BMW 2002 Homemade Turbo Build Thread

Re: BMW 2002 Homemade Turbo Build Thread
Threw the fuel rail and injectors on.
The 318i water temp sensor housing with all the extra sensor goodies. Threw a ground cable on there too for good measure.
Snaked the megasquirt harness through the hole in the firewall, to see how much room I have to work with.
Hooked up barbed fittings to the oil cooler
Also teflon'd up my oil feed fittings to the sandwich plate. I blocked off the other ports.
And tightened on the sandwich plate to my oil filter housing.
Cleaned and prepped the head & exhaust manifolds for assembly. I used parts cleaner to clean both mating surfaces then some high temp copper gasket maker ---- I heard would work well at high temps and pressures.
And threw the exhaust manifold onto the head, bolted it up.
And threw the adapter and turbo on for clocking purposes.
And lastly mounted the oil cooler onto the front grill, the feed and return lines fit nicely through the slats of this rusty behemoth of a sleeper.
That's it for today, the heat got to me and made me quit. I give up for now. More work tomorrow, car WILL BE RUNNING THIS WEEK GUYS!!!

Re: BMW 2002 Homemade Turbo Build Thread
another update
note to everyohne who reads this: im verfy ------- hammere dright now, please excuse anyh errors i mayt make in my post.
dremeled out my manifold to turbo adapter i made:
Adjusted the vlavdes and threw the valve cover bac on... bunch of 10mm nuts keep it on and a 10mm bolt on the timing cfhain cover. used some copper permatex ----
Then taped up and split my megasquirt harness into 3 pieces. One for the injector system, one for the ignition system, and one for the sensors.

Strip the wire on the injector connectors, the red wires will be split into 2 pairs, with a 2 amp fuse on each pair of injectors. 1 and 3 were on one set of wires, 2 and 4 on the other.
Since I opted to use a switch board instead of a relay board, the extra relay harness wil be used for switches.
Hook up 2 injectors to 1 pair of the red injector wires, and the other 2 to the other pair for the positives. These will go to a positive switch block to bypass any relays, each pair will have a 2 amp inline fuse.
Since I can't hook up the 255walbro directly to my fuel feed due to the danger of sucking up air and leaning out, I have to make a seperate tank in the engine compartment with a low pressure feed pump and a high pressure built in walbro with a fuel filter sock. I found this container off a copy machine at work, figured it may work good enough. JB weld was my friend here.
Drilled a hole in the side of the conainter for the gas return,this will go back to the existing fuel return line to keep the tank from overflowing.
Drilled the holes for my EDIS4 module attachment, on the front of the firewall by the windshield washer nozzles.
Then rewrapped and ---- the existing wires on the car that have nothing to do with my standalone. But they were pissing me off and didn't want them to break or ---- up so I did some work on those.
ok, not gonna liem., too hammered to go one
going to attempt to start the car tomorrow, will keep u guys updaated as Igo tomorrows the big day. Hope it works, gotta hook up the ignition module and all the other good stuff. Tap into oil pan for the oil cooler and turbo return lines.
Sorry for the shitty drunk update post

Re: BMW 2002 Homemade Turbo Build Thread
You basicly made a surge tank. Ideally, the fuel rail would return the fuel to that tank, with a slightly higher 'vent' (high drain) that will return excess fuel from the surge tank to the gas tank. I would be surprised if your old stock fuel pump has a higher flow rate as the 255 pump. Remember that it moves enough gas for ~550whp, whereas your 2002's pump probably pumps half that, if even close to that. I'd guess your surge tank will be empty by the time you crank the motor over...maybe longer if it only primes for a fraction of a second.

Here's another update from today.
A big ol pile of ---- on the roof, more wiring and hoses:
Home made mods to a DSM 10psi wastegate to replace the 27psi wastegate that came off the isuzu turbodiesel turbo.
And the obligatory HMT part of my turbo setup to make a fake wiener while I hold it and have one of my friends take a picture of me.
Tearing apart the wiring harness and soldering up all the connectors, I hated this ---- so iI had a friend do it.
Tapped my timing chain cover for oil return lines from the oil cooler and turbo.
Still a ------- mess of wires, slowly getting sorted out.
Took out my windshield washer fluid reservoir about 6 months ago. Figured hey might as well use it for something, so put my fuel surge tank there in it's place.
(Also painted it blue for 30 extra horsepower)
Got pissed off that I'm missing a few pieces still, so I called it quits and hoping to finish tomorrow. Almost done!
