Hi all,

Can anyone comment on whether an IHI VF32 turbocharger out of a Lagacy would make a good upgrade/swap for the standard TD04 providing a remap is done.

I can't find any info on it.

Thanks.

 

VF32 TB, PZ?? ex.h/46.5mm c.h/10b c.w/0.70 A/R - Legacy/B4 Secondary turbo
VF33 TB, PZ11 ex.h/46.5mm c.h/6+6b c.w/0.75 A/R - Legacy/B4 Primary turbo


TB = Thrust bearing/Plain Sleeve bearing
ex.h = Exhaust housing
c.h = Compressor housing
(x)b = (x) bladed compressor wheel
c.w = Compressor wheel
A/R = Area to Radius turbine housing ratio

 

No a Vf32 would be no good for anything but fitting in a legacy twin turbo.

You'll notice that a vf32 turbo doesn't have a wastegate fitted

 

I was wondering the same thing would have to get some pipework made up and run it externally gated :S pain in the butt shame cuse they go for nothing

 

The turbo is not good enough to go to all that trouble. I reckon it's only marginally better than a td04

 

If you where to use it. You could probably fit an exhaust housing from a similar ihi waste gated turbo which would be easier than going external.

 

I just checked on my vf27 turbo which is about the same size as a vf32 turbo. I compared the size to a td04 and a vf24. The vf27 is considerably smalle than even the td04.

Therefore don't bother even thinking about using a vf27 or vf32 turbo on an impreza. Only useful on the legacy as originally fitted.
