hrmm thats interesting..

When I had the VG30BB turbo down at Bills he said the comp wheel is slightly smaller than the rb25.

Mine didn't directly bolt up as the 3bolt flange was a slightly different size.

I ended up using the std. vg30det with a 90degree piece of mandrel, then silicon hose to attach the 90degree bend to the compressor outlet.

This was 2+ years ago now so maybe bill had his wires crossed.

You had your turbo done at Bills after I had mine in so maybe he then realised when playing with it. I only had mine in for an inspection as I had trouble getting a decent vg30det turbo, 2 had bearing problems and the third had a real slight squeel when up over 13psi.

Is it bush bearing or bb high flow?

i was qouted $1950 to high flow with new bal bearings. GCG said that they can do for about $1200, but it's a bush bearing instead!  :flamed:

Ball bearing, I was quoted $1950 as well, final cost was $1169.40. BUT they didn't have to convert from bush ==> bearing, mine was already ball. I can scan and post up the invoice if required.

I was stoked, $1200 is cheap for the type of performance I expect to get, I can drive it now [it will benefit from a tune, but all in good time].

He got a good deal then..

Over here in SA there is a bloke who does a pretty mean internal gate turbo.

I think it runs a GT35 core and has made to date around 270-280rwkw on 17psi of boost on a stock rb25 + supporting mods.

BUT that turbo costs close to 3k.. In this case you get what you pay for.

      Thanks heaps Duncan and GTSBoy. I'll get my old man to sit in the driver's seat and turn it on and off while I test with the meter. Or maybe other way round, depending on whether he remembers where his glasses got to

      This is the GTR fuel pump. Yellow shows 12V, orange shows earth. The ECU provides the earth to activate the fuel pump relay. The ECU side of teh relay will pull low when the ECU activates. This is the RB20 fuel pump. Almost the same, but a little simpler. You can see I indicated (above) where the 12V line goes down to the RB20 diagram on the overall diagram, whch shows both RB26 and RB20. This is where I show it coming in on the RB20 diagram below. You can see that the dropping resistor is handled differently. When the fuel pump control is not providing earth to the pump, the pump earths through the dropping resistor and thus runs at lower voltage (some is wasted over the resistor) and runs slower. I showed that "not 12V and not quite earth" portion of the wiring in a paler orange. The rest of the wiring that I did not colour on that little section below the pump would be orange when the fuel pump coontroller is providing earth. This drop is handled inside the fuel pump controller in the GTR. Regardless, you can see where 12V is supposed to be, where earth is supposed to be. The key on prime is via the ECU providing the pump for only a few seconds the switching off. You should be able to see that happen.
