Do you have the attachment that connects the box from the RHS into the guard?

If its the same as the 34 GTR, there will be a cover on the inner guard side of this attachment. You can take this cover off to increase air intake.

Power level is 422rwks, on 19psi.

Just changed to bigger twins and want to chase 450+ rwks

Why does that matter??? I just want to know how to modify the thing

So you're making 422RWkw with a completely stock airbox? - Good to know!

Yep removed that already, anything else I can do? :)

Hmm I might be able to cut out a much bigger hole and a custom larger pipe into the guard :)

I found that the stock airbox was becoming limiting around 500rwks so I need to custom make something however still need to retain the standard appearance :)

Whats your current power level and mod list?

It may matter to you that Piggaz car has made a genuine 470rwkw with a standard box and NO modifications. So he MAY have saved you some time and energy

Trent's dyno isn't accurate, because it isn't in NSW. :P

Daz at this power level you won't get much help from these guys, how many have cracked 500 let alone on the stock airbox, piping and cooler?

The engine side of the gearbox you can modify that to accept a filter then modify the snorkle to feed air over it. It ain't a 5 minute mod though. I don't know the part number for the filter. Haven't gotten that far.

Also tickle the alloy pipes that bolt to the comp housings. I've sent you those pics before I think.

    • Good tips, will get on those tomorrow. When doing the maintenance I did move a few of those connectors around, and things that are old tend to not like moving around. (Like me).
    • Don't try it. It will be shit. Better chance of damaging the engine than gaining any knowledge about the old one. Maybe, but unlikely, especially if the O2 sensor is working. You can use NissDataScan to look at the stock ECU.   Cleaning the AFM is seldom necessary and seldom helps. The R35 coil & loom conversion should eliminate dud coils or plugs. But as you still have misses - look to the plug where the coil loom connects to the engine loom, and the CAS plug. Need quality connections there. Also look to injector plugs. And the AFM plug while you're at it. Also look to whether your injectors are clean and flowing evenly. Get them out and onto a testbench.
    • Good to know, I feel like I am in for a rollercoaster ride that looks like a sine wave. 
    • You'll fit right in. Acceptance is the first step.
    • Hey folks. I've been lurking and browsing the forum for a while, since I got into my head that I wanted a skyline. Having purchased an overpriced completely stock GTT, (only "mods" it has is HKS pod filter and catback) now that it became legal in the US, it was all glorious and sututu noises here and there. But then I wanted to do things right and went to do basic maintenance. After all the fluids, filters done, I did the spark plugs, that's when the problems started.. First the car started spluttering at around 4.5k RPM. Which I gapped down the new plugs and that solved the sputter there, but the car now always misfires at idle with pops when lifting off and shifting 2nd to 3rd. Similar to the issues in this recent thread. I've been banging my head against the wall, reading the threads here and trying suggestions for a couple months now, so decided to start this one to explain exactly what I tried and what is going on. The symptoms of the issue: Idle and low revs misfiring intermittently. You can hear the exhaust tone change and the shakes on the shifter knob. It happens frequently, but doesn't seem to have a rhythm to it. Pops when backing off throttle. It pops and or burbles almost feels like it spits fire when it pops. (Happens mostly in 3rd gear at around 2k RPM). When under load and after 6k RPM, it also pops when shifting from 2nd to 3rd. There's a ticking noise at around 2k RPM in 2nd gear going downhill, seems unrelated though but I am out of educated and downright dumb guesses. Not noticeable lack of power when putting the car into load. The attempted diagnosis and solutions: Unplugging coils when the car is running This did nothing to change the idling and tone shift for every cylinder. Checking the exhaust headers with thermometer They all are within what I'd say it is margin of error of the laser thermometer New spark plugs Tossed two new sets, copper, iridium and using the old ones, still misfiring, even re gapped to 0.8mm, still same thing. MAF cleaned with the "specific" spray cleaner No changes in the issues what so ever. Brand new loom and r35 coil conversion (was going to add the r35 coils anyway) car runs arguably better, still misfires, but seems like does less frequently. Placebo? Code 21 now being thrown, thanks nissan gods. Removed the CAS to check the shaft for play or anything. CAS seems all fine, nothing that indicates any issue, visually speaking. Things to attempted next: Ordered a new MAF (chinesium from Amazon, to be able to return regardless of result). Fuel with proper gas, maybe it is this California water that they sell as gas that is to blame? Plugin the link ECU and check the info using the built in base map. Go back to BMW and eat my rob bearing breakfast without milky oil mixture.   Do any of you have experienced anything like this or have any suggestion?
