Cams...oe/264?

[324vr4]

Has anyone ever tried swapping the OE exhaust cam with a 264? I know the most oomph you get when swapping cams is with the 264s; for for more "up top" the 272s but I'm curious how OE/264 would perform...just pure curiosity is all

Not worth it.

 

[habitatguy187]

It would cause better spoolup and torque curve wouldn't it?

 

[1G-3G Eclipses]

Not worth it.

Anything to back that up?
You gave absolutely NO reason as to why it wouldn't.

But I would imagine it would increase spool up though.

Just get the cams from the 94 Galant GS, they are 260/264 and you won't be disappointed.

I hadn't heard about that. I would imagine you could get those fairly cheap too!

What are the stock ones?

Got anymore info on these?I've never heard this either.

any info, i really would like to know, i really could use some more cheap upgrades for my talon

What are the stock ones?

252's i think

edit


found the part numbers

inlet cam: MD335760
exhaust cam: MD190853

and from which motors
1994 Galant GS and Euro NT 4G63 and 4G67.

The Galant Center - View Single Post - heads any big diffrents nt and turbos

I don't understand why you'd wanna swap out the exhaust cam only? I think the center lines would be to different to work properly together. I suppose if you degree'd the cam in you'd see some gains. Nothing to call home about but I feel the mid range (3500 - 5500) would be improved. Do you have a cam card for the 264 you where talking about? Every company's 264 cam grind is a little different or they would all be getting sued for copying each others products.

Given the fact I have 264s and I tried that just for the hell of it, yeah, its not worth it.

i'd really like to know if the galent cams would work. that seems like a really good, and cheap upgrade!

The AMG tuned N/A Galant has 260/264 also.
I don't know if they have the 2 deg advanced centre line like 252 N/As
Cheers !

 

[324vr4]

Interesting, never thought the AMG tuned Galants had such different cams...granted it was NA...I am going to degree my OE cams and see what numbers I get and if I stumble across some NA 260/264 cams I'm gonna try them...I'm fairly certain the spool up time would drop dramatically or at least be noticed by your ass while driving...might be a worthy experiment...thanks for the advice and suggestions y'all....

Big ol' BUMP!

You can't install those n/a 260/264 cams in your turbo car and expect them to have remotely the same performance advantages as a set of TURBO 264 cams. What's the ramp rate, what's the intake cam advance, the exhaust cam advance, the lobe separation angle, peak lift. . . I will guarantee you that a set of cams build for n/a applications will have much more intake cam advance, lower lift, less, lobe separation; all these are typically not good for turbocharged application. Mitsubishi likes to set their n/a cams up for low end torque it seams to be something they always do with their motors all through the years.

Mysticj posted the specs in a 4g61t.org forum here. The lift is very close to stock, not nearly like typical 264s. And the timing is definately not something I'd do for a common turbo setup. So after hunting down these amg galant cams and probably paying a bit more than oem used cams, you will have to buy a set of cam gears for $200 to get the timing to work well with your turbo application. Then you still only have slightly more lift on the intake than stock, with less duration than 264s. You can get a set of 264 or 272 regrinds for under $200.

+1^ The exh cam would need retarding if you use the 260inl/264exh n/a's
I'm running the 260inl & a regrind hks 264 profile exh < retarded. DD VR4
HKS 264/272 in the Lancer Matt.
Cheers !

Lobe Angle:
Intake=112*
Exhaust=111*

You are right, each galant gs cam is $200 a piece from the dealer. When I swap out my busted GS head with a 1.8L Hyundai one, I notice the letter "G" stamped on them when swapping the cams out.

 

[dsm-onster]

Lobe angles are based on advertized duration divided by two, then adding the intake open angle. That comes out to 148, not 112 or 111. The stock 1g cams are 149. I think 264s have less angle than that, to give you an idea of where you want to go with lobe angle for a proven turbo cam.

Well said, I couldn't agree more There's much more to a cam than lift and duration

I tell ya, I hear more stupid ideas on tuners in a week then I do in my entire life. Is it a thing about being different or being cheap? 264 cams have stock spool, you aren't gaining a thing by doing it except compromising performance for zero driveability gain.

 

[mysticj]

The cams max out around 6800rpm on a 2.0L, I'm unsure on the 2.4 since my redline is 6300rpm with the rev limit @ about 6800. It might be slightly higher[powerband] with a shorter IM like the Evo3/RVR SSG. My cams cost me nada, finding them in the junkyard for a few bucks maybe worth it but not buying them from the dealership on a turbo application.

Do you find the size difference between a stock 252inl & 264exh the OP posted stupid ?
Or are you saying mysticj & myself are stupid for mentioning 260/264 ?
264 cams ? Are you saying the 264 Exh Cam has stock spool ? Inlet cam ?

 

[mysticj]

I wish I took pictures of the cams, I'll do it next month or two went I have a chance.
