The R34 has panel type filters in the air conditioning duct, between the fan and the evaporator.

I do have it with detailed pictures in a word doc, but it is too big for an attachment on this forum. Text only to follow...............

R34 Air Conditioning Air Filters:

SAFETY>>>>>>>>>>>All yellow wiring is related to the AirBag System. If necessary, disconnect battery before starting work

The R34 model has 2 panel-type air filters, to ensure clean air is passed through the evaporator coils. (I haven’t seen this feature on any other car before.)

Like any other filter, they also need to be cleaned, so here is some info that might make it easier next time. (It’s like brain surgery………….., easy….. when you know how.)

1. Remove the passengers-side sill trim (lever up with screwdriver, attached in 4 places)

2. Remove passengers-side kick-panel (unscrew plastic nut on firewall stud, and lever front edge off with screwdriver, attached in 2 places.)

3. Pull off rubber door sealing strip to top of dashboard.

4. Remove glovebox, by:

a. Removing the 2 lower hinge pins (by sliding inwards to unclip). Partially remove the glovebox lid, being careful not to break the tension string.

b. Remove the screw at the lower RHS of the glovebox assy, as shown below.

c. Remove 4 screws along the top edge of the glovebox.

d. Remove the screw at the lower LHS of the glovebox.

e. Disconnect the Glovebox-light cable, and remove the entire assy. The car should look like this now…

f. Remove the black spring clip on the lower edge of the white vertical filter cover, and gently lift the cover upwards.

g. Remove the 2 panel filters by sliding out the lower one first, and then the top one will fall down.

h. Remove the white fibre concertina element (dust filter), from both panels, gently clean with compressed air, then wash in hot water and detergent.

i. Remove the black honeycomb element (deodorising filter), from both panels, and very gently clean with compressed air only.

If you clean these elements carefully, they can be reused, as I would hate to think what a replacement filter would be worth.

The filters on my car were absolutely filthy…a fine specimen of the air quality in Tokyo I suppose!

Assemble parts in the reverse order, but pay particular attention to the alignment pin above the screw, on the lower RHS of the glovebox assy. See Fig 1 above.

As with all plastic parts on cars, don’t use excessive force to remove or replace them.

Hope this helps any fellow R34 owners.

Regards,

GK.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      MR HAMMER has said his piece. Painted up to avoid Rusty Rusty. Actually lines up well. (i.e it lines up the same as the unmolested GTR guard). Turns out the GTR Strut brace does foul on the bonnet vents ever so slightly. May need a little bendy bendy if intended to keep using with a strut brace. So spacing it out to clear the FAST102 is not an option. Annoyingly, the bonnet vents also foul on the heater lines running over the engine. Given this engine does not EVER require a heater, a delete loop is going to be used. Don't worry, the defogger uses the AC. The heater is basically "Do not use the aircon and turn the fan on". It will still be effective, I promise.... once I get the system regassed... Will have to revisit with unvented bonnet I suppose, and suitable strut brace. There's plans to do this and other things tonight and bleed brakes (there was a weep) and put the bumper back on, and take Good Friday morning - Because troubleshooting on the side of the road limping it home at midnight tonight is ... not very smart.

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      Thank you all for you assistance. I contacted Nistune regarding the support for the RB20DE along with my ECU Code (23710-10U00). They do have a map for it and added the RB20DE as a purchasable option now as well. They also added Malta as a Billing and Delivery options as this was missing. I was honestly amazed at their quick response and action, it took less than 24 hours. I also looked again at direct fit options for injectors, just in case I were to replace them. DeatschWerks seem to use a Bosch EV14 base and makes ones that fit mine at 440cc lowest, but also have 550cc at the same price. I tried looking for other direct fit options and managed to find one (also Bosch EV14 based) which includes a plug and play adapter on ebay. Did a small test with a Noid Light on the troubled injectors and all seems good, so they are pulsing properly electrically. One weird part is that they are missing on the same two cylinders as before I got the injectors cleaned. Mechanic also found this weird as he did not label the injectors and it is unlikely to have the faulty injectors be installed in the same cylinders.

      Put a hand on an injector and see if that's what the buzzing is. You might be triggering the injectors by moving off idle command.

      Ah, should have been clearer. Currently has a flex sensor installed all good to go.    like u mentioned, I’ve only ever known the car on e85, I might hate 98, but I have to try it out first. Everyone says the -5 turbos get pretty laggy on 98 octane tho…
