Not watched it as he's a muppet but if you fab everything yourself and don’t mind some bird shit welding, it'll be around 3 to 5k complete depending how lucky you are on finding parts! I'm about 3k in, not really keeping count on money as I just get bits from time to time. Easy done in a year but I've been slacking, also if you watch beytek, gav has the proper way of fitting a k20 in your bay by only ruining the subframe opposed to destroying your tunnel like most people do! At least you can replace a subframe easy enough if ever you decide to slap in a rotor motor again. Also just to add, I am a wanker, FACT!
