Anyone know where to find parts for internal upgrades?

 

Which parts specifically? Searches would answer most, but it really depends upon what you need.

 

Start here >>> http://www.roadracemotorsports.com/drivetrain.htm. Searching also helps.

 

Ive tried searching and havent found a damn thing... I tried RRM but I am looking for valves. My buddy just picked up a head for $50 and two of the valves are bent so we are looking to find some performance valves, camshaft, springs, etc... all head parts.

 

There aren't any performance valves for the 4G94 heads. If you want, you can get oversized factory valves. As for everything else, try here >>> RPW.

 

Yeah, that's why I asked. RPW MAY have valves, but if not them then I dunno who. Can our valves be cross-referenced with any other Mitsubishi motors? If so that may be our saving grace. The only other option I can think of would be sending a sample valve off to a shop and having them make a one off aftermarket part. If and when you DO find this out, please let me know. I've got a couple heads I'd like to rebuild myself.

 

Here's the cross reference for matching intake and exhaust valves:

CA5A
CB5A
CJ5A
CK5A
CS6A > US 4G94 Lancer
N11W
N21W

Most of these are just the 4G93 engine. The first couple are Mirages and Colts. The last ones are the RVR. Hope this helps.

 

How do chassis codes reference intake/exhaust valves? Wouldn't it be easier to go from actual engine codes?

 

Well, 4g93 cross-reference means we may have an aftermarket. May wanna check the Mirage forums or at least check with some of the Mirage guys on here and see what they've done. I'm SURE they have upgraded their valves, because I know there's at least a few ridiculously boosted Mirages out there.

EDIT: Now that I think about it, do we have the same valves as the 4g93t? They may not be available here, but that may be a possibility for some parts.

 

I know. It's weird. But that's how the Mitsu program cross references parts. Like Hobie said your best bet would be to look for parts for the 4G93 Mirage engine. It's been around longer than our 4G94 and has many, many parts that carry over. And most of those Mirage guys are crazier than us with upgrades!! They'll steer you in the right direction.

 

I agree with what he^said

 

thanks for the help, ill be sure to pass it on to my buddy

 

Bump so I can see it... ?

 

What did you want to see? I never saw this forum until it came up on the Mirage board .... but then I did have myopia when it came to the board. I was in Lancer only until I got the RA (and people started being dumb in those forums) and then I browse the RA forums now and again.

I can get you a part number for some valves, allegedly oversized for the Mirage, I think.
