intake and exhaust valve comparison	Sign In

I have a 92 Stealth with a 24 valve Mitsubishi 3000gt engine (6G72) that the timing belt has gone in. I have done some research on valve replacement and have all the info on how it is done. My one question is: is there a difference between the valves in a turbo engine as opposed to a non-turbo engine? I know that there are different diameters and am taking that into consideration. I have found that valves for a turbo are slightly cheaper and this is why this question came to mind.

I'd send all the parts (sorted out for location) out to a machine shop to check and measure everything about it. Trying to save a buck now just to do it over again because you missed something wont be a bargain at all,

You should takes Tom's advise and have a machine shop do your work. If your belt broke & you bent valves, then the guides need to be checked & the head pressure tested for cracks and then resurfaced....

It good to try to save money & keep the costs down, but some corners shouldn't be cut, but you don't want to go thru all this work to turn around & have to do it again.............

You need to listen to these guys. They are trying to save you a whole bunch of hassle. First of all, you can't spot a bent valve with the naked eye. Second, you can't just pop different valves in there without lapping them in or grinding the seat and you won't know which it needs.
