Thing looks clean sir. How much extra scoot did the DASC add to the m44? is it on the m42 now

What type of numbers did they put down? There were several people who did the 327i non SETA conversion on e30tech when I was on that forum 10 years ago and they had issues with rough idle and prolonged cranking on startup until they put megasquirt in it. IIRC they put down ~130-135whp and ~140wtq with aftermarket exhaust from the manifolds back, cai and a Dinan dme chip. My b25 dynoed 152whp and 144wtq with very similar modifications.

Just seems like a lot of work for no gains, but I am looking at it from the angle of having an i to begin with, not an e.

Some started with I's others started with E's. The "weakest" of the swaps came in around 160whp 170wtq with the strongest being 163whp 175wtq. It's not really not the horsepower gain it's more of the torque and how much lower it most of that torque kicks in on the powerband. A friend of outs who sourced a SETA bottom came in at M50 power numbers of 175whp 185ish wtq

160whp is stock m50b25 power. 175whp is m52b28 territory. Those numbers can't be with the stock i cam and exhaust manifolds. If they are, that is astounding.

Or just properly maintained people are shocked at what a properly maintained car can run. fresh plugs no exhaust leaks. They had exhausts however that can make a slight difference but still.

I don't know exactly. I think it had 225hp maybe? Plus it was much lighter than an M3. I could be wrong on that number.

And nope, sold the DASC with the car.

This! Friends always ask me why my car is so snappy (throttle response wise). It's not really modded at all. It's because of how it's maintained!

When I picked this example (zhp) in my sig up it was incredibly slow. I wouldn't be surprised if I added 20hp or so through tune up stuff.

Perfect example I just swapped in a "fresh" engine. My last m20 had about 340k when the piston rings decided life was not worth it anymore. I just installed a lower mileage m20 maybe 140ish k did a valve adjustment, timing belt and fresh plugs. Now she scoots around eagerly again.

Until the chain guides disintegrate and the profile gasket blows.

I bought a blown 318ic and did a swap to an M20. The chains guides fell apart and locked the engine solid. The swap was pretty easy, though. The M20-powered car was a blast with the huge final drive ratio that was necessary for the m42 (so it would get out of its own way).

I'd rather rock an early M10 version of the four. It was rock solid reliable. I have seen too many blown m42's to ever want to go down that road again.

By the sound of it... you never had an E30 with a working M42. The chain guide is the crutch of the late 318s, luckily it can be fixed. You can hear it as they start to go bad, and then it's a cheap part and a lot of work to fix it. It's no reason to discount the engine.

And choosing an M10 over an M42 is simply ludicrous.

It's basically the amount of effort of doing 5 timing belt jobs in one

But really Changing the timing chain is kind of a standard now especially if you swap in a M/S5X motor or even a larger and much more notorious M6X motor.

I know I helped do an M60 and now an M62 timing chain it's fun

the M42 is a fine little motor it's really a matter of character preference. Do you want more low end grunt or would you rather keep it screaming.

If you chose an M10 it's because you plan to dump ridiculously abusrd amounts of boost in to the car as that iron block is indestructible.

I bought a pristine one-owner starspoke-shod '91 vert from its original owner back in '96. I drove it for a few months and sold it because it was gutless and sounded like a blender full of rocks at wot.

The m10 was a real pos. That's why BMW used it as a base for their turbo'ed F1 engine that pushed more than 1000 HP in qualifying trim.

He might get close to it...If the buildis as properly sorted as those parts appear it's a solid car.

That front mount cooler looks like Bane's mask or Darth Vader
