Default 282 NON-AVCS Cams (who sells them?)

Been looking for some cams for my build.
Looking for some 282 cams in particular. Been looking around on Kelford, GSC and BC's websites but can't seem to find the 282 in non-avcs that would fit a ej257.

Anyone have any idea who makes them?

Thanks
-Ben

BC sells the same cams for both applications. You just take the set screws out of the oil passages if you want to use avcs.

This is correct. BC cams, even the "282," are tiny. I don't know about the Crower ones, however.


As for the original question, the EJ20 and EJ25 cams are going to have a different lobe separation angle designed for the time spent at TDC of the specific crank being used. I use a 75mm crank (EJ20) and thus picked a cam designed for an EJ20. If you are using a 79mm crank (EJ25) you are going to need to talk to a tuner/nerd who can tell you whether or not using a different LSA is going to be an issue.

You could always buy an AVCS cam and have a machine shop tap and plug the AVCS holes. This would be pretty easy for any shop. (You can DIY also, but I personally wouldn't go into my garage and drill holes in a NEW $1000 cam set)

If you order from Kelford they will do custom centerlines on there off the shelf cams for no additional charge. This is another way to get the proper LSA without having to plug a set of AVCS cams. Only down side is shipping to the U.S. is a bit pricey.

If you decide to run non-AVCS cams in AVCS heads you will need a cosworth cam position sensor bracket and you will use non-AVCS cam seals.

The cam centerline is the same for the exhaust cams whether they are 257 or 205 specific, the centerline for the 257 intake cam is variable due to AVCS and usually 113 for most of the 199 series Kelford cams. The only difference really in specs between the 205 and 257 variety would be the AVCS option.

Whether they are 205 heads or 257 heads they can be fitted with either cam and made to work.


EDIT: this is for single AVCS 257 cams ^^^

Thats what i thought. I have seen a lot of people puting ej257 cams into an ej20 head without any problems except for having to tap another hold for the cam gear to fit correctly.

It would think that using ej20 cams in a 257 would work with minor modification as well.

Kelford 282 EJ20 non avcs cams are in stock. But the 282 EJ257 AVCS cams are not in stock until september 20th. Just want to know if i would get the same result with eitherwrx or sti camshafts if in not running avcs in my ej257.

On the fence about which of these Kelford cams to go with:
Can someone explain the difference between the two besides each having a different lift.

the L cams are a little more aggressive and have more lift and need cyl. head modifying due to the size of the lobes.The g cams are a drop in and will net close to the power potential of the L cams but without all the added machining expense.The L cams will be a little harder to dial in the idle on due to the aggressive ramp and duration.

Its so weird...a friend of mine has 272 Kelfords in his STi and he needed some machining so the lobes would clear. So the G cams dont need any modification to fit then...

Kelford makes more that one 272 cam. 272 is just an "advertised" duration and has nothing to do with the many other cam specs so not all "272s" are equal.

^^^^exactly what is the true tell off the aggresiveness of the ramp is what the duration is at .050,this tells you how fast the valve is actually being opened.And yes with the smaller lift of the g's they should just drop in with no clearancing.
