Hi all,

I am going to be removing the heater core/complete fan assembly from my R34 GT-R and have seen that there will be four holes that will be left in my firewall...

What would be a good way to cover up these holes? Ie - Metal plates, heat shield material etc etc...? :3some:

I have attached a pic for your reference.

Thanks for any help/info!

what i would do :

use rubber bungs for the small round holes

then get 2 pieces of alloy cut to the oval shape of the larger hole - bolt them together through the opening so that it can be removed later. using a small amount of foam or rubber to act as a seal to the panel

buy rubber bungs from clark rubber, for the oval hole get a bigger bung, it will form to shape, exactly what ive done. works a charm

These methods sound good! Is it possible to get a photo of your setup? Would be greatly appreciated!

Thanks,

Get the ovals and circle traced and cut out of aluminium sheet, liquid nails in place to seal. Will be nice an neat. (I've even sprayed them lightly with bayside Blue :D

Nice job with the pic edit! See now THATs the sort of setup im after!!! Although i've never heard of 'liquid nails'... how do they work to seal the plates up?

Cheers

like silicone but better :D

just thinly apply to the overlap of the aluminium and stick in place over the lip of the firewall holes, will be very neat :cool:

If you can get the aluminium sheet cut as close as possible to the edge of the lipped section it will be fairly seemless.

What are you trying to acheive? Less road noise? Heat? smell?

If you just want to cover up the hole for simple reasons, use sound deadening mats... just cut and paste over the hole..

For more hardcore stuff you really should weld plates to it...

Actually, having said that you can also use thermal mats, (usually you stick this stuff around your turbo lines).. it will be pricey though.

Yeah thats not a bad idea too... hehe got a few options now. :D

Although im heading towards aluminum plates, but now have to decide whether i want to weld them or use liquid nails/sikaflex.

Cheers,

Glen

If you use sikaflex, make sure you get the heat tolerant one. There's one specifically for high temp applications @ bunnings.

Theres quite a few different sikaflex's... :blink: so which one exactly is the high temp application one that I should use?

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?

      Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
