Hi all.

Well I have noticed a couple of people show interest in the RX6 turbo lately. I am lucky to have 3 in my hands atm.
2 of them are the smaller one in the picture and I have one that is significantly larger.
I have been researching these turbo's for a while, and through my connections I have been able to gather genuine tech info form these personally and also through retail sale agents.

Below all the info is a heap of pictures to show the difference between the two turbos.

So here goes, the first one I will put up info about is the smaller of the two.

The tech info on the turbo with the plate with spec number VA490030 9607

Compressor
inductor 52mm
exducer 78mm

Turbine
Wheel diameter 62mm
Trim P16

A/R still awaiting info from suppler

HP 390 to 440 on a 2 ltr engine


Turbo with the plate with spec number VA490032 9807

Compressor
Ind 52mm
Exd 82mm

Turbine
Wheel diameter 64mm
Trim P18

A/R Still waiting info

HP 450 to 550 on a 2 ltr

As I find out more about these turbos and dyno sheets I'll post them up.

This is the small one










Lets compair the two





Now the big one

I don't understand the point of this post are you trying to advertise your product/ sell them or just babble on about them?

Well I've got no idea if you have came across these turbo's before. But any tech info is extreamly hard to find.

The reason why I have posted it is for people's FYI if they do come across they know what they are.

You can almost work out the a/r yourself.

Measure the cross sectional area of the turbine inlet. Dont measure at the flange, but at the point where the turbine 'starts'. (i.e, run you finger along th einside of the turbine entry until you feel sharp edge that exposes the turbine wheel tips)

Lets say at this point, cross sectional area of the inlet is 900mm2. (9 cm2) A fair bit bigger than a 50c piece. This would be 'A'
While you're there, note the centre point of the cross sectional area.


Measure the distance from the turbine wheel centreline to the centre of the cross sectional area above. Lets say its 1400mm (14cm). And this would be the radius of the turbine entry from the centre of the turbine wheel. This is 'R'

Divide A (900) by R (1400) = ~.64




A/R = .64
