Extrude Honing/power Porting , Where ?

[discopotato03]

I am looking at having a turbine housing extrude honed and need some recommendations on where .

From a sniff around Specialised Power Porting at St Helen in Victoria looks popular .

Has anyone used them and were you satisfied with the result you got ?

Cheers and thanks , Adrian .

I don't think it's such a good idea to get a turbine housing extrude honed. You will disturb the wheel/housing clearance and the turbo will become unresponsive.

Then again, if you know what you are doing, Specialised Power Porting are, I think, one of the only ones who do it

Kyle from 6boost recommended those guys to me, so they must be pretty good at what they do.

havn't had anything done by them yet tho.

I've had inlet and exhaust manifolds and a compressor cover done by SPP. Due to a change in the setup I never used either of these components but I have before and after flow figures for the manifolds. There is no change in clearances with the comp cover - because none of the machined surfaces are touched - only the volute is done.

Also SPP doesn't do twin scroll ex housings.

im intrested in doing this on a gt-rs what prices are we talking about and juggernaut where you happy with the results?

You'd have to call Andrew at SPP for prices as it was a while ago when I got mine done.

As stated in my previous post I never used the extrude honed parts from SPP as I changed my setup and sold the parts off.

Although had my new twin scroll ex housing setup extrude honed in the US (SPP does not do twin scroll housings)....C-Red is just finalising at the moment.
