get the wiring diagrams for BOTH cars...that's a good start.
What is the engine code number?
Then figure out the fuel injection
Then figure out mounting
Then figure out cooling.
Fgure out the inter-cooler ducting
Then figure out exhaust.
Then figure out the suspension
Then the brakes for twice the horsepower
Do you have the skills for this big job?
A 1.8 swap is not especially difficult but there are pit-falls for the noobie. A 1.8 TURBO is a very big job
