    replacing dead ls1 - quote feedback request

    hey guys, I've posted recently about my 98 Trans am running dry of oil, the engine has 143k miles and the engine is dead basically, the car is almost perfect condition as far interior and exterior appearance, I just received a quotation with 2 options - 1st is LS6 replacement swap - pretty straightforward 2nd option is custom rebuild of existing Ls1 - I am hoping you guys can give me some feedback and/or what questions I should ask the shop that im looking to do the work for me. I work for the phone company and am incapable of doing this myself.
    any feedback or input is appreciated so that I can ensure nothing is being missed in the quote or if theres anything you would recommend differently etc - my budget is 7k-9k

    Most importantly, thank you for the feedback.

    Can you please elaborate on the new wiring requirement?

    It's my understanding that my LS1 ECU/Computer was compatible with and LS6, however a dyno tune would be required to wake up the Ponies.

    LS6 is a drop in motor... no new mods really required... you'll only need to reuse your oil pan from your LS1...

    the LS3 will be more work... i believe GM high tech perfomance had an article where they dropped in a LS3... i forget what month it was...

    Here are my issues with this quote with my suggestions in BOLD

    They should be using an experienced tuner with HpTuners or EFILive to correct the computer calibration for the engine/trans mods. If they are using a handheld, the results probablly won't be that great, if it works at all.

    OTHER PARTS
    K&N INTAKE - $303.95
    Thats a lot for an intake setup. You could save some money here just getting a lid

    LS6 INTAKE POLISHED - $585
    hmmm....I'd skip this too. I've never heard of someone polishing a plastic intake. The LS6 intake is fine just the way it is and doesn't really need anything

    3600 STALL CONVERTER - 242931 $499.95
    That part number comes up a TCI converter. You'd be better off spending some extra dollars here and getting a nice converter like Yank. Do a search on torque converters to find the best brands for LS1s

    make sure you understand what you are getting here. These are performance bushings and will ride stiffer and might be squeaky/creaky. They will perform much better than the stock ones, but I wanted to make sure you know what you are getting here.

    I agree with Cutlass. Skip there tune and get a mail order from Frost. Skip the k&n and go with a lid with k&n filter. Skip the "polished" ls6 intake and get a Shaner ported TB. For the poly bushings, be sure they order black ones. I read from Prothane (i believe) that the black busings contain some natural grease that cuts down alot on squeaks. You can save yourself around $500 by going with what Cutlass said. There's the extra scratch to get yourself a nice triple disc 3600 stall converter.
