I don't know about spending $18k-$20 just yet haha
The place where i'm going to go get it engineered said if they were to do all the work for some one on just the engine conversion (which is all i plan on doing for now) would be about $5k-$10, so now if that with that price it mine it should roughly be around $5k i thinking for me, but i have no doubt that over the years to come and upgrades i'll be doing i will spend something like $18k-$20k
