Default Dropping a motor inches?

I have never heard of this. But a guy at the track said I should get a H22 and drop the motor 2 inches for performance? I have never heard of this and seems it would be a pain in the ass to do. Could you benifit from this? or is this guy just a dumbass?

the only benefit i could see from it is a lower center of gravity which would help in turning. but i :dunno:

I'd say the guy's a dumbass. You could probably do it, but the shift linkage cable's might no reach, you'd probably screw up the driveline angles on the axle's and the next big rock you hit on the highway is probably going to rip your oil pan in half.

There is a benefit to mounting an engine as low as possible in a chassis, lower center of gravity and all that. It's really not something you can just do with a street car though.

I have heard this theory before and the idea is that the straighter the driveline the more power you can yield from it.

Never heard anyone actually doing this on a street level but they use this for touring racing because it lowers the cars center of gravity.

I've seen it done alot for v6's and v8's in 240sx's. I think its a center of gravity issue as much as it is a fitment issue. They also push the engine back in the engine bay to improve the longitudinal[sp?] center of gravity.

Keep in mind, although these are street driven, they are on a VERY large budget, so its pretty much out of the question for most enthusiasts.

i like johns point about the drive shafts. lowering the motor would decrease the angle put on the cv joints thereby gaining lost friction energy....though that would mean your axles would have to be somehow shortened....

You can actually get the custom built axles for this from several manufacturers or you can mix and match your axle setup to get deired results...... suggest buying the custom ones though.

its possible but the h22 engine is already really low in the engine bay, and if its daily driven i would really recommend against it unless u want to go thru oil pans quickly and jack up ur ride, it would require a special mounting kit and the concept doesnt seem very good to me because ur be lengthening ur motor mounts making them weaker structurally....

I would wager a guess that it's generally a bit easier to accomplish this with a rwd that doesn't use a transaxle since the only "geometry" change is how the driveshaft lies under the car. The way most fwd cars are packaged it would require changing up a lot more stuff.

Not worth the hassle.

Besides, can you say "jacked up header and oil pan"?
