I wrote a similar thread a while back...
I swapped a full V7 EJ207 into my bugeye RS.
After 25,000km and a year and a half.... I conditionally love it.
When its running well and I can get in and go... oh hell yes. I know there are faster cars, nicer cars... but this car really is mine
. I know every bolt, every bushing, every component of the car and there is simply no substitute for that.
However, when its not working.. or when im trying to fix something... and I cant just get in and drive it...I hate it. I dream about selling it and buying an Audi.
Currently (as of Sunday), the car is working... so I love it.
Do I regret doing it? Absolutely not. I had the money and time to sink into the project and treated it as a learning experience. I definitely didn't research enough and I definitely didn't have the parts on hand that I needed... but I learned a lot.
