how can i tell if a turbo if a vnt or not.?
are ALL diesel vehicles nowadays fitted with vnt's.?
or are there any diesel vehicles with std turbo units [not vnt's] fitted?
im always on the look for bargains so im just wanting to expand what i can look for.
was sent this link by emma- http://www.turbo-product.com/index.asp
but nothing tells me if a turbo unit is a vnt or not?.
Vauxhall,Ford and Renault use Garrett Turbo's on their deisel models. Just try and avoid the Chinese copies.

on a vnt the actuator is set between the two housings rather than across the housings like a normal turbo
I think Garrett stick a V in the name Raj
Look for the vane adjustment grub screw and as said previously the actuator will be between the compressor and ex housing
And No not all diesel nowadays have got a VNT fitted.

thanks,
i suppose its now just a case of knowing what cars that have turbos fitted with the same/similar shape housing as the gtt for less faffing about, ie tomcat, 200sx s14?,....
no such animal, they will all need dicking with
i thought with the tomcat its just a case of turning the housing and tapping it for the actuator? and blanking the dumpvalve outlet off??
unsure about the 200sx s13/14?? although it does look like it'll match up well??
ahh, so you're looking for a turbo without VNT then, in that case, as you were...
are there any mods needed to bolt a t28 to the gtt manifold.? im sure ive heard the 4 bolt holes are spaced further apart???
im assuming that an oil feed adaptor is required aswell as a different size oil return hose maybe?
a T28 should bolt directly to the manifold, it's the elbow that may be a bit iffy.
its a got a t3 flange whatever that means??
Yes, which means it's physically bigger, and won't fit.
wont using a t2 to t3 type one of these adaptors work.?
yeah, as long as the extra length won't push the turbo through the inner wing.
but what's this T28 with a T3 flange? Are you sure it isn't just a T3?
its off an r33 gts skyline. its a std unit and has nissan cast on the comp housing.
They're some weird T3 rollerbearing as standard, if it's an import model, with a plastic compressor wheel, iirc.
