What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What is the maximum valve lift these springs can handle?
The Mitsubishi 4G93 DOHC Single Valve Spring Set is designed for a maximum valve lift of 11mm. Ensure your camshaft specifications align with this limit to maintain optimal performance.
What are the seated and open tension specifications for these valve springs?
These valve springs have a seated tension of 90 lbs and an open tension of 215 lbs at 11mm valve lift. Proper installation and measurement are crucial for maintaining engine performance.
Are these springs suitable for turbocharged applications?
Yes, these valve springs are specifically designed for turbocharged applications on the 4G63 and 4G64 engines. They provide the necessary support for higher RPMs and boost levels.
Do I need to modify my cylinder head to install these springs?
No modifications are necessary for installation; these springs are a simple drop-in fit for the specified Mitsubishi engines. However, always check for proper clearance and fitment during installation.
How many springs are included in this set?
The PS-3506122-16 set includes 16 valve springs, which is sufficient for a complete engine build or replacement in the specified Mitsubishi engines.
