i have a few questions for the people in the know!

if i miss an important question to ask please reply with an answer, thankyou

car info:1994 celica gt with 5SFE, automatic, FWD



1.Power per dollar wich gen of the 3SGTE would be best? (i was thinking st215/st205)

2.if the engine is made for AWD how will my FWD handle that extra power?, is a conversion absolutly necesery?

3.I dont want to change it to a manual (if possible) will this result in power loss? if yes how much?, is there an automatic alternative? (Auto Gearbox from GT4?)

4.trouble spots to be wary of?, anything in particular

5.Reasonable price? ive found a 3SGTE with no gearbox for $4000 AUSD (australian dollars) good price?
