[Mobies]

this write up is awesome ..! just one thing is i dont remember pulling anything off this metal hose been told its a over flow for the gearbox hmmm i dont think thats right since it travels up to the plenum area .......help would be great..!

[Koshi]

What size/thread pitch are those brass nipples?

[jUsT-dRiFt-iT]

Mobies yes it is an overflow/breather for the gearbox

Also did anybody have any trouble with their plenum hitting on the oil dipstick?

so i guess the stock throttle body can fit in these copies as long as i can find adaptor plate

i havent installed my greddy copy yet. how will i know or test if coolant would leak. any fix on this?

[blaikier33]

great post

but i would not recomend using ebay manifold i got one and when i had everything done i went to put water in and filled no two pot up with water. i relised this by water coming out of my throtle body before i started the car. pulled it of and it was leaking from water gallery to runner. porous cast aluminium. if u are going to do it i would highly recomend pressure testing.

sent it back and they sent me another one LOST POWER and the fuel rail didnt line up....

sanded and polished oem and refitted never happyer

and if you ar going to do this, mount the throtle cable Bracket better than in the picks, or your throttle body will stick open..

can make your own plate,its not too hard really,

'' mines all sealed up no leeks anywhere, but im haveing high idle problems now, even with brown plug off offaac valve,when that is attached it revs even higher. and idle screws one on air control i put right in helps abit. and little one on throtle is screwed outhelps a bit,but still somthing isnt right . with everythng set where it should be it revs at around 1500-2000 can anyone help? cheers.

[cuztomr33]

never mind,mucked round with it for a while,seemed to have come good now??

[SECURITY]

before fitting one of these you need to make sure everything lines up. i had to chop out a bit of where the AAC valve sits as when i lined it up i found it only had an opening of 1mm, i had to grind it out so it all sat properly - it would have definitely caused an idle problem.

[cuztomr33]

yes deffently,worth checking everythng, b4 putting on..pressure test a must.

[hopeless33]

[SimonR32]

Anyone know if you use a R33 Gts-t or R32 GTR top rad hose?

From the look of it GTR looks like it will fit better?!?

[Dale FZ1]

Stock RB25 top hose fits fine.

[SimonR32]

I don't have a stock 33 one

GTR looks like it will fit much better so I ordered one already!

Fingers crossed

Just FYI, don't get a GTR one it's a tad too short

Use R33 RB25DET one and cut about 3/4 of a inch off the end!
