After thinking about moding my Plenum to the end of the plenum, i found out it was abit hard to do on a r32/RB20DET plenum as the ends/diameter to make a hole to fit the throttle body aint that big compaired to a rb25det one which can & has been done.

You want the WHOLE piping in silicon? or just joints?

why not just do it in alloy or something?

It is not very hard to relocate the throttle body on the 32's, i was going to do it on mine and got a second plenum which i cut up and was going to weld the pipe to but i decided against it. The air has to enter and turn hard left to reach the first cylinder, this means there will be big differnces in the air recieved at each runner. You realy need to make a complete new plenum if you want short pipes and i was going to do this but it got all to hard.

However if you want a 32 plenum with the throttle body moved i will sell you the one i modifies for a good price.

hey i was wondering...how much are the plenums that go straight to the front of the engine instead of going across the top?

how much, where from, and is it worth it? im wanting a cooler soon, so i was thinking of changing the plenum first...if it was worth the trouble?

do people sell them second hand, if so, how much and again, where from...here?

      You’ll want to have the block drilled and tapped to suit 1/2in head studs and the head for the same. How much power do you intend to make?

      Sorry for resurrecting an oldish thread Not much has happened in the past year since the last update. The car did another 1000 miles or so and failed the MOT for the first time in October (failed on tyres which had been advised for a couple of years) In October the car got put up for sale and was removed in November due to no interest, being so close to christmas it was to be expected. The roads were dry in February so I decided to tax it early and get the new tyres fitted.   Fast forward to April, I got someone in to give the car a good clean after sitting for the winter.                                 The car got re-advertised and today (Saturday 3rd May) the car sold. The new owner is planning a GTR conversion at some point and a respray in the same pearl white. It's bitter sweet, it's a shame to have the car sit there for half the year and then only do 1000 miles. The kids are growing too quick and space in the back is getting limited. It's been a great 6.5 years of ownership

      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.
