hello everyone got a question. I have found a ls1 engine out of a 98 transam with the 6 speed trani. what kind of mods will i have to do to make it fit in my car I have a 2000 firebird. My primary concern is the wire harness. I've heard the molex connector on the ls1 might not match up to my car does anyone know? Any info would be helpful

the curb that you don\'t see is always the most damaging -

Yup, I did.
Swapping a 98 LS1 into a 98 car is semi-easy as is a 99-02 LS1 into a 99-02 car. The only reason I say this is due to the fueling changes between the 98/99 year (EVAP and fuel level sender). You will still need to modify the PCM to underhood harness. The LS1 uses a power wire for each bank (IGN/INJ) where as the V6 uses just one for all. Pin B on the gray LS1 connection isn't present on the V6 plug. You will have to pull it and splice it with another power wire. You can use my wiring diagram as reference for which wire you should share power with. If you remove a lot of your accessories, I recommend using that wire. If you do not do this, only half of your engine will run.Keith - Chicago<br /><a href=\"http://www.hptuners.com\" target=\"_blank\">HP Tuners - PCM Reprogramming</a><br /><a href=\"http://www.dxsoftware.com/magnus/\" target=\"_blank\">97 Firebird V6 to LS1 swap</a><br /><b>V8 9.967@132.78</b> 1.322 60\' NA Heads/Cam<br /><b>V8 10.295@128.48</b> 1.363 60\' NA Cam Only<br /><b>V8 10.987@119.31</b> 1.422 60\' NA Stock Internals<br /><b>V6 13.674@98.22</b> NA<br /><b>V6 12.394@104.91</b> N20 100HPComment
