time on a dyno for a good WOT tune session to unleash the 14-18psi beast. Don’t get me wrong, rolling the streets at 6-7psi is still a lot of fun in this tiny *** car. Banging in 2nd and 3rd can chirp those rear tires pretty loud. Don’t underestimate that GT2560R turbo. Thanks to the dual ball bearings, full spool kicks in sooner in the RPM band. Hits even harder when you have the exhaust cutout full open.
Why am I selling it? I am trying to move out of my parents house and I need to get all my **** liquidated. Things happen and things change. So, all my hardwork can go to someone who appreciates Miata’s and can take her to that next level. She’s built for it but she needs a good owner to take care of her and really enjoy every moment in that car.
It’s a fun car. I never liked Miatas because I thought they were really unmasculine cars. Oh, I forgot mention I threw on a body lip kit to give it more of a manly appeal. Anyway, Miatas drive like no other. With the top down, sometimes it feels like I’m in this go-kart cruising the streets of San Diego. It’s such a fun Sunny San Diegan car.
I’m asking a measly $7200 for this whole thing. I am open to offers but please make them reasonable. You should've seen this car when I first picked it up. **** didn’t even run! I had to tow it back to my parents house.was missing all kinds of ****. Engine was leaking oil…Clutch Slipping. In the course of 7 years, I gave it new life. Replaced every single missing piece and upgraded everything that made sense.
I need to sell this car to someone who can appreciate it. Comes with a clean CA title. No major accidents according to the carfax. I checked and did not see any signs of frame damage. Everything is straight on the body. The exterior paint does need some TLC. I do have a gallon of red paint left for the exterior. It comes with the car.
[SHORT STORY] 1991 Clean CA title Mazda Miata 1.6L built engine supporting 400hp Less than 5K Miles Garrett turbo GT2560R 5SP 4.1 Torsen rear diff Lots of supporting mods! Electric exhaust cutout with stock muffler 3” turbo back exhaust piping (hidden side exhaust)
Asking $7200. Need to move out of my parents house so I’m liquidating all my ****. Let’s make a deal.
