Hello, I'm a new member and would like to ask, I have recently purchased a 2003 Stagea VQ25DD, and am wondering whether to install a 5/16 Plenum Spacer, My questions, will this help lack of low down torque and as there doesn't seem to be any listed for VQ25 will the G35 one fit, it appears in the photo's to look the same. My problem is I am happy with the car as I couldn't get a 3ltr one when looking, I just find they don't seem to have much umphhh when pulling up a steep driveway?? Hopefully this makes sense, my wife likes the car, I just want it to be a little more exciting, but for the least amount of bucks. Cheers.

if our one fits your engine, i have one for sale, brand new with a gasket too!

Hello, thanks for replying, could you tell me which kit you have and how much please, what size motor where you going to put it on, and if I can ask, why are you not using it??

Ok, I think people are confusing two different types of spacer.

The one Iain has, goes beneath the inlet manifold and has a row of 6 holes, right?

And the OP is looking for a 5/16ths spacer, which generally looks like this- correct?

Truth is, I don't know anyone with a VQ25DD with a manifold spacer, and don't know if they are the same plenum. Good luck OP.

Heres one for sale: linky

Agreed Scotty, but I don't see anyone making those spacers for vq35's.

The Idea of the plenum spacer (in the pic above) is that cyl 1 and 2 are starved of air in the stock position.They are pinched into the front. By raising the Plenum, it allows better breathing for the front cylinders. Thats the idea anyway. After saying all that, I don't have one, nor will I bother rolleyes.gif

LOL... Got one sitting around somewhere... and on an HKS powered V35.

    • I hope it's actually possible. This is a write off in insurance world.
    • Yup. 2-way with shallow ramp angles. Still works.
    • That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together
    • I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain. 
    • OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
