Garrett 2860r-7 Or T517z 8cm For Gtr

[arrow]

Hi guys,

I will be updating my standard turbos on my gtr. it will be a street/track day car and it will have all the usual mods cams, injectors, pump, air flow meters etc. Want around 330-350rwkw with the least amount of lag possible.

Have heard the t517z can make good numbers and is more responsive than the garrett turbs. I know that they are not ball bearing or water cooled, but is it a real problem?

Hard to find any results (using the 8cm turbs) with the trust turbo's not many people using them.

In the latest HPI mag it was said the T517Z will easily make 330rwkw on 1.3bar on a stocker. I dont think the garrett 2860 will make that power with the same boost and with more lag, correct me if im wrong.

So which is to be, let me know your opinions.

Also will the hks split dumps bolt onto the trust turbos?

Thanks guys.

Sorry I ment the garrett 2860R-5 (2530) equivalents.

I've seen a T517z I think with the smaller housing's run 370rwkw's on 1.8bar, engine was built, big cams ported heads etc...

Forgot to mention that on this engine they were laggy coming in at around 5,000 - 5,500rpm

Hello Arrow,

You need to read the RB26 Turbo Upgrade thread to increase your knowledge.

GT2530,s with Mods and supporting mods get you Approx. 310AWkw's which is around 360RWkw's.

This with no Engine upgrades.....just Tomei Pncams 260 with 9.15 lift.

I have then on mine with HKS Dumps and full spool is around 4500RPM.

These are the only turbo's you should consider for track-street performance.

They are rated at 350HP each.

I can get a price on these for you if you like.

Cheers

Tekin

PS .So answer to your question.....your statement is incorrect.

IMO for a street car the GT-SS is a better choice

But yeah, the 517's and 2860's are well covered and its really upto you to decide
