So when you said unplug the IAC I am pretty sure you mean once the car is warmed up. When I unplug it what should happen if the IAC is good? Also should I use diagnostic box jumper when I do this? Thanks

I went to an exhaust shop and got my Hotside IC piping fixed. Before it contained aluminum piping, silcone couplers, but also had...PVC piping, home depot couplers, and bendable exhaust tubbing. I got a GTX 323 PCV and cleaned the Intake manifold again. With all of these changes my idle is completely fixed! Now just saving for MS so I can run my WI and turn up the boost. Right now I am maxing out @ 5 psi and the turbo is loud...is this the wastegate maximum boost or does it sound like I have a leak? I will try to get a sound clip today...thanks again for all your guys help. My miata is now just as worry free as when the motor was stock, but now its like 10 times as fun.

Is anyone running an heater core near the water cooled turbo? I have a new heater core sitting around and was just wondering if I would see any difference. I plan on mouting it behind the radiator to pick up the cooler air from below...it is about 9 by 8 inches. PS I am running @ 202- 208 when my car is sitting...

Just checked today and I have huge shaft play...does anyone know a good rebuilder or a good cheap turbo (t2 inlet). I bought both turbos used and both were super cheap so I guess I get what was coming to me. Please let me know any good preferably local (LA) locations...thank you.

Ryan, Call up Church Automotive. They are local to you and do tons of tuning for FI cars and are really nice guys, I am pretty sure they can recommend a rebuilder if not themselves. Or try David on HT. He works with Jerry Built and thats a small company that is putting out huge numbers so it might be cheap

Hi guys, just wanted to update this...I am now running my Progressive DOWI, along with now using a Uego to monitor my A/f...I installed a new t25 with a 8 psi wastegate. Here are some pics... Next on my list is to get MS so I can get all the power, & more importantly tuning capabilities. But as of now with the FMIC I am having no problems. Please I am open to any comments/suggestions/advice, also does anyone know a good place to it dyno'd in LA area? Now for some pictures.

I know my oil feed is ghetto rigged along with the intake arm, but I should be taking care of these in a while...also the wheels are now polished by hand, not great quality but it gets the job done.

Update for this...yesterday I used the largest nozzle from my DO kit and I am now almost perfectly stoich. When I boost approximately 3-6 pounds (WI comes in @ 2psi) I am running anywhere between 13.7 - 15.1...I am super happy with it
, but I will still be adding MS to it (building it next week) to actually be able to tune.

Lean as **** would be more like 17+. My MS will probably be operational hopefully in two weeks, but honestly why should I not boost, my set up has been going strong for a few months and I have had no problems with the car, (had to replace the turbo, because I purchased crappy used ones that were already set to fail). I have not once ever had knock/detonation, and that is a lot more then some people can say running MS.

13.5:1 would be a good target for 0psi (naturally aspirated). I consider anything leaner than 13:1 on a turbo car to be lean as ****. 17:1 is where you'd lean cruise if you were trying to save gas. You're going to start melting pistons if you continue to boost on the car with AFRs in the 13.5:1 and up range.
