How-to: Greddy-style Plenum Install

[GOLD_JET]

hey guys just wondering if anyone has done this conversion on a 34 neo engine. throttle body is alot different. so i bought an 80mm t/b but just wondering what i do with sensors etc. cheers

[SmashBoxx]

well done!

[NYTSKY]

Where do all the vacuum lines go off the plenum?

[GOLD_JET]

anyone lol? just need to no cause of sensors if its worth it? cheers

Just use the non neo throttle body, otherwise i dont think you will be able to fit the intercooler piping . Just means you will lose the Traction control.

[GOLD_JET]

yer i already have the 80 mm one and it fits ok. if its just traction control ill loose that will be ok lol

[GOLD_JET]

if i have an r34 instead of modifying a bracket to fit the iac would it be easier and work to just use a standard r33 iac? cheers

awesome write up!

one quick question, if anyone can confirm for me.

looking at these pics and description, you have used the existing hole below the washer bottle from ur previous fmic setup with the std plenum. (im asuming?) but you have not retained the std washer bottle. my questions are:

although u have used the existing hole, are u stil not able to retain the washer bottle? or do u have sum form of aftermarket washer? (i cant see anythng)

what i would like to do with my setup is use the exsiting hole from my greddy fmic setup (same location as pictured) and also retain my std washer bottle. is this possible?

Heres mine (genuine greddy, not the copy) should also answer SK's question regarding reusing the GTR/Hybrid intercooler style hole below the Washer Bottle. I re-used my RB25 injector rail also which I painted with oil/heat resistant wrinkle coat.

yes it is possible. but it is necessary to have some pretty hardcore sharp bends.

in the end me and my mechanic just used the washer bottle area. muuuuuuccchhhh easier.

and im sure u can buy a twin motor washer bottle somewhere else.

something small like a s13?

[mattysaidso]

hmmm, the bends on the above pictured setup dont look to sharp though?

I bought a generic washer bottle from Repco and fitted that to replace the stock one. I'll take some pics tonight and post them up

i have a couple of quetions about this install i really want to do this at home as a D.I.Y project, but without a welder am i in trouble, as i need to have nipple added for the boost controller set up on I/C piping, the ACC pipe of the i/c piping (as shown in the tutorial).

Where does the B.O.V vacume line connect to as well, as it did not mention it in the tutorial as i would also have my B.O.V relocated under the wheel arch.

Putting a nipple in shouldn't require any welding, you can tap into the piping. However the AAC piping will require some welding due to the size of the hose.

There are several vacuum line points on the side of the plenum, allowing you to use these for BOV, Fuel Reg, etc.

[H@ME]

thank u for that, but how exactly do you tap in a nipple to the alloy cooler piping??

[PSI Parts]

Basically drill a hole into the intercooler piping one size smaller than the nipple thread, then put the nipple in by twisting it. The thread should bite into the metal and keep it steady. Some thread tape will also help with the seal.

I did this DIY and went the el stingy option and managed to use the old pipe that went across the engine so i had the AAC valve hole and BoV mount already with all the vac lines if i had to double up i just threw a "T" piece in with some check valves

Sounds like an 'interesting' but smart way to go about it, i am still smoothing and working on mine till i think it is fit to go on the car. i'm sanding it back and polishing it up, i will have a pipe welded in for the ACC valve and the bov mounted under the wheel arch, then i will thread a nipple for the boost controller, unless i get a kkr480 which dosen't exactly need a boost controller. cheers, hame.

hey guys just finding it hard to figure out where the water solenoid plug goes i've got it (the blue one) just cant find out where it goes..

[H@ME]

Also just thought i'd add a pic of how mine is going.

another step that was forgotten from the tute was that the sensors for the water temp need to be put in just before where the top radiator hose gets plumed in..

can someone answer my post above!!
