Why would a 4cyl mustang be a bad idea?

[OnMy3rdStang]

I own an 89 4 cylinder mustang and I only pay 90 bucks a month for insurance.

Stereotypically a mustang is a 5.0 and there are alot of people who dont concider a 4 cylinder a real mustang, but there are alot of potential and room for change like a turbo 4, v6, and v-8 swaps and the best thing about swapping engines is sometimes you can get away with 4 cylinder insurance and still have a v-8 since the cars vin has the 4 cylinder code in it.

So yeah you wont have the power of a v-8 (obviously) but just because its a 4 cylinder doesnt mean it has to stay one
