Trying to see exactly how hard it would be to convert my 01 z06 to dbc so I can run a 4150-4500 throttle body? If there is any other way using my dbw I'm open ears, I have tried searching multiple forums but haven't had any solid info em pin out changing box delete etc thanks

The 01 should have a 411 ecu. It has the driver for IAC. You'll need to repin and have the ecu reprogrammed. LT1swap has info on this. Also note the change in the TCC disengage/CPP switch changes from DBW to cable.
Btw, Mast makes a DBW TB adapter to go on top of a carb manifold. Look at their "Old School" page.

See I was thinking about that just mounting my ls2 tb on top with a custom flange but wasn't sure on velocity etc when I asked mast about power velocity etc doing their setup he said he honestly doesn't know whatnot if there are any gains or losses . His exact words were " I do not know we have never dyno tested this on anything, it's mainly just for the old school look". To you know if I could just tube the tcc accordingly to make up for the changes needed. If you know or anyone else knows if there wouldn't be velocity issues I would be willing to try it

The single plane carb manifolds move a lot of air, just look at the power numbers for carb setups. As for losing bottom end, you should do as well as a carb setup, or better. Check over in the carb conversion board.

Ok I should just try the adaptor w/ low profile clamp on filter and see what happens then is what your saying ?

It's your money.... But if you're using an air filter on top, you'll need to eliminate the MAF, so you'll need an SD tune. But you would need that with a manual TB anyway on top of the repin and reprogram.

I know about having to go to SD not worried about that. Just if its not gonna be worth trying an adaptor, then ill just try and find more info and do the dbc swap. Thanks

I guess what I am asking is should I do a. Aaron's high flow 90* b. run tb on top if manifold with a adaptor or c. Do dbc conversion
