My Ride: E46 M3 Turbo
My BMW E46 M3 Turbo RHD

Finally got it going again. Full aftermarket ECU now running the motor. Factory ECU is still in place and running the traction control, throttle and vanos.

Put it on the dyno today and found I forgot to replace the wastegate spring so it wasn't holding boost as you can see below. So max power was only at 11.7psi and tapers off from that.

This is done on pump fuel.

Dyno Dynamics 450rwhp = about Dynojet 510rwhp

Strong numbers, looking forward to when you replace spring and run 20psi. Congrats on RHD system

SMG or Manual?

I'd be interested in seeing the setup you have compared to HPF. HPF havent done a RHD SMG yet, they are doing one currently.

Good numbers for 11psi

This is on a manual. There is no reason that it wouldn't run on a SMG though.

Oh and it makes this power with a 3" cat in place so it's street legal. I'm pretty sure HPF run no cats. This also runs a smaller turbo and filter than they use just to make it fit in a RHD and just the factory fuel pump no extra fuel pumps to fail.

Hehe. There isn't that much to see really when the cars back together. The factory underbody brace still fits, all the standard undertrays fit back up. So once it's all together you would even have a hard time seeing that it's turbo from under the car. The only giveaway is the BOV on the plenum. Actually the only thing that can't fit back on the car is the standard fluid bottle for the windscreen washers. I could make up a smaller fluid bottle and get it working again but for my own car I don't use the washers anyway. It just gets the car dirty

But yeah I can take some pics to show you.

What have you done with the dme? You said it is still in place so what are you using for fuel timing control in place of it?

Why does everyone tell me this cannot be done? If all it takes is wiring in the AEM to control fuel and timing I will start building a top mount precision 67 billet setup tomorrow. I know everyone who works on these cars is trying to be secretive and make tons of money but maybe if you are somehow different you would be willing to let me know what box and what crank sensor and how you wired it up. ALso why do you feel the the stock motor builds boost too fast and you decided to build it, I want to run stock motor.

He means the turbo builds boost to fast, which that stock motor wouldn't be able to handle. That's really just an assumption or he has already had a bad experience and went ahead with the built motor. I am interested if he actually used the AEM emanage or the AEM FIC.

The stock motor has made over 700whp on more than one occasion. As far as I know these cars were stock motors including stock headgaskets. If you are capable of wiring in an aftermarket computer to control fuel/timing then there is no reason you cannon tune a stock motor car to make plenty of power on a 35r. If it spools too fast you can remedy that with decreasing timing. Maybe when he blew it up he had no timing control? The idea to build a low compression motor that spools slow was maybe a band aid fix at not having timing control. This is the only reason I can see for the theory that boost builds too fast. With a turbo lag is your biggest enemy when racing so the quicker spool the better.
