TD05s on a 32 GTR? - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Totalburnout · 17th August 2005, 10:32 AM

Im looking at a R32 GTR which is running twin Trust TD05 turbos, does anyone have any opinions on this set up? Any ideas of the power etc?

thanks,

Andy.

Are they the Trust T517Z turbo's?

If they are I've got them on my car.

Totalburnout · 17th August 2005, 11:07 AM

Ive not had a close inspection but they are advertised as TD05s so i dont think they are the same ones mate.

td05 is an older trust kit.
Good for up to approx 650hp if 16g's, 700 if 18g's, 800 if 20g's.

16g is basically the same as lancer evo 1 turbo. But you have 2. : )

Totalburnout · 17th August 2005, 11:25 AM

Its a twin set up claiming around 600hp. So probably the 16g? Is this quite a good set up?
How does this compare to 2530s?

Andy,

I wouln't presume any size.

There is a tag on the centre bearing housing on most turbos that will identify them correctly. It can be hard to see on low mount turbos. Are these top mount? Any pics?

I would be concerned how long ago the engine was built and how much work it has done.

Take a close look at the oil pressure when it is being driven and note the RPM you get max pressure when it is hot and also what pressure you have at idle. It may have a high volume oil pump that can make a worn engine look good, but they usually have higher overall pressure.

Cheers

Hugh

Hugh, its the one Calder have in just now mate. Pics and spec on the site. Its a bit rough around the edges but the price would mean i would have around a grand left so i could tinker with it to my own spec.
Any feedback would be greatly welcomed.

Andy.

Is the TD05 bigger than the TD06 ?

Totalburnout · 17th August 2005, 03:01 PM

Might be smaller mate, but thats just a guess. Need to check the turbo/power graph on my comp at home.

kirbz · 17th August 2005, 03:53 PM

the td06 is bigger than the td05

the 16g, 18g and 20g turbos are old technology and spool up can be slow but they are a very well tried and tested turbo and they can make very nice numbers

John Mc · 17th August 2005, 04:33 PM

The Trust T517Z is a TD05 mitsubishi turbo, with competition wheel used by the rally teams on early evo's. It's just been reworked by Trust to fit a Skyline

Jay-R32 has the same turbo's and his car is running 537 at the hubs I think with hopefully more to come

I can post a Dyno graph of mine at 1 bar if you want mate. Mine don't hit full boost until around 4700rpm, I think having the cat still is strangling the performance quite a lot, but they pull very strong to the redline if I knew where it was

Jay's car also performs very well with these turbo's at 1.4 bar boost. His spools up quicker than mine though, bigger exhaust etc.

Hope this helps

Cheers

John

that would be a help, cheers mate.

John

Im also looking at a 33 with 517Zs, is there much difference between the power and lag associated with these two turbos?

Andy.

Hello mate not sure what you mean in the post before this one

Here is a dyno graph of mine at 1 bar boost

.

Hope this helps mate

Cheers

I was just wondering the difference in power and lag between the TD05s and the 517Zs? If any at all?
