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.

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.

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.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
