Does anyone know what or if theres any differences between the 2.5l dohc motor and the 3.0l dohc motors? both are n/a of course and the 3.0l is out of a stealth and i have now a 2.5l dohc mitsu motor.
is there any difference at all that i need to swap over from the 3.0l to the 2.5l? and what timing belt should i use or will the 3.0l work fine?
thanks

They made a 2.5L V6 that looks identical to the 6G72. I forget the engine code. I'm not sure if he is talking about this particular one, but if you are there should be no real differences and the swap should be straight forward. The main difference in the 2.5L engine is the cylinder bore. The stroke is the same. I believe the timing belts are the same as well.

I had a customer come in my shop with one of the 2.5 engines. We swapped in a twin turbo 3.0 in it with no problems. His car was a turd with that 2.5 in it though LOL
The swap is straight forward with no mods needed.

It matters because often new forum members post in the wrong section. Your first post didn't give the information needed to correctly answer your question as the question wasn't clearly stated.

:offtopic: Yea new to here but im not stupid. I only posted here because there seems to be more members with v6 powered dsm's unlike other forums. The vehicle one owns should have nothing to do with what one talks about, thats why I asked what the differences are, not if its going to swap over or whatever to my talon. I have 1 talon a supra and an accord, soon to have a 240sx or maybe a fd3s, have plentyful knowledge on all of them enough to make them monsters. and by the way it was clearly stated for i only asked one simple question.. :offtopic: Aside all that now, :rolleyes: the motor is ready to drop in so thanks everyone else for helping me figure that out. BTW that engine bay is kinda tight with that in there.. :liebe011:
