What engine is for me?
So you decided your going to make your e30 a beast by putting in a monster four-valve BMW V8 engine. However, there are somethings you should know before picking your engine. The M60 is a very poplar choice due to the fact that is cheap, came in many cars, and whole cars can be bought for $1000. M60s can be found be in E32 and E34 series. (93-97) There is a 4 liter and a 3 liter version. 4 liters in the 540i 740i and 840i. The 3-liter version was installed in the 530i and 730i.

In 1997 the m60 was replaced with the M62. All these motors came with alusil blocks so this is a huge plus. The engine capacity was increased to either 3.5 (from 3.0) or 4.4 (from 4.0) liter. Early engines were non-vanos (makes swap easier). Later in their life, however; vanos was added as well as an EWS system (antitheft). If you have a later engine with vanos and the EWS, a couple factors are added to your swap. Some have been able to remove EWS using a chip or some other mods. Another route is to make sure that you get a complete ews system with the motor as well as the specific key to the system as well. Thats the ews box, keys (with chips in them), receiver, and ring. The ews system can be incorporated into the wiring, however; it gets complicated very quickly. More info coming soon!
M62 block with M60 goodies
This route is one we took on our very own Lela. You start with an m62 engine (which are all alusil, so you wont have to worry about getting a bad block), you take the complete wiring, sensors and dme from an m60 4.0 (which can all be taken from a junkyard for fairly cheap). You then modify the cam hall effect sensor to only have one tooth like the m60 sensor. Then comes the hard part, you either use the m60 front chain cover, or cut the mount for the trigger off the m60 cover and weld it onto your m62 cover. WARNING! This requires a skilled welder since its cast. Many cast item require both a post heat and a preheat! This setup requires additional work and a proper tune (which we can do), however you do get the best of all worlds. Simplified wiring, an extra .4 liters, a chance to grab and bolt on the m60 intake, and make extra power with a proper tune since those manifolds flow better. Its a win/win. Click here
