MR2's are the only cars on which this setup seems to have anything resembling popularity.

it makes a lot of sense if you want a crazy HP monster but still want to drive the thing regularly. yes i know tom daily drives, but it has to be a pain in the butt iwht that peaky of a turbocharger

the only time a turbo should be "peaky" is when you choose something that is too small. a properly sized turbo will not be "peaky" because it won't create boost under cruising conditions

huh? i dont think ive ever heard a small turbo refered to as peaky? a large impeller in a large housing is going to take a larger load to spool up. it should then be able to flow more creating more power up in the revs. whereas a smaller turbo which can max its flow efficiency earlier on is going to provide a flatter curve up top, i.e. not peaky. go compare flow maps for different size slugs/wheels.. and then get back to installing your kit!

Exactly...a smaller turbo will be more responsive to the throttle and harder to control due to the quicker spool--that is how I interpret "peaky"
