What power level would usually warrant going to a 4" exhaust (4" all the way from a single turbo setup)?

Bump

Regarding the pen marking on the back, this is actually from the factory! I have an R34 turbo with a similar code written on it, with the same pen. Looks like the same handwriting too I have found a few parts on the car with similar handwritten codes, including the gearbox.

New Kinugawa wastegate actuator to suit Garrett GT30 series turbos with an a/r 60 front cover. Adjustable and includes all optional boost pressure springs - 0.5, 0.8, 1.0, 1.2 and 1.5 bar. Very solid billet construction and top can be rotated to suit requirements. Also has a second boost reference port, if required. $95 including delivery within Australia. Cheers Justin

This attached brochure (third last page) says the manuals were helical and the auto's viscous. That being said, perhaps the NZ imports were all specified with the helical diffs. R34GTT-Brochure.pdf

I always thought all R34 GT-T manuals (series 1 and 2) came with the helical torsen diff, and the auto's came with the VLSD's?

Actually thinking about it, the cold start valve will always be open given no coolant will be going through it to close it when warm. Hopefully I can just turn down the IAC valve screw to compensate.

Thread revival! I'm not going to plumb my cold start valve to the coolant lines on my Neo engine. AAC valve will remain however. 1) Will the idle during a cold start be much of an issue? I live in a reasonably warm climate for most of the year. 2) Given the ACC valve is just a solenoid valve, would it be worth me wiring it up a separate controller that triggers it when the coolant temp is > x? The car has no a/c so I figure the AAC wont be used much by accessories in the car. I will be running a Link G4 ECU. Cheers Justin

Yes I have the receipt for the full turbo kit somewhere, I will find it. I paid just under $3k for the kit. Then extra to get the dump pipe ceramic coated and to change the oil and water lines to braided lines. And yep, by OEM I mean the standard cast manifold. Cheers Justin

Complete kit with everything needed to fit an RB25, including: Garrett GTX3071R turbo Genuine Garrett 5 bolt 0.82 a/r rear housing, IWG Garrett 14psi wastegate actuator Spacer plate to fit to OEM exhaust manifold Turbo nuts and studs All water and oil lines (braided) All other required fittings - banjo bolts, crush washers etc. All required gaskets Compressor outlet silicon elbow Dump pipe to suit turbo (ceramic coated) $1950

It's just science, really.

R34 GT doesn't have an intercooler...

Buy this. Bolt it on. Skidz. http://www.sau.com.au/forums/topic/455358-new-garrett-gtx3071r-turbo-complete-kit-with-everything-needed-to-fit-to-an-rb25/

My R34 GTT project goals have changed, from fast / responsive street car to dedicated track car. As a result I'm now selling the new complete turbo kit I had originally bought for it. It includes: Garrett GTX3071R turbo Genuine Garrett 5 bolt 0.82 a/r rear housing, IWG Garrett 14psi wastegate actuator Spacer plate to fit to OEM exhaust manifold Turbo nuts and studs All water and oil lines (braided) All other required fittings - banjo bolts, crush washers etc. All required gaskets Compressor outlet silicon elbow Dump pipe to suit turbo, ceramic coated It comes with EVERYTHING needed to bolt straight up to an RB25. I bought the whole kit through Kudos Motorsports, and they obviously sourced it through GCG Turbos in Australia. I had test fitted the turbo to the exhaust manifold, but nothing has been run and the turbo is still as new. Fellow forum member Mick_o made a responsive 335rwkw from memory (on E85) with the same turbo in his R33. The whole kit cost me about $3k, and then I spent extra changing the oil and water lines to braided items and getting the dump pipe ceramic coated. I'm looking to get $2,100 for the whole kit, plus delivery. Cheers Justin

I'm going to have the same problem regarding the IAT sensor with WMI (if I ever finish putting my car together). I'm tempted to just run the IAT sensor downstream of the WMI nozzle and see what happens!

Yes that is correct, the plate is actually on the outside of the pump to seal it back up with the internals removed. The coolant still goes in through the (now empty) thermostat housing and through to that inlet on the front / passenger side of the block, like normal. The coolant then exits the engine / head via an outlet on the front of the plenum, pretty much like the stock setup. The only thing is the plenum does not have any other coolant inlet / outlets which is why I need to work out the best way to plumb in the turbo return / IAC valve plumbing. Actually I should have just posted a couple of pictures of it, would have been much easier! Will take some now. Cheers Justin
