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:vash:. 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.

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.

nice build for 320! what did you use for piping and diameter did you use for the IC? Lookin to do the same thing for my setup.

What about fuel/timing?

I order a 180 bend a 4ft pipe, only needed about 1ft from the 4ft pipe. Its 2.25''

Not bad! Not good. But not bad!

I have dsm 450s laying around but I'm waitng till I get megasquirt

I = can't read. Good job so far. I love cheap DIY themes.

Heavy? wtf was the curb weight of your honda?

I know and he doesn't like the shifter either. 2 reasons people love miatas haha.

Nice for the $320 ...... But miatas are heavy??? Shifting sucks?? :bsflag:


Good luck getting your project finished. Post more pics once you do so.

As for the heavy part... yea I think he is just smoking some crack, or just really dislike the stock 95 whp.

As for the shifter, I am betting his bushings are just shot as it is a 91.

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.

That is ugly! I like it.

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.

jesus christ are those home depot toilet bowl couplers?

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.

Sprayed your welds on your pipe look just as nice as my future mani/DP!!! lol

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. Gl man

I with him on the shifting part though I have a 6 speed I still like the way my honda integra type r shift. I have owned 12 cars and I dislike the shifter on this car the most out of all them.

you honda guys are some weirdo fucks, would rather feel the notching of the shifter cable than feel the lever pivoting in the transmission turret?

Whatever floats your boats, rite?
