DTR's Turbo'd M52 E30 track/street Demonstrator

Hmm.. maybe ill do one. But I have a cat tho. Youre saying its ok to do it pre cat? What if I have shit loads of blow by? lol.

Might be bad if you have lots of blow by, but a good breather system reduces blowby. One of the great benefits of this system. It is ok to go precat though. I would do a cat test pipe dropout... use cat when you need it.

I have a bolt on cutout I use for the track. bypasses the cat and such. But driving it places, I keep the cutout capped. Sorry to bug you about tons of details. I might hit you up for part #s and such when I'm ready for that breather system (EG check valve, piping size for the nozzle to the DP, good enough for the temp hose).

[DTRguy]

Just do a cat test pipe and pull the cat It's what I would do. AV12 is the breather I use... just match up the pipe threads to an appropriate stainless nipple (I think it's 1/2" NPT) and put it in at a really low angle (best if in a bend at the heel). I usually weld an An fitting to it and use a braided an12 hose. There is quite a bit more that goes into it to make it work correctly so many times people do it wrong and it doesn't work.

Here is one example that is almost done (in pic almost done... car long been done)



Here is another on an Audi A4 that I did... the valve was removed... but you can see the nipple. Both work really well on their respective cars.

Getting kinda redundant for me to post up on multiple forums... I will keep this one somewhat up to date for those that don't go there though. ;)

Well today was a busy day... since I am awaiting materials for other things... I thought I might tackle the fuel system (or at least get a good start on it). I've had this idea bouncing around in my head for a while so I decided to start on making it up.

I won't bore with details... I'll let the pics describe what I am doing here:









Because you never know when you need a spare tire and can't get any other

Obviously I am not at all done... More to follow
