trying to put a set of tuner1's in my b16 head. the exhaust cam is fine but the intake cam has a lobe that is hitting the head casting real bad. check it out.


there it is on one side, you can see it barely missed making contact with the head. that gap is honestly about 20 thou.


theres the other side, just barely misses making contact but this is after i took out a ton of material. it used to bind. im not real comfortable removing any more aluminum...


this gives a better idea of how much i had to take off so it didnt bind when rotating the cam. also notice how the cam doesnt sit even in the journal...


the problem could lie here. with the cam pushed toward the tb side the ring on the end of the cam doesnt fit into its slot in the camcap and it isnt able to be tightened



theres the markings just to verify. you can even see the intake cam sits very far to the front of the engine


there is lined up next to my itr cam. the skunk2 cam is the one on the bottom. you can see how that lobe sits about 1/16" to the left of the itr cam.

wtf

hmm. that is different. I'd contact Brian@skunk2 on here. Get those pictures handy, I'm sure he'd be willing to do something about that considering you haven't turned over the engine yet.

I think he removed the material from the head

non-VTEC

are they new or used? what are those black marks on the lobes?

ya i would contact skunk2 and see what they say....

Is it normal to have to remove material from the head for clearance with any cams?

m3tech95

Can you take a picture of the gasket on the cam gear side? Are those seated in properly? If those arent in correctly it pushes the cam over slightly you may want to adjust that.

Those definietely look like used cams.

blackeg

the cams are used. i dont have the cam seal in yet. never made it that far.

black marks on the lobes appear to be discoloration. the lobe itself is not scored or worn down.

i did remove material from the head. i did not see any oil journals in the vicinity so i went for it with the dremel. im pissed i didnt notice this before i bolted the head on the block it would have been much easier to clean...

my other b16 head is at my machinist getting freshened up for another motor im building. im going to stop by with the cam tomorrow and fit it in to see if it has the same issue in the other head...

Are they not real skunk2 cams? I dont think i've ever seen a set of cams that you would need to grind the head to make them fit. Thats just very odd

blackeg

Yea I was not anticipating this at all. If I had to take a little off I honestly wouldn't care but this is pretty damn bad imo.

crvtectim

Sounds like you're just wasting it on cams HA! Jk

blackeg

yeah right lol, last year my diff broke, my clutch glazed over and rainbowed the pressure plate and flywheel and my fan broke on the dyno resulting in some ptw contact and a .020 overbore. Its not just cams.

check out the last pic i uploaded today with the s2 cam matched up to my 01 itr cam that they were supposed to replace in my engine

crvtectim

Ouch, yea that's sh#tty! Were you not happy with the power made with itr cams?

blackeg

no i was more than happy, 440 on 16 psi pump gas with a t3 60-1. im building an lsvtec to daily drive and i wanted to use itr cams in it. rather than have 2 sets of itr cams for about the same price i got the tuner1's. research lead me to think i could pick up about 20hp just drop in with the cams. figured it would be a good deal to pick up that power with one of my cars for basically the same price as buying another set of itr's. damn me and my wishful thinking.

i think im gonna have a snow day from work wed or thurs and im going to put the engine back together and dropped in with the itr's again and figure out what to do with the tuner1's in the next few weeks

crvtectim

That sucks. Not much else to say. Have you made an effort to contact S2 yet?

Hasn't skunk2 stated none of there cams have the holes in them.

Skunk2 cams are chilled cast and do not have holes in them like Oem steal cams. Those are fake skunk2 cams brother. Sorry to hear that you got taken but those are fakes for sure.

I just put a set of skunk2 tuner 1 cams in my GSR turbo like about a month ago and they didnt have the holes on them like yours. Sorry to say those are fake skunk 2 tuner 1 cams you have there. Brake them in half and end the cycle... Watch the video in the link below, that should answer your question if your still in doubt if there fake.

Fake skunk

blackeg

figures. are they like blox's or something

Natural Aspirations

I also have a set of these same "skunk2" cams. Bought them from a HT member ( Nathan Thompson from Kentucky ) that refused to refund my money claiming they were legit. Where did you purchase these?

Natural Aspirations

Blox are the same material and supposedly the same cam blanks the skunk used previously.

blackeg

got them from matt mcmanus (pgpbubble on here) out of jersey. he text me a pic of the h01 on the end of the intake cam so it seemed legit. **** me for believing that people are honest. he went awol for a few weeks no tracking # then they just showed up one day about a month after i paid for them. i took a quick look just to make sure the lobes werent worn down and put them on the shelf for a few weeks.

i did measure the intake lobes vs my 01 itr cams with the dial calipers and they were a lil bigger with what appears to be similar duration.

im filing a claim dispute with my cc company tomorrow (hope for the best) and now just curious what cams they actually are

Natural Aspirations

Yea mine measure out fine as well.

I haven't taken the time to test fit them.

blackeg

lol i wasnt planning on having to test fit them..oh well. if that one lobe wasnt so wide im sure they would work...

i already put my engine back together with my itrs today anyway
