$2000 turbo nitrous miata - good, bad ugly
Hi guys,
I was searching for a nice 1.8 to start a build with but came across this 1990 1.6 that I wound up buying because it was inexpensive. At some point it looks like someone spent a lot of time and energy creating brackets and welding up custom piping. It all appears well done. The car also has a nitrous system installed with a fogger in the intake, 10lb bottle in the trunk, WOT switch, MSD window switch and purge system. I plan to basically pull all that out and sell what I can to recoup some money. Right now the car is running on the stock computer and a FMU. There is a narrowband and boost gauge added to the a-pillar. I've already bought a AEM wideband to swap in early next week. It's boosting 3-4 PSI and the narrowband is almost always in the "rich" portion of the gauge unless I am steady state light throttle where it bounces back and fourth like normal. Car also has a 1.8 rear end, not sure if torsen.
My plan is to buy some injectors, a fuel pump and fuel pressure regulator along with a megasquirt PNP and learn on this car. Some things I notice is the seemingly poor placement of the turbo inlet and a tight 90 degree inlet. I'd like to have the more experienced eyes take a look and tell me the good, bad and ugly of the current setup on the 1.6. I'm hoping to learn the tuning on this car and either swap in a 1.8 later or buy a different 1.8 car altogether that's cleaner. I'm hoping to get in the 200+WHP range with this car after the megasquirt and turning up the boost. I'm guessing it's running around 130-140 whp now? See the attached pics, i'd appreciate any comments on the current setup.

I think its a decent buy, it has an ok looking turbo kit and the body is clean.
get rid of all the crap, nitros, msd, afpr, afm etc...
get a megasquirt, bigger injectors, tune it and crank up the boost.
im sure it will make 200hp if the motor is healthy.
dont worry about the tight bend on the intake, youre not going for 400hp, so one sharp bend on the intake will not make a difference.
once you get rid of the afm, you can eliminate the second tight bend that goes to the filter.

Thanks Borka, kind of what I'm thinking. Glad to hear that bend will not be too detrimental. I'm not racing the car, it's just for street use and I'm not needing every ounce of power.... The body looks better in the pictures than in person, hood, front and rear bumpers and rear panel all have paint issues. There was a body kit on it so there are holes drilled. But it does not have major rust issues which is a big plus here in Wisconsin.
Anyone have any idea what turbo is on this thing? I'd like to find some people running similar setups to help me get a base map going. I still have a lot to learn as far as mega squirt goes. luckily I have a co-worker who is running mega squirt on his turbo fiero that's 400whp+ who knows what he's doing.
Thanks,
Nick

looks like some kind of T3 turbo, no ideal what kind though.
get flowforce 640cc injectors, ms3 and use the base map that comes included. that should get you started.
Then just autotune fuel and that would get you 90% of the way to a decent running car.
rest is just fine adjustments for starting, throttle tip in, AC compensation, etc...

Also sticks out a good distance from the back of the car (looks dorky to me) and is loud for my taste.
A question on MSPNP2 vs 3 (and I know I have a lot of reading to do), what options does a PNP Pro provide to someone not running a VVT. The only thing I will probably do down the road or one day is swap in a 1.8 (probably not VVT). I do want to run sequential injection.
Thanks,
