The main reason is...I can build it to run Natty. I'm tired of the D16Y8 and want to have a stronger motor in there. I can then sit on the the F22 running n/a and wait for the money to boost it later. Once the hard part, the swap is out of the way, I'll have a competitive car and then with the boost I'll have a REALLY competitive car. Keep in mind money comes, but money comes slowly for me. So it's a bit of a reward to myself to get the motor built strong, swap it, then boost it later. At least while waiting for the boost upgrade I'll have something to enjoy in the meantime.
