After that I will leave the VVti on and up the boost 1 psi and tune until I am satisfied with the power end :)

Nice taking your time with it. I gonna try to get mine tuned tomorrow have to call around for the right price

Here are the latest updates of the engine bay.

- Complete Oil Custom Catch Tank
- Turbo Oil Pressure Gauge
- Added a 3 Gauge Interior Setup

Tuning is almost done. The only thing that remains is tuning on variable camshaft positions

For now I kept low boost (11psi) to verify that the engine holds easily up to 6500rpm. But I am feeling that off boost the engine can improve much more since the camshaft is rather retarded than advanced.

I didn't dyno the engine yet and didn't even try a track time so I cannot post any exact numbers. Also still need to install the much awaited NST crank pulley. The mechs are a bit busy lately so I have to wait for next 2 weekend for another update...

that looks nice.

So you have a separate oil pressure for just the turbo? That looks like a lot of adaptors stacked up! :)

Love that intake!

Everything looks so clean! I'm just wondering if it leaks.

For now it isn't leaking and I am not worrying that it would eventually.

Thanks for the comments

The idle problem was solved! Last night I dreamed that the idle motor of the 1NZ is the same like the 2ZZ and well it was infact!!!

The problem was the idle control motor not working for a reason now idles like a charm!

Dyno date is expected to be within about 3 weeks and I hope it will be the final tune! I am eagerly waiting for numbers!

Looks great! You've come a long way with this project. Cant wait to see the dyno numbers.

Yesterday I had my car started and noticed it was running different without changing the base map. Noticed the AFR showing stoich on all loads and rpm.

Done a free-air calibration and it could not get it calibrated. Checked with the manual and it is probably the sensor damaged.

The manual stats that for turbo charged engines the sensor must be mounted 12-16 inch from the turbine outlet. Could it be the issue?

Sensor was only used for 2 months.

What are your experiences?

Bluevitz-rs · 03-08-2011, 07:15 AM

It could be because it's too hot any closer than 12-16 inches. Was the reading changing at all?

Yoda · 03-08-2011, 11:46 AM

What kind of afr gauge you have? You can pull it out and test it.

Focus_Sh1ft · 03-08-2011, 01:10 PM

Check continuity maybe?

Yoda · 03-08-2011, 02:46 PM

i kno for my aem you can test it with some carb cleaner and a rag

Parmas · 03-08-2011, 05:02 PM

The sensor is connected directly to ecu and I can see the values on the Ecu software.

The sensor is Haltech, like the ecu and the reading change slightly from 14-15 on all loads and also when engine is off.

Bluevitz-rs · 03-09-2011, 09:04 AM

If it's still reading 14-15 with the engine off, either your software is clamping the sensor or it's gone bad.

Scubaru Steve · 03-10-2011, 11:59 AM

mine is 4-5 inches from my turbo in my wrx, its worked for 2 years, i believe i need a new sensor now.

as for the sensor reading when the car is off that is normal. the exhaust the piping is that afr, if you leave it on it should slowly slowly dissipate.
free air calibration requires you to remove the sensor from the down pipe in fresh air.

can always try replacing the sensor, i believe most use the 5 or 7 wire bosch. can get them at a decent price mostly.
