MY04 Liberty GT - FrankenStien - EOI welcome / FS

Thanks mate

Took a bit of massaging the rear quarters but keep in mind my front and rear guards / quarters have been previously rolled and pulled.

A little mexiflush in the front (just a touch) but I can't go any lower til I fix the driveway in the new house otherwise it won't make it in.

No scrubbing whatsoever - clears brembos by 2mm without spacers so happy with that

Some may not like the stretched tyre fitment but in all honesty the 235 40 18 Zetums (kumhos) are not that badly stretched IMO

Looks schmick Mick!

[Boostaddict]

Shitty pics..... are shitty.

Naaa brah looks sick.

Gotta come have a look one day

When i have a car that works

So maybe NEVER. LOL

[dr20t]

Thanks mick

Dan you're right they are shitty. Need to do a proper photo shoot - calling Jack !

Come past whenever man.

Love them!
Was looking at the same wheels for my car in 19x8.5.

[dr20t]

Thanks Adam

Yeah when I bought them 2 years ago I wanted to go 19x9.5 but they only came in a 43 offset which wouldn't clear my brembos - spewing about that.

[peadya100]

It's so hard to find 19s these days (other than tempe).. I can't imagine having to worry about brake clearance as well. Finding wheels is the hardest and most heart braking thing I've done in a long time hahaha

I don't think you needed 19s anyway. They look just right!

[dr20t]

Yep. I've got four sets of wheels / tyres at home for the lib and three for the gemi

Thanks for the kind words. Gotta say I've had no negatives with the slight stretch either.

I threw out my 235s and imported a set of Advan 245s. I personally can't deal with the stretch and having to run close to 40 psi. Get some more camber happening bro!

Or do what owen does and eats more Dumplings so the extra weight gives extra camber!

[dr20t]

Yeah I'm not too fussed with the stretched 235. Actualy rides better than with the 235's on the 8" rims.

Front camber needs to be dialed in and will naturally camber more once ride height comes down a little

So - after almost 3 years with this setup, and countless diagnosis, fixes, changes and attempts at tracking this pre turbo exhaust leak / lean spike / slow spool / stuttering at transition from vacuum to boost - I have found the problem.

This is after no less than 10 times removing and refitting the turbo, headers, gaskets, wastegate, etc etc.

I have literally changed all the following multiple times:

Headers
Welded uppipe
3 bolt gasket (have used 5 different gaskets including 3 x grimmspeed 7 later mls gasket)
Header to manifold gaskets (3 sets)
Subaru turbo flange gaskets (3 sets)
Welded the slip joints, welded the egt bung up
Wrapped the headers
Machined all surfaces on 2 different sets of headers
Changing turbo housings
And several other things I can't even remember now

Yesterday I had the 3 bolt uppipe flange replaced with a stainless, stepper v band. At the same time, I also had the Subaru flange at the top of the uppipe changed to a v band (with corresponding v band on bottom of twist mount adapter).

I'm happy to say this has eliminated 70% of the pre turbo boost leak and made the car MUCH more enjoyable to drive on the street.

However - it still has the flutter / exhaust rattle on transition from vacuum to boost. Its less of an impact now thanks to fixing all other preturbo exhaust leaks, but its there nonetheless, and still annoying me and affecting my ability to build boost on the brakes unless the headers / turbo are very hot.

Good news is rwe have now isolated the slight boost leak to the tial mvs. A google search will show you that the tial mvs wastegates are designed to leak from factory. Ordinarily this wouldn't be a problem, however for my car it is for two reasons;

1. Relatively medium sized turbo for a 2 litre with very long header piping (thanks Subaru for the f you)
2. Maf setup with large fmic to throttle body intake piping, meaning any slight vacuum leak out the exhaust is causing issues.

I also have a suspicion the fire-ring in this particular wastegate is not sealing 100%. I will first change the fire ring to a nee one to isolate it, then will change springs in case the springs are duds.

The car has been making this sound / exhibiting this behavior since the first day I've had this turbo / wastegate setup on. I remember driving out of g88 and hearing the sound before the car was even tuned. When I came back and told Michael he too (like me) believed it must be something hitting the gearbox or xmember / swaybar. Ie - a physical rattle.

This has since been proven false, and now the final thing to change is the wastegate to verify.

In saying that, I am alot happier to drive it on the street than ever before after fixing the uppipe leaks.

Will keep this thread updated with outcomes.

So glad to hear that Mick. Always brings a smile when the car is driving better. Any reason in particular you didn't go V band's to start with? I've only ever heard good things about them. S&J told me to stick well clear of any 3 bolt flanges due to leaking.

Happy days ahead
