300kw-320rwkw easy??? spent about 25k on performance parts an labour to get 300kw atw. Prob cheaper if u find a happy dyno or dont tie the car down real tight to allow it to ride up, from wot i've been told it can make the exact same dyno read about 50-80hp different, depending on how u strap it down. As for the longivity of an engine's life (built or unopened) people usually only seem to quote a certain amount of years/months which isnt really informative, amount of track time, km since rebuilt, %of time driving the car spirited (or over 5-6k rpm) would be more informaitive. as a car that only does 3000km a year an 1 track day, an gets babied, is a lot different to a car that does 20,000km a year a 4 or 5 trackdays a year an gets thrashed every time it gets drivin.

I'll point at Simon and leave it at that ;)

Give me 25k and ill build you a 500kw+ engine lol, also you'd be lucky to gain 15hp by letting it ride on the top of the rollers, easier to put the air temp sensor in hot water and gain 30kw =)

I'd say VQ35HR, then TT (with 2 x 2860).

It will take 50kg out of the front of the car, have more power and torque and last longer. But you'll have to build it first.

I don't see much between a Neo and a RB26 for power/longevity. I'd take a stock NEO for the money with GT30 (0.86) ~280rwkw easy. Once you get over 200rwkw/tonne you're getting into serious grip/chassis issues.

what chassis issues would be ran into? for example a gts4 with a rb26 making 350 atw

The fact that he can run a very reliable and safe 330rwkw+ all day every day with nothing but injectors, fuel pump, exhaust, computer and a set of turbos or a single on it where as the Neo would be a ticking time bomb at those power levels on an unopened motor..

so we're clear here , what do you think the big difference is between the two internally , apart from the piston itself? .

If i were going to build an engine from scratch , i would start with a 'rips' 3 litre bottom end , and put a 26 head on it .

But i have to ask, do you have a car to put it in? , if the answer is no , don't bother with anything engine wise until you have one, there's no point having 400rwk if the rest of the car is dead stock , there is no way you would be able to use the power anywhere . If you want to spend your money wisely , put it in the bank , leave it there until you can legally drive the car you want to . If you still want the same car then , there will always be a few for sale somewhere , you may be lucky and find one with all the hard work already done.

what about a 300zx motor forged with heavy porting and a couple of gt28's bolted on with 25psi with E85, big cams etc...

or an ls1 with twin turbo and supercharger :)

3 parts, multiple pages each.

This car has nothing to do with me. But there has been VQ put into r-chassis before. A friend is putting a VQ30DET into an S15 at the moment (the parts are pretty cheap for the HP).

      Rb26/30 build

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Rb26/30 build

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.

      2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.

      Rb26/30 build

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
