190 E BUILD!
On test drive car was able to achieve 25mph for about 2 minutes. It is leaking coolant badly! Also transmission does not grab gears.. Reverse and second gear work.
Plans for paint, evo II kit, new motor/ tranny/ rear end, soon!

Parts wise, some are ludicrously expensive, while others aren't. There are loads of these cars in Europe that are still used in racing, so you can find a lot of parts if you know where to look. Atec Motorenbau (http://www.atecmotoren.de/) still supplies a lot of DTM parts (intake, standalone ECU, suspension, etc, etc, etc). David and Thomas are very helpful.
These forums are very good resources:

You have to remember with these 190s, that handling was the big issue. They were built to turn, and they do it very well. What's sad, is these cars are almost worthless these days, so everybody starts throwing LS motors in and effectively turn them into backyard hackjobs.
If you are looking to use it as a fun street car, I would say shoot for about 250hp and start lightening up the car. Ditch the heavy stock seats in favor of Sparcos (or whatever brand you like), run 17x8 or 17x9 wheels (Enkei's tend to be very light), H&R cup suspension kit, find a nice muffler you like, and enjoy it.
I'll send you a PM with some of the parts prices for the 2.3 cossie motor. I'll have to dig through my old emails to find them.
Cheers,
Ricky

I only have a modest working class budget to work with but plan on spending a bit for the rest of the year and get it up to scratch. First up next is changing all the fluids/filters. Last owner overfilled the oil a bit (it's blown all over the engine but doesn't drop any on the driveway, a good clean and oil/filter change should do the trick).
I do want to attack trying to squeeze a little more grunt out of it if I can, bring up the paint real nice, look at taller rims and sexy tyres a little later.
The M-103 sounds tricky to get much more out of without throwing some big dollars at it with blowers and the like. Stock they're already putting out 1hp/cubic inch which is real impressive. Other than freeing up exhaust a bit I'm not sure if there's much more I can do on a budget. Head must be breathing okay to start with, valve timing is already up the range at 3800-5800, induction is fine and it gets plenty of fuel and plenty of spark. Compression is good for premium unleaded. I think anything else to do for more power is only going to make the returns higher up the range which I don't really need, it's not going to help it in general touring on the roads.
Unless anyone here knows any secrets to the M-103 2.6 I guess I'm sort of stuck other than the cleaner exhaust, until I can afford a kompressor (I can play with cam grinds to bring dynamic compression down a little for a low booster, this works if you don't go silly and I can map it all out on some software I have).
Seems to be the only way I can imagine to crack 200hp which is where I really want an engine in this car, at least, without an engine swap which I don't want to do.
I appreciate engine swaps, and the M-103 comes in 3 litre I've noticed but I'd really prefer the original 2.6 with 200hp than an engine swap to do it. Guess I'll have to weigh up if a kompressor or engine swap is cheaper. But I like the little six.
My build is the slow road, a piece by piece rebuild each pay. I just put new brakes in this week. I'm still being impressed by now securely and comfortably these cars drive. Getting more familiar with it I'm finding pleasing results, it seems to have an LSD I found this morning when I tested low gear acceleration onto a wet causeway. That was a nice surprise being I was able to bolt into traffic very tractably when I was expecting nothing but wheelspin, as I discovered the merge lane was so slippery exiting. If that's not enough the rear suspension beautifully soaked up roll rate and prevented fishing with barely a moment off the power and near maximum acceleration. Potential emergency averted with ease, seriously these cars are safe!
I actually managed to find a German tune shop that sells off the shelf performance cams for the M103 and am absolutely thrilled. I got a referral to a local fabricator who can custom build me a tubular extractor manifold with nice square port exits and decent length primaries...well as much as can fit in the tight bay anyways. Between the two it'll cost about 3K but with good plugs that should get me closer to my 200hp ideal whilst keeping the original 2.6 litre engine...well probably more like 185hp but I'm good with that.
It's not like I can financially compete with serious Merc tuners anyway, but if I do it with intelligent parts matching and plenty of hand finished quality work, at least I can have a quick 2.6 that people don't really bother with, but could surprise a few.
And the whole thing is still costing me only a few grand done. Bargain of the century.
