Well...When You Swap A FWD Engine On RWD Car...You Need To Care About Somethings 1st Before Going And Making Sure If They Are Possible....!!
1st Thing You Need Is To Mate A Suitable RWD Gearbox To It....A FWD Gearbox Is No Use Now In RWD...You Need A RWD Gearbox In Order To Drive The Propeller Shaft And So Differential...!!
FlyWheel Clutch And Pressure Plate...make Sure The Gearbox You are Mating Fits The Clutch And Pressure Plate Along With Matched FlyWheel For Engine...!!
Later Matching The Propeller Length With Gearbox Till Differential....!!And Making Mounts
In TOYOTA If You Need 2.4L ...Go For 1JZ-GE As It Came In RWD And Have Some Serious Power
Less Than That A 4AGE Can Also Fit Mating With T-50 Tranny.....Not T-20...Correcting here...!! Its 1.6L Performance Engine With Nice Decent Power...!
