Need help identifying my turbo
« on: 13:52, Sun 09 August 2009 »
Just wondering if anyone could help me, I e-mailed turbo technics and no body has replied so thought I'd try you helpful chaps.

The turbo is from turbo technics and has a part number: 466506-1

Anyone have any idea what it is?

It doesn't have water cooling and strangely it doesn't boost very well when I try and set it low, will only boost properly when I set it to about 16psi or whatever the the standard boost gauge reads when the needle goes to the end of the red section!

Do I have a hybrid turbo or is the actuator fucked?

they probably didnt reply because the numbers dont mean alot you need to take measurements. ie the size of the housings and trims ect. the exhaust housing may have .49 or.47 on it for example but you would need to measure exhuast and compressor wheel to determain what exactly it is.

on the plenum where the two pipes from the actuator go one of the outlets has a reducer in it, swapped the two pipes over and the boost is now more adjustable and spins up fast :-)

as mentioned you would need to measure the size of the wheels really mate and see what size comp and exhaust housing you have to determain what it is.

Hi ,
the reference 466506-1 is the reference of turbo that was fitted on the engine of R11 Turbo from 1984 with 115 HP (so air cooled turbos ) . The Renault reference for this one are 7701351283 or 7701351281 .
There are a lot of chances that this turbo was fitted also on the GT phase 1 .
Hope this can help you .
Cheers.

It's got a funky rear housing in the pic looks like rear housing is held together by a circlip and not the normal bolt type

It's air cooled isn't it, not sure I can see any water pipes on it ??

You need to see what A/R numbers are on the front & rear & the size of the actual wheels to tell properly..

yes, it's held together by big circlips and it isn't water cooled.

I think the chances are it's a standard phase 1 T2.

Although, the engine was apparently rebuilt and it appears to have an uprated head gasket and head bolts so an uprated turbo would not be out of the question. I really need to remove it to be totally sure.

Bloody good eyes pal! Just been out and had a look and could just make out AR.35 and that's with the turbo in front of me! It was right in front of me all along.
