Any suggestions on best bang for the buck on a remanufactured 951 DI? Looking at SBT with 2 year warranty vs PWC Engines with 2 year warranty. Looks like $700. in savings going with PWC. Already purchased one 951 for my 2000 gtx carb. from SBT two years ago and it is doing great. Last year had one cyl. go on the DI. Did cyclinder exchange with SBT. Sent me one with .5 over pistons. Two hours in it smoked both pistons. Looks like Raves hit. SBT said it shouldn't have but thats a different story. Just looking for some good ideas.
