HKS GT SS vs 2530's vs Trust T517Z's

[Merli]

Can I please just say that they're not "t51's"... They're "T517z"....

It's kinda like saying I'm buying some HKS GT253's for my car :Oops:

Yeh first time i read...

Anyone gone from GTSS's to T51's ????

I scratched my head and giggled i hope they are at least Kai versions...then it was like, oh yeh you mean T517z

[Sydneykid]

I agree with Roy, most of the dead turbos we see have turbine and/or compressor damage. Very few have core damage and most of those are plain bearing cores.

It's a self fullfilling prophecy.............

plain bearings cores need rebuilding more often

so

they are cheaper to rebuild.

The most tricky bit is their wastegates open the other way, this makes using the common designs of split dumps almost impossible.

They work fine with HKS dump pipes, and Trust also make split dumps......

[GTR R32]

Yes, translated for those in metric land 278 KW's !... and watch this space, more to come yet !

jezzrrr, my car is currently making almost the same power (273 rwkw) with standard turbos. I reckon there will be more to come as well

[Ad_N]

I have Trust T517z's on my 32 GTR. They are a little laggy but when they come on (around 3800 - 3900 rpm) they are on to stay. A set of cams and cam gears, get it on boost a little earlier and no worries. Most of you may think this a little silly but 342kw on 24psi, at the rear wheels on stock internals I feel is not a bad effort. The only hickup which has just recently happened after about 1 1/2 years of running these turbos is 1 of the air flow meters let go.

Time to upgrade to z32's. For those of you who are interested the upgrades to date are the following:

Power FC

AVCR

HKS Fuel Pump

HKS 680cc Injectors

Turbosmart Fuel Reg

Apexi Pod Filters

Trust T517z's (8cm Housings)

Twin stainless split dumps

Nismo Exhaust

Trust FMC

plus the usual gauges, seats, steering wheel, rims, suspension upgrades etc. Mods to follow in the very near future are Z32 AFM's, Splitfire coil packs, cams and cam gears. Then start saving again for rebuilt motor.

[Billet Ricky]

As a point of interest Billet Turbochargers can convert the Trust T517z's to a Billet ball bearing core

lol 5 year old thread!!!

lol 5 year old thread!!!

yes but considering T517Z's are $1000 on ebay brand new, it's something to look at $ wise.

iv'e owned stock GTR turbo's and won't voluntarily again.

digging up old threads

Least people are searching though

[Owgasm]

So are the t517z below GTSS and 2530s?

Also, do they fit on standard dumps and manifolds?

[Nee-san]

no no and i think so better confirm though.

[Nee-san]

wait which version you mean ?

No T517z are in the middle, depending on housing choice will dictate how far to which side of "middle".

To note they are bush bearing, and I've seen JAGR33's car go from 517's to -5s

Same power, better response all over.

There is a 517 graph on the the "dyno comparo" i posted a few months back.

[Owgasm]

Nismoid, how do I work out which housing the t517zs I'm looking at have?

What do I measure?

Would the 8cm or 10cm be better for a stock internal rb26?

[D_Stirls]

Blue32 made 427kw with T517z's (8cm2) on PULP and is making over 450kw (actual power not known as the tyres are spinning on the dyno) on E85.

Go the 8cm, less lag. The 10cm would suit a 30 bottom end....

[JAGR33]

T517z's will make big power, but the -5's are much better for response....

There is no way your going to get a new trust T517Z kit for $1k....

I have 10cm's... but I'd suggest 8's for street work and/or stock engine.

Yeah right...

I nosed over 400rwkw with my 10cm's.... and that was pushing them as hard as they would go. An honest 430rwkw on 8cm's..... hmm
