LS4 / F40 swap - fieroguru (Page 47/216) fieroguru JUN 04, 08:05 PM Spent most of the evening putting the black car back into rolling state with the LS4/F40 in the engine bay so I can dolly it to the new house. It will be early to mid July before I get my new garage in order to the point of finishing this swap. I still need to pack the interior with all the boxes of parts for this swap. iluvsd619 JUL 01, 10:42 PM Had to Bump for you. Just waiting. fieroguru JUL 24, 08:01 PM Finally got the new garage to the point I could fit the LS4/F40 coupe in it... now I just need to get focused on actually working on it again! dobey JUL 27, 09:13 AM Nice! Looking forward to seeing more updates and seeing how your flywheel/clutch works out. fieroguru AUG 26, 08:10 PM Owing a house again after 6.5 years renting is a good and bad thing... Good in that I will eventually be able to build a larger garage (had 4500+ sq ft of garage space in IL), bad in that my wife for the first time in 6.5 years can request changes/updates to the house. So I have been very busy with house stuff (alarming all windows, installing an 8 camera security system, cell phone booster, outdoor temp gizmo, no soliciting sign, power washing the exterior and the deck... it truly is an endless list that she adds to on a daily basis (this week it is porch swing and kids swingset/play house). We also sold the commercial building back in IL last week which makes us very, very happy and should help enable a garage expansion in the next year or two. I was able to get caught up on my current honey do list and worked on getting the LS4/F40 back out of the chassis so I can start working on it some more. Today I ordered a bunch of needed parts: backup light pigtail, 100 ECM pins, AN fittings and PTFE braided hose for the fuel lines, replacement AC compressor hose, and rubber isolation mounts for the ecm. I think this is the place the ecm will be mounted. I just need to make a couple of brackets for it off the start mount and the front transmission mount. Trinten AUG 26, 10:43 PM Garage is looking great, so is that engine! Congrats on the sale! dobey AUG 27, 10:09 AM Don't know if you've thought about it much at all, but I noticed that my Avalanche has a bracket which mounts the ECM in a vertical position, and thought it might be possible to use it in a Fiero. I haven't looked into how it mounts up into detail yet though. http://www.tonkinonlinepart...104047/15905990.html fieroguru AUG 28, 07:53 PM quote Originally posted by dobey: Don't know if you've thought about it much at all, but I noticed that my Avalanche has a bracket which mounts the ECM in a vertical position, and thought it might be possible to use it in a Fiero.

The 4 feet were $12 shipped. Sorry for the crappy ebay pic. fieroguru AUG 28, 07:59 PM I am going to try and get something completed on the swap every couple of days so progress will continue. Tonight I welded in the two O2 sensor bungs. One for the ECM and the other for the wideband: Then drilled the muffler support bracket to accept the harness side O2 connector: I needed to get the o2 sensor located so I can start building the harness which starts with the camshaft sensor and the O2 sensor.
