Simple IS300 LS1 Swap I'm using this thread to document my progress on this project. Background: I'm more interested in performance driving than looking cool so I tend to mod my cars more towards function over fashion. Living on the island of Oahu in Hawaii, we don't have a track (shut down around 10 years ago) so autocross with the SCCA is my only performance driving outlet. My other car, a Honda S2000, was purchased due to my heavy interest in autocross. Due to the class I'm interested in and due to how good the car is out of the box, the major tuning I did is limited to suspension, bolt ons, and ecu flash. https://farm8.staticflickr.com/7207/...b9b64f61_c.jpg20140427_XE220654 by satoman44, on Flickr I was driving that car for almost 5 years when I started looking for a second car. My requirements were 4 doors, rear wheel drive, lightweight, and preferably with a v8. Unfortunately, there are no cars that seem to fit my requirements so I started at looking at LS swaps. I was looking at IS300's and G35 sedans as possible candidates. I settled on the IS300 due to the fact that it was smaller, lighter, and better built. They also feel much lighter when driving them. So after looking for 9 months, I finally found a 2004 auto sport design w/ LSD which I purchased in August 2015. It was in really bad shape so I got it for a nice price. https://farm2.staticflickr.com/1674/...9720f0b0_c.jpgUntitled by satoman44, on Flickr With any of my cars, my "stage 0" is always wheels/coilovers/audio/gauge cluster color change. So within a couple months, it looked like this. https://farm2.staticflickr.com/1557/...8b445468_c.jpg20160415__DSC4366 by satoman44, on Flickr The following posts will be documenting my LS swap adventure. You will notice I don't have the skills that most who do conversions have. I don't own or have the skills to fabricate parts. I rely on the swap parts available to me. That said, I'm still learning as I go and haven't even pulled a motor before this project! Current Swap Parts List: Swap kit from Dedicated Motorsports includes the following: -Engine Mounts -Trans Mount -Clutch Master -Clutch Line -Modified GTO front sump pan with pickup -1-3/4" Headers (driver side has steering column running between the runners) -Radiator Hoses -Wire Harness -Throttle Cable Bone stock 98 LS1 pulled from automatic Camaro T56 Magnum 4th Gen Fbody Bellhousing RPS Carbon Twin modified by Tony Mamo Monster LT1-S (need to sell after deciding to get the RPS) Fluidampr underdrive pulley |

Very nice. Well thought out and documented build. Motor mount pics ?? |
nice start to what will be a fun car... doing things like this in flip flops is very brave lol. |

nice work |
congrats and welcome to the LSX IS300 club. i just got mine running a couple weeks ago. just waiting for my buddy to have some time to finish my intake, exhaust and ABS delete. https://cimg5.ibsrv.net/gimg/ls1tech...303f6fb96a.jpg |

[/QUOTE] In Hawaii, it's common place to wear them all the time. You can tell I'm a noob lol. I'm just not used to wearing them since I'm usually just doing small mods to the car. You can see my friend in the pics who is actually wearing his work shoes since he's an auto tech.[/QUOTE] lol I get it ive walked into my garage before with them on.. it only took 1 time for something to happen before I wore shoes every time lol |
nah its cool the roadkill guys do it all the time! |
i didnt put a/c on it. only issue im having so far is trying to make the factory coolant temp gauge work. i dont have the factory ecu in anymore. besides that its pretty straight forward. mine is an auto though. |
Not much of an update, but I've been working on it every Saturday taking care of odds n ends and waiting on parts. Decided to do more trimming around the shifter https://c3.staticflickr.com/8/7171/2...e9d273d3_c.jpg20160521_IMG_2573 by satoman44, on Flickr Measuring up for driveshaft which needs to be shortened along with a new slip yoke and u-joint. https://c5.staticflickr.com/8/7475/2...c85eaf8d_c.jpg20160521_IMG_2576 by satoman44, on Flickr Steering column removed https://c3.staticflickr.com/8/7372/2...1b536ced_c.jpg20160521_IMG_2581 by satoman44, on Flickr Dedicated Motorsport IS300 swap headers test fit https://c5.staticflickr.com/8/7302/2...f9eb4e87_c.jpg20160521_IMG_2582 by satoman44, on Flickr The space between driver side runners which the steering shaft goes through https://c8.staticflickr.com/8/7101/2...06aae960_c.jpg20160521_IMG_2583 by satoman44, on Flickr Decided on this Tony Mamo modified RPS Billet Carbon Twin after realizing the Monster LT1-S was over 50 lbs. This RPS is 30.4 lbs, should make the engine feel almost as peppy as my S2000's F22 (hopefully). https://c8.staticflickr.com/8/7292/2...d68183ee_c.jpg20160527_IMG_2611 by satoman44, on Flickr Clutch cover removed https://c1.staticflickr.com/8/7107/2...13823a4b_c.jpg20160527_IMG_2613 by satoman44, on Flickr Detail https://c1.staticflickr.com/8/7665/2...ab560133_c.jpg20160527_IMG_2620 by satoman44, on Flickr More detail https://c4.staticflickr.com/8/7713/2...548f795c_c.jpg20160527_IMG_2622 by satoman44, on Flickr Flywheel with carbon friction inserts https://c5.staticflickr.com/8/7242/2...283cd688_c.jpg20160527_IMG_2635 by satoman44, on Flickr Pilot bearing installed.

Thus, this is where my progress has stopped for now. https://c8.staticflickr.com/8/7377/2...c1776cfd_c.jpg20160528_IMG_2646 by satoman44, on Flickr |
just curious as to why you pulled the steering column? also you might wanna pull the slip yoke out about 1/2 an inch and get the measurement for the driveshaft. gives some wiggle room for drivetrain movement. |

Is 1/2" the standard amount of slack to give the slip yoke? I just bottomed out for the measurement. I was planning to adjust for some slack in the slip yoke but not quite sure what to make it. |
ah ok. yeah i usually give half inch to an inch of play on the slip yoke. |
nice work! subscribed! Sandals in the garage are the best! |
Nice work. Did you use a cover alignment tool when you installed the front cover? That keeps the cover clearanced for the crank. |
