You can buy the HPF manifold from the supplier direct for $1,500. http://www.steedspeed.com/bmw_e46_turbo_manifold

Wouldn't be able to use the stock DME alone, and balls aren't required, lots of money would be.

Why bother, put a Motec on the car and be done with it. The factory DME is a great ECU but will require some sort of piggy back just as the HPF kit did, there are plenty of people with balls enough to make it happen, just a matter of someone bringing a wallet big enough to make it happen. I could deliver a kit for the car no problem at my shop, just a matter of someone paying for it.

It's a standalone engine management system that is custom tailored to do whatever you tell it to. Common in almost all forms of motorsports. Basically for a system like this you would build a custom harness and have the Motec wired in as a secondary ECU to control fuel and timing, while allowing the factory ECU to handle the cars drive ability features. It's not as easy as it sounds, but very do-able. I have a Porsche and Lamborghini Twin Turbo running on this system now, getting a Z4M shouldn't be that difficult, just a matter of it being worth the investment (4-5k on the electronics side in addition to the turbo kit itself.)

HPF uses a similar setup in their kits, only using an AEM box (which in the past has been quite a bit inferior to Motec in terms of hardware quality). That being said an AEM or any other standalone given the outputs and inputs can be configured to make it work with the proper time and know how invested.

It's what I have been telling you, it takes money, can be done, but takes money, more then anyone here would pay.
The development just to get any management system plugged in is huge. THere are tons of "roadblocks" just getting vanos tuned is a absolutely massive undertaking, you're talking thousands of maps. You're talking 100ks in development.

More tuning options, its defiantly a pricey system but they have plug and play for s54.
I know our ecus are different but i would imagine that the harness would be same or require minimal changes to suit or cars. Vi-PEC V88 plug & play E46 M3 MS54 standalone ECU available through Apex Speed Tech Quote:

I know, but i think most people know of good tuners. The bigger problem is having something that can be tuned.
Vi-pec could be step in the right direction and be a little easier then custom wiring a motec or similar. I cant find any info on piggy back set ups with our dme, also cant find much our on s65 and s85 ecu options. Thinking if there is someone running a piggy back set up on one of those engines then it should be possible to do the same with ours which would make things ever easier.

~4000 Z4 M's. The number and market simply isn't worthwhile. Any reason why the ESS VT2-500 SC kit wouldn't be adequate? I'm not the most well educated on the topic, but I'm not clear why you'd be willing to pay double for a turbo. |

+1. There is a proven SC system by ESS. Why bother with turbo? Not to mention the turbo lag etc...

You would have limitless options with a turbo kit. What size turbo you want to run, what type of boost levels you want to run, how much power you want to make.
Then you also have boost control, boost control per gear or rpm, launch control ect Stuff you cant do with the s/c kit because its boost is directly proportional to rpm. You could also make more power with equal or less boost compared to the s/c kits. As for lag i think you could make a pretty decent single turbo set up with next to no lag. Not that im thinking of going turbo - but there are advantages and i think if someone does make a custom kit it would be a great project to follow.

Personally I believe it will, but there's no way to be sure, and HPF is not prepared to sink the money necessary into it to find out if it will, especially with the very low potential for selling many kits.
