TurnKey install LS4 V8 engine to your Fiero

The GEN 4 LS4 engine. This engine was offered as a DoD ( displacement of demand ) AFM ( active fuel management )... Someone was thinking gas mileage, but the reports are that in the real world, you get about 2 more MPG out of DoD/AFM ... Is 2 MPG worth the long term possibilities of failure in this system? I am not a big fan of how DoD/AFM is implemented. The lifters are deactivated via turning off the oil flow to 4 selected lifters. When this oil is shut off, the lifter is rigid and the cylinder compression becomes a spring. See here for more details >>>>>> <<<<<<< ..

Now.... if you click on the above name, it will take you to a page that outlines many of the engine details.

What I am offering today, is a turnkey solution that will replace the 3800SC conversion. It takes time for the acceptance of a new powertrain to the Fiero. The 3800SC was being put into the Fiero in 1997, but it was not until 2002 that it really started to take hold as one of the most wanted installs today. Ease of installation, easy to get at salvage yards, and thousands of pictures posted across the internet gives lots of data about this install. For those people however that still need to have this turnkey service, I now offer a V8 solution. I have developed the AUTOMATIC install however. You might have found this website searching on other LSx type installations, and those you will see are 99% based on manual transmission installs. The only automatics I am aware of are the ones I have done. The same foundation as my success in 3800 installs applys here.... Lxx engines that meet my strict criteria for being less than 30k miles when I purchase them. Most all the Lxx GEN 3 engines I have today are less than 30k. My one LS4 I have is 3,658 miles.
