we overlayed our circuit cars dyno chart with both power and torque against the GT-RS's on the drag car and you would swear it was the same car.

The low mounts at 22psi and the T04Z at 24psi...same power but the low-mounts power was made a little earlier and held on for longer...same with the torque...both are HKS powered cars but the circuit car was on Sunoco and the drag car was on BP98.

Wow interesting! What comparative engine spec? I'm not a fan of the T04Z and I am a fan of GT-RSs so I guess in my head its two better matched turbos against a dinosaur with a nice core. Any chance of sharing the overlay? It would help a LOT of people considering the options.

I wish there were more GT40-based setups on RBs to compare with.

There is more to this story though....the T04z was tuned to make every single KW...13.0:1 at 24deg GT-RS's were using a run in tune... 11.5:1 at 18deg.

Engines using STD cranks...87mm forged pistons...similar head porting and camshaft profiles (circuit 280deg drag 288deg)...both z32 power fc cars using blitz boost controllers.

Thats pretty interesting, with my main purpose using mine as a daily driver i want to be able to give mine a stab and not have to wait til the next set of lights before i hit boost....

thats why i'd be leaning towards 2.6 + GT3540 or RB30 + T04Z

i don't mind the -7's but they won't deliver the top end power that i know i will want in the future

i dont want to open up old wounds, legit question this.

the built bottom end from NZ costing was it $1200 cheaper then the one from Aus?

Anyway, question is, whats the shipping fees involved or do you have a warehouse over here?

Ive seen over seas shipping for software, it isnt cheap, i cant even imagine the price for a motor...

Also my other question is, if you guys can produce a turn key motor that runs 9s for 19k or whatever... how come it cost some guys 100k for their machines? i may be missing something here, but if someone could PM me the reasons or differences that would be appreciated.

Thanks,

100k - there is more to a "Machine" than the motor mate and some people also add how many times they have broken things / changed things to get there final $$$ figure

My motor was $450nzd shipping in a crate from RIPS in Rotorua - Melbourne Australia

cause i build my own and have my own machine shop...$19000 is just parts! But to be fair to Robbie...that was when $1 bought 100Yen. Same build would now be very expensive...if you care to look back a page or two i actually admitted i was wrong...which is a bit of a rarity on here for people to do even when they know they are wrong. When you look at it in today's money $19000NZD is about right.

Also it takes more than 1 build to develop a car to sub 10 times...im on my 3rd engine now to shoot for 8's, my 3rd turbo set-up, my 3rd different type of gearbox, my 4th type of clutch, my 2nd type of diff...shall i stop now?

You dont just tick all the boxes in the parts catalogue, bang it all together and go and run the numbers...it just doesn't happen that easy...i wish it did.

Not only did Mr Dirt admit he was wrong he also eluded the possibility of crossing to the darkside and playing with a dirty 30 :)

i said increased capacity...i dont see anywhere where i mentioned robbing the trusty forklift of its power.

im building a 30 though...its gonna be big...its going in a VT Commodore wagon.

That could be why his nut sac is hurtin. They're growin.

nice one silver fox...ill pay that for sure

honestly i don't really find it financially justifiable to only increase displacement by 1 or 200cc it may make a difference however i have come to the conclusion that if i do stroke my 26 it will get some form of a R I P S RB30

interesting. I did look through the pages, and that is what i thought, that it would take a few builds to get the car running 8,9,10s etc. Just wanted check.

clear my mind a little :sick:

Should also say, gratz with the power. are you after track and drag times or just dyno power?

Thanks,

RIPS current shipping by sea rate is nzd600 which is still pretty good I feel except that any engines ordered this month or next get free shipping so its even better :-)

There's alot in building a quick car and the motor is just a part of it, we do have some very well proven combinations now where 10s, 9s, or even 8s with a very streetable motor is actually quite possible where the other areas of the car has been done correctly.

:glare: Don't tease like that!

    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!  
    • While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.
    • Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
    • I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.
