I'd probably weld it too if it can be done successfully....forking out $1500 or more for an aftermarket job just to gain approx 5rwkw aint worth it IMHO

only 5rwkw? i know cubes says its one of the most important upgrades for the hybrid RB30 engines

im not saying luke should do it for the 26 and if he hasent go the money for it now, of corse try welding it up... but it should be something on his list of things to do for the 30!

The difference is going from the standard RB20/25 over the top intake manifold to a front facing manifold then there would be gains to be had, but Luke's manifold is a GTR manifold and there are plenty for GTR's making up to insane amounts of power still using the factory GTR manifold.

The Greddy and hypertune manifolds will give you slight increases in the top end when you are making massive amounts of power but you will be getting this gain at the cost of low down and midrange power, and like SLED said your only talking 20-30HP gains on a 700HP engine but your are losing like 80HP below 5000rpm

Well my Maxima plans may have changed

Me likey veeeerrrrryyyy much :thumbsup:

that is nice James, definitely check it out! a lot of goodies listed too

seriously couldn't picture you in a maxima mate... haha

just bought one of the turbosmart boost tees :thumbsup:

and on another good note, the 31 goes to its new home today!

Kocking off work at 1, rush home to wash/detail my cop of a car then race down to the showgrounds and setup the SAUSA display! what an arvo.

Haha yeah think im missing the 33 like you missed yours. Got a few guys to talk to about it to get a bit more history on it, but the guy that owns it use to work at Autobarn.

I may even be taking it out of context, it was a while ago i read it and perhaps it was just about 20/25's and i read 26's into it, but without actually finding the post im pritty sure it was also including (if not specifically about) 26's and it was sugesting a particular brand and not greddy/hypertune... and coming from an rb30 guy that knows his stuff so i'd take his advice, or at least strongly consider it, if i was doing any kind of 30.

in the end, its lukes car, lukes money and lukes goals so he can do anything he likes. i was just reminding him what cubes had said

absolutely!

and hey, did i read correctly last night on FB - the little yellow weapon is finished!!!!???

just bought one of the turbosmart boost tees :)

do you mean the turbo-tech ones Damo? thought you were having issue with the t-smart one

i second the turbo-tech tees like the others here, had one on my white 33 - held 11-almost 12psi up to very high revs. The Mines ECU had set the limiter @ just over 8000rpm too :thumbsup:

yeah i mean Turbotech :thumbsup:

my current boost curve drops off a fair bit, from 10psi down to around 7 by redline. holding the boost higher through the revs with the new boost tee will obviously affect my tune wont it?

yeah i mean Turbotech :/

Just got my siemens-deka 575cc injectors from the US for my GTR.... total cost? $360 for 6... cant wait to get em fitted... cheapest injector upgrade ever

-D

I wore boardshorts to the office today.

Fingers crossed I get sent down to parliment today to fix some sort of computer issue.

The ministers will love me.

put some sick german porn on koutsantonis computer and call today tonite

'omg laik wot a sicko is this guy'

-D

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer 
    • Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
