Aluminum 6 cylinder engines?


Recommended Posts

I was looking at alternatives to the popular iron block 6 cyl we have available to swap into the z, toyota sixes and nissan 6es (rb), but I don't really see a whole bunch of aluminum block sixes. is this for any particular reason?

 

The BMW aluminum 6 cylinder engines seem to have a bad rap, because of the nikasil coating on the cylinder walls instead of iron sleeves, but that seems to be the only problem.

 

Lets start a list a few aluminum 6 cyl engines you know of.

 

go!

What is the fascination with having an aluminum block? If it is weight, the 100 or so lbs you save from the block will be partially negated by the fact that an aluminum block engine will probably be DOHC which means the head will be taller, wider, heavier than a stock L28 head. Simply moving the 45# battery from the nose to the hatch area will probably give better F/R weight distribution.

 

If it is for WOW factor, then no questions asked. If it is for N/A power, will it make more power than a stroker? if it is turbo, then that's a whole nuther ballgame and weight savings from the engine block means nothing.

 

Dont dismiss the Chevy L6 as suggested. There is just something about a street car with boundless torque from a big 6.

I have wanted to do the Chevy 4.2 liter for a long time. Very few people have messed with them so far but I think that will change eventually. Here's a picture of the only guy that has given it a shot. This setup has been 8.62@174mph. I know it competed in the 03 or 04 Hot Rod Pump Gas Drags event.

I watched this "Ultimate Factories" show about a month ago and they were at the BMW engine factory. They were talking about how cool the aluminum block was for their I6 motor, and how hard it was to cast. A good 15-20 minutes of the show was about the block. I was surprised when they said that the block ended up weighing 90 lbs. An LS1 block weighs 92. I don't know how accurate the weight they quoted on the show was, but I know the 92 lbs for the LS is accurate.

 

The Chevy I6 was discussed briefly a couple years ago. I think the issue was that it was too tall. Here's the thread: http://forums.hybridz.org/showthread.php?t=87482 I'm not sure if they ever pinned down the height issue or not. I still remember that Baja truck. Thing sounded insane, like an old F1 car or something.
