Now, remember that bit of fuel line you cut off before, let's re-use it smile.gif Remove the bracket from it like below. Cut, cut cut! Strap it to some fuel line we bought earlier. You only need

i will be ordering a FF intake from Vulture Motorsport soon, takes standard TB (R33)and is available in Aus for a reasonable price, same intake gasket part number for R33/R34 so it SHOULD physically fit a NEO motor but may have other fitment issues on R34

Thought id post some pics of my plenum.

Used a genuine Greddy plenum and Q45 throttle body had zero problem fitting after looking through this thread. I didnt flip the injectors or fpr (i think it looks neater), also ran the coolent lines through the throttle body.

3rd pic shows where i mounted the stock bov and 4th shows how i plumbed it back

Performance wise bit of a drop in the mid range, but made an extra 4kw more :cheers:

Great job man very neat!

How did you go about changing both the cam cover breather barbs to the single outlet 90 degree ? do they just push out?

Ok so can anyone tell me what I should have plugged into the Vac nipples on the underside of the plenum?

Im thinking BOV, Rocker cover breather, FPR...... What am I missing?

Carbon Canister if you are still using it

And are you sure rocker cover breather was one of them?

Should be BOV, FPR, Carbon Canister, Boost gauge

EDIT: You must have been talking about the larger Nipple that goes to the PCV valve

I changed mine around so it looked a bit neater using the stock fittings and the stock position plumbed into the intake pipe. I pulled the T fitting that points straight up and out as well out and used a bench grinder to shave it down enough so that it would fit into the cam cover, neatened it up before I put it in but thats basically what I did

heres what it looks like:

so where exactly does that line that comes out the side of the rocker cover go? Also, when I got my rocker covers ceramic coated I think the guys took out the o-ring or whatever it was that was in there... is there anything else I can use to connect that line with the one way valve?

The line that comes out of the intake side of the rocker cover is the PCV (Positive Crankcase Ventilation) valve. If you just have an empty hole there, then they have removed the whole thing and you will need to find another one. They are pretty small and basic but the setup wont work unless you have a working PCV valve in there

It goes to one of the nipples on the intake manifold (i got a bigger nipple with mine which is the right size for the hose needed to go PCV -> Manifold

yeah well I have still got the hose with the one way valve attached, but I think there was an o-ring or something in the hole before that held it in there. Maybe it broke when we were removing it? Anyone know where I can buy a new one?

ATTENTION: DO NOT PM ME ABOUT "PICTURES NOT WORKING" OR asking me stupid fking questions (that are already answered in the thread) about this plenum install I did 5 years ago - using the words "lol cant werk out how to buy brass nipples dat fit aye" - If you can't read/comprehend - not my problem.

Yeah this is fair enough, the Guide (and the following pages) are more then enough to do the basic install. The rest of the stuff (like cooler piping, BOV location etc) need to be worked out on your own.

AFAIK Autobarn will sell you the fitting kit for these anyway, thats where mine is from and I got a bag full of bolts, nipples, joiners. Everything you need pretty much to put the plenum on

Hi there, I'm new to this forum..I have a few issues with the plenum/injector seals! I have a top feed setup with top feed Bosch injectors. The plenum came with 6 little bosses for top feed injectors. I have put the o rings on these and put the o rings on the injectors! The metal bosses are loose as buggers! I have been told to buy gtr seals and get the metal collar on each injector machined to allow the seals to go into the plenum with the injectors. This also means I will have to shorten the fuel rail spacers lowering the height of he rail..is there any other way of fitting top feed injectors creating a seal?

Thanks for any info

Stef

      I would absolutely be starting with this idea over all other possibilities. It sounds f**ked.

      I would be cautious with those 2000/2200 CNG injectors, swap them out for a set of 1550 aka 1650 Bosch stainless ones before you take out a motor.

      Problem with 5th after manual swap on R32 GTS4

      By TheOrangeSkittle · Posted

      I tested them all a couple times, haven't tested it warm or wet though. The only seemingly really weird thing was the cylinders plug closest to the dash was pitch black nearly.  Doesn't smoke out of the exhaust or anything.    Also sorry everyone for the very late response. Got busy with work and all and didn't get around to fooling with the car for awhile.  But an update! I figured out the cause of the lean condition, my intercooler had at some point exploded or something. It's clearly separated in a spot with black oily buildup around the leak, and multiple leaks in various vacuum lines. I've replaced it and the vacuum lines, and gotten new clamps and there are 0 leaks now after doing a couple smoke tests.   The car now runs significantly better and the exhaust doesn't overheat anymore. I still have the main problem though where the engine feels like I'm lugging it around sub 3500rpm in any gear besides 1st, 2nd It's less noticeable but 3rd anything under 3.5k and I need to downshift or the engine is clearly struggling when trying to accelerate at all, 4th is the exact same, sub 3.5k engine won't accelerate and its hard to bring it back up to speed, 5th gear doesn't feel like the car is going to straight up fall apart now but it still can't pull 5th. It slowly loses speed and rpm and ANY gas I give I can feel the shakes from the engine and it slowly dying. If I ever so lightly give it gas it will slowly and nicely decel till around 2k rpm instead of lugging. But it cannot accelerate at all or maintain speed.   If I go from first gear at 5 or 6krpm and then shift to second it also feels like it's struggling to make power till above 3krpm if trying to accelerate but I can cruise around parking lots at around 1-2krpm just fine in 2nd. It's just when accelerating hard it and changing gear you really notice it die down.  But even if you shift at way lower rpms it does the same thing till somewhere above 3k.  As far as I'm aware it's got r32 gtr transmission gear ratios with gts4 diffs. The tire size is 205/55r16 91h Above 3500rpm the car pulls and runs and drives quite normally and the power from engine sounds and feels very smooth.  It's perfectly driveable at above 3.5krpm but I drive on the highway alot for work and it gets really bad gas mileage in 4th at 4.4krpm. Not that I'm looking for great gas mileage with such a car, just I'm sure being at around 3krpm would be significantly better for it.    Have appreciated all your guys help. I do understand the engine may just be f**ked from running with a boost leak though.    One final thing I'd like to add is I'm only shifting so high in the rpm range is because if I don't I will feel the engine lugging bad with 0 power in lower rpms, pretty much anytime off boost trying to accelerate it feels really bad.  Also when I say 3500 rpm I don't mean exactly. Just around there.
