Default Just another turbo miata

hmm here is what it looked like the day I got it. I purchased it from a auto auction in Indiana last july.



I dissed the silly wheels and crappy tires for 15x8 6UL with hancook rs2's 225/45/15. Its not been real pretty outside since I put them on so I can get a great picture of them.

put some speakers in the headrest, now i can hear music top down on the highway much clearer then before. They are some 3.5" polks. Both seats got 2 speakers put into them for left and right.

So who is ever satisfied with 105bhp? not me... So the deconstruction reconstruction begins.

putting gauges in to monitor new things the car didn't have from the factory.

completed.


At this point the car was already running on a haltech sprint 500 ecu that was installed by lms-efi (also known as ludwig motorsports). Chris has been a friend of mine for 9+ years now.
The front mount shows up and the kitties are real interested in whats going on...

mounted.

the cx racing comes with some off brand BOV. So I replaced it with this one I picked up used.

installed! Welded in a bung for my Intake Temp Sensor.

I am using a hallman pro boost controller, it was just a short term fix. I will let the haltech controll the boost.

oil return line, chris drilled and tap the pan and made this line for me.

pic of what the car looked like after the kit was put on.


Somethings not pictured at this point, replaced oil pan gaskets, replace cams seals, new thermostat, installed rx7 injectors, FM miata stage 1 clutch with 13lb flywheel.

Injection nozzle. Picture kinda sucks its actually underneath the pipe.


pic of the car with its new shoes on.


Ordered a 3" downpipe from Artech, Abe does beautiful work!

Here is the downpipe installed

The rest of the exhaust before it went on the car. 5x11x22 muffler keep its wife friendly.

nice preturbo water injection, I have plans to do that -water pump.
But with mine the water mister will be setup right in the middle of the filter aimed straight at the middle of the turbo blades.
nice exhaust, v bands yes?

Why do you say fail reverant?

I am thinking about doing it too, in addition to my direct port WI

My thoughts are that it would help spool up and also reduce AITs.

There are spare maps and outputs in the hydra I could use to drive a high speed valve.

I like your build, but please upgrade the pre-turbo water injection to a proper, tried and true system with a high pressure pump injecting just before the throttle body. You've already got the nice fittings and nylon line, so you don't need much more.

Why do I care? I've been using water injection since 1997, have helped countless people build install and tune their setups, and have hosted one of the first DIY water/alcohol/methanol injection websites. I can tell you for a fact that pre-turbo injection is the least optimal configuration for real performance gains, and have personally seen this method damage compressor fins. Nothing personal, but if you're going to do it, do it right.

I have a 250psi aem pump behind this injector I do plan to run another injector pre tb when I upgrade my ignition. I would love to read your data that you have collected regarding pre turbo water injection. I am aware the risk to the turbo, I have another one like it if I mess it up. I'll collect some of my own data as I go, suggestion duely noted though man, I appreciate it!

So how do you do it right if you want to inject pre-turbo?

I'd like to do pre-turbo for faster spool but am concerned about potential fin damage. It looks like even if I spray directly onto the compressor when I lift off throttle I will still get pooling in the intake.

From what I've read different mixtures will have different evap points. I'd look into that more.
I do know another turbo miata owner with pre turbo water injection. With only 91aki ca gas he could only get to 12~ psi on his setup before det, with water it was around 16psi and know with some alky mix its near 19psi

With 100 aki he can do 20psi without water.

He is of the opinion that you can't do it right.

How do you plan to do yours with no water pump?

turbo pressure will force water out of the resovoir into a mister nozzle that will also have a pressure line run to it with a water line as well.
Probably be few other parts, solenoid, and a resovoir low level warring system, but I think thats about it

You think you will get enough pressure for atomization? I'm unsure that you will, but you could test it I suppose.

atomization, doubtful, but I do know it works because as I noted above, friend with turbo miata and pre turbo WI, is using this setup
