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.

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 :angry:

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

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
