THE RESULTS ARE IN!!!!!!

After driving my car around with 260rwkws (stock ecu/turbos) for three months, the hunger for more power was unbareable, so I went on the costly journey a lot of GTR owners decide to take....

My car has finally undergone the turbo upgrade, and after much deliberation decided to go for the Trust T517Z turbo kit. These turbos were chosen as everyone opts for the HKS 2530s, so I decided to be different and more importantly wanted to see the difference between the two, mainly POWER, RESPONSE, LAG...

These are the performance modifications undergone with the upgrade:

- Power FC

- Nismo AFM x2

- Trust Fuel Rail

- Trust 720cc Injectors

- SARD Fuel Pressure Regulator

- Trust T517Z 8cm2 turbos x2

- Bosch 044 Fuel Pump

- HKS EVC4 Boost Controller

- Custom Catch Can

- Daiken Exedy Twin Plate Clutch (converted to push type)

On the dyno the car pumped out 324 rwkws at 20psi (1.3bar). I was very happy with the result, but noticed that car was much laggier which was expected.... However when full boost hits (around 4800rpm), u can't help but smile!!!!!

In the next couple of weeks, there will be a comparison between my car and Simon's car (meshmesh) who has the exact modifications except HKS 2530 turbo kit.... The comparison will be done on the same dyno, same day....

Anyway heres the dyno sheet:

(NOTE: This was NOT done in 'SHOOTOUT MODE')

P.S Big thanx to Gerald and Nigel at Ice Performance!!!!!

And BIG THANX to Steve aka meggala!!!!!

intresting dude, thanx for posting, maybe try cam gears as well those turbos are supposed to have bugger all lag compared to the 2530's, good luck.

Hey Jack... either way you gotta be happy :rofl:. The boys were always pretty confident about your car making the power..no probs. I think it was only a concern about lag?? But by what you say @4800~rpm, that sounds about the same as mine. I tried to do an overlay of your dyno that you emailed me against mine, but the Kmh per hours are set differently, and I think you'll find that yours is not that laggy after all, in comparison my 2530's set up.

Hopefully my friggin clutch arrives next week. :rofl: once it does, we'll organise a day with the boys on the dyno.

Tribex.. I think Jack does have cam gear?? he can confirm, also jack did you end up putting some lightened pulleys? If so do you notice any difference?

Well done.

I'm curious, what did you make at 1 bar? what are these turbos equivilant too? are you running stock internals?

for cost of the PFC and Nismo AFM's I mite recommend the Wolf3d V4 which will also give you boost control and allow you to run a MAP table. Overall a very nice result can you do a run in shootout mode so I can compare my figures to yours?

my chart can be found here http://summoner.perthstreetcars.net/Cefiro...o/mark_dyno.JPG and this was done in shootout at 1 bar.

tribex- yes your right, they are meant to be less laggier than 2530s, but in the 8cm2 version, mine are the 10cm2 version so maybe that's why they are laggier?? Dunno...

Yes I have Trust cam gears....

Doughboy- standard cams, standard headgasket...

meshmesh- yeah full boost is around 5000rpm, getting used to the lag now!!!! As far as the Trust pulley kit, not sure if it made a difference....

rev210- yeah saw that thread, these turbos are apparently capable of 2 bar, don't know about reliability.... my car gets driven on weekends only, so doesn't clock up the k's....

summoner- I'm not sure what the car makes at 1bar, pretty useless running at 1 bar might aswell stay with stock turbos...

These turbos are equivalent to HKS 2530s rated at 600hp for both of them...

Yes running stock internals....

Didn't want to use anything but Power FC, personal preference....

Will do a readout in shootout mode in a couple of weeks when we do the comparison between my car and Simon's (meshmesh)... STAY TUNED!!!! By the way what turbos you running???

Don't think itas tailing off that much, feels very strong.... will have to check it out next time...

