So,

I've been rather quiet lately. To say the least I've changed jobs, been there 3 months now, and have been trying to make ends meet, even though they keep moving themselves.

I've kinda neglected my car and its ongoing mod upgrades.. But rest assured, I have done some more changes.

I think this first picture will explain where its started..

Oh noes! its gone!

But I'm sure this can fit!

With the last picture, You can see, this is where we dummy'd up the turbo into position before making the extractors.

All the Fabrication work was preformed by a good mate of mine, Jason. He has a 9 second LPG powered XE, and is known as "GASMAN".

Another angle.

Hrm... Or do we use a T51R instead of the 42?

Here you can see Jason has completed 4 of the 6 runners. All spot welded into place.

Setup on a dummy engine with the 4" dump and external gate

Back into the engine bay..

The beauty thing about how Jason works is how fast he does things. Friday night is where I removed the standard turbo setup. We dummy's up the GT42's position, and I left the rest with Jason. The extractors were completely welded by the end of Sunday night. He didnt really get much work done on them Saturday night, Plus I was at a wedding getting Sloshed. The Monday and Tuesday, the Dump pipe was being made and the external gate fitted. Everything was ready to drive out Tuesday evening, But I purchased the wrong dash6 fitting for the turbo, a 90 instead of a 45. So It was done Wednesday.

Now in terms of tuning. The engine is still the standard engine. I haven't altered the tune at this point, But I did run it up on the dyno to see whats going on. 22psi, 380rwkw, and 12.5:1 afr's... Yep, no typo's there. At least there was no detonation.. The 22psi of boost was straight off the gate, so surprisingly to Jason, we had a boost creep issue. Since then we've removed the extractors, and altered the wastegate entry pipe, and how it feeds to the wastegate. Got much more controlled boost now :D

To come.. Engine build photos (I wont post them until its completely done).

stock bottom end...380rwkw...22psi... great tuner there ey! Nice work as always.

It actually made 398.6rwkw previously with 17-18psi with the standard turbo. In my tune, I have another load site above the desired load/boost which rapes the timing in the event of a over boost. Essentially 22psi is over boosting compared to the previous 18psi.. So quite frankly, I was quite surprised that it made the power it did with barely any timing.
