Typically 36-38 psi. R32 GTSt with stock arms, urethane camber bushes F&R, ball-end caster rods, sensible sporty street alignment, Bilstein@F & KYB@R + Kings springs, 24mm adjustable F&R. Spot on legal ride height.

Some of that has changed this month - new SK B6s F&R, GTR Kings Springs F&R. Not using KU36s atm having bought some Goodyears for almost nothing from Tirerack some months ago.

FWIW, the new dampers and springs have changed my car so much that I have more grip now on the lesser Goodyears than I did on KU36s, and if I were to put KU36s back on I would either have massive grip or I'd wear them out in 3 weeks (or both!).

Or break a gearbox? :)

Hahaha, yeah my mate has one. Im quite astonished at what they put down.

And honestly the ones at the drag strip scare me (im in WA so all the mining guys love em and throw mad money into their LS's). If its lumpy its usually in the 11's :(

      RB25 S2 Idles but doesn't want to rev

      By Trilbyte · Posted

      No intention of driving the car the way it's set up now, just wanting to make sure I haven't made any mistakes along the way so that the tune can go smoothly, I don't want to waste anyone's time with stupid issues. And of course I intend to get it towed to the dyno in a completed state 😅 I have the base fuel pressure with the vacuum disconnected set at about 40psi, which I believe is at least relatively close to stock fuel pressure, maybe I'll have a fiddle with the reg and see what happens. For all I know I could be wasting my time with this and I should just plumb it in and see what the tuner reckons. I just find it a bit strange that it seems to be under so much load just free revving, but maybe that's just a result of the turbo slowing down the exhaust gasses and making a restriction in the flow, with no boost to compensate.

      The boy just hit up google translate and it worked a treat, he said step one was "please urinate with precision and elegance", he then sent me the correct translation  I get some new loctite for the small fixtures tomorrow and get some "dort" going after that 🤣

      Right, so is the fuel pressure the same as it was previously? If not, well, it's not going to work well. I can understand the theory I assume you are going for, which is: "Run it N/A, and if I have the original AFM, and same amount of fuel and intake air as previously, the fact there's a turbo in my exhaust should still make it run" Which it... might? Provided you don't actually change how much air or fuel is going into the car.. or getting out. But if you have changed that, all bets are off. What is the purpose to even have the car run this way? To get it to a tuner? And if the goal is to limp it to a tuner, you're still going to what - plumb up a whole intercooler system and new intake in the parking lot out front before your tune......?

      Haha yea it's a bit of a weird setup at the moment, just wanted to make sure I sorted out any headaches before dyno day. At the moment I've changed the exhaust manifold, turbo and downpipe, 460lph fuel pump and rising rate reg as well as the previously mentioned headstuds and gasket. The nistune was already mapped for the car as it was and drove around for a few months no worries. The plan is to run flex fuel hence the big pump, which I've wired direct to the battery through a relay to avoid voltage issues.

      Um. Was the ECU the same as the one previously there? I know R33's needed R32 GTST ECU's or other tomfoolery to run Nistune. This is such a wild setup. Most people would plumb in the turbo then not drive the car (i.e tow it to a tuner). What's actually changed since it last ran?
