h4nsm0l3m4n Posted November 8, 2010 Share Posted November 8, 2010 (edited) Hey guys, I've been working on swapping an LS1 into my Z for a few months now and I figured I'd post something up sooner or later before I was done. Yesterday it finally struck me that... theres not much left to do, so I just wanted to share my progess Here are some pics (you can find more if you click in my sig), a brief descriptions follows: Before I installed the LS1 I decided to sandblast, fix all the rust and paint the engine bay. I painted it "Championship White" from the Acura Inegra Type R, which is the color I plan for the rest of the car. I think it turned out great (for my fist attempt at painting ever) now I just wished I had painted it all at once! I also put in toyota 4x4 calipers and ran all installed all new brake lines for the car. The engine swap itself is nothing crazy, just a stock LS1/T56 from a 2000 firebird (77k miles),no turbos or anything. Since this car will see a lot of track time and I've read the F-body stock pan baffling is relatively poor I dropped the oilpan and put in a new baffle from Improved Racing. For fuel I'm using a Walbro 255 lph pump, corvette FPR, new 3/8" hard lines and the stock 260z tank. I'm also running a surge tank from BC Broncos fed by a second, low pressure pump. To clean up the fuel lines in the engine bay I flipped the LS1 fuel rail. For wiring I got a standalone harness and flashed ecu from chevythunder.com and am in the process of finishing up the wiring inside the car. Chevythunder provided me with appropriate fan relays and fuses for the Ford Taurus fan I'll be running Whats left? Not much! For wiring I need to hook up the standalone harness to the ignition and run wires for the Walbro pump. For mechanical parts, I'm going to design and order sheet metal mounts for my Taurus fan. I also need to hard mount the new ecu, relays and fuse box. Lastly I'm waiting on driveshaft from JCI and its off to the exhaust shop to weld up exhaust and fire the beast up!

drvrswntd Posted November 13, 2010 Share Posted November 13, 2010 You have PM about fueling system, thanks! Quote Link to comment Share on other sites More sharing options...
h4nsm0l3m4n Posted November 18, 2010 Author Share Posted November 18, 2010 Just got home from the shop and thought I'd throw up a quick update. During the last few days I finally wired up the standalone harness to the stock wiring and ran wires of the new high pressure pump. Yesterday was spent sorting through the fuel system and fixing a few leaks that cropped up. Today I filled the car with oil and water (appropriately). With not much left to do I sat down, put the key in the ignition, turned to "start".... and was rewarded with a blast of angry V8 music through open headers! I was so amazed.. It barely cranks over before it roars to life like its a brand new car! Tomorrow I'm calling up the exhaust shop and scheduling an appointment for early next week. In the mean time I still have a few things to do mainly, mount the electric fan on the radiator, mount the ECU, relays, and fuse box, and wire up the Autometer tach, and speedo. I also need to insulate all the wires from the headers and do some general fit and finish type stuff to get the car driveable. Its getting close! drvrswntd: never got a PM from you, just FYI Quote Link to comment Share on other sites More sharing options...

h4nsm0l3m4n Posted January 7, 2011 Author Share Posted January 7, 2011 I thought I'd post a quick wrap up of the swap now that its all done and running. Exhaust work was completed the week of Thanksgiving. I have 2.5" pipes running into a 2.5"-3" y pipe, 3" glasspack and a magnaflow muffler. It sounds great, has a nice rumble but no harshness or drone. After that it took about a week to get everything else sorted out. Heres some pics of if "finished" I've been driving it every day since, already put about 1000 miles on it. Runs great, good gas mileage (20+ combined at least), and is very reliable. I gave myself a little present for the holidays and took it to Portland Speed Industries for a little dyno tuning. Got some nice results(blue is was the before tune, red is the current tune): And a video: http://vimeo.com/18403958 All thats left now is to do everything else Quote Link to comment Share on other sites More sharing options...
sq_creations Posted January 7, 2011 Share Posted January 7, 2011 It picked up some pretty nice mid range power. Very nice! Quote Link to comment Share on other sites More sharing options...
