Hi Guys,
Its been a long time since I have posted.
My car is a 2005 MY06 Liberty GT Tuned by STi Auto with the VF38 - Preface Lift
Quite a few years ago the VF38 died and had GCG Turbo recore and machine out the VF38 housing to accept a VF34 core. I have been reasonably happy with the results the car making around 180awKW. So that was what I considered Revision 1 upgrade, considering the constraints around the preface lift autos.
The car has had custom CES Dump Pipe/ Exhaust; Tomei Spec C Twin Scroll Headers(reduced down inlets to fit VF38 flange), and an MRT Cross Flow intercooler; ultimately the turbo is the restriction as shown on the dyno.
Lately I have been tracking an oil leak and it appears its the turbo; whilst I could probably have it refurbished again the turbo has to come out regardless so I would rather replace it with an upgraded unit.
I am prepared to redo the dump pipe and also the headers (they are already aftermarket). I have looked at aftermarket options, including IHI VF36/VF42 turbos and I have a concern about the orientation of the compressor charge outlet. On the VF38 the compressor charge outlet and the turbine exhaust inlet is facing north/south; the compressor charge outlet flows north to the MRT intercooler.
On all the aftermarket turbo pictures I have seen online including the VF36 the Compressor Charge flows East; which doesn't align with the MRT intercooler. I realise you can probably rotate the compressor housing so that the compressor charge outlet points up, but I am concerned the wastegate actuator will foul or may not line up wiht the turbine exhaust housing? The wastegate actuator has to attach to the turbo somehow and line up.
Can anyone provide some advice on this please? Has anyone fitted a VF36/VF42 before to an Auto Preface Lift? As I indicated I am not concerned about recutting and doing the dump pipes or the headers; just need to understand which turbo is most suitable regarding fitment and how to do it.
I have been looking at the Blouch Dominator XTR 1.5 Twin Scroll but I get the impression they are really designed for Post Facelift Legacy GT's not the JDM Spec Liberty's so am excluding this as an option??
I have included a picture of a turbo to assist.
Thanks,
Enver
