Alright so I have a 1999 Pontiac Montana. I wanna know what 4 cylinder engine will fit in it. It has the stock 3.4L engine and I just wanna go smaller on it. I know all of them have only V6s in them and was hoping on going smaller. AKA kids and a lot of driving lol. I�m a car thinker and I wanna see this happen. I have a 01 cavalier I�m going to use as parts and hopefully I can easily drop that engine in it if it�s possible. If anyone out there knows anything that would be great. I�m hoping the 2200 engine from the Cavalier can go into the van with ease. I know modifying for engine mounts and new wire harness but what should I look out for and what I can do to make it work. Transmission from the van is good but hoping I can drop just the engine in the van.
