    So I know it's been done to the 350 but anybody with twins on a 300. I am looking to do something diffrent with my 300 fabrication won't be an issue but picking the right turbos is. I want something that will spool quickly. I am only gonna be turning this motor to 47-4800 so I think I can get away with a small pair of turbos. I already have the manifolds all they will need is an adapter flange. I was was thinking two T04e turbo like the Burton kits but I am not sure which ar to use. Of course I will probably use some sort of fuel injection to aid in tuning. This is a far off project but I am starting to get stuff when I trip over a good deal. Also are there any stock turbos that may work? I figure two off of a 2.0 to 2.5 liter 4cylinder should get the job done. I am not looking for crazy power maybe 350 to 375 crank horse power. I think this would be an easily attained number on low boost and a freshened stock motor. As always thanks for the info guys

    Two stock GN Turbos would be perfect, and cheap

    Before I read the link above, I would have said a t3, then a t4 flange.

    A/R would be .5 or .63 for faster low-flow velocity spoolup.

    GN turbo's use a Buick specific 3 bolt flange. (and are getting harder to find, Cotton is buying cores for $100)

    Anyway, the link suggests different thoughts.

    You are going to have a unique build!

    Two Mitsubishi Eclipse Turbos would work well , too , CXracing has some for cheap but they are cheap for a reason...

    Thanks for the replyguys.I have a 430 for the car also but I really dig this little 300. It's light sounds awesome and really runs good for what it is. Thanks for the article links also I think I bought that one because I was researching this stuff.I have had this car 19 years me and my dad restored it for my first ride. I just got it out after a 7 year hibernation due to a 2004r swap not going so well. I have been driving it everyday rain or shine since just before memorial day. Like a said I doubt this will happen soon.I am a planning type of guy though so I like to have direction. Plus this way I can't weight on the deals. I may do a blow through carb first due to money we will see. I don't want crazy power just something that's a fun street car. T04 were what I was looking at just deciding on trim and are sizes I am thinking 57 trim ? With something in the low .6??? Ar to get it to virtually no lag. By the way this is a 67 gs340 car I tried posting a pic but it says it's to large.

    Once you have the pictures onto photobucket you:

    click on the photo you want to post.

    click on the IMG code and copy it. It should look like this:

    [UR=http://smg.photobucket.com/user/seanbuick76/media/2000%20E-450%20cube%20van/DSC04137_zpskqb81lcw.jpg.html]http://img.photobucket.com/albums/v732/seanbuick76/2000%20E-450%20cube%20van/DSC04137_zpskqb81lcw.jpg[/IM][/URL]

    And then paste it onto your threads on here and it will show up a full sized photo
