Advice please: VG30 vs Hi Flow

[Cubes]

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.

Yep the comp wheel is smaller, but the turbine(exhaust side has a ceramic 42mm inducer) which is identical to the Rb25.

The surge reduction groove in the rb25 inlet snout denotes the larger wheel.

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].

arent all R33 turbos ball bearing?

Anyone got a price on how much the RB 20 turbo is to hiflow - or is it easier to get a rb25 turbo

Its pretty standard..

Ball bearing you are looking at around 2k.

Bush and you are up for around 1k but add around 500rpm of extra lag.

But trident got his done, ball bearing, for $1200 :confused:

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.
