Relatively simple question, to which I fear there is not simple answer.

Anyway I have an R32 GT-R. Usual bullshit mods including pod filters & an oil cooler. Anyway I want to get cold air to the filters & have pretty much run out of room. My questions are two fold.

1. Does the R33 CAI fit on the 32's?

2. Has anyone managed to fabricate themselves something workable without hacking holes in the bumper etc.

Maybe u will have to bite the bullet and cut a hole or two under the air filters, and feed air up from the passenger side of the bumper.

This works pretty good on gtst's because there is room when u fit a front mount to run a pipe of some sort up to the pod.

It probably wont help you but i think the gtst standard air box gets its "cold" air from a spot that will actually be cold. Failing that ill probably cut a hole and mod the bottom of the airbox so it can feed directly to the bottom of the panel, and not so much tru the snorkel thing.

I can't use the area under the filters because the oil cooler is in there. It dumps plenty of heat. The most of the other areas in the front of the car are plugged full of intercooler, oil cooler, air conditioner heat exchanger, radiator, power steering radiator....

yeah I have the same problem and no easy answer. about the only one I can think of is remove headlight and have headlight duct. I have the same problem. big oil cooler in passenger side duct means no chance of getting air from there.

Baron, if I asked nicely could you see if your 33 CAI fits onto the top of the radiator in the 32?

I still use the airbox, I was going to cut a hole through bottom, and get some flexy pipe shit, and put 1 end into the airbox, and the other near the big hole in the front bar (to get away from the oil cooler)

I can't use the standard airbox - the AFM's won't fit.

Even then I can't see a spot for any flex piping as there aren't any spots left other than over the top of the bumper. I really don't want to hack holes in the thing.

perhaps move the bovs, from the drivers side and put the oil cooler there. bovs could find a new home in the engine bay perhaps.

or remove the ac(but keep the heater) and u might be able to get away with the oil cooler between the radiator and intercooler.

ac is overrated ;)

what oil cooler do you have? I have the trust one, and it sits a fair way back. I havn't measured for piping yet, but from a glance it looked like it would fit. but if you could fit a pipe through, i'd imagine that it would make a diference to your air temps even with pods.

HKS.

There may be some room to the centre of the blanking plate.

yeah no worries. actually I need to update my profile sort of. my silver 33 GTR was stolen, but I have another one which was just loaded onto a ship today. will be here in 2 weeks. I'll check then.

I got a hold of a stock airbox for mine to get rid of the pods. I'm switching to an apexi pfc with Z32 AFM's. Bolt holes are different but all I did was mark out new bolt holes, drilled em out and fitted longer bolts with locknuts on the back.

Just have to cut new intake pipes to turbos now when I get back.

Well that is great, but how do you get cold air to the airbox?

.............I'll get back to you on that one!!!

Seriously, my oil cooler is on lhs now, I used to have a smaller one on the rhs, in front of recirc valves(pipes removed). So I was going to open up the front of the box, duct in from below headlight, and divert some of the intake air from the lh lower intake(split it from oil cooler).

Have I lost anyone???

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
