what real gains are to be had removing the carbon canister anyway..1kw maybe

I also remember reading somewhere that in Japan race and drift cars are required to keep them, anyone know if this is correct. Cause those cars are mighty quick so it seems to me removing it is pointless and a waste of fuel..

How did you go removing the evaporator etc. under the dash? Or you not going that far.

I have removed the A/C from under my dash & its not hard...

Remove glove-box, from memory theres a plate behind there so remove that too. Then next to blower, directly under glovebox, is the A/C core in a plastic case, which is held in by a heap of bolts. Remove that then you can split it in half (held together by tabs) pull the core out, & refit the plastic case. This plastic case acts as part of the ducting for the heater & fan so if you use these, it needs to be refitted or replaced with something similar (have seen 4" domestic A/C tubing used) or you will have nothing.

Few things to note but...

The alloy A/C fittings that poke through your firewall are part of the core so if you remove it you will have two holes in your firewall.

Some grommets from Clark Rubber will fix that.

There will also be two holes in the plastic case where these same fittings poked through that. Once again, grommets or something similar will fix...

& lastly, I would suggest putting some flywire, etc between the two pieces of the plastic case when re-assembling it. Without this you will have a lot of leaves, etc come through the vents that the A/C core used to catch.

Fair bit (but not HEAPS) of crap caught in & around my core when I done this...

I think there would be no performance increase what so ever. I mainy removed it so I could mount a catch can in it's place and remove a bunch of vacuum lines.

I think most people would be removing them due to engine bay tidy up/making more room.

i hope you didnt just let the air con gas out.

R134a is Lethal to the atmosphere
R12 is also lethal yet no longer in modern cars and usually only seen older vehicles that are yet to be converted to r134a there would be a plate in teh engine bay stating which type fo gas you have. and if serviced by a air conditioning place and replaced with minus 30 thered also be a minus 30 service sticker in there properly. unless was done in a back yard job.
There is a cheaper gas going round which can be let out into the atmosphere though. known to most as (Minus 30)

Just for fi anyone views this thread for the same reasons please take your car to a registered Air conditioning place to get it properly removed.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P

      Help Understand GTT Boost Setup

      By joshuaho96 · Posted

      This would be a new pump with new gears. I'm just unclear on whether it's a good idea to run more oil pump flow if you don't actually need said flow. Oil level is set a minute or so after shutting off a warm engine so wouldn't the high RPM oil level in the sump end up lower all things equal? Plan is OEM clearances, main concern in my mind is whether the OEM pump can keep up with the flow requirements of any additional oil coolers.
