Hi all , I chased a link back to this site about someone having pics of this turbo . I have seen a turbo on a Isuzu Sitec engine thay may be similar/same . I can't get at its ID tag but this much I can see .

1.05 A/R turbine housing with extended 4 bolt outlet similar to non gated GT35R's .

0.65 A/R compressor housing with threads in the backplate washer / clamp plates instead of in the back of the comp housing .

No water cooling .

Up on top it has an internal waste gate actuator so possibly gated on one of the split housings inlets .

T3 flange .


Can anyone bring the pics back up from the thread late last year ?

ThanksAdrian .

 

No Sitec is a medium weight truck engine , late FTS series Isuzu . Someone on this board had a string on a GT3576 they had pics but pics not avail ATM .

These are interesting because they appear to use the GT35 UHP turbine like the GT3076R but with a GT bush bearing style shaft/core . Possibilities .

Cheers Adrian .

 

It also uses a 0.65 A/R compressor cover which is larger than any I know of for the GT37 family of compressors .

 

I have a gt3576 that i can take pics of if you still want some.

 

 

 

 

its from one of those goofy looking box trucks isnt it?

 

Yep thats the one ! Thank you . Could I possibly trouble you for some pics of it with the compressor cover off please ? Also the one I've seen (but can't get at) has an ID tag on the compressor back plate . A pic or the details would be very useful to me . A measurement of the comp covers inlet snout and the compressors OD in mm would confirm it uses a 76mm 52T GT37 series compressor wheel . Should measure ~ 76.2mm and 55mm exducer/inducer .

I noted that the turbine housing on your turbo has provision for a twinned integral wastegate but the holes were not bored or the dual flap valves fitted .

Just to satisfy anyones curiosity why I'm interested in some aspects of this turbo . Firstly the .65 A/R compressor housing because Garrett have only used .60 A/R housings with those 76mm GT compressors in the past - from what I've seen . I believe larger A/R comp covers can at times increase the choke flow at lowish pressure ratios (lowish meaning up to 1 bar) .
Secondly the turbine housing may have possibilities - divided housing with separate vent paths to maintain the pulse separation while ever the flat valves are closed .

Cheers and thanks , Adrian DPO3 .

 

I'll try to get those pics for you tommorrow.

 

lol, since when did the coke can become the standard unit of measurement??

 

thats the new metric coke can

 

got the numbers off of the tagthey read:

P/N 8-94390-6401
S/N DA 01 82J
GTI P/N 702173-1


hope that was what you were looking for.
I measured the diameter of the compressor wheel also it was 75 mm
Let me know what else you are looking for

 

Pics of the wheel side of the compressor housing and the wheel/backplate please .

Cheers A .

 

Pardon the thread Revival but i have this very same turbo only in a t4. Anyone else running this unit? If so, what power numbers is it producing?
