Correct.

All this LS4/F40 stuff and much, much more is still in storage. The house we purchased has a 3 car garage, but with my wife's instance that she park in it, I won't be able to pull everything out of storage. I am currently working on the shelving and unpacking lots of stuff in the new garage in hopes to fit as much in it as possible.

In this "instance", your wife has made her insistence clear.

Patrick- now you are in trouble... Didn't you know that you are considered to be a sociopathic sadist on this forum if you help others with spelling or grammar?? Try pointing out that plural nouns do not use an apostrophe- Fieros, not Fiero's, and you will be crucified

If a member posts that he owns a 1983 Fiero with a stock 2.4L engine, it will get corrected within minutes by others. However, if the same person posts that he owns two 1983 Fiero's and that he loves his car's..... You will be booted from the forum if you try to help him improve his grammar or spelling skills.

Back on topic- I hope one day Guru can offer a kit for these motors... He does great work and this motor would be awesome. Maybe he can make enough money to kick the wife out of the garage and let her park in one of these http://www.costco.ca/12-ft....oduct.100229034.html

An LS engine is my dream engine, but I would need substantial help from someone to put one in. From what I understand they are no simple matter. I feel like I'm "settling" for a 3800SC when I would really prefer an LS4, or even an LS3.

If you want an auto, an LS4 is really no more difficult than a 3800 swap.

Well it looks like the biggest piece of this puzzle is about to find it's way to my door. Have located an LS4 engine and trans with wiring harness and ECM from a 2007 Impala SS. The wrecker will let me separate the trans from the package to save a little money and the pain of getting rid of it later, but I get to keep the starter. They did not keep the gas peddle with the package but after checking the part # they seem to be all the same for all engine options on the Impala from 2006 to 2011. So they can just grab one from another car in the yard and toss it in with the engine. I am not sure what the BCM looks like, or how much I need it. Does anyone know if it is the same on most of these cars also? Guru did you ever find any standard axles for the cobalt ss parts to hook up the fiero rear wheel hubs? Or are we still looking at cutting a couple of fiero axles to length then cutting new splines on them. Also any progress with this project in general? Would be good to have a simple version of the LS4 - F40 swap Just to get a car running, then upgrade it as time and budget allow.

I do finally have the two LS4 engines, 4T65e-hd and F40 transmissions in the new garage, but I am staying busy filling orders for current products and doing upgrades to my LS4/F40 fiero to get it ready for some more autocrossing this summer as well as long hauling the hotrod power tour.




I haven't done any additional work on the axle front. Probably the simplest way is to just get new shafts made that use the proper inboard and outboard joints.

I like this....
Thanks for doing this..
One thing I'd do off the bat is move the coil s (packs) off the valve covers.. just for looks.... grind down the stands and then paint the v/c red..

They do make covers to hide the coils under them (fake v/c's) but I'm thinking trapping the coil heat isn't a great idea

I know you listed under ground rules, to learn about the genIII ECU over the other type..
but the ECU type you used in your 1st swap.. how hard is it to program, tune, adjust as you add /change/update the set up?? and if it's not that hard to do, from the eyes of a newbie (not a person that can tune a g.m. ls tune in their sleep) .
What would the pro's and cons be of using the factory ecu over say.. the holley H/p ecu..

Always enjoyed seeing Paul's build take shape, may have to take a journey up that way just to take a gander.............

An LS4 with an auto might not be a bad thing...........

Especially if it already had Guru's tweaks.
