I'm in a bit of a bind. I had a genuine T67-25g kit including stainless manifold and 48mm ext gate which I bought for a build up on an RB25DE+t which I intend to run on E85 using a Haltech PS2000. The T67 was stolen from my garage. So I have a manifold with a trust flange and no trust turbo. Given that new trust turbos are well outside my budget and 10cm exhaust housing second hand units seem to be extremely rare, I was looking down the tried and tested Kando (kinugawa) path.

Kinugawa only sell trust flanges in 8cm and 12cm exhaust housings. I'm fairly sure 8cm would be too restrictive for what i'm building but I note a few people have used the 12cm on RB30s. Am I crazy to consider buying one of these?

Really appreciate any advice at the moment as i'm really not turbo savvy.

Sad face :( no thoughts? I've seen some 350rwkw on E85 out of the 8cm housing from Trust, this is where I was aiming in power anyway so that is looking like better candidate than the 12cm now.

Well the high comp engine does not help with back pressure and heat. Using a large 25G comp with a small L2 turbine in a tinny 8cm housing is going to make your engine pin and significantly reduce the life of the turbocharger. If it has to be a Greddy style of a turbocharger I recommend the 25G with a TD06H turbine in a 10cm housing which you can get them separate and we can machine it to suit.

Alternatively you can use one of our .82 turbine ended SS2 in .70 comp as an high mount. which is very reliable and will produces excellent turbo response while make the same amount of power as to a 25G compressor.

      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.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
