this doing things in stages is why my tiny cvh runs a t34 so now i have my turbo custom manifolds that'll only need a flange change already running megasquirt so all i need do is swap engines over and as done in bits don't notice the cost as much and i'll still have my steel cvh to sell and get a bit back to put to the zetec but thats just the way i went about it and you can still have a working car as you do it rather than it coming of the road for months and a lot of people lose hope doing it in one large/daunting task
