I have a 06 325i w/ 3.0 215hp. My brother has a performance shop and has a fabricator. I'm trying to build a turbo kit for my car but I need someone with experience w/ these cars to lend me a hand. Keep in mind I'm developing a kit to be reproduced. I need the nity gridy about these engines. Who has tried stuff and blown headgaskets and crazy people like that. B/c when building a kit like this I need to know where these cars start to fall apart. I need to know there limits. Whats the compression ratio on this motor? How much torque can the stock tranny handle? How much power can the engine handle? What is the output of the injectors? Can a technical person please share some info with me? Thanks in advance.

Are the heads the same, the block, the internals, how do they differ from the 330? Can you bolt a e46 head on an e90 engine? These are all questions I need answered.

[ddigangi]

here is some technical help

1.) take 3 series engine (n52) and remove from car

2.) place 335 engine (n54, twin turbo) back into car

3.) smile cause now you have a turbo ed three series

s54 > n54

n54 is a pos

I trying to develop a kit for those that can't do a transplant. There is no imagination on this board.

What you're trying to do is a bit of a challenge. No one makes a viable aftermarket kit for the NA E90. ARMA has some sort of kit but rumor is its going to be around 12 Gs. Most people on this board will tell you to trade in for a 335 or do some sort of swap. For most people this isn't possible. They're into their car for a number of reasons. Keep that in mind when more people start posting. If you are successful, and can produce what some consider to be an affordable kit, you will have truly accomplished something. Good luck.

lol, unfortunately this isn't the ls1 board. Anyways, from what i understand forced induction and figuring out how to make vanos work with it is the big problem. But the cost of a turbo kit is another issue. Not many people are willing to pay 12k for a turbo kit when you can just trade for 335i. Build us a 5K supercharger kit and i might buy it.

All of that will not be necessary if you cannot tune your car. If you are serious about this forget "pushing the limit" and just get a concept that work. Just strapping a turbo on the n52 will net you absolutely nothing. Find a good tuner and build the cheapest kit possibly. If you can get it going then worry about all the nitty gritty tech stuff

[turbodrive]

are there anygood piggy backs or plug and play stand alones availible for this car?

[ddigangi]

BMS power box.

[turbodrive]

is there anyone on the board that has used this product? How do you like it?

[turbodrive]

after reading up on the bms. It's very limited due to the fact that you cannot tune your own car. You can only use the tunes that they give you.

[turbodrive]

btw this is my first bmw. Whats the difference b/w the 330 and the 325 besides the hp and tq?

[turbodrive]

are there any programmable piggy backs out there?

[turbodrive]

correct me if i'm wrong, but i beleive the aem fic should work on these cars. Can someone confirm?

the main differences are the intake manifold and the software programming. Otherwise, the mechanical aspects of the engines are identical. As far as a piggy back system, the BMX is a closed system to the end user. I do know that Terry at Burger Motorsports talked about the possibility of releasing a model that could be interfaced with a laptop and tuned, but it was just an idea at the time the bmx was released. At this time, it's not a device that you could use for custom tuning.

A stand alone system like an AEM EMS would most likely work, but requires more labor (all custom wiring and sensors, iirc) and also much more cost. check with Craven about using gintani to tune the dme. That might be a more economical route.

You biggest issue will be the tuning which I am working on now.

Maybe we should talk on PM
