Hey everyone, hoping to get some insight and clarity on couple of questions!
I’m in the middle of planing/building a 4g63 project to hit 1000-1100whp. This is my first time building such a high horsepower engine so i do not want to throw expensive parts at it without any idea of limits.
1. Headstuds- will M11 CA625 be sufficient or should i switch to 1/2inch?
2. Headgasket - HKS or Athena cut ring style headgasket is enough to hold the cylinder pressures?
not really set on the turbo yet but thinking of 7675 or similar
3. lifters- can the hydraulic lifters cope with 10-10500rpm or should I go with Solid lifters?
I’d really appreciate your input and thoughts!
For lifters I don't believe that solid lifters will necessarily "aid" in handling rpm as much as avoid certain downfalls of hydraulic lifters. Both types have their benefits and detractions.
