I'm wanting to turbo my 316i and I was just after some advice on things like

Manifolds
Where to get the oil feed
The best turbo to get
Management
And running standard injectors
Before its suggested I don't want to put a 6 pot lump in I love the idea of a 1.6 turbo. I've tried finding a build thread that goes step by step but haven't managed so I decided I would just ask.

1) build your own
2) oil filter housing has a Allen key bolt in, remove it and use that for feed
3) maybe something like a impreza turbo or turbo from any other car 1.8-2.3litres
4) I used megasquirt but almost any will do
5) you will need bigger injectors

What injectors would you advise CHU? I need some for my S/C build aiming for high 200s-300

My brother's M40 is at 313whp. He changed cams, 440cc injectors, Vems ECU, Evo9 turbo, welded the manifold himself. He made an oilfilter cover that he took oil from, and returned it to the oil pan. De also did some other things, if you want more info. send me a PM.

I used some volvo 32lb bosch injectors form ebay. I was maxing my injectors at one point at around 230bhp. If you want 300bhp you'll need to go 50lb+
