N20 Swap Anyone?

I like the look of the new N20. With 240 hp and 260 torque and only 317 lbs this little engine would sure be a nice addition to an e30. Has anyone done the research or considering? Other than a shortage of supply, is there a reason this can't be done?



"At 240 hp, the N20 develops 10 hp more than BMW's 3.0-liter inline-six in North America. It is terrifically refined and always feels urgent, with 260 lb-ft of torque on tap at 1,250 rpm. The power delivery is uncannily like that of a modern-day diesel, with particularly strong low-end attributes and impressive flexibility across a wide range of revs.

The six-speed manual version of the new X1 xDrive28i is claimed to reach 62 mph in 6.1 seconds, hit a top speed at 149 mph and boast a 50-mph-to-75-mph fourth-gear split at 6.0 seconds. By comparison, the current X1 xDrive28i sold in Europe, which uses a 258-hp version of BMW's 3.0-liter inline-six, posts figures of 6.8 seconds, 143 mph and 6.1 seconds, respectively.

Power builds in a smooth, free revving fashion without any hint of turbocharger lag. Work the N20 hard, and it revs happily to 7,000 rpm, although like most modern direct-injection units, there's a distinct lack of engine braking on a trailing throttle. The engine's powerful electronics package ensures maximum coasting potential is achieved by allowing the revs to fall away gradually. "

I heard from a friend that this is engine is quite a nightmare. His e92 is always in the shop and already has gone through a rebuild. Same goes with 3 other friends. Non of them race or abuse the car either.

The N54 and N20 both would be AMAZING in an e30! If only someone could figure out the wiring and software necessary to get them working.

^ Yes the software and wiring is intimidating. I know I won't be the first to make this swap a reality but I might be the second.

I suspect the HPFP and fuel lines would need to be carried over from the donor car as well as fuel tank modifications for it to fit. Some sort of cable throttle linkage too.

I'm sure with just a flash and all the components from the donor these will be quite easy.
Everything is vacuum controlled

The weight to power ratio on this motor is impressive, not to mention it will run the 15% ethonal crap we are getting to 2014. It would leave alot of room in the engine bay too.

I don't think that motor even has a throttle. Your gonna need the original ecu and someone with a lot of experience to modify it. Mark D?
