TD05s are kinda small, so they spool pretty quick actually. for my car, they're actually not all that desireable. they are internally gated, but i've seen a few people that removed the flap and widened the port to add an external. my car (stock) runs out of power around 5800 or so. i blame the shit stock cam (not made for higher revving) and the 7:1 compression. for a Honda app, i've heard they're pretty good. plus you could find em all over ebay. and plus you can find most of them with the original manifold, so getting a flange isn't that hard either.
