Not sure if the advanced guys pay attention to the newbie forum, but here's my prob.
I have a 93TT Stealth (6G72) and want to go with a stage 3 head port. Problem is that the lowest price I've found was $2400!!! A new neighbor used to have a DSM and said that was crazy, especially since the heads aren't flow benched. Does anyone know of a good shop that deals with mitsu heads? Here is what's included in the $2400 job.
The Stage 3 Heads Include:
1mm Oversized Super Alloy Ferrea Valves
Valves are back cut and swirl polished for increased flow (Ferrea Super Alloy Valves were specifically designed for high boost/high nitrous applications where extremely high combustion temperatures are present - Super Alloy Valves are used by many Top Fuel Dragsters)
Fully Ported Intake Ports
Fully Ported Exhaust Ports
Enhanced Bowl Configuration
5 Angle Valve Job
New OEM Valve Springs
New OEM Keepers and Retainers
New OEM Valve Seals
Factory Casting Flaws Removed
Reshaped Combustion Chamber
(Unshrouds Valves for Better Flow)
Combustion Chamber Flaws Removed
(helps prevent detonation by removing hot spots)
Expect gains of up to 60hp at the same boost level you are running now, depending on application, and if the turbos you are using have enough flow left.
