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.

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 http://tbn0.google.com/images?q=tbn:vN0ATsR5BwR-7M:http://techon.nikkeibp.co.jp/english/NEWS_EN/20080222/147866/07.jpg (http://images.google.co.uk/imgres?imgurl=http://techon.nikkeibp.co.jp/english/NEWS_EN/20080222/147866/07.jpg&imgrefurl=http://mercedesshop.com/shopforum/showthread.php%3Ft%3D220317&h=645&w=860&sz=40&hl=en&start=9&um=1&usg=__bXJ1mOG7m0_8WoJ9IV6zpVYs_oo=&tbnid=vN0ATsR5BwR-7M:&tbnh=109&tbnw=145&prev=/images%3Fq%3Dvnt%2Bturbo%26um%3D1%26hl%3Den%26sa%3 DN)

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??

[Andrew Cooke]

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??:confused: is the flange the part that blots to the manifold?

[Adam L]

Yes, which means it's physically bigger, and won't fit.

wont using a t2 to t3 type one of these adaptors (http://cgi.ebay.co.uk/T25-TO-T3-TURBO-FLANGE-ADAPTER-OR-T3-TO-T2_W0QQitemZ400001229310QQcmdZViewItem?hash=item40 0001229310&_trksid=p3286.m63.l1177) 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.
