Hi Guys has anyone drop in pistons, rods and rod bearings on the evo 9. If so is the procedure at all different then the evo 8? I feel like I heard the way the pistons rings are placed differently, but im not sure. thanks in advance...


Also if I have 20k on my car do you think it will be fairly safe or do I require pulling the crank and balancing it?

Also do you guys think Cosworth bearings are any good for drop in?

Call buschur. I did their drop ins on an evo 9 and everything fit perfect. It is the same procedure as an 8.

 

A lot of people do the drop in upgrade (mainly on a budget). As long as your bore is good then there should be no problem at all. The MIVEC plays no part in this upgrade. The block has different oil ports to the head which houses the MIVEC intake cam gear which is the main difference between the EVO8 and EVO9.

I would recommend ACL Calico Coated bearings.


Good Luck!

 

i am doin the drop in pistons and rods on my 9 with buschurs je pistons and crower rods!!! hopefully everythin goes well.

 

I wouldn't be able to sleep at night if I just dropped in a set of pistons...piston to wall clearance does make a difference.

 

i did it on my evo 8 with 35000 miles. runs fantastic!
