planin m42 turbo build
« on: October 22, 2012, 09:22:20 PM »
I have a white 91 318is. i was woundering if i could get some input on some of the things i plan to do in stage one ( if you will ) on my plan.

i'v been looking at a t3/ t4 turbo kit. I been looking at kits and forums and i feel like that my best option. 42lb injectors. on the stock rail or aftermarket rail i haven't decided. and upgraded fuel pump and fuel pressure regulator. I wanted to change my ecu with something tunable. so if anyone  has any input of this please comment.

The m42 manifolds are cast and weldable but I would start with nice clean alumium sheet.

If you can't afford $200 for a manifold, you cant afford to go turbo. Well, you can, but it will be cheap and unreliable. You get what you pay for.

Seriously, if you skimp, it will bite you.

Start off getting the car on a management system. Once thats solid, start looking at hardware.

The smart thing to do would probably be see how well the cast alum welds up, use a product like Protex or another alum cleaner to get it as clean as possible. It would save a lot of fab time BUT fighting dirty alum is bad and a big time waster, if any trouble then start with clean sheet. Do you have a water cooled TIG machine?
