No... they send you someone else cam's that they re-did to their (cobb's) cam specs. Then when you get them and swap, you send them in your old one which they upgrade and then sell to someone else and the process is repeated.

I don't think he was talkinng about cobb. I think he was talking about Crane/Crower...

right, I'm asking how to go about getting cams made that will mimic the performance increases in comparison to those offered from aftermarket companies.

JakeO

so..you're saying you can take your stock cams, send them off to a company that specializes in rebuilding them and get them made to the specs you want??? i guess then the real question is what specs do you need to know to have this done? I mean these aftermarket companies have dyno proven specs, so how do we figure out what they are? anyone gone through all this already for the ej25? how'd you go about it?


aaa. ya call up crower thats who i went throguth ask for brain tell him your looking for yada yada yada then he'll say send those cams here he'll tell you what kind of duration and lift would be good for your app.
theses guys have been around since the beginning of muscle cars so they know there ****

Frank

thanks, i may just have to do that

JakeO

it made a huge diff in my probe it used to fall of the power band around 5000 rpm now it pulls all the way to 7000. i asked for a high reving cam and they told me the specs they were going to do to it and it they gave me the performnce i asked for jut tell them what your looking for

Rallysportz

How much did they charge you to do the cams? (is it a DOHC or SOHC?) Also, curious how long it took them to get the parts back to you...thanks

JakeO

they charged me 175 for DOHC app. and it took them about 3 weeks but i wasnt in any big hurry so i didnt give it anypriority

Rallysportz

So was that after a core refund or anything like that?? That's a good deal but did you get to keep your original cams in while they made yours or did you actually loose your car for 3 weeks? Could they order the part they need so you could still have a car while they build the new ones? I guess my cost would still be about the same since the SOHC on Subarus is still actually two cams (DOHC=4). Kinda weird...let me know- thanks

JakeO

mmmmm...... i had to send them my cams adn they ground on them. of topic but how many valves does my 2.5 have

JakeO

o ya... theres no core fund becaue they use your cams. but.... if you do what i did go get another set. its so much cheaper and you get what you wont at the fraction of the cost 175 compared to cobb's 1000 HELL NO. i would rather be out of the subby fora week or so.

Rallysportz

So you DID get a new (separate) set of cams for when you did it or not?

Your 2.5, along with all other EJ engines (all new suby engines are in the EJ line-up), has 16 valves or 4 per cylinder. 2 inlet and 2 exhaust for each cylinder.

I wonder what a whole separate set of cams would run me, then I'd have to add the grind time labor and all that stuff. Sounds like it would be close to $1000 anyway, everything said and done. I've also heard that the modified cams lose strength and are easier to break/bend- did you ever have any problems with that?

JakeO

i got mine back. onece they got done doing there stuff
in my case and mosltlikely yours to. what there going to do dosent make them any weeker. what they do on a small regrinde cam (in my case) is grinde on the back of the lobe. it kinda hard to look at it that way but thats how they do it. but if you strart going to the extreame they'll weld on to the lobes themsleves to where they need to be then thll polish the lobe to its smoth. make since

DoomE.Q.

That is what is said to cause the weakness on the Cobb cams. The fact that they are rewelded and grinded stock cams. Something about air bubbles caused in the welding process. Look it up. Seriously do a search.

JakeO

not trying to start a flame war or anything. i know all about the regrinding process. its a very rare case when they do get bubbles in there weld. (dont quote me on this) but thats only when there doing some very high lift and duration on there regrinded cams. in my case i only got 15 more degrees lift and .15mm more duration and all they did was grind the back of the lobe off. if that makes since.
