I think you are using the SYNAPSES waste gate(it look really nice isn't it)
I have bought it also for my turbo project. I am waiting for my cherry bomb resonator & muffler so next month I will start to put it in also .

Haha yeah it sure will be. Although it's down to the bear shell it still is a very heavy car.
I'm just a little disappointed to know that they don't have LSD diffs which limits a whole lot of fun.

Yes it sure is, I've heard good and bad things about them, but when I have the engine running I'll see what's like.
Good luck with your project will be looking forward to see it.

Could you give me some advise about the PCV sytem
How are you going to deal with all of the PCV on the engine?
IFrom what I know M104 have 3 PCV routes
2 vents on the valve cover
1 tube that connect to the center of intake manifold

I have wandering web after web
but there is no specific answer or picture of how people fix it
how to route the line to a catch can

I wish you could give me some advise
I keep on asking about this question but no one seem to
explain it completely

Thank you very much

Well Ive actually kept them as they are, and my M104 has only got one breather vent on the valve cover and that was routed to the throttle body originally and because I've changed the throttle body I've just rerouted it to the intake manifold.

hope that make sense.

From what I read you may need to put a 1way check valve on that tube
to only let the vacuum from the intake suck the gas in
but not allow the boost to push the + pressure back to the crankcase


According from what you said
seem like I already find out all of the PCV on my engine
Big thanks buddy!

oh yes the check vavle is a must.
no problems

or just don't reroute it back from the catch can to the intake pipe , vented to the atmosphere or put one of those small filters
