so I am kinda new to the Miata world. I've owned my car for just about a year, it's a 1990 1.6L 5 speed. I've been thinking about turboing it but I don't really know what I'm doing.. I've been pawing around on here reading different things and trying to learn as much as I can. I'm a little tight on $ but who isn't. I was thinking about flowing The car passion channel and broke and boosted set up, or just going with a header, cold air intake maybe a Throttlebody spacer and Port and polish the intake.. I'm not trying to build a Car that's the fastest car out there but just something to "daily Drive" (I have 2 vehicles so if I Break it I can still get around) and troll on some kids every now and then. So bring on the thoughts.

 

Buy a megasquirt (some flavor of MS3 preferably) and have fun learning to use it. It will never become worthless, and it lets you play around with things without spending money. Satisfying the desire to tinker and learning to tune at the same time is about the best you can do when you don't know what your final power plan will be. Buying a throttle body spacer is about the worst.

 

Don't mod your daily.

 

I have thought about buying a megasquirt before.

 

I wouldnt recommend moding your daily either because if u never turboed a car before it will take u around 2 to 3 days trying to install it. Broke and boosted is good up to 4 to 5 psi only. Even thought it will be more fun try to get a ms and Swap your differantial for a 1.8 and of course bigger injectors like the yellow rx8 injectors rated at 425cc they fit just like stock and easy to find(you ll need a ms to run them as stock ecu wont be able to read them) , pull a junkyard t25 turbo from a nissan and rebuild it, buy the turbo manifold from flyin miata go with a custom intercooler piping and try to get a good intercooler you ll need a shop to fabricate you a downpipe as in my opinion it will be cheaper, consider also a recirculating blowoff valve and a wideband o2 sensor with the gauge

 

throttle body spacer

 

Uhhhh he said he has two other cars.

 

MS3 of some sort and a wideband O2 sensor. Those along with removing the stock AFM will pick up about 10whp. It is the best bang for the buck out there power wise. It also sets you up to be able to go whatever power route you want in the future.

 

I would like a wideband o2 with whatever way I go even if it's not turbo. I have looked around a little for a used lsd but they seem to be a little more then I want to spend although I have been told that it is a very good first mod. How much dose a set of injectors run?

 

1.6 rear differential fails at stock power levels.

 

Wouldn't the OP see a pretty big benefit just going to a 1.8 open differential if he chooses to stay NA? The 90-93 diffs were pretty awful, no? Shouldn't be too pricey to swap and you can throw a torsen in there and do the work yourself if you're on a budget. Should still be cheaper to do than buying an entire torsen pumpkin unless you get lucky.

 

guys he just asked how much a set of injectors run. Isn't anyone going to spoonfeed him?

 

How much? allofit

 

OP, folks here don't like spoonfeeding.

I started a thread asking a question after doing a bit of a research that might answer a few questions you have re directions. Hope it helps: https://www.miataturbo.net/general-m...u-think-90818/

Also, read. A lot.

Oh come on. If it's a slow day at work, I'm sure you'd be down to copy paste that little thing you have saved on google drive for which injectors and what they're good for. I've seen a few folks with responses like that and they're gold for moments like this. Takes the same amount of time to copy paste that it does to post a blistering response haha.

 

but where's the fun in that?

 

OK.

Injectors go for $40 - $700.

That's the only information that takes less time than giving him ****, so that's what he gets.

 

This is all very good info and I thank you all for it. I do my research when I can.

 

 

Is an AC and power steering delete much of a horsepower gain/good idea? Lol

 

No.

Delete the AC only if you don't use it. Delete PS only if you want manual steering.
