I bought a VDO boost gauge and replaced my LC-1 and XD-16 wideband with the new digital MXT-L wideband. I made a panel and installed them in the glovebox.

I bought a ball valve to close off the heater circuit so that only cool coolant goes through the engine.

I also installed a crankcase breather / catch can.

Here is the final engine bay pic after completing the install. It starts spooling at 2300RPM and pulls hard. It is currently limited to 10PSI. I already spent 2 weeks street tuning it. Next step is to track test and tune.

The last part I have to install is the new undertray.

Here is the first start video.

After street tuning for two weeks and getting cold start, idle and basic WOT run AFRs tuned. I took the car to the local track (Arroyo Seco Raceway) for a test and tune. It was a bit rich at the top, so I leaned it out and all was well. The car ran great for the rest of the day.

Here is a video of one of the race sessions.

I have the Forge wastegate actuator with the softest spring (the green 5+ PSI spring) directly connected without the MBC and I still hit 10PSI around 6600 RPM. After the test and tune day at the track, I set the ECU to cut fuel at 175kpa (around 11PSI). I'm hoping that it will allow me to have a little more headroom to hit rev cut before overboost fuel cut.

I also plan to try a softer spring in the MBC to delay opening of the wastegate until around 6 - 7PSI. Due to the quick spool, it's probably unnecessary, but I'm curious to see what the change will be. I'd expect to overboost even more, but its easy to test it.

I tested my MBC and found that the bleed hole is too big to allow the wastegate actuator to open. I will reduce the size of the hole and test again.

looks good, any dyno graphs yet?

OK, bookmarking this as I'm going with ARTECH Manifold and full exhaust as well. I spoke with Abe and will probably pull the trigger on mine in two weeks. He talked me into the EFR too!

Now, I have to go back and read every post. Thanks for the cliff notes this is awesome.
