    You would also have to change the pedal and alter the ecu.

    Whats exactly done in the ecu i dont know but it will have to be altered

    What’s the setup You have. I assumed u were talking a car already running. If it’s a conversion it’s a lot easier

    OK simple.

    Easiest way it just use LS1 ecu and loom and modify that to suit the conversion. The LS1 loom and ecu can run any variat of the ls engines.

    Just make sure the ls2 and LS1 share the same reluctor wheel. Otherwise you will need to run a Linglefeter converter box.

    Then obviously a cable tb if the engine u buy has FBW.

    Only the late VZ LS1 was FBW. The rest were all Cable.

    Ls2 I’m unsure.

     

    if you haven’t picked an engine yet the l98 is the pick of the bunch. 6.0 and killer heads.

    You dont reckon an LS3 is better than a L98 Cav?  All forged internals etc?

    Oh of course its better. I didn’t factor that as most conversions are 5.7/6.0, however  the 6.2 is decent increase in $$$

    Yea for sure, always the way $$ increase, but the LS3 I was thinking should strat to come down as there are so many more of them out there now.
