Reppin651's $320 turbo kit
Hello all, I’m new here but have been boosting Hondas for a while. I sold my 98 civic turbo and bought this 91 RBG Miata. My first impression of a Miata wasn’t to great; it was slow, heavy, bad gearing for 80+ mph and didn’t really like the feel of the shifter for these tranny. However the convertible, rwd won me over... plus I didn’t have to worry about it getting stolen compare to hondas
. None the less here it is. It's a little higher mileage but runs great before I decided to boost her.
My parts so far consist of as follow:
DSM t25 turbo-$FREE!
Egay mani/dp-$150
Egay bov-$20
Intercooler-$60
Piping-$40
Misc-$50
Total spent-$320
I wanted to retain the a/c so I did the over the rad intercooler piping and had to mod the brackets pretty bad... but its functional lol.
the car
front
radiator
Just enough space for the condenser to fit between
bov
Hot side
Had to modify the wg bracket lol
$5 brace to support the turbo
turbo
Another shot
fmic
Still need injectors and megasquirt, but I'm happy with the $320 spent lol probably be able to buy a mani with that only. I'm not worry about it cracking because I was going to weld and brace the heck out of it later.

WTF +10 on Heavy and shifting... Even a worn out bushing shifter in one of these is better than that rod/cable garbage FWD cars use where you can't even FEEL the transmission.. Just opinion.
Nice build, though.

lol my honda weights about 2000lbs/200whp>2000lbs/100whp. And I like the feel of my civic shifter, a lot more firm, just a preference I guess. I just got done with it yesterday, had to take out the old studs from the cat and put smaller one in to bolt up to the egay dp that rubs against my tunnel wall.

You'll want to use better couplers than those drain connectors. They soften and will slip when hot. What is that you're using for oil feed? Does the brace have heim joint ends? What are you going to do for an intake/filter? how much did you have to modify your hood?
I'd like to see how much power you can make. I'm gonna be using the same turbo, but couldn't find any miata related info for it. Dsm guys say its good for 250hp (on a 2.0L). 200hp seems attainable. Here's my setup:
I think clocking it would have saved you a lot of cutting/welding. I didn't have to modify the wastegate bracket/actuator either.

Gotta love the cheap and effective megan racing parts even if they dont fit gj man. As for the shifter pull that sucker up and see if your pivot ball isn't worn then if it is replace it or the whole shifter, im betting its worn allowing more slop than usual i know mine is pretty much solid where ever i stick it.
