That's a really neat and tidy car.

Have you thought about butchering your bonnet with a Subaru style air scoop?

[Oink]

Yeah I have, previous cars have been wrx's so I initially thought of a wrx scoop to replace the weird factory ducting
I would go down that path if I could source a cheap enough bonnet to try it on, as I am not keen on stuffing up the only bonnet I have.

[Oink]

So next question...anyone have a spare 405 bonnet for cheap?

Slug II?

The takanini 405 has had a frontal collision.

Havent been to the Avondale yard yet though.

One disadvantage to running the oil catchcan - you can now get wiffs of oil smoke coming from the filter when in heavy traffic.

There's a guy down the road from me selling a bonnet in white if that's any use.

[Oink]

Where abouts are you? Auckland?

If I could get a white bonnet that would be primo

Towel wronger.

[Oink]

Argh, righto then...

Bit far for me at the moment, will see if I can source something local first.

this is awesome. more people need to fettle diesels in nz.

for your breather: you could now re-route the breather into the intake after it goes through the catch can which will catch the mist, and jsut leave the smelly air to go through the engine?
altenatively, while you're building a nice, back pressure free exhaust, you could add a barb which the breather will hook to on the exhaust pipe somehwhere.. pipe ot from the catch can to the exhaust. if you build it right, the exhaust flow will cause a small vaccuum effect drawing the fumes out

I'll try find a pic of someone that's done it.

[CaM]

you wouldn't need the little one way anti-backfire valve. diesels don't usually backfire
this would really only work if you built a nice zero backpressure system

I think going 3" exhaust is a little overkill, too, with this thing. if you upgrade the turbo to a t3 thing then it may be of some merit but for the tiny stocker you'd really just want to update the dump pipe and add maybe a 2.25 or 2.5" system for max win.

[cammmy]

Add merge downstream from churbo could help negate back-pressure issue?

[Oink]

It may be a bit overkill, but after the noticeable difference between muffler/no muffler I want to free it up as much as possible.
3" will allow me to run a bigger muffler without too much restriction.

Plus I can get 3" pipe for next to nothing.

I have run a 3" exhaust on a 1.8 petrol before (That was running 350hp though) so I thought that purely for exhaust flow - I would give it a shot.

Although looking at the sectional area of the different pipes
2026mm² 2"
3167mm² 2.5"
4560mm² 3"

The 2.5" increases the area by 36%
The 3" increases the area by 52%

So although it may be overkill (most likely) I am not going to lose any gain from...so why not give it a go?

[Oink]

I am not that keen to hook the breather back into the exhaust.
Reason being, I am just not comfortable with exhaust fumes/particles possibly been able to go back up through the catch can and introduce more pressure into the oil. But that is just me...

I could do it with a valve type arrangement, but that surely bypasses the whole point for having a breather tube, i.e to release crank blowby when it happens.
