Hi Guys

Looking for some advice with regards to the restrictive airflow on the little also. The air flow comes in from a tiny little inlet at the bottom right of this pic and seems to have a wild time before getting to the Turbo

So I was looking for some advice on this, this cant be good? Must be super restrictive. So, first of all I remove the first set of pipes so it starts at the airbox inlet. But I was thinking of two things:

1. A cone where the airbox connects
2. A cone but move it to the left hand side closer to the turbo
One issue I have is that there is a second pipe entering/leaving the airbox currently, from what I can see of K6A cone filter kits, that pipe isn't there, so any ideas what I do with it? Wee pic of the pipe here:




Advice appreciated guys If I am wasting my time on this, let me know :p

The pickup point for the intake will be at the front of the car where it gets cool air. Putting a cone/pod filter in the engine bay will just suck in hot air and reduce performance. Mighty Car Mods proved it a few years ago. Standard intake systems are only restrictive if you're making huge power. Just make sure the standard filter is clean and you're good to go.

Thanks Brayden
The pickup is tiny, so I removed the inlet which was only a short distance from the airbox entry...  pic here, its tiiiiiiiny:




So, I think based on your advice I'll keep the airbox but just widen the entry point?

The intake entry only needs to be as wide as the inlet on the turbo, and on a standard RHB31 that's about 38mm.

Nice one Brayden, that's really helpful, many thanks

One thing that will improve performance is ditching the top mount intercooler for a front mount.
You might even have enough space to move the top mount to the front somewhere. The right location will reduce heat soak and intake temps. My front mount dropped intake temps by 40%.

Yeah, agreed. the current intercooler sits pretty much around the intake pipework so the easiest way would be to change the intake pipework for a more direct route which then allows for a bigger top mount.

I think its likely easier to just go front mount from the outset though

The size of the cooler isn't the issue, its the position. Any top mount suffers the same problem - it sits in the hottest part of the engine bay, on top of the motor and exhaust.

Can confirm. Air filter does SFA for power, general consensus in Japan seems to be that unless you up the turbo both exhaust and intake do very little. A pod does make very funny sounds though, adds extra fury to your car while going exactly as slow. I found a tiny pod at up garage for 500 yen and threw it on for a giggle(thus the terrible location job). makes hektic suction sounds up to 4k rpm and flutters on lift. But when I get tired of that the OEM box is going back on.
