This list isn't complete, I'm sure there are a few adapters and hoses here and there that I'm neglecting. but the eventual goal is to cover EVERYTHING you need to get the job done. If you know of things I missed, or even have links to good threads that offer more detail on a particular topic reply to this thread or PM me with the info and I'll add it Smile
Engine and Transmission Options:The Engine is what you really came here for right? The LS engines are all very similar in terms of their construction and how they fit in the car. Any of these options should be treated the same way when swapped into the car.
Engine OptionsLS Engine Specs-LS1, Found in: 97-04 Corvette, 98-02 Camaro, Firebird, Corvette C5, 04 GTO-LS2, Found in: 06-07 CTS-V, 05-07 Corvette, 05-06 SSR, 05-06 GTO-LS3, Found in: 08+ Corvette-LS6, Found in: 04-05 CTS-V, Corvette C5 Z06-LS7, Found in: 06-08 Corvette Z06
*Engines from the F-Body Cars (Camaro and Firebird) use a normal throttle while other cars on this list use drive by wire. Each has it's advantages so do your research, if you go DBW make sure your engine set includes the electronic gas pedal, the throttle actuator control module, and the small harness that connects the pedal to the module. The throttle body TAC module and pedal need to all be from the same year and model as there are differences between these and other GM vehicles with DBW.
When buying an engine it should include the following-Alternator-A/C Compressor (if you plan on hooking up AC)-MAF (mass airflow sensor)-Power Steering Pump-Complete uncut Wiring Harness-PCM (engine control module aka ECU)-Throttlebody-***Transmission. Not required but you're life will be easier if the transmission is already installed
In general you'll want a motor that will not need anything extra to get it running.
Transmission options-T5*, Found in: 97-02 Camaro, Firebird-T56*, Found in: 97-02 Camaro, Firebird-4L60E*, Found in: 97-02 Camaro, Firebird
When buying a transmission separate from the motor should include the following:-pilot bearing-Bellhousing-T56 torque arm mount and bolts-Shifter Assembly-** Pressure plate/Clutch (and all related bolts and clutch tool)-** Flywheel (only necessary of the motor was original mated to an automatic transmission)
If anything on these lists is missing you will need to buy them separate
*These transmissions can be found in other cars and model years as well however they differ in their setup depending on the application they were original intended for, you should seek transmissions designed to be paired to an LS motor and used in a Camaro or Firebird Chassis (even the GTO, Corvette and other GM applications are different). You can make the other version work but be sure to DO YOUR RESEARCH to determine the differences so you know what you're getting into.
**If the Transmission was purchased separate chances are you will have to buy a clutch and pressure plate before you can mate the two. The best cheap setup is to get a Z06 Clutch setup... you can get a new Exedy clutch pressure plate, and flywheel designed as a direct OEM Z06 replacement for around $350.
Mounting Options:Mounting an LS motor in your S-chassis is fairly straight forward, the engine bay is quite accommodating. In generally you're looking at engine mounts as well as a transmission mount and a transmission cross member.
The biggest problem is how the engine's oil pan fits around the 240sx's front sub fram (aka engine crossmember). You can either modify the sub frame to accommodate the oil pan or modify the oil pan to accommodate the sub frame.
In general you will not need to modify the firewall or transmission tunnel to fit the LS engine unless you are using a custom setup. Worst Case scenario is a minor amount of hammering at the front of the transmission tunnel with certain kits.

Completely Custom-Use of GTO oil pan recommended or build custom-Expect to modify cross member or oil pan for proper fitment-Use of Corvette Engine mounts with spacers or built custom-Built custom Transmission cross member and mount-Order Custom Driveshaft from a Drive shaft shop (do not order from kit makers, it may be wrong length for your application)*-May require transmission tunnel hammering or cutting depending on placement
*Keep in mind that the factory vLSD requires a driveshaft that is .75" shorter than a Factory Open-Diff. Also if using alternative drop-in options such as a Kaaz or J30 diff the required drive shaft size may be different. I've heard that the size difference is typically inconsequential however if you're ordering a custom shaft anyway, it's something to keep in mind.
Automatic to Manual ConversionIf you're converting your Automatic S-Chassis to a Stick shift at the same time you do your engine swap you will need the following parts-240sx Brake pedal assembly (from 5-speed car)**-240sx clutch pedal assembly*-240sx Shifter Trim (plastic interior surround-240sx Shifter Boot (leather or vinyl to mate shifter to trim)-240sx transmission boot/rubber seal (seals the interior from the exterior)
Your best bet is to find these in a junk yard, on ebay or a forum BST. Failing that these parts can be purchased new from:
http://heavythrottle.comhttp://courtesyparts.com
*S13 clutch pedal can be used on an S14 but it needs spacers on the mounting bolts to sit properly, s14 clutch pedal cannot be used on S13 because the spacers are welded in place from the factory.
**if you can't find a brake pedal assembly or maybe you just want to save some cash, you can take a hack-saw and cut off part of the pedal to make room for the clutch. cutting it and placing a factory rubber pedal cover from a 5-speed it will look and feel like a 5-speed pedal.
Clutch Parts:you will need to replace the clutch master on your 240 with something stronger and you need to make sure it works with the T-5 or T-56 transmission.
