I have just bought my first E30 a 318is. Runs well but I think it could be better. Its a little hesitant at starting and I think it could be a bit more responsive. Any quick fixes on these engines or tips on making them run better?
Also if anyone happens to have a good silver bonnet and drivers side wing going spare. I'd be interested.
Cheers
James

There are no quick tips. If it's new to you then I would suggest a full service:
-spark plugs
-HT leads if the current ones look old
-oil & filter
-coolant flush
-air filter
-gbox oil
-rear diff oil
The engine should pick up past 3.5K and revel in being revved.
It's amazing the difference basic servicing can make; I seem to be managing 3-4mpg more and gained around 8mph on top speed since changing the gbox/diff oil and fitting the correct wheels back on the car (less drag).

If none of the above helps (though it should), get a Viper2 chip for it; Ԛ£80 from ChippedUK.
You'll notice more power throughout the rev range, also you could try an E30Zone big-bore throttle body if you're really going to push it hard.

Fuel economy not much different - you'll want to drive it faster though, so... 
Chip reputed to give approx 150BHP, which seems about right, don't know about the TB, I didn't have mine long enough...

Well, I've got the standard factory chip and standard throttle body and mine doesn't hesistate.
Fix any problems before doing chip swaps or tuning.
I doubt that a chip will gain you 15BHP.
