found an s4 biturbo engine with 34,000mi. but the car was recked from the rear. it was a 2.7lbi and it was going for $3,000. my mechanic said he would do the swap for 2,500-3000 depending on wat i need. so i would rather get the swap done and get the same amount of power than having 94,000mi. with a pes supercharger. but the thing is if i got a swap i would want to also convert the tranny to a 6spd so u r rite i should just look for an s4. if u no any s4's for sale anywhere from 12000-15,000 please let me no!
