jimmyfloyd Posted May 26, 2010 Report Share Posted May 26, 2010 Saw this on CL and wondered what people knew about it or thought about it? http://newlondon.craigslist.org/cto/1716115473.html This posting is about a motor, which just happens to be bolted into a fiero. The motor is something that you have probably never seen before or even heard of. Its an alumninum 2.8L v6. this means the block is aluminum, the CYLINDER BORES are aluminum and the heads (Gen 1 60*) are aluminum (small valves, not the fiero 2.8 HO valves). This motor Runs and can be started for you. It was my DD until the clutch went on the car. This is the only Complete and running version of this motor in the world*. I know of one other block and set of heads, dont know where the heads are, but can get info on the block. This was part of an engine development program for the turbocharged fieros in the mid 80's and I have all the proof you need. the block weighs 38lbs bare. * Gm may have one in the turbo fiero they bring out every 10 years, but can not confirm the motor was not swapped to a iron block/head combo.

xtremerevolution Posted May 26, 2010 Report Share Posted May 26, 2010 Aluminum cylinder bores and forged pistons? Can you say oil burner? Quote Link to comment Share on other sites More sharing options...
slick Posted May 26, 2010 Report Share Posted May 26, 2010 They pop up on ebay and CL every once in a while. Probably worth picking up if you want to build a nice hybrid. Quote Link to comment Share on other sites More sharing options...
tornado_735 Posted May 26, 2010 Report Share Posted May 26, 2010 I didn't think aluminum would stand up to combustion temperatures. That's why Land Rovers are always dropping cylinder sleeves. Quote Link to comment Share on other sites More sharing options...

I wonder how the LS based engines work then... Quote Link to comment Share on other sites More sharing options...
tornado_735 Posted May 26, 2010 Report Share Posted May 26, 2010 Hmm... I wonder how the LS based engines work then... I would assume the cylinders have iron liners in them? :shrug:I assumed all aluminum block engines had sleeves in them. Maybe I'm wrong.

RobertISaar Posted May 26, 2010 Report Share Posted May 26, 2010 it's still a Gen1 block... which means it doesn't have the priority main main oiling or the roller lifters that the Gen3 660s got... that alone is reason enough for me to pass it over.

GP1138 Posted May 27, 2010 Report Share Posted May 27, 2010 I think N* engines have aluminum blocks as well... Quote Link to comment Share on other sites More sharing options...

xtremerevolution Posted May 27, 2010 Report Share Posted May 27, 2010 Yes, but IIRC they have iron cylinder liners, just as the Jaguar V12's do. This guy claims that the cylinder bores are aluminum. Sounds like a pretty bad way to go. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted May 27, 2010 Report Share Posted May 27, 2010 (edited) Yes, but IIRC they have iron cylinder liners, just as the Jaguar V12's do. This guy claims that the cylinder bores are aluminum. Sounds like a pretty bad way to go. they sell them through summit as well IIRC... it might list liner material. EDIT: http://www.s-series.org/htm/tech/GMPerfParts/144-148.pdf "This heavy-duty aluminum block is 47 pounds lighter than a production rear- wheel-drive cast iron block. It has extra-thick cylinder walls with dry nodular iron sleeves." Edited May 27, 2010 by RobertISaar Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted May 27, 2010 Report Share Posted May 27, 2010 He's wrong about the liner, I don't think GM has built an aluminum block engine without iron liners since the Chevy Vega. Quote Link to comment Share on other sites More sharing options...
Galaxie500XL Posted May 27, 2010 Report Share Posted May 27, 2010 The Vega was exactly what I was thinking of. GM had convinced themselves in that case that an iron sleeve was unnecessary, due to the high silicon content of the aluminum. Didn't take long to find out just how wrong they were... Personally, I can think of much better ways to save 47 pounds. Quote Link to comment Share on other sites More sharing options...
