Episode 4 has a 4g63t 1992 colt.
The show doesn't show much for what is done to the engines.
Is this guy on the forums?

I spent an hour or so on google trying to find info on what injectors or turbo or power he was making to no avail a couple weeks ago. AWD swap and good rally tires would have been nice. Wish he would have asked for donations during his 7 days of prep before the race.

Yes I agree AWD was what you need against an AWD lambourgini. And rally tires.
His colt is probably a great little street car, but was not setup for who he was against at the end.
I really didn't think the show was very well thought out.
The guy that won didn't even own his car???
