Or perhaps in that 700-800 hp range what would you leave stock and what would you upgrade using an rb26 head ??

Its very difficult to do a middle of the road bottom end really.

When I started doing the forged RB30's we had only ever planned for them to be 700-800hp/8000rpm capable and originally sold them as that (nzd10450 for short block) but then once we started winding them up ourselves and finding complete reliability at 1000hp/8500-9000rpm we have "re-named" as such although the basic design is very similar and the shortblock price is still the same, we then add a big custom sump, big oil pump and drive, 1500hp front damper, water pump, cam belt, idler, tensioner, extreemly accurate balancing, blueprinting and assembly and it becomes a complete bottom end for just nzd16900.

We have found, once you start adding forged pistons and good rods to a stock internal motor other "should do's" comes along with it and before you know it you have one of our normal 1000hp forged bottom ends anyway so its not easy to do one in the middle as such.

We have run a stock internal RB30 with some work to the stock rods to 8000rpm and over 800bhp in a track car and its been very reliable but most customers don't feel comfortable (and sometimes the tuner they use doesn't either) with such a basic combination and for piece of mind they just go with the forged.

If you specificly wanted to save a couple of grand on the bottom end I could come up with something for you though,

F*ck knows what power that motor would make with everything wound up to the max, and how scary it would be to drive the thing. Good luck Rob, and don't forget the videos.

I only have 6 x 1000cc injectors in there, we have increased base pressure but the new setup makes more power at lower boost so by 1.85 bar we have run out of injector where as before we got to 2 bar with lower base pressure with the same AFR's and inj duty cycle so its a good sign things are working much better.

When I can thrash the power the motor makes now I'll put some 1600cc injectors in there and wind her up some more and see how it goes, its got to pop sooner or later but at this stage its putting out good numbers and loving it.

We don't want it to go pop Well I know some probably do, to prove themselves right about over-priced OS Giken RB30's vs RIPS RB30's, and to show that you are talking rubbish about standard cranks being good enough for the job.

So far, that's exactly what has been proved, the standard crank is able to run at the same level that the OS Giken runs at. OS Giken reckon they are strong enough for 1400bhp or 1500bhp, I forget which, but nobody here running one has 1400bhp or 1500bhp anyway.

So your standard crank seems to be able to handle the power that you have no problem at all, and I'm guessing the OS Giken boys here are running at the same level of power, their wallets will be considerably lighter of course. I don't see how paying a hell of a lot more cash for an OS Giken is really worthwhile, at the levels they are being run at. The RIPS RB30 seems to match it no problem at all, and that's without a fancy crank.

So why bother?

I'd take a RIPS motor anyday, the cash saved could be spent on big brakes and decent suspension, and other handling improvements.


ps: I suppose when it does go bang, you'll have a nice reference point of where to stop trying to increase the power. I still think it's a shame to kill that motor though, it has served you well.

Shame you on the other side of the world, as I have a set of brand new 1600cc injectors here that would love a home like the Z!

Jesus man, take it easy!!! lol I don't like commenting either way on other peoples motors or what they chose to do and with what parts anymore, what you say may be true but it'll only upset people.

OSG's are good quality and stronger than the Nissan RB30 as far as I can see, needed for most people? thats just a matter of opinion/choice/budget.

We have very good power for the boost we are running and the motor is fine at this stage, if we get under 8.5 and we blow it to bits it trying to get a 7, I don't think anyone could really knock it too much seeing as it is a very basic stock block/bottom end with good pistons and rods with a conventional style wet sump etc.

It still has its very first set of spark plugs in it and its had 1 oil change when we checked the bearings at the end of the last season so I'm just as amazed as some other people might be, I really didn't think it'd take the high rpm and abuse I have lovingly dished out to it time after time.

Having said that, we spend ALOT of time being extreemly fussy and possibly quite anal about setup, mapping and preperation to give the old girl its best chance of holding together.

