Looking at doing some sort of heat shielding for my 2 pods that are just sitting there sucking hot air at the moment but wondering what to do about getting some cold air into them afterwards.

My gtst was easy as it already had a nice 3" hole from factory right where I wanted it.

My question is it safe to cut a 3" or so hole right below were the pods are then I could do the induction easily, just ive heard something about how it makes all the support weaker on that side etc etc. It probably wont be so obvious just looking at it from the engine bay.

Only other option I can think of is the headlight replacement but I want it for street use so that would be no good.

It has the stock airbox, but who knows what in it or if the box is modified?

LW.

OK I'll go another route.

Stock air box, Piper cross panel filter, custom stainless pipe to replace stock rubber one between turbo/s and AFM.

maybe ask Sydney Kid the max power he has seen from that set up on a GTR.

Honestly, when I had my GTST (R32) and had a pod filter, the thing was only producing like 155rwkw and the engine bay was so hot, the intake temps were like in the 60's during sydney traffic.

so imagine the engine bay of a gtr with 2 turbo's producing obviously more power.

and 2 pods taking up the same room.

even hotter air there for sure.

the stock air box is good.

GTST: I am aware of Gary's view on Pipercross filters: in fact I will be putting one in the (stock) airbox of my R32 GT-R very shortly.

My point was more that although the Mines R34 may have the "stock airbox", for all we know its been completely changed on the inside. I'm not sure it makes a particularly good point of comparison given all the unknowns surrounding the car.

LW - I was just trying to make the point of the stock GTR air box with a panel filter is going to be a better option that PODS in the engine bay.

AND it is cheaper to buy a stock air box and new panel filter, than it is to buy an aftermarket heat shield/air box which probably still uses tha factory snorkel.. to shield off the dirty used pods that would have come with the car from japan.

you will be able to produce the same power (possibly more) if using stock turbo's and maybe even with after market turbo's..

the cost of buying a stock airbox and panel filter is going to be cheaper than buying a heat shield for sure. and give a better result.

To answer your original question I drilled a 3" hole below my rear pod. I don't see how it has any effect on the structural integrity on that side. I have two 3" flexible hoses in the front bar. One running through the hole to my rear pod, the other through a factory whole under the headlight to my front pod.

Hope that helps.

Gary.

theres a factory 3" hole under your front pod? ah thats right yours is 32 so probably different.

You reckon 1 3" hole would be enough for the 2 pods? dont really want to cut 2 holes. Might cut 1 hole and put a scoop intake on also (hope it doesnt look ricey :Oops: )

The factory hole is under my headlight and was used for part of the air box setup that went to a resonator box. I thought the 33's would have had it too but I could be wrong. It is more like a rectangle hole next to the carbon canister. One big hole is probably enough though.

something like:

but for 2 pods :D

feed from top and make extra feed from bottom - would be fairly easy :(

      RB25DE NEO with Haltech ECU

      By Murray_Calavera · Posted

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.

      Could be correct. Meter might be that far out. Compare against a known 5 ohm 1% resistor.

      @Murray_Calavera  If I were an expert I wouldn't be in here looking for assistance.  I am extremely computer literate, have above average understanding on how things should be working and how they should tie together.  If I need to go to a professional tuner so be it, but I'd much rather learn and do things myself even if it means looking for some guidance along the way and blowing up a few engines. @GTSBoy  I was hoping it would be as simple as a large vacuum leak somewhere but I'm unable to find anything, all lines seem to be well capped or going where they need to be, and when removed there is vacuum felt on the tube.  It would be odd for the Haltech built in MAP to be faulty, the GTT tune I imported had it enabled from the start, I incorrectly assumed it was reading a signal from the stock MAP, but that doesn't exist.  After running a vacuum hose to the ECU the signal doesn't change more than 0.2 in either direction.   I'll probably upload a video of my settings tomorrow, as it stands I'm able to daily drive, but getting stuttering when giving it gas from idle, so pulling away from lights is a slow process of revving it up and feathering the clutch until its moving, then it will accelerate fine.  It sounds like I need to get to the bottom of the manifold pressure issue, but the ignition timing section is most intimidating to me and will probably let a pro do that part.  Tomorrow I'll try a different vacuum line to T off of, with any luck I selected one that was already bypassed during the DBW swap.  (edit: I went out and did it right now, the line I had chosen did appear to have no vacuum on it, it used to go to the front of the intake, I've now completely blocked that one off at the bracket that holds several vacuum lines by the firewall.  I T'd into the vacuum line that goes from that bracket to the vacuum pump at the front of the car, but no change in the MAP readings).  Using the new vacuum line that has obvious vacuum on the hose, im still only getting readings between -6.0 and -5.2.  I'm wondering why the ECU was detecting -5.3 when nothing was connected to the MAP nipple and ECU MAP selected as the source. @feartherb26  I do have +T in the works but wanted to wait until Spring to start with that swap since this is my good winter AWD vehicle.  When removing the butterfly, did it leave a bunch of holes in the manifold that you needed to plug?  I thought about removing it but assumed it would be a mess.   I notice no difference when capping the vacuum line to it or letting it do its thing.  This whole thing has convinced me to just get a forward facing manifold when the time comes though.

      Update: tested my spark plugs that are supposed to be 5ohms with a 10% deviation and one gave me a 0 ohms reading and the rest were 3.9ohm<, so one bad and the others on their way out.
