Hi guys, I am an old timer DSMer from Mass, who ended upwith this interesting 94 turbo Miata. Though I am an DSM expert, I do not knowmuch about Miatas or this car in particular. I can tell that it was someone’s baby,judging by all the mods, but I am not even 100% sure what is stock and what isn’t.
First I have some general questions:
What is this turbo kit?
It has an intercooler (small by DSM standards).
What other mods can you spot?
It appears to have a fuel pressure regulator. And everything is controlled by a blue GreedyEmanage.
























Car has compression, but it doesn’t fire or spray fuel. I am not sure where to start diagnosing thiscar. Being a ’94, this must be beforeOBD2. So my OBD2 readers areuseless. I guess I should try to connectto Emanage. I am very tempted to convertit to DSM Link .

Any advise how to proceed?

Thanks!

 

part out and/or sell it to the next sucker. Way too much fuckery to un ****.

 

Well, that is always an option... But this seems too nice of a shell with virtually no rust to part it out. Whoever built it, put some serious money into it (including V1 radar detector).


PO was from CT, does anyone recognize this car?

 

If you do want to keep it.

step1, remove that piggy back aids
2, get the wiring back to stockish
3, install megasquirt
4, get accordian hose out of engine bay
5, deal with whatever fuckery isnt blatantly obvious right now that you find along the way.

 

Accordion hose used for BOV return line is fine. But I am not happy with the intake part (between turbo and MAF), that will definitely have to be changed.


If I am switching to another ECU, it is going to be DSM Link .

 

I'm still trying to figure out what that thing is in the sixth picture. It's no emanage that I recognize.

Is the stock ECU still present? Look behind the passengers seat.

If so, I'd start by attempting to remove every bit of aftermarket wiring and circuitry and getting the engine to idle on the stock ECU.

 

Thats a terrible idea. This one guy tried to use DSM link, which could maybe actually work since the DSM and NA miata use the same CAS but it was an epic failure. MS just plugs in and works.

 

I custom wired DSM Link into Eagle Summit, which involved making my own harness, Miata can't be THAT much different, especially if CAS is compatible. I have heard of several Miata's running DSM Link with great success, but then, those guys are hanging out on DSM forums .


Joe, I suspect that photo is a methanol injection system, as it is in the truck and has a large tank.

 

Your car looks to have been "built" by a 6th grader with a budget of about $10


Are you a redneck?

 

What makes you jump to this conclusion?


Does this look like any particular turbo kit, or is it all "home made"?

 

Because only a redneck would look at that pile of crap and say "it's got serious money in it".


It looks like a begi mani, with a sr20det t25 on it,
the rest is just hacked together junk. and I really mean junk. most wouldn't buy it even for $50
gauges are ebay junk
intercooler is some oem fitted in
the charge pipes....lol
the fmu means that whatever weird looking juju box is connected likely can't control fuel and timing very well

The frame rails look like FM rails. So that part is good. lol

 

To be fair both mathewdesigns and underdog had great cars come out of DSM Link. Though mathew works at some high dollar shop, and underdog just likes self inflicted pain through huge projects

 

Edit: Aidan beat me to the defensive line

This one guy here typing has a Miata running on ECMLink and it kicks ***. Underdog was the first and it also was a complete success. Nobody else is using it/has tried to use it afaik, though a number of people have inquired with me regarding the setup. The CAS is essentially identical and that makes it all possible, but not easy.

My answer to the inquiries has always been: Megasquirt

OP, do yourself a favor and listen to what everyone said about what's under the hood, forget about using ECMLink unless you like making custom harnesses, and buy some sort or MS unit to run the whole operation.

 

There he is. Can DSMLink be updated to use the crank and cam triggers from newer engines? Or just the 1.6?

 

Ehh, I've not heard of one running like that. A quick search revealed that a two tooth trigger plate can be used (not a typo...two teeth lol).

 

So he would be spending a **** ton of time digging himself into a hole that leaves no upgrade path?

 

I know an Evo8 can be run with ECMLink, and it uses a crank trigger, here's a pic:



Whether he's stuck I'd say the ecu is pretty flexible. I'm running an ethanol sensor with real-time dual-map interpolation for timing and mixture, ecu-triggered fans, integrated wbo2, and external triggers if I find a use for one.

Definitely a **** ton of time to make it happen.

 

Also. This = someone's baby



Not the bundle of snakes in that thing.
/humblebrag

But compared to megasquirt which has 4 different off the shelf plug and at ignition trigger methods.

 

This build was done around 2005/2007 (judging by vintage of parts that I do recognize). Many of thes mod might look (and are) dated by today's standards but that doesn't mean that weren't expensive at one point.

The only gauge I recognize is Greddy boost gauge (athentic). Others look too good for being eBay crap after 5+ years. It has Valentine One radar detector build into the car.

Snow Performance meth injection is not cheap ether.

This was not a $50 build!

Now, I understand that piggyback Emanage with variable rate regulator is a hack system today, but it wasn't exactly cheap 8+ years ago...

 

Pardon me, $60
( I was here in 08, so I remember )

I really hope you're not defensive because you overpaid