The race weight of the car is 1277.5kg (way over minimum weight for my class) and quite possibly only the times and mph we magage will confirm the power once and for all for others.

That's exactly what I mean. The OS Giken might be stronger, but at the levels they are being run at here, it's a total waste of money IMHO. If they were running anywhere near the limits of the OS Giken bottom end, then the times and speeds would reflect that, but that isn't the case.


As for upsetting people, I'm way past caring about their feelings, Rob. It's only the people who say you're talking rubbish anyway, and a certain tuner from up north's fanboys. Well, what a coincedence, it's the same people.

with your 1/4 mile calculator, what times would a lightweight pro-car with 1400bhp, and 1500bhp run?

I just want to get a rough idea of what an OS Giken equipped car would be capable of, if it was built up to the spec limit of the bottom end, I mean. I ask for 1400 and 1500 because I don't know exactly what the limit is on an OS Giken, but I'm pretty sure it's one of those two figures.

I'm not sure what the minimum weight for you guys is but here its 1060kg for 2wd or 4wd Pro Import (GTRs, jap tube cars etc) and some of the cars I race are right on that minimum.

Using the same formular we always use and lets say 1500bhp gives 1300whp with a good transmission etc, in 1060kg its a 7.15 @ 194mph

If we go with a more common weight for a pro GTR of say 1250kg (about the same as the 240z) and 1300whp its 7.5 @ 184mph

So HT running 190mph+ at probably around 1200kg just shows they are making MASSIVE power and guys that hit around 165mph are in the 900-950whp range usually.

Thanks Rob, that's exactly what I was after.


I wonder what the Heat Treatments car would run if it was tubbed, and running on a nice big pair of slicks?


Sorry, I just had to include this pic

[trackday addict]

Pro Class weight limit has been lowered again for next year Rob & from memory is approx 1090 kgs (inc driver)

Mine with me in was 1190kgs so we could loose more but being honest it's not worth the cost to be honest, approx £6500 for a complete 1 piece carbon front end to be made & ok by shedding 100kgs we could probably save another 1/10th & a bit but money better spent eleswhere & that time will come out by more boost & finally turning the gas on hopefully.

HTL i'd stab a guess are running around 1800 - 1850 bhp, methanol obviously helps to some degree but fantastic engineering from them - they have done an amazing job with keeping the head on etc as they have got quicker

On the 20/11/08, Heat Treatments had their GTR on the dyno. Kevin Macgregor said, "We ran the skyline on the dyno wed afternoon and things went great... Nice stable power and the pressure gauge on the radiator to help us spot any head gasket problems didnt move off "0" for the whole afternoon, even at full power. The head and block design we have come up with has worked. Next up is some track time on the 6th-7th dec".

I assume they're taking it to Meremere, which is where they have a pit permanently based I think. We'll have to get Rob @ RIPS to keep us informed of the days events, I shouldn't imagine him missing that weekend for one moment

[trackday addict]

Fantastic team & they will move that car forward again without a doubt
He's a brave & talented fella Reece when you watch the vids - incredible torque steer throughout the run but he keeps it planted

[Boosted]

Yeah I know, the car snakes its way down the track and just keeps getting faster. I definately think they are going to beat their record, it sounds as if the car is faster than ever, and they seem pleased with their results.

So, low 7's maybe, or high 6's?

I wouldn't like to put my money on it, but I'm sure one set of those times will be matched by the Heat Treatments GTR.


Low 7's I reckon

I'll be there with bells on and I'll actually be racing in the same class as Reece I believe so with any luck I'll line him up at some stage, I'll get my ass handed to me on a plate but I won't care one little bit cause I'll be able to say "I raced the HT GTR in a proper Pro Import race and have the vid to prove it"

Judging by the way that car uses all of his lane its probably better that he will be WAY out ahead of me, lol.

Can't wait.

We need lots of video Rob, lots of different views, send everybody you know that owns a video camera to that meet
