starter and wiring harness

if you want to mod it:
think about engine management, higer capacity injectors and aftermarket intercooler

and upgraded radiator

Does any one know the reason you need to swap tranys when doing the na/turbo swap? Wouldn’t they have the same sized housings anyway?

Different Gearing that better works with the tranny.

The n/a tranny won't hold up to the trq of the turbo engine.

you dont "need" to swap trannies but its the best option.

heres what you can do:
a) keep entire n/a drivetrain but just change the motor only. good if you are nice on the car and dont intend to modify it

b) swap whole drivetrain to turbo drivetrain

heres what you cant do:

use the turbo transmission with n/a rear, and vice versa
why: driveshaft is different size, you need a custom driveshaft
edit: dont quote me but i think you can use a slightly modified driveshaft from an automatic Fc

use n/a rear with turbo axles and vice versa
why: axels are totally different sizes

best option if you are on a tight budget is a)
best option overall is b) since you dont risk breaking anything
