Throttle body...
alright...what is the stock bore size of the GT and GTS throttle bodies???...I've talked to a company about throttle bodies and they make throttle bodies from 65mm to 105 mm ranging from 2 to 2.6 pounds...also, rather than get a new shet metal manifold made (too much money) I would use the existing plastic one or the sheet metal corolla one (and get it polished to a chrome finish), and port it...

its like this, they are single bore throttle bodies

65 mm throttle body, 3.125" OD
70 mm throttle body, 3.125" OD
75 mm throttle body, 3.125" OD
80 mm throttle body, 3.500" OD
90 mm Throttle body, 3.750" OD
95 mm throttle body, 4.250" OD
105 mm throttle body, 4.250" OD

the HUGE ones would definitely require a new Intake manifold, and probably a fabricated sandwich plate or spacer adapter

What are the specs on the stock throttle body, and what do you guys recommend...

they quoted me at just under $300 for the smaller ones (65mm to 80 mm)
