these cams are stamped as bc102, the box says bc102, the cam sheet inside the box says bc0102 are advertised as 280s.
they are not 272s. also, they are not new as in the above pics, they are rusty and cannot be put in as they are. they will need a polish or something...

i wanted 272s and waited for a set to come up, if i wanted 280s. there have been a few for sale previously. i didnt really want to try to go over emissions with 280s and a 2.4 when meeting limits for a 1.5.
looks like i going to be running the 280s now...

please guys, just get pics of what you are buying, and sellers, have a good look at your gear and ask if you not sure. there are heaps of guys who know about this stuff and what it is.


i will say that the springs and retainers in the deal are as advertised.
 
That's the chance you take when you buy second hand over the Internet, been there done that and you learn to buy new...
 
Thats a shame mate. What kind of packaging were they in when transported to you? And did the seller sell them as 272s?
Cams should always be lubricated with oil and kept away from moisture and exposure to air otherwise they will begin to get surface rust on the lobes. Polish them asap and look for any signs of pitting or scoring. If all is good then sell them on and get exactly the cams youre after. No point going the bigger cams then failing emissions and have to go through changing them again. Even though it is a 2.4 and the 280 overlap wont be as harsh, keep in mind you have to meet the ADR 37/?? emissions for the 1.5 efi engine for the year model the Jumbuck was manufactured. So unless you go E85 fuel, your best off getting cams better suited to what you need now to get the car more emissions friendly for a better chance to pass the IM240.
Whenever I remove cams I immediately wrap them up in an oil soaked newspaper like fish and chips, then wrap them up again in a towel for padding and protection before transporting anywhere.
 
Oh and thats pretty slack of the seller not to be up front and honest about it especially when its obvious that the cams are 280's. For my mind its not negligence, its blatant disrespect to sell something off knowing that its not what the buyer requested.
Does the seller have a good sales history in the forum? I believe we should name and shame so people can be wary when purchasing from this seller in future.
 
Yep, them the breaks.
I will try emissions with the 280s but may have to leave the stock n/a 2.0 cams that are in the sonata head.
I think I can get away with just a 5 gas test and no im240
I know the 2.4 will mellow the 280s and the bcs are mild as far as 280s go as well.

They were in opened packaging, in their onion bags. I have oiled and repacked them. Next time home I will clean them up, and check them closer. I think they will come up fine

I'm sure if the seller knew they were 280s he would have sold them as that.
 
Huh? The cams are stamped, the box has a part number description and the tech sheet all describe 280 cams. How much more info does a seller need when listing them for sale? Id be livid with the seller if they were sold to me as 272s or at least ask for my $$ back. Youre a better man than me Jack lol.
 
Jack is a nice bloke....and has the right to be angry, I would be.

Im pretty sure you would have contacted the seller over these issues Jack. what was the response....good... bad or indifferent? We havent heard from the seller here ...so I guess we need to know

on the other side of the coin Jack....I have some 272 BC cams if you need them to be 272s. They are new and unused....we could work some thing out I guess
 
Jack you've been pretty helpful to me in the past, maybe now is the time to repay the favour.
I have a set of BC272's oiled and wrapped up as Rob mentioned as I won't be building my engine anytime soon.
We don't have the emissions testing problem you do down there and with the extra duration (they're some chunky lobes!) it'll only help my engine have a higher RPM ceiling theoretically :p
I don't think that much rust is really such a problem is it? It doesn't look very deep. I'd have just wire wheeled it and assumed it was good to go....Lol maybe I'm too much of a bushy. Haha
If you're really stuck and you really wish to use 272's I can swap you. Let me know buddy.
 
i think the rust wont be a issue either, i not home for a bit, and will wet and dry them and inspect. im not going to swap them till i have a look and inspect them.
thanks very much for your offer.

also i need to research a bit more. cause those 280s do sound FAT. maybe i can get away with them.
also, was concerned with the available vacumm for the brakes. I will be auto so that was another selection reason for the 272s.
 
so, any inputs on this?

am i going to be running out of vacumm with my proposed combo of 2.4, gt35r with 1.06 tail, w2a intercooler and auto with bc280s. thinking of compression of 8.8:1
i hope to pull to 8k rpm. are the 280s a better choice than the 272s.

i am sure that here in wa we have a 5 gas test for emissions as there is only 1 im240 tester in wa.
 
mdk87 be carefull man as of november 1 we will have the same system as the boys down south.


i just got told my coupe has the wrong code on it's blue plate when i applied for approval to do my awd conversion and as a result had my application canceled and must have the offending blue plate removed (a crap load harder to do then get the frigging thing). and to reapply for mod approval under VSB14 guide lines!.

I know a guy who does plates easy and legit also at a decent price. He noted all the mods I've done on my lancer.
 
it's ok man i actually had to enlist a automotive engineer to certify the structural integrity of some of the work i need to do in relation to the awd conversion. so far he's quoted $500 for his time but im budgeting on double that with all the messing around!
 
on november 1 qld officially adopts the national code of practice (NCOP) VSB 14. as far as i know qld was the last state to sign onto vsb14 everywhere else has had the vsb rules for over a year.

I was thinking , does the 272 and 280 have the same lift as could you just use vernier calipers and measure the lobes.

I'm only adding an idea I had.

Good luck working it out.

They don't have the same lift, 280 has slightly more. Yes you can use verniers to measure from base circle to the toe, and yes it would indicate the difference however it will be a bit hard to tell if he doesn't have a 272 to reference that measurement with.
I think the fact that the 280deg part number is stamped into it is a pretty good indicator lol
I'm still wondering how much that rust would really affect it?
