12 or 13,000 what?
anyways. being a manual is obviously going to hurt you. going with low rear end gears like 3.23's should help load the car and spool the turbo faster but a 88mm on a 400+ci motor will not be bad at all there are mustang guys running 4788's on 347's and a local guy is running twin 4788's a a 40x ci sbf

i wouldnt go any smaller than an 88 on a 403. call or email forced inductions. they will be able to help you out with turbo sizing for your needs.

the intake is 80mm not the outside of the wheel its a stret driven car so i was thinking a gt45 would be better what sort of rpm diffrence would there between a gt47 and 45 spooling up

A 403 and a GT47 is good on the intake side. The turbine side is a touch small. I would go with the new GT5018. Same turbo, just has the new 98mm turbine wheel from Garrett.
