Try the k20a2 swap into a 7th gen civ in 2002. We had to make up everything. Buying parts here, buying parts there. Returning parts. Wiring problems. Took 4 months to get it done properly and thats with HASPORT was working with us. We helped each other for 4 months until it finally got done. That swap sucked!
I ended up driving a 72 bug for those 4 months. NOW THAT REALLY SUCKED !!!! SORRY BUG FANS!!!
