Just having a few problems with the oil and coolant lines on the VG30 due to the extra deck height but i guess that all the fun, will hopefully have it in the car and running sometime this xmas holidays!

Just thought I would bump this 20 year old thread because the Skid Factory have just posted up a video summarising a lot of the content, format might be more familiar for newer members

The cams have 9.0mm lift direct fits probably a bit of overkill for the rb20 but when everything comes on together is a good hit, should be nice in the RB30.

Where did you get your CP pistons from?

TweakIt at Mona Vale, Sydney.

They're doing the build for me.

Platinum,

We will have to take eath other for a spin with once yours is in and running. :)

I'm keen to see the difference a higher diff ratio makes, I'm sure your also keen to see how mine drives with the 4.363:1, by the time you see it she will most probably have a 4.11 GTR mech shimmed center.

The VL being roughly the same weight as the R32 and the gearbox's having very similar ratio's it should be quite a decent comparison. :(

yeah no probs sounds like a plan. Just got to get this thing installed over the holidays, I seriously have no idea how the fark I'm going to hook this plenum up, I barely just had the VL one understood, this is like 50x more difficult. :)

Martin Donnan hasn't had much luck with the RX7 squirters and the stock ecu. Bad idle.

Resistor pack isn't a hassle. R30 resistor pack ~6ohms, I've seen them as low as $5 (when they don't know what it is) and up to ~$30.

Works perfectly. :D

The RX7 injectors appear to work quite well with the PFC and the RB30DET.

Nice smooth idle and nice starting also.

      I was wondering about this. I'll do some research.

      Why not? Since mines been built, I've used low boost maybe 5 times.

      gauge needle removal

      By GTSBoy · Posted

      Yeah, so widen your search to any Nissan speedo first, then go wider if needed. I will say though, that there is a better than even chance that what I said first will likely come into play. They quite possibly won't come apart without damage. I tried to disassemble a stepper gauge that I wanted to repair. There was no way that needle was coming off the spindle, and I could not see how the spindle would come out of the mechanism behind. Assembled once, never to be disassembled, was my conclusion. Could be the same on the R34 cluster. Failing that - take the cluster to a workshop that specialises in automotive instrument work. There's usually at least one in every Australian city. They'll either be able to do it for you for small cost, or tell you it can't be done. It might be that "it can't be done" unless you follow some arcane procedure, including trickiness to glue it back together or something, that only experienced techs know.

      R-chassis INNER tie rod torque spec?

      By GTSBoy · Posted

      Well, given that I, an engineer, almost never bring out the torque wrench to tighten up chassis bolts, despite fully knowing the theory, and instead rely on feel, which I happen to know is exactly how the majority of mechanics do things, should tell you the level of actual peril that exists from not achieving exactly 88 Nm of torque. How about if I just say then that 88Nm is at the lower end of the correct wheel nut torque range? Everyone knows how to tighten a wheel nut, right? And almost no-one ever brings out the torque wrench for that task

      Don't be ridiculous. "2-3 ugga duggas or one Oof. You have to use Oof on tie rods because you can't get an ugga dugga on there." Is not helping the guy at all.
