What is a street able motor (valve train) set of materials that could sustain 7k rpms ?
So, what valve material, spring materials, push rods, lifters etc. No ceramic lifters unless they are out on the market again. Rich |

So Jake, I assume that the FA20 motor in the Subaru BRZ gets it's 7500 RPM redliine because of the DOHCs?
And possibly the fact that it is a "square" motor (86X86)? (IMG:http://www.914world.com/bbs2/uploads_offsite/i366.photobucket.com-10819-1378824844.1.jpg) In my other thread, I posted a motor for sale for only $3k that I thought you could have some fun with. Stu |
