I am planning to do some minor mod on my 2000 Lancer CK. My current engine is a 4g92 SOHC and I just got my hands on a 4g93 DOHC cylinder head. I plan to do a head swap. I read somewhere on this forum about a 4g94 head swap project using a 4g93 DOHC cylinder head. They used a 70mm idler pulley on that project. My question is, do I still need the 70mm idler pulley or I can just use the stock that I have? I am thinking that the 4g94 will need the 70mm idler pulley because it has bigger displacement than my engine.

 

I have a 4g92 lancer too, and I have a 4g93 DOHC head in stock, I also want to make this change, I also need instructions on this

 

Any chance you remember the part # for the 70mm idler you used or need?
