Not really. They go back in their because it was the easiest way from factory.

It's a proven advantage to vent them somewhere else. My RX7 has the breather go into a bottle... The optimal setup is a 2L+ bottle, with steel wool baffles and a drain back to your sump.

Oil vapour = lower octane of your fuel and grime up intake. Which we all know is an issue on VQ motors. When I ripped off my intake it looked like someone had poured a bottle of oil through the intake. (Given it probably had never been pulled off its whole life of 200,000km)

Yeh, i'll probably do that, or just get a silicone joiner the same as the black pipe, just a little more dollars.

Just to agree...

They go back in there because it is part of the 'environmental protection' of using all vapours through the engine etc.! Even fuel vapours that come out of the charcoal canister get re-used into the engine.

Optimal setup depends on your sump size, what boost you are running (which to some extent has an effect on blow by) and how efficient the scavenging of the 'catch can' is. Draining back to the sump is good, but you don't want to pressurise your sump, so use suitable PCV valves, and vent the 'cleaned' air back into the factory position. Then less oil gets into the intake and you don't increase your chance of detonation.

The S14/S15 SR20DET has a great factory 'catch can' built into the rocker cover. The design means most of the oil gets returned to the sump, and it still vents back into a 'factory position' after the AFM and before the turbo. Works excellent.

Yeeep. I'll probably just end up getting a nipple put onto this intake, as i'm not after performance on this motor.

Oh and this afternoon got bored, so pulled some peices out of the interior and washed it all. Pulled seats out and vacuumed, cleaned up amp wiring and put it under the boot floor.

So gross what appears over time, the cup holder in the middle was a mix of tobacco and sticky spilt Rockstar/Monster, including under the slip-in peice.

Fitted the throttle body... redet the ECU.

Car wanted to stall a few times on the first drive, but after restarting the car it seems good. Drove around this morning for a bit and no 4wd light yet... which is a good sign so far. Fingers crossed.

Hows your idle? Steady at 650 rpm?

Big day today.

Headed out to AM Performance, who are planning to start producing M35 exhaust systems. Donated my car as the development car, should be getting underway in the next couple of weeks.

Then headed around to my dad's workshop and put the car on the hoist for a service. Was very interesting, gearbox and engine took no where near as much oil was I was expecting even though they were drained.

Have found a couple of things that need fixing through. Rear disks need machining and rear pads need replacing, and need a catch can. Couldn't find any reason for the weird noise that I get occasionally when I lift off, so sounds like new blow off valve too...

And after all that, I forgot to put on the intake spacer I got from Craig! :domokun:

Edit: And no bloody LSD!

removed front bar and rewired the botton foggies in my aero bar back together as they were cut for compliance reasons. for such a simple job took me about 1.5 hrs inc removing and reinstalling front bar.

do you reckon the little "plug" in line with the OBD port maybe eff'd?

anyway attacked my belts today. pulled em off Cleaned off all the belt grip shit with some degreaser and a scrubbing brush! put new belts on, the squealing seems to have stopped.. hopefully stays stopped

Thanks scott for ya help!

    • Nah that is not actually a lot. Just painting my GTR frontend and the little bits to make sideskirts/nismo flare pieces work correctly/fit on the sedan/mount up correctly came to about $7000. Is it a lot? Sure. None of this is economical. Economy would be shelling the car and buying a 2010 Corolla to commute in. The perspective of all of this is different.
    • I have the re003s’ on my 06 XT Forester Turbo and I highly rate them for street wet and dry
    • I don't see any issues here. I've been saying all along this is a big job, the price reflects that.  When the car comes back perfect I'm sure it will feel like money well spent. 
    • Remember, take original quote. Double it. Then add a bit more. It's how any project goes.
    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
