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

      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.
