Is this for real, everything I've ever heard says the longblocks are identical between RA and X

In case anyone is not familiar, John at English Racing is very respected in the Evo world.

 

hrm... first time i've heard that one ...

 

Also, the reason I bring this up, is it can/would have a material impact on how we should mod our cars.
For example, on an X with a stock turbo, the stock cams are very well suited. Upgrading to an moderate MX1 or S1 has shown a gain of 20-30 whp on the top end. Since it costs upwards of a grand to buy/install, they are not considered cost effective.
Additionally, I have been racking my brain try to figure out why it is I can't get the top of my car to breathe. I can make as much if not more than most MR tune I see (same fuel, boost, etc) until 5500 the whp stops rising, whereas on an MR it will keep rising until 6500. Based on what has been done on MR's, and our knowledge of the long blocks being identical, I had decided cams might not be worth while.
BUT, if we do have smaller cams than an MR, now the gains become more like 50-60whp and the cost begins to be justified???

 

On mitsupart catalog they are listed differently but cost the same. And if we make the same power as the x with the swap I don't get it?

 

Wow, so I'm looking at the Catalog, apparently CA has different cams for the RA? WTF...?

EDIT: I can't read w/o Ralliart
So then 2 set of cams for Lancer w/o Ralliart (CA and everywhere else) but only 1 set for all others (RA and MR/GSR)?

 

I did the online parts lookups, but, as mentioned, the cams for the RA and Evo are listed separately, and have identical prices. Unfortunately, I was unable to extract an actual Part # from any of the sites I found. So, the separate listings essentially mean diddly.

I just found a listing of part #s that I can track down ...

 

John Bradley said he will check the specs with tmw. hmmmm
Either way I lose, my cams suck or tuning skills above 6000rpm suck

 

I'm almost 99% positive chi already checked out all the drivetrain parts through his computer system at work.

 

....

I don't know if I would consider this "definitive proof" but I did find some part numbers here:

The RA part numbers seem dubious since none of the sites want to pull up which car it's for in the part info like they do for the EvoX cams.

***EDIT: redacted the part numbers I originally posted. It's best not to perpetuate FUD.

 

I'm 99% sure they are the same cams.

 

Thanks for the info Bryan.
If the cams did turn out to be different I was going to shop for some Evo X cams. =)

 

The cams are identical. I had this argument on the other site and looked both cars up on the Mitsu CAPS database. Part numbers were identical as of that posting, so I'm not sure why nunyas' numbers are showing differently now

 

nah... it was because the part numbers on the other site were mis-written/mis-understood when they were gathered from their sources. the exact original numbers didn't pull anything some manipulation of the numbers to make them resemble actual Mitsu part numbers ended up pulling information, but the information was not vehicle specific in the descriptions. So, it's highly likely to be unreliable.

 

(sarcasm)

And yeah the rear differentials were also always assembled according to spec.....

 

Part #'s and assembly are two different things.
