I have a MY98 UK turbo Wagon version 4. My engine is on the way out as its have 63k on it already plus i am doing loads of track days.

So i am planning to get a Sti engine for spare in case anything happen after Spa and the Ring in august.

What do i need if i want to put a Sti engine into my Wagaon? Is it just ECU and loom?

Thanks

DIxon
