I just purchased a 03 Evo about 2 weeks ago. I bought as is from a Mitsu dealer about 1.5 hours away from me. I've been going over the car making sure all the work done to it was done correctly. When I pulled the valve cover the first thing I noticed was the aftermarket head studs. I assume they are ARP but I don't know for sure. Also the top 2 or so coils of most of the valve springs have blue paint on them. I was under the impression that the stock 8 cams have holes drilled in them but I could be wrong there so I thought they were aftermarket cams. I tooks some pics of some markings on the cams. There are some orange dots on the cams as well. If anybody could identify these cams I would really appreciate it. Also on the backside of the intake cam the numbers 261225024 were what seemed to be stamped into the cam.

 

anyone?

 

I would definitely say that those are aftermarket cams based on the fact that you have FIC injectors. I know that the IX cams are hollow, but not 100% on the 8s. Valve springs usually have paint on them to distinguish between intake and exhaust. Sorry i wasn't much help but good luck.

 

Those are definitely aftermarket cams, but the maker of the cams I don't know. Very few Evo owners would install headstuds and injectors without installing aftermarket cams of some sort.

 

Thats exactly what I was thinking. Parts wise the car seems to have the good bolt ons. 3" tbe w/ testpipe, megan o2, trunk mount battery, short route upper pipe w/ ssqv recirc'd, spearco intercooler, fic 850's. It also had a fuel lab fpr but I have replaced that with the stock regulator and lines. I pulled the rom that is in the computer and it is a factory rom that has been modified.
