That turbo can support 72lbs/min, which could be as high as 850hp on an efficient engine. It's got a terrific compressor map, can support high boost levels as well. Nice turbo

Hey so, hypothetically, I could refer myself to you, pick up a spotters fee and get a bargain GT-R in the deal? Sweet!

Is the 2004 'blade out yet? Last time I checked they were still selling the '03 model.

Volk challenge? http://www.skylinesaustralia.com/forums/at...tachmentid=8986 There are a few more pics of them, just do a search.

Depends alot on what you want to use it for. If, like 90% of R1 owners, you want to do laps around shopping malls and McDonalds carparks then get the R1. People know it's the best. If you actually want to use the bike then you'll have to make the decision yourself. What are you planning to do? Commute? Track days?

Hey I'll hire a promo girl to deliver it to you for $7K. She love you long time!

Brand new T51R SPL B/B for sale. Turbo only, in original packaging with manual. Asking $5000 for it.

They are magnesium covers, there are a few sets around but they are going for $AU1500+.

92mm pistons? You sure you don't have a water-in-oil issue?

Cause you're a size 7? Prodobably because you're getting alot of blowby and don't have a catch can attached to the cam covers, or the cam cover vents are blocked?

Very questionable statement sirrah!

That turbo kit looks pretty familiar - who owns it now? What sort of flow figures did you get after the headwork?

SK, you still need an international licence for Indonesia. Found that out this weekend, that's the last time I take what you say as gospel! (Fined $US10!!)

All inline 6 cylinder engines are internally balanced, therefore the clutch and harmonic balancer do not have to "carry over" any external weighting and are neutrally balanced. Looking at an RB26 vs an RB30 balancer there is not much external difference, but given the fact that the RB26/25 are a later model motor I would assume that they are both a) made from better materials and processes and B) there is less chance of the rubber cushioning material to be damaged since it should be a lower mileage motor. It all comes down to the fact, how much horsepower can you afford to make? edit: all the RB series are interchangable, from harmonic balancers to flywheels/clutches.

All motors have inherant harmonic issues, so you can't single out the RB30. You'll notice that anyone building up a "decent" modified V8 has plenty of aftermarket harmonic balancers to choose from, and this part is generally always changed. Unfortunatley, the options from Japan for the RBxx series are the ATI/HKS fluid damper ($1200), the Greddy billet alluminium hub (no balancer, ~$600) or a Route 66 rubber damper ($1000). The ATI item is the best available, buying it through HKS also gives you the pulleys, if you go direct to ATI you can get it a hell of alot cheaper but no pulleys (go go Gadget fabrication) and there are 8 or to choose from with alloy or steel shells. Having said that, there are plenty of RBxx motors using a standard one without any dramas. However, at high RPMs I think that the harmonic balancer contributes to oil pump failure and also crank damage - I've seen a few RB26 cranks with the keyway split or the hub for the oilpump damaged. So I guess you can add this part for a no-holds-barred, no beg-your-pardon's type motor. But it's not a necessity.

I think the power difference comes from the level of restriction in the exhaust housing, the flow should be the same due to the compressor being used. Anyway, free bump..

Edited.

With the OS 3 liter block they reline the bores with bigger diameter + longer sleeves. As well as using a full stud kit. By using the machined sleeves you get around the weak casting issues, but can bring some of their own problems (like shifting bores). And for the budget conscience (like myself) there is concrete. And donuts.

I ate a really big donut one time and split my pants. Does that count as real life experience?

For once someone has seen the light and are dropping in a Kei motor! Do valve covers come with the head? Has there been any porting to it?

Ok I am confused about what compressor wheel is on this. The GT40 82mm wheel has a 50 trim compressor wheel, whereas the 68mm GT35R wheel is 56 trim. Also the rating on the GT40 is 650hp, and the GT35R is 600hp. These spec's pulled off the Garrett catalogue, I know Ray Hall has some other specs listed but he's also got the GT35/40 listed at 60lbs/min for the 56 trim wheel, which is pretty optimistic to get 700hp w/1.06 rear housing.

Flogged from Andrew's site:

The FJ24 motor is pretty rare, it was developed as a race special. I've seen a couple sell for ~$7000, and these were motors in pieces with no intake or exhaust.

Depends if you're working on a VVT head or not..
