That spot on the roof is common, and not really the sunroofs fault. E30's came with a stupid plastic slipstream deflector,and they all have problems right there at the corner that always trapped water...

I have a 160* thermostat in my m42 and just because it opens at 160* my cooling system can only keep my car around 180ish. On hot days on track my car idling with just the clutch fan gets up 185-195* I have to put the electric fan on get it to stay around 180* at idle when it is 90*+ outside. After hot lapping the car on limiter though I'll get up to 210-215* and it'll cool back down pretty quick. But at nights if I am driving down the highway I see temps of like 155* because of all the airflow.

I obviously don't have AC like you, but I would try and get some sort of slim pusher fan to put on the AC condenser to get more airflow through that thing when you're at idle. I find my car cools off the fastest with the clutch fan when I drive around track high rpm second gear since it is spinning faster. Also bummer about the roof rust I have a few spots on my car that need to be addressed soon as well which sucks.

Would you mind sharing your timing map? I'm going be getting my turbo megasquirt going soon and want to make sure it doesnt go boom.

It's not wise to just share a map like that and expect it to work on another car. Take your NA table and subtract 1 per 10kpa above 100 and you will have a safe base. That will put you in the teens at 200kpa which is low, but safe in both directions. There's a couple of threads here and e30tech where maps are shared, just beware. Some of those maps posted are 10-ish@200kpa which will create a lot of unnecessary heat in the turbine. Also, if you have a different base timing than them in your MS, you could very well go boom...

I understand. That gives me a base to start with thanks. At the moment I have nothing except for whatever comes pre-loaded on the mspnp2 ECU. Thanks!

No space. See previous posts with pics of the intercooler->condenser->radiator stack. There's about 3/4" in between the intercooler and the condenser and less than 7" between the top of the IC and the frame surrounding the condenser.

I'm not in the habit of sharing timing maps because they require a huge disclaimer. Too many variables. It's not hard to make a safe base map yourself as ForcedFirebird described.

Went to the second Spectoberfest at Sebring this past weekend, pretty good E30 turnout but mine was the only turbo E30 present this year.



The car next to mine in this picture is another M20 swapped 318is, but it's a slicktop and a completely stripped out track car. I also finally weighed my car. It weighed 2,864lbs with my tools, skateboards and camera gear in it, and that stuff weighs about 130lbs, so my car weighs 2,734lbs unloaded with a little more than a half tank of gas. Add 32lbs for the missing 5 gallons of gas for wet weight of 2,766lbs. I don't think that's half bad for a fully equipped Turbo E30.

Fun times. Some crap in the oil system (turbo feed is from an unfiltered oil gallery whether you use a sandwich plate or the pressure sender port) clogged the factory installed oil feed filter, so the turbo is trashed. Haven't taken it apart yet but I'm hoping the turbine side seal didn't wreck the center housing.




Luckily I didn't sell my spare 60 trim T3/T4 like I was planning to this summer, so I had a spare. Also, one of my front tires is showing cord on the inside edge, so it's time for new tire$$$. I probably won't be buying ZIIs or ZIIIs this time around, but a cheaper tire with a higher tread wear rating. It's not that my tires didn't last long, they lasted over two years and I put a lot of miles on this car, I just don't do autocross often enough to justify it and can't afford to do track days.

You could change your feed to here, it's straight out of the filter

That's fancy. Did you just drill/tap or is that something you bought? I'd do it but my oil cooler is in a box somewhere. Simply no place to put it with my massive IC and AC system, or nowhere with air flow anyway. Eventually I'll get some hoses made and put a cooler somewhere, but it's not a priority since the car is solely street driven.

I have a bunch of those factory oil adapter banjo bolts. I was going to drill/tap them for this very reason (and oil pressure senders).

I've downgraded to some mismatched all seasons on stock 14" wheels for the time being, this will get me through my upcoming trip and into winter break or early next year when I plan to get some new tires on my 16s.



I have no traction now. Especially on a wet road where I can't get into boost at all without spinning the tires until 3rd gear. Also, normal everyday cornering speeds with the star specs cause the rear end to feel loose with these.

You probably should. I'm going to try to figure out a way to use the stock oil cooler for this purpose, maybe I'll bypass the cooler, maybe hang it somewhere there is no airflow just so I can use the center bolt. Plan was to rig up a cooler for future track use that would either be behind the valance with a fan or external and removable for street driving.
