1.6 stock ecu budget t3 turbo build help!
 

https://cimg5.ibsrv.net/gimg/www.mia...df5a694e7.jpeg
So I recently watched Greg Peters do the broke and boosted project and decided I wanted to do the same on my 1.6 93. I currently have a Vortech fmu, 1.8 injectors, a t3 cast log style manifold, an innovate mtxl wideband and a aem truboost solenoid and gauge. I would also like to run an intercooler (probably an eBay cx racing one) I’m looking to get around 150-160whp running around 7 or 8psi but don’t understand turbo sizes and am worried I will buy a turbo that is too large and will not spool. My budget is around $250 for this turbo however I’m willing to budge if it’s worth while. Before I get yelled at for not running a stand-alone ecu i will eventually upgrade to Megasquirt at a later time I just thought it would be smart and economical to go little by little as this would be my introduction to the turbo world. Any tips through this process would be a huge help, thank you!

Step 0: don’t do that.

Steps 1-6:

It's not smart or economical.
The words to describe it are: stupid and idiotic. Also waste of money.
Spending money twice, and buying parts no one will want or need, is never smart.

Definitely install turbo and drive it.

Then down the road, much time afterwards, install the thing that lets you run turbo safely.

I am around that power level on an intercooled supercharger setup.

The best improvement I made to the car was installing a stand alone, even when N/A, bar none. Everything ran better, the car responded quicker, eveything worked. Do it right and do it once.

Can you do stock ecu, yeah. But the amount of time you are going to spend trying to get it to run well just isn't worth it.

I wonder how many good cars that stupid series has ruined.

They seem to misd the part where he switches it to an MS PNP2 because it was the better choice....

:)

Buy a standalone, learn to tune the car N/A. You get a much wider margin of error to work with compared to having a turbo.
Do it right or buy it twice. Greg even says in his videos, hes is only a fish in a sea of information. Is a setup like that possible? Yes, of course, that was the point of the B&B series. But he also clarifies that its not the /proper/ way to go about boosting a miata.
If youre going to buy the standalone, you should only ever buy it first. Use the video series to understand the concepts behind adding the turbo, not as a guideline for your own build.

I'll tell you what, I there were days I would miss the simplicity and consistency of my FMU/Bipes setup....


keep it under 7psi, with conservative timing, and it will be fine until you can finally upgrade.

I’d only be running it for a month maybe then it would be stored for winter and come spring I wi haves standalone and new clutch. Like I said it’s more to see if I could do it because a lot of the parts needed for it just happened to fall into my hands. I just need help deciding on a t3 turbo that will work well on low boost 4,5,6,7 psi and really well come spring when I have the standalone.

There are not any.

not with a 3" exhaust at least. The wastegate on my real garret T3 50 trim, with my 2.5" DP and 2.25" exhaust could keep me at 6psi. :P

:rofl: y u lyin doe

Who hacked Brain's account? Scott you in there? Blink twice if you can hear me....

it was just set and forget is all; there was something nice about that.

also remember a lot of what we were doing was pioneering too, so I was constantly wrenching and breaking shit with shitty custom parts. There were times I missed just running 170rwhp, on the stock ecu, on a setup that was reliable each and every day. that's all.

I've actually read your thoughts on this.

In this kind of situation, what would your recommendation be? Given it comes with the corollary that megasquirt makes so much more sense.

I wouldn't attempt to boost an NB on a stock ecu.

remember I had a 1.failaides

set it and never forget it cause every time you drive it, you're reminded of the mediocrity

I think I’m just goin to go with a Garett t25 it seems safest and worth the extra money for the piece of mind. Not to mention my friend is selling his. Just need to find a cast manifold now

rofl. well played.

I give up. After ordering and returning 3 different widebands and finding that none of them will communicate with my stock ecu I think I’ll have to go with a standalone. Which leads me to my next question: where can I find and what is the cheapest and easiest tunable ecu money can buy?

Just stop. Find a new hobby.

Learn more then lurk craigslist. I regularly see MS PNP and Reverant setups on there with the same story of 'welp I got my girlfriend pregnant, gotta sell all my gofast parts'.
It's how I'm slowly piecing together a build.

*buries face in hands*

please do research yourself. If youre not going to put effort behind your questions, nobody here will put effort into answers.

lol sorry, i kinda tend to learn things by trial and error. Measure once cut twice... Also I'm new to cars. I bought an engine blown miata for cheap and engine swapped it in my garage alone with no ones help, not even the internets. Just kinda taped off everything so i could put it back together. Now that the projects over I thought it would be cool to start a new project putting a turbo on it. Sorry for the trouble.

No trouble. Acknowledging stupidity is a good start. Now work towards replacing it with knowledge by reading and learning

Seriously, most of what you need to know is in post #2 of this thread.

Stop doing everything (everything!) and Megasquirt with wideband. Don’t do anything else until you’ve completed this step- otherwise you’re going to waste a bunch of time and money.

Read the FAQ’s here. People took a lot of trouble to write them.

Details? Trying to figure out what you were trying to accomplish.



DIY Autotune MSPNP Pro.

OP do research it’s all here on this forum. There’s no ‘cheap way’ to boost a your miata properly unless you take lots of time waiting for people to sell their used turbo parts for a little bit cheaper than regular price.

At $1200, it's not really the cheapest/ and/or easiest.

I'd recommend a prebuilt DIYPNP at half the price.
