After thinking about moding my Plenum to the end of the plenum, i found out it was abit hard to do on a r32/RB20DET plenum as the ends/diameter to make a hole to fit the throttle body aint that big compaired to a rb25det one which can & has been done.

You want the WHOLE piping in silicon? or just joints?

why not just do it in alloy or something?

It is not very hard to relocate the throttle body on the 32's, i was going to do it on mine and got a second plenum which i cut up and was going to weld the pipe to but i decided against it. The air has to enter and turn hard left to reach the first cylinder, this means there will be big differnces in the air recieved at each runner. You realy need to make a complete new plenum if you want short pipes and i was going to do this but it got all to hard.

However if you want a 32 plenum with the throttle body moved i will sell you the one i modifies for a good price.

hey i was wondering...how much are the plenums that go straight to the front of the engine instead of going across the top?

how much, where from, and is it worth it? im wanting a cooler soon, so i was thinking of changing the plenum first...if it was worth the trouble?

do people sell them second hand, if so, how much and again, where from...here?

      He's right ~ there is no 'magic' with stuff like this ... it is more likely that in the process of looking for the short, the loom/wire 'incidentally' got moved in the process, thus removing the short ~ now, that maybe a wire (in a loom) rubbing against the edge of some grounded metal, that's worn through the insulation, causing the (now intermittent) short to ground. If one wire in a loom has been damaged in this fashion, it's reasonable to presume that other wires beside it may have also be damaged, and now exposed...you can bet the green crusty copper corrosion will start... ...that'd be a pisser, Murphy's Law steps right in as GTS observes...but worse, something like that is easier to find when shorted...ie; unplug bulb and fuse, and put multimeter in continuity mode so you get constant beep, and carefully poke about hoping to find if some movemet of the harness stop the beeping.... ...it's still all a bit Arnie tho' ..It'll be back... 😃

      Yeah, but knowledge of one wire's insulation worn through to short on earth implies the possibility of other wires doing the same. I had my power steering die, because the wire that runs to the solenoid valve on the rack runs in the same loom as the power wire for the O2 sensor. And when the O2 sensor/wire did something stupid and burnt part of that loom to death, the only indication was the shit(ter) fuel economy and the heavy steering. It took deep excavation of the looms in the bay to find the problem. Not wear through in that case, but similar shit.

      Ah, I thought he'd wired it to one of the spare ECU inputs! Too long ago since I read that post, ha ha. I've been arguing with radiators, harmonic balancers, alternators and rust since reading it.
