Hey guys

About to purchase a motor and turbo setup.

Currently own a RB28 with almost unknown parts

Made 458kw on 22psi with a T04R.

Now was wanting to build a rb26/30 with a big turbo for street and to make big power.

I have found a motor and setup already built and was wondering other peoples opinions.

Its not cheap either but already done and built by a reputible shop that specialises in RB30 and RB in general.

I was unsure of the compression as its been left high on purpose

8:8:1 and it made 450rwkw on only 18psi with an auto behind it on pump fuel.

I am planning to run E85 anyway but can always change to thicker headgasket for less comp and more boost.

Apprently the head and plenum and exhuast side and turbo have all been matched to flow together.

Specs are as follows

Turbo:

Mr Turbo S72 GTS

800-1000hp rated

http://www.billetturbochargers.com/Billet_S72-GTS.ews

HEAD (supplied by 6boost)

- extensively ported

- 1mm oversized ferrea valves

- performance valve springs

- Tighe cams (274 intake, 278 exhaust, 11mm lift)

- Adjustable cam gears

- cometic head gasket

- rear oil drain in back of head returning to sump

BOTTOM END

- All the usual machining associated with a bottom end like this

- Argo rods and CP pistons

- 8.8:1 compression

- Ross harmonic balancer

- Jun oil pump

- oil restictors in block

- JPC sump

- half inch head and main studs

Im looking to make 500kw+ will the setup be right?

any help would be greatly apprecited

I would put it past it.was built by the business that builds all engines for "JPC" reputable Rb tuners and so on.

What do you's think about the turbo? I have no knowledge of these Apprently they spool quick for what they are due to billet compressor.

And any examples of that precision being used?

I'm interested in the s72 just want to here some feedback on it before I buy it.its with the motor and what he made the power with.4000rpm it reached 18psi with an auto

The thing is he ran a 10.0

Something felt wrong with it,

Was inspected at JPC and found the cooler pipe off the elbow of the turbo was coming off on boost,all of a sudden while it was on the dyno it started smoking and they found an injector failed and it melted a piston.

So it was pulled apart,inspected the bores and rebuilt the bottem end and it's still at the shop and he decided to sell it so basically I'll be buying a fresh engine.

Can't help with the billet turbo

Don't know anyone who uses one

Maybe give them a ring and ask about it,

My last dealings with them was good even though I didn't buy from them(I worked up the road from them upon a time)

They know their stuff and were happy to answer questions

    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
