I am not sure of the exact turbo model. It is a T25 that I got for $20.00 used. It runs about 6-7 lbs thru the FMIC. I have a PLX M300 that I plan to check the AFR. Right now I am working on the Turbo Fueller for ignition control and fuel enrichment. Once I get the TF unit running I will upgrade the turbo to a GT2860RS. I will post more pics shortly.

Here is a pic that shows the two injectors mounted. This was a primary rail from a 1993 Mazda RX7.[img]http://imageshack.us/a/img407/1127/sdc10093z.jpg

This pic shows the adapter plate for the turbo and downpipe.

I got the PLX hooked up today and found that the engine was running to lean. The 3mm screw to adjust the AFR is gone. I do not think that there has been one on the fuel dizzy as long as I have had the car. I removed all the shims from the pressure regulating valve and was able to get a fair AFR. I have not turned up the boost passed 7lbs yet. Between 5-7lbs I am seeing 12:1 to 10.5:1 on the CIS only. I have no need to add fuel from the extra injectors at this time. The GT2860RS is the next step along with a knock sensor.

I'm running 0,6 bar of boost and I just made the wur adjustable and raised the control pressure little bit higher. AFR was showing 13.5 at full throttle.
Here is a small video: http://youtu.be/CAzfeL09zMI

13.5 is generally pretty lean for a turbo car, unless you raised the control pressure after the video? I would want to see the afr closer to 11.8-12.2 at wot.

Going to run it more rich flosho, as the video shows it was the first test run and it ran like that. Maybe tomorrow if I got time I will tune it closer to 12

I just adjusted the mixture, ran on 3rd gear wot with 12,4 AFR. I have to get new water temp meter because the car got overheated when I got home and the meter was in the midle of cold and red... :/

It's not the meter, it's the head gasket.