Summoner - you should know the rules by now! It's not permitted to use Wolf on GTRs in the Eastern States! :jk:

hope you got $'s for a spare engine then cause you'll need it.

We limited mine to 1bar boost and its running stupidly rich(fouls up plugs) so going to have to drop it down to maybe 12psi and cleantune up. Over 450rwhp and imho you are risking the engine.

My turbo's are equivilant to around hi flo 2540's... Efficiency is the key

I may not know the intricacies of tuning, but wtf has boost got to do with running rich/lean? Sounds more like your tuner hasn't got his fuel mapping correct than whether you're running too much boost...

I'm running 2530s at 19psi and my AFR is sitting dead on 12.0, I don't know why you'd want to run these turbos at a lower boost pressure than that.

Great figures without cams - I did a fair bit of reading on these Trust turbos and found alot of overseas people (UK) had major problems with longevity.

Trust may well have fixed this problem but if they havent I understand the following is the go:

1. upgraded thrust bearing

2. Oil cooler to reduce temps as they are oil cooled

3. hope for the best

Not wanting to appear pessemistic just what I have herd.

summoner & jezzzr, that's the first time I've heard such claims about the trust kits. At the same time, I'm taking it with a grain of salt, mainly because one of AU's most respected gtr builders Ben from racepace recommended these and infact built Ph1's GTR also with the Trust turbo's. Ph1 is pushing around 350rwk with these turbo's, and I am yet to hear he has any problems, perhaps he can confirm. Finally, don't get me wrong, but the pommies aren't exactly as upto date with GTR as AU are they??, and their not the most talented when it comes to engineering, tuning either...

I hope I am wrong (or rather what I read was wrong) because I will be getting a pair of these turbos if they are as durable as HKS/Garett etc, they clearly make great power. The thread that put me off is:

Its worth a read - UK may be behind us but theyve been using these trust turbos for a while.

Congrats on the results!! sounds like a very nice package :(

As for the turbo's longevity, i've never heard of anyone out here having trouble with them at all. Pete at advan backs them to the hilt, reckons they're the best bolt on low mounts along with 2530's.

It's funny there not having that problem in japan. Maybe they don't like english weather haha :headspin:

      Help Understand GTT Boost Setup

      By DraftySquash · Posted

      It was roughly 3.5 hours.    car went in around 11:00 and I was done around 2:30 He did the initial runs, install the BC and then Nistune install and tune.  The best part was sitting in the lobby and hearing the skyline on full throttle at the dyno 😂😂

      Glad it all went smooth. How long did the tuning process take?

      Yeah that was kind of the same feedback my tuner gave me.  the boost tee is until I can sort out my plan for the electronic boost controller and what I’d get, where I’d mount the dash etc.  I’m happy with this until I can figure it out. Not a big fan of the A-pillar gauges. I’d like to get a clean install of the boost gauge - something digital like GFB.  Something like that might fit neatly where the ashtray is and look clean. I feel like replacing the OEM triple gauge is a bit extreme for a weekender like my skyline. And it’s not making crazy power to need all the additional sensors/gauges.

      I'm about to swap my box to Tremec T56 Magnum F & initially thinking of re-using my DCS twin plate (can get it re centred for the bigger spline) but it's been called out the box will be noisy (rattle) as the clutch is unsprung.  So I'm doing as much research as possible. I'm not so worried about holding the power as I'll go the track version which on paper will hold the maybe 1000hp I make. It's the longevity I worry about. DCS told me they don't use a sprung centre as it's just something that can break. The uni clutch has a very complicated sprung centre. Any one had or heard about any issues with it failing? Thanks in advance.

      Auto is at least 10% (from my real, actual experience with different torque converters and manual on the same setup) ~185rwkw at 11.6psi (peak!) is entirely what one would expect without a FMIC or anything else on the intake, it does bleed off towards the higher RPM so it's what, 9psi there? Note: There is nothing that can be done about this with a manual boost tee. If you want to hold it steady and gain more top end, well - You will need electronic boost control.....
