Well I am a new comer to french motoring, although I guess it was only a matter of time when you have a french girlfriend...
Anyway I have tinkered around with a few jap cars in my time including engine rebuild/ conversions , suspension, exhaust fabrication etc. But now I have a Peugeot 405 1.9td that is going to be the focus of my attention for a little while.
Although it is not currently fast, I thought I would sign up here to see what others have done to the 1.9TD to make it a bit more fun. (TBH I bought it to get me to work while recovering from a motorbike accident)
On the list so far is
Remove muffler or replace exhaust with 2.5" system
Cold air box on left hand side of engine bay with 3" intake system
Oil catchcan in existing airbox location
Fiddling with fuel pump/ on boost fueling
Increasing the boost
Well thats what is planned anyway. If previous cars are anything to go by it may take a while but it will get done.
Thats me anyway (Let me in?)
Turbo diesel tinkering is ALWAYS welcome on Fast Frogs :)
Howdy
Yeah, come on in :)
Welcome.
The oil catch can sounds like a really good idea.

Welcome.

if it has EGR remove that too and clean the intake manifold of all the sludge that would have built up.
Love diesels.
Well ripped off the muffler the other day...
While increase is performance is quite something, the unwanted attention from the police is not as welcome.
Boost is coming on much sooner (feels like the car is ready to go and moving all through the rev range) and acceleration is much quicker.
As a compromise between performance and noise have just purchased a M&H muffler which should dampen the noise a little but still retain the performance (or most of it anyway)
Although I am starting to love the sound of the turbo spooling that you can hear through the exhaust now!
Have made up the pattern for the CAI out of cardboard, waiting for the filter and piping to arrive before cutting up the sheeting and folding to shape.

epic tuning!
Anyway here is the car as it stands.
Managed to weld up the exhaust, but it has quietened it down too well and has killed off a bit of the performance gain that I got running no muffler.
May look to replacing the muffler with a resonator instead to see what effect that has. Or alternative is to replace exhaust from the collector back with a larger pipe 3" pipe , depending on the cost of bends and pipe.

I missed this thread - dam - I fuckin LOVE diesels..
Am going to remove rear muffler on my BX sometime soon - looking forward to the power increase TBH..
How much louder are we talking? Did you remove both mufflers or just the rear one?
My 405 only had one muffler, a big chunky one about 500 by 350.
As to how much louder...um about 10 times louder. But you dont hear anything with the stock muffler on so thats not much of a comparison.
It sounds like your local bus/ 8 wheeler truck with the muffler off would be the best comparison I could give.
I'll do a comparison - my BX has 2 mufflers - one big and one small. Will peel off the big one and see how it sounds..
Ok, I have worked out that I can get 3" tubing for $9 a metre from a local yard.
With a reducer and a couple of bends, that still works out cheap enough that I dont mind doing it.
Intake all mocked up, just need to finish the box/shield which will be tight because of the engine pully.
Plus there is now room for an extra window washer vessel in the engine bay where the old airfilter box was located.
Which will be useful for an intercooler sprayer when the boost is increased.

That's a really neat and tidy car.
Have you thought about butchering your bonnet with a Subaru style air scoop?
(http://images.trademe.co.nz/photoserver/86/175719186_full.jpg)
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.
So next question...anyone have a spare 405 bonnet for cheap? ;D

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.
Where abouts are you? Auckland?
If I could get a white bonnet that would be primo

Towel wronger.
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.

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.
Add merge downstream from churbo could help negate back-pressure issue?
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?
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.
If you merge it at an angle the velocity of the exhaust gas prevents it from going back up into the crankcase. Another reason why smaller pipe could be a good idea is that smaller pipe = higher velocity = better vacuum on merge. I was going to say possibly better cylinder scavenging too but the turbo probably negates that.
If re-doing the exhaust you could go the whole hog and work in a venturi. Place the merge where the pressure is the lowest.
Either way it is a proven way to help reduce crankcase pressure.
I have this book:
(http://www.haynes.co.uk/Press/HaynesJackets/RGBhr_H691.jpg)
It focuses on petrol motors but there are still a lot of things in there that would be helpful when tuning diesel turbos. I would highly recommend grabbing a copy even if you have a lot of experience working turbo motors.
IMO 3" is still too big. build it with the right muffler and 2.5" will be more than enough. 3" is just a noise factory and you'll probably have trouble tucking it around everythign without having it hit the ground all the time :)
if you build it right and have no back pressure then there wont be any fumes coming bakc up the line.
just throwing ideas your way :)

Yes, this is all you need to do.
