Great work matt. Sounds like its coming along nice.

Very nice Matt

Buuuutttt we need some pics!

Update time

New Torsen Front and upgraded Centre diffs I fitted while the gearbox was out have been performing flawlessly, the 2009+ WRX rear diff is going to be upgraded to a Torsen in February.
Entra Imports / Kartboy longer Hangers installed to drop the rear mufflers a little

Noticed my tune was running really rich, turns out it was the rear O2 sensor still unplugged and making it run rich as the CEL was turned off during my flex fuel testing. Took it up and down a windy mountain road with nothing over 3rd gear all weekend giving a good thrashing, still gets 14L/100Km(just over 400Km from a tank) on pump E85 and 8's on the highway

Pretty happy with the car as it is at the moment, maybe some new tyres and possibly a respray(wife wants a purple pearl over factory Newport Blue)

Nice work TH.

So having the rear O2 sensor removed/disabled does cause the car to run rich at idle and in closed loop, correct?

Disabled via AF Correction turned off with the 50/-50 values set to zero is fine for running right as the ECU ignores applying any corrections since it expects a catalytic converter of stock design. Reducing number of cats and/or changing their flow rate affects the rear O2 sensor influence on the tune
Having no feedback at all to the ECU results in richer mixtures. Adam@JEM noticed it as well on a car I was helping him with as he removed the rear O2 to put the dyno WB into the bung

It adds injection pulse everywhere, not just closed loop so 1.47 AFR points richer everywhere so 9.47:1 when 10.94 is target etc

For sale shortly:

ATP GTX2863R with 3" Perrin Inlet
Invidia Dump Pipe with STi steering knuckle
ID1000's

Plans are afoot... of the ATP V Band Twinscroll GTX3582R type...
Also, flipping the plastic intake manifold so the throttle is at the front near the alternator

WOOT WOOT...... That's more like it.

Can you flip the plastic manifold?? Didn't think you could.

[shav]

Will that dump and knuckle fit my car and if so, would you be willing to split that from the turbo?

[KiDo_Tuning]

Suce can Daniel, rather simple upgrade too!


Our engine bays are tight enough so fitting a GTX35 meant going under the car like my STi one(and a few other cars are going lately) but also means really short intercooler pipework!

It wont fit, will not clear the auto box

[shav]

oh well I'll order one from T-REXX instead.
Keen to hear how good the new turbo is matt.

So you have to do a custom header tank and move the maf sensor to the cold pipe before the throttle.

That pipe work looks longer then factory to. As the hot pipe goes all the way over the motor and down into the IC. It does make the cold pipe shorter but you loose that with the extra length of the hot pipe.

Wouldnt you be far better off going under like kiahatsu??

Love that reversed rotated setup! Link?
Low mount to vee mount to reversed inlet has got to be the ultimate IMHO

I am going under, turbo in the drivers guard where most CAI's fit and then into a FMIC and then back to throttle. 63cm total pipework. Turbo outlet V clamp will join directly onto the FMIC and it is just the pipework from cooler to throttle. As for the MAF sensor, I can use any CAI for the cold side pipework and with the MAF after the FMIC there is gains in doing that with intake air temps cooled by the FMIC so more consistent MAF values. I am only using the MAF for the cruise fuel economy as on boost it will be tuned off the Map sensor only.

Stock header tank in place on correct side is no issues although will need a new bracket. Photo is twist mount turbo so it did not fit.

Google flipped plastic intake manifold. I actually pulled my manifold off to confirm before I googled

I reckon on a GenV with a FMIC that this setup would be ideal!

[bigBADbenny]

Mmmm... foglight housing becomes compressor inlet

Crazy thread on nasioc featuring this setup in TS

Holy fuck that sounds sick.

When is this happening?? Who is doing the work.??

I want PICS and massive amounts of them.
