Intake Plenum Question

Hi Everyone,

Does anyone have any info/suggestions with regards to the standard intake plenum I have on my R33 GTS-T with the piping running over the motor to the throttle body.

Which of the following options would be best?

1) Aftermarket plenum (e.g. Greddy). I know that I can get one delivered for just over $1000

2) GTR plenum...is this possible? if so what other parts would need changing to make it fit? What would the cost be?

3) Have the throttle body location moved on the standard plenum? Is this possible? What would the cost be?

...or is the standard plenum fine as is running the piping over the engine from the front mount and spend the money on something else? I am looking at getting power up to 300rwkw, and thought that the heat caused by running the piping over the motor would not be as good as having the piping running straight up to the throttle body like the GTR.

Any info/help would be greatly appreciated. Thanks

Did you try searching the forum?

I think sydneykid mentioned the stock plenum was good to a specific power figure but I can't recall the figure.

Ed, after a bit of searching with different search criteria, I came across the thread you were mentioning. Sydney kid mentions the standard plenum can cope with up to 450hp without restriction...not sure if this is crank or atw.

So I can definitely forget the aftermarket plenum and stick with standard. :D spend the money on other things for the car instead.

What about the piping? Will the piping to the standard throttle body position get in the way of a high mount GT35R?

The 180 degree bend at the throttle body style of pipework is the go.

I have a picture of a car fitted with the 180 degree pipework and a high mount, but this new forum is taking some time to get used to.

:D cheers :P

Hey SK, thanks for the pic...looks like it should shorten the pipe a fair bit and looks good to. Was that custom piping made by anyone in particular?

Thanks,

side note, you dont need a GT35 to make 300.. its overkill.  :)

I was also looking at a GT30R with a .82 A/R...may still go for this instead of the 35R. ;) cant wait to start working on it all but will have to wait another year. Then I will give it some attention. :)

Just letting you know thats a Hypertune/Performance manufacturing piping kit.

They have moved from inside the same building as where plazmaman is, but they are now down at Tarin Point.

They will also be doing a plenum for the RB25 very shortly wich replaces the inlet runners.

These are the guys that did all our piping on our GTR.

Give then a call

      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.

      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.

      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.
