This is a solution that in computers we know and they have started to do this in cars. Find and use a copper headgasket. Copper is the cheapest and most effective way to transfer/displace heat. They may have them around for the 2.5/2.2l 4's in your car. I used to own a 2.5l dodge shadow ES. Here is the difference in the 2.2 and 2.5. The 2.2 has a shorter stroke thus it is more tuned for a preformer. The 2.5l has a higher torque curve cause it is a long stroke high torque engine that can and has been used in trucks too. IE: The dodge dakota 4cyl. That is the difference and it is all in the head for the models in either 87, 88, or 89 - 94 (can't remember first year put in) when chrysler went to the common block which worked with all heads. before that they had a 2.5 that had a tall block but same head as the 2.2l so remember early engines had different block. later engines had different heads. Me I have the mitsubishi engine SOHC right now in a dodge shadow ES 1994 I bought after I wrecked my 1992 dodge shadow ES 2.5l. The mitsubishi is the same bottom half that sits in both the 3000gt and the dodge stealth (the 6G72). My 5 speed transmission is the Getrag A543 and I want to find the Getrag A568 or A555 to see if it will match up to this engine considering both these transmission have sat in the same types of cars 4 cyl or v6. I need these either one of these transmissions for my project cause they are the only ones I can think that can handle what I am going to do. I am going to make my engine the same as the Mitsubishi 3000gt vr 4's, twin turbo! either that or I may go with the 3000gt's 6 speed transmission in recent years. but I'd rather have the getrag. I need some help locating this transmission. Can someone help?
Thanks
