 While the 24v conversion doesn't deliver much more raw power, it does make the E30 a lot more sprightly when it comes to accelerating. It is therefore crucial to make sure your brakes are up to scratch.

 If you really need to, you can lift the new engine straight out of the donor vehicle and into the recipient. However, if you have the time we strongly recommend you perform the following procedures on the engine prior to fitting:
-# Replace the sump gasket. These are a weak point on M20 engines and are a real pain to swap in situ.
+# Replace the manifold gasket. These are a weak point on M50 engines.
 # Remove the injectors and send them off for professional cleaning. This will give you significantly improved performance and economy. We recommend [http://www.e30zone.net/modules.php?name=Forums&file=viewtopic&t=152878 Injectortune].
 # Remove the [[Exhaust#Exhaust_Manifold|exhaust manifold]], replace the studs, then refit. Consider having the manifold skimmed for evenness. Be prepared to extract broken studs with a welded-on nut if necessary.
 # [[Changing_Belts|Replace the alternator belt]]. Might as well do it now.
 # Change the gearbox shifter seal. This little bugger is the cause of 99% of gearbox leaks. It takes 5 minutes and 2 pounds to do if the gearbox is off the car. It takes 5 hours if the gearbox has been fitted.
