has anyone done a gredy plenum on to rb25det neo

can you give me idears of what parts required

ie do the metal water lines under the intake fit

aac valve issues

fuel rail and injector issues

thanks in advance

I suggest you save all the money from wanky plenums, ra ra and go with a pov spec frankenstein RB25/30. There are many guys in the dyno thread easily smashing down 300 kWs with stock plenums.

Being technically minded, you should be able to slap the motor together with ease. RB30 motor/block from wreckers shouldn't be more than $200 ~ $400 with no ancillaries.

post-16614-0-93957400-1292233854_thumb.jpgdo we realy need to have twin gates with twin scroll?

I wouldn't bother with a dual gate twin-scroll setup on a straight 6 as its not a true twin-scroll anyway . This is just my opinion, each to their own but i don't think its worth the cost of the second gate compared to a 4cyl setup where both paths are kept completely seperate.

LOL

Firing order is 1-5-3-6-2-4.....makes twin scroll easy on an RB

You asked for suggestions and the cost effective solution is an 82 rear for your current turbo - 44mm wastegate (run it off the turbo) modify exhaust to suit and retune.

If you really want a sixboost and greddy (copy) plenum don't ask if its a good idea (you'll be told they are not necessary) just go and do what you want to any way with your money. If you have to have a FF plenum its a simple matter to change your brake master cylinder for a shorter one ( a drop in the bucket cf what you want to spend).

Whaaat?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
