Rb26 Plenum Onto Rb25

[Sambo33]

Hi people!

has anyone heard about blitz making a billet adaptor plate to bolt a 26 plenum onto a 25 head?

just wondering what they are priced at?

and where can i get one?

cheers

Yes they do its around 1k as i looked into it a while ago,

i was told that it replaces the existing 26 butterfly set with a new to mate up to the

25head seamed a little $$$$ unless you already have a 26 plenum.

i think zac from slidwize can get them still, i did get my price thru autobarn

so it may be had fro around $700-$800.

not sure how you would go with the aac unit and a few other bits tho. in

terms of hooking it all up, greddy plenum seams to be about the easy way

to go or something or a similer design. but the sound really, of 6 throttle bodies does sound good tho

Good luck

dude i looked into this. with all the messing around you are better off going a greddy or similar style plenum

I thought someone dug up ages ago some sort of twin plate thing for grafting the whole RB26 inlet manifold system onto the RB25 head . Not sure which one ie R32 or 33 RB25 heads but I think it was some Japanese aftermarket item .

Can anyone explain why the 2JZGTE can make seemingly huge power from a single forward facing plenum style manifold yet no one can do as well on an RB25 ?

thanks for the info guys. i called autobarn and they said about $700. seems like a bit more messing around than im willing to take on right now, greddy type might be the go i think.

You can make adaptor plates yourself that`s not easy but not impossible. Or you can buy it from yahoo: http://page9.auctions.yahoo.co.jp/jp/auction/k37245638

as far as i know yahoo staff needs custom machining.

Hey,

The Blitz kit, isnt just the adaptor plate, it inc everything so its just a bolt-on mod, that is why the price is around the $700.

Also you will need an aftermarket ecu as you will need to run gtr injectors which are larger than the stock gts-t injectors, and if you can get the piping from the plenum side off a gtr that would also be helpful!

I've look into it and the results look good (increase the mid range responds of the car) in the end the cost will be about the same as a greddy kit

$700 for the blitz kit + $300 or so for the gtr plenum
