The 3" downpipe won't sound that bad cause the turbo will act as a muffler to kill sound and with a cat your shouldn't have any sound issues.

Search on the forum there is a few vids of peoples car with a 3" exhaust. Somewhere y8s had a vid of his dyno and the exhaust sound so beautiful.

Pipefather,

You can try to run a straight -3AN line, but just based off looking at what the stock oil line is, there is definitely a restriction purposely put in place. I didn't feel like spending the money on a proper restrictor from ATP turbo (.065"), but I found the head of a small pop-rivet to be perfect. Also, I had BEGi custom downpipe for it, and Corky removed one of the studs on the top of the turbo (closest stud to the wastegate actuator arm) for ease of installing/removing the downpipe. I really should take more pictures of my setup and actually do a build thread, but I'm a bit on the lazy side.

I'm more than happy to answer any questions though, good luck with everything!

yes a picture would really help a lot in seeing how you've clocked the turbo. The other question I had was, the coolant lines on the turbo seem to be too big for the lines in the car. What did you use for those?

Looks like the downpipe is the only thing remaining in the puzzle right now. I'll update this thread as I build.

Bigger injectors went in today. I'm surprised at how much smoother the idle is with these than the stock 205's. No doubt the stock ones were clogged or something, cause my idle is much richer even with a REQ_FUEL change in the ECU.



Time for some proper tuning with these so I can get the NA part of the map dialed in. Helps that the weather is quite brilliant today.

VE map and AE are fully dialed in, and I am getting OEM driveability too. The car idles and runs just like stock, with better throttle response everywhere in the rev range.

Some more inexpensive parts (thanks miataspeed1point6):




That's a probe intercooler and the pipes-that-may-not-be-named.

Yeah, cheap, but I think its perfect for my needs.

My EGT gauge with 0-5V analog output to the MS. I can log EGT with this thing. All for less than $90 shipped. I'll let you guys know how well it works. I'm guessing the enclosed thermocouple is not fast enough:

I'm guessing that gauge controller has this circuit built into it? http://www.msextra.com/manuals/MS_Ex...Manual.htm#egt

Attached are some pictures of my setup. You'll see that I utilized the stock oil drain pipe, but had to get rid of the stock coolant lines (or you could use a hacksaw and attempt to make them work I guess...). I have both PS and A/C so you'll see how I put everything together.

Partly correct. All the circuit does is to amplify the millivolt output of the thermocouple into a 0-5V proportional output. The unit I have gives the exact same signal with the added advantage of being able to act as a gauge.

Thanks karter74 for the pics. I see you've clocked the coldside separately from the CHRA and the turbine side. Is that a custom wastegate actuator bracket?

I'm planning to clock it like the stock greddy setup (ie compressor outlet pointing straight towards where the OE AFM sits), because I imagine that's the easiest way to make it fit with the Jim pipes.

That's pretty cool, where'd you get it if you don't mind sharing?

Sure, its an obsolete unit now, but the manufacturer makes a newer one. Here it is:

This one can also light up an LED or buzzer when the measured parameter goes beyond user-specified limit.

I'm going to get this thermocouple since it has an exposed junction:

Should give me the latency required.

Is it a good idea to have a 5.1V zener in the EGT input of the MS just in case?
