One fix at a time
You have to make up for the extra stroke somehow. The piston pin gets moved closer to the top of the piston. The customs pistons are worth it and not much more than others. I like the ring set that comes with them because they're definitely stronger/thicker than OEM by a long shot.I'm really considering getting a 92.5mm VR4 block, and getting the 74 crank worked on by Ray for the 3.5 setup. I like the idea of running tool steel pins.
Ray (or anyone else that can factually answer) I have a question: Is using your custom piston a necessity or can I use some other pistons?
Been thinking alot, just haven't committed. A few upcoming expenses are in order, but would like to set my VR4 up for a 3.5.
