Welcome to LT1 Swap.COM Here you will find information on various LT1's, LS1's, and Vortec Truck engines I have installed or helped to install in many different vehicles. My goal is to provide as much information as I can for Do-It-Your Self-ers to successfully transplant LT1's, LS1's, Vortec or any other fuel injected GM engine. Please ask any questions you may have, I try to answer everyone's questions. Make sure you CLICK on the red links, I have a lot of info here and have split it into many different pages!!
PCM Reprogramming Services I will reprogram PCM's and burn custom chips to remove anti-theft, disable rear oxygen sensors and other emission related components, change fan on and off temps, injector size, engine displacement etc. $75 including return USPS shipping to do this. Vehicles include most all early 90s GMs, TPI, LT1 and all 1996-2007 Trucks, Camaro, Firebird, Corvette. I will get you're PCM sent back out within three business days after I receive it, usually quicker. Now supporting programming on 2007-09 Vortec Trucks E38 ECM for $150.00 with return shipping.
Wiring Harness Modification Information I have put together a bunch of information on various wiring harness as I come across them. Visit this section, I have information for most all LT1 harnesses, from Camaro, TransAm, Caprice, Roadmaster, Corvette and Pickup Trucks. I also have a very large amount of harness and general information for LS, LS1, LS3 Vortec Truck 4.8L, 5.3L, 6.0L, 6.2L 8.1L. Please do not skip this page, even if you are only looking for programming. Recent updates include 2007-2009 Vortec truck harness and 2010-11 L99, LS3 Camaro 6.2L,
Active Fuel Management Delete If you have a 2007+ New body style GM Pickup or SUV you may have the Active Fuel Management System on your engine, sometimes called DOD (Displacement on Demand) or AFM. This was on ALL 2007+ 5.3L engines, and some 6.0L and 6.2L in later years. The system was also on the 5.3L as early as 2005 in the Envoy, Trailblazer V8 models as well. I can disable this system to prevent oil consumption, and prevent future lifter failure. I have information on this page about mechanical repair if you've already had a failure. Click on the link for more info on this service. Programming starts at $50 depending on model, as always, all my programming includes the return shipping of your computer back to you.
Some of my interests and accomplishments...
Check out my Vortec 8100 Swap. I installed a 2001 Vortec 8100 (496 cubic inch) fuel injected Big Block Chevy with custom (DIY) closed loop fuel injection system and distributor-less ignition. I installed a ZZ502 cam. Two weeks later a piston fell apart and the 8100 sent a rod out the oil pan and is now out of the truck, here's some pictures of the destruction.
Here's the 2001 Vortec 6.0L (LQ4) truck engine I installed in spring of 2005, ended up selling it on Ebay. Megasquirt controlling fuel and spark, same as the 8100 above.
I have now come across a Vortec 5.3L and 4L60E I will be installing. !!!! Click Vortec 5.3L below. I test ran the engine on an engine stand using Ethanol made from a moonshine still. I used Megasquirt for fuel and ignition control.
Follow this link for more pics of the 383 LT1 and 305 TPI. LT1 was installed with a stock 1995 PCM and wiring harness I modified for the swap. The TPI is controlled by Megasquirt II using a MSD Pro Billet Distributor. All ignition and fuel control comes from Megasquirt II.
'62 Impala Page has a lot of info on my LT1 swap. This was my very first fuel injected swap. The LT1 and the car are now gone, but I've left all the information!! Included on this page is the VATS page, showing how to bypass GM's anti-theft system used in many early 90's vehicles.
My '67 Chevy Page has a little info about my pickup. I've done disc brake and 5 lug conversion. Other changes in store are drop spindles & springs.
Links includes other sites I found useful during my LT1 swap. added links 7/23/04
