Engine/Transmission (1994 - 1998) Some questions about souping these engines up

[sparks57]

Here is a long list of questions I have come up with while searching the archives:



#1: When you use ceramic coated pistons, does that allow you to run hotter without worrying? Basically, is the piston head the only thing that burns when the EGT's get up there? And does the ceramic coating eliminate that?



#2: If a 3k rpm governer spring is good, isn't 4k better? What is the cost difference? With the 4k rpm spring, would you need to do full engine balancing? I know that 4100rpm is a bad thing to do...



#3: If one were to set up twins on a 12v engine, what would be a good combo of compressors and exhaust housings? Would a PDR40/14 and an HT3b/23 be the most common and best option?



#4: What is the advantage of a copper head gasket?



#5: What is the difference between main and head studs?



#6: What would you gain by going to marine pistons?



#7: Are the two basic things to do to the p7100 DV's and cam plates? Are there any other gizmos for the fuel system?



I'll probably have more questions, but that's it for now! Thanks everyone, and sorry!

Ha! I knew I'd come up with more:



#8: What is "C"-ringing? Is it different from O-rining? Also, can someone please explain Fire-ringing the cylinders? Should all of them be done, just one, two... what?

While we are asking Q's, are there two piece pistons that use a forged steel or cast iron top with an aluminum bottom or skirt? And if so, are they more tolerant to high EGT's? Maybe that it what a marine piston is? Jordan

We can make this a n00bie thread!
