so today i was taking my head apart so i can get it machined and start building it.
and i think that after taking off my cams and taking a good look at them they look after market at least i think so, they bothe have number and stuff and "FP" on bothe cams.

My fp2's looked like that. I don't remember what the numbers were though.
 
Take a picture like already stated. I have stock springs/retainers with my fp2's and so do many others.

Looks like you are running a bit on the rich side. As far as wondering if you have the right springs or not, I would recommend taking a couple of springs out and measure the pressure at installed height and at .500" lift. This will tell you whether you have aftermarket springs or not. (You may not be able to verify just by looking at them).
 
Its been awhile since I had my head apart & its hard to tell for sure from the pics (no specific stand out features if they are aftermarket) but I'm thinking they may be the stockers. Best way to know for sure is to pull a couple, have the spring pressure measured & weigh the retainers. If they are a common aftermarket titanium retainer you should farily easily be able to tell just by holding them, as they are basically weightless compared to the stockers.
 
any idea on what stage cams this can be "size"?
i email fp but haven't got anything yet, and sens i got bc spring and retainers on the way and valves. if this are after market ill get them cleand up and use them, if not ill throw the bc ones on it with the fp cams i got but i just whant to see if they can be compared to bc or hks 272, sens they are the cams i was planing on getting.

and thanks every one for the help?
 
so today after i find out i have fp cams, my friend comes over and we thought about taking a look at the comp cams the guy he bought the motor as tolled him about it head and also the arps, my friend always questiond him self about having cams becouse it idels like stock.

so after taking a look at it the only marks the cams have are d1 and d2 and on bothe cams its got that number EP4604 nothing else . so we compared it to my cams and my cams also have the ep4606 but with all the machined numbers on it and fp also.
and about arps its got a regular bolt on it maybe a 14mm not sure / didnt check.
so im asking for opinions about this cams stock/or comp cams?

Send a Email to FP and ask. They would know if it was theirs.

Those are aftermarket cams by Forced Performance. Forced Performance Turbochargers

They are a reputable company.
Nice find.

My FP cams look similar. But is that an FP or an EP on the cam in the very first photo in the thread. All FP grinds are from Comp Cams. And all Comp Cams have CWC stamped in large font in between number 3 and number 4 facing the other way.

All fp cam part numbers have the letters FP in the middle and are on the first line in between number 3 and number 4. Mine has on the first line 101-2FP-8E which is the part number for the FP2X cam grind. Under that line is the serial number. Mine is UN5504-05 The number under that is raised lettering which DOES match yours: EP4604. It faces the other way.

Those are not FP cams. But they could be comp cams. Contact Comp Cams.


. . . You should have done a little searching: dsm guy with xe258hr comp cams. Apparently that is a grind number. FP doesn't put their grind number on the cam, I don't think. The 258 in the grind number is the advertized duration (@ .004" valve lift). Fp2X cams have a advertized duration of 259*. And the grind number is 259HR-107+9. Comp cam 101300, or XE258HR-111. 111 is the centerline degrees. These cams have more overlap than the famous 101200 comp cams, which is similar in performance to fp2 cams or hks 272 cams. This is like fp3 cams but with lower lift and probably less ramp rate. Both have an exhaust cam retarded about 5 degrees vs. their 2.0L cam counter part.

EDIT: Also, this cam should lope a little more than the 272style 101200s. They have more overlap. They should give you a faster spool. But if you're pushing your turbo (higher backpressure than boost), then you will run out of topend earlier than with the 101200/272/fp2 cams. They will display more topend power than 264s/fp1s/101100s, however. I think this is a better way to have a balance between 264s and 272s. Again, idle quality is not quite as good.
 
the first cams are the one i had in my car and they bothe have the fp on them + the machined numbers that you guys cans see from the images.

i was asking about the second cams that i posted, they belong to my friend, becouse they have no marking nothing that it can tell us if its after market or not besides the d1 and d2.

and yes they tolled my friend the motor had after market cams but also they said it head arps but if you look at it its got a regual nut.
 
Ok. Well FP can definitely tell you which cams you have in the car if you call them with the numbers. As far as the other cams, maybe someone on here can identify the manufacturer/distributor.
 
OH! I was confused. Those second cams are not stock cams. Stock cams do not have those markings or anything close. Doesn't the owner have a receipt of the cam purchase? All cams have cam cards too. That raised lettering, EP4604, is the same letters and digits as my fp2x cams (which are similar in duration and centerline to 101200s). . . Could these be comp 101200s?

We already know what cams are in the first pictures: 101300s. But I didn't think FP just rebadged the Comp Cam grind. ? ? ? I thought they had their own specific grind that they have Comp do. . . Those first cams are NOT fp3s nor fp3X cams nor fp4 cams. They have lower lift and different centerlines. . . But they ARE stroker cams, becasue they ARE 101300s but with FP etched on it ???
 
so let me get it clear the first set of cams they are for a stroker motor, and thes econd ones are not stock but not sure ### brand they could be!

as far as the first cams beeing stroker cams is that ok beeing on a none stroked motor?
 
As I mentioned, your boost will come one quicker. It will be more of a "hit". But if you push your turbo where your back pressure is higher than your boost pressure, then you will have less topend with these cams. They will lope more. If you want these to perform like 101200s, advance the exhaust cam 5.5 degrees and retard the intake cam .5 degrees. . . I wouldn't worry too much about the .5 degrees on the intake side. Just one adjustable cam gear is neccesary to get it close enough to 101200s.

But as is, you will have more streetable spool and midrange with these cams than 101200s/fp2s/hks272s, more lope, and possibly some strange idle o2 feedback. More air is slipping from the intake to exhaust at idle, so your o2 feedback will think you're running lean.

wait! so its got a nut? or a bolt? If its a nut, its ARP, bolts are what come in it stock. Your confusing:beatentodeath:
 
it sounds good to me i was still thinking on spending money on some hks or bc 272 but this sound like they will get the job done just as good, about retard + advencing time i have the hks cam gears that wont be a problem doing but as you stated and im not going to worry about just .5 degrees.

the turbo will be a gt35r as it will be my everyday car + track every now and then, id it possible to get to the same hp number with this cams as other?

i really wanted a cam thet came alive soon but still had some top end also, and be street frendly for my every day driving.

and thanks for every ones help

ps:philla yes i meant a bolt. im getting confused my self im asking questions for my self and still wanting to find out about my friends cams.
