modify a camshaft
 

i like to save a buck as much as the next guy but sometimes i get too gehtto, and i tried a search but no deals with that so i apologise if this has been debated before


ive built myself a t3 kit on a 90 integra 11psi, so everything im saying would relate more or less to what ive built

what if you take stock b18a cams and drill and tap holes in the center of the peak of each lobe....thread in a stud with thread lock and have the stud sticking out, round the end and check for peak lift on all lobes with a caliper


turbo cam? O0

haha yeah great ideal, Might want to buy some spare rockers now :-X

Re: modify a camshaft
 

You're better off re-profiling your cams with a file, like the old school machinists used to. It won't be worth your time, even if you work at McDonalds, compared to what one of the regrind companies will do it for... but that's not the point, is it

Re: modify a camshaft
 

ya, i guess it would be quite a bit of work, but the hair on my ass stands up when i think about rockin 300hp on butchered basement cams, i think im gonna try drilling some holes in a extra set of cams i have, and mabe no tapping, just jb weld, i'll do one lobe and see how long that takes, then X16 and i'll see how much beer i have


what do these regrinds usually go for JD?

Re: modify a camshaft
 

That's taking JB to a new level. ---- why even mess with an old set of cams. Just make some new ones completely out of JB weld! 8)

Re: modify a camshaft
 

search around for delta cams... they have great prices on regrinds.

Re: modify a camshaft
 

There is a delta cam by my house. I can give you the Tacoma number if you want it.

Re: modify a camshaft
 

dude go for it... no one ever acomplished anything but haveing some one else do it for them

*leans over and wispers to everyone else* holy ---- hes going to blow something up this is going to be cool...

just kidding man... it will take alot of your time

Re: modify a camshaft
 

that would be great man, the delta website seems to be down

Re: modify a camshaft
 

did you fall in the vate of crack or what man :-X that is got to be the most retard ---- i have ever heard your going to spend more money then you would save which totally defeats the point of the thread

Re: modify a camshaft
 

huh?

the mod or the destruction it would cause?

i would think the mod would be pretty cheap

Re: modify a camshaft
 

haha ;D

i did a quick search on HT and it looks like delta charges between 60-90 bucks per cam, i didn't know it was that cheap, the time it would take measuring and grinding would suck, i think im gonna just pay

but when i do decide to blow my motor (2 complete spares, 4 heads, no problem) i'll be sure to post a link to the vid 8)

Re: modify a camshaft
 

wtf ??? :S :X

Re: modify a camshaft
 

There was two numbers in my book for them 253-572-2474 and 253-383-4152

Re: modify a camshaft
 

are you ------- kidding me? seriously?

Re: modify a camshaft
 

Ahh, the good old days of the "belly grinds"...holdin the cam against your stomach and hittin it to the bench grinder. Takes alot of practice to get that down pat. :P

Re: modify a camshaft
 

cool, thanks :)

Re: modify a camshaft
 

i didnt think it was that crazy, if i really want to prove this will work or wont i can always try it on the cam in my spare car (91 chev sprint 3cyl), 6 lobes on 1 cam then rev the piss out of it, but its a little different in there, the lobes hit the valves directly, no rockers

Re: modify a camshaft
 

You're welcome. They have the best prices that I could find. It will cost me like $80 - $90 for a custom grind of a 59 Corvette solid lifter cam.

Re: modify a camshaft
 

haha no ---- WTF

Re: modify a camshaft
 

Lol holy ---- i guess i have read it all now.Your rockers would probably still last longer then with OBX cams :D

Re: modify a camshaft
 

that will absolutely not work but I would like to see you try

Re: modify a camshaft
 

they ride on the lifters not the valves

Re: modify a camshaft
 

This thread makes my head hurt :S

Later

Re: modify a camshaft
 

I've seen much worse on H-T today in just 2 hours ::)

Re: modify a camshaft
 

I belive the studs will break before anything LOL, then the broken part get stuck somewhere and ---- up even more ----.
I mena if you have a spare engine then it`s worth the try lol.

IMO better off lay a thick welding on top of the lobes then grind it down. Or, cut out the top half of the lobe form a different car then weld it onto ur cam :S

Re: modify a camshaft
 

dumbest ---- I ever heard. :)

Re: modify a camshaft
 

lol, i like the way you think man!
but i didnt realize delta was so cheap

Re: modify a camshaft
 

delta is still money. I say do it. I did it and it works great

Re: modify a camshaft
 

wha..........what :-X

Re: modify a camshaft
 

fiesable hypothetical thinking is where new ideas come from

props to anyone with that capacity

Re: modify a camshaft
 

i vote weld and grind

Re: modify a camshaft
 

The next step is determining practicality, critical before making a post. Also a valued capacity.

Re: modify a camshaft
 

Time vs money - the answer is as obvious as it is individual.

Re: modify a camshaft
 

---- done right thats around 400 per cam

Re: modify a camshaft
 

I've spoken to machinists who've seen two welded crankshafts that they liked in their lives. That's not a cam, but it gives you an idea of what to expect going that route if you don't find the best welder possible and make a point of not asking how much it costs before you decide who's doing the work.

Re: modify a camshaft
 

I'd love to see someone attempt to drill and tap an m4 bolt into an oem camshaft.

Re: modify a camshaft
 

I see what your trying to accomplish here... but your asking for a lot of headache. Tell me... how do you plan to drill the hole perfectly center, perfectly straight, on a rounded surface? Because each lobe would have to be precise. Not only that, but you have no way to accurately check each lobe. Yes you can use a caliper to check the highest points, but only the highest points. Your valves may open the same amount at the peaks, but one may stay open longer than the rest depending on duration. JB Weld is a bad idea, it wont hold, especially once it heats up. Threads would probably hold for a while, but not for a long time. The stress would cause them to get stretched. Even with Loc Tite the bolts would eventually work there way loose.

Another thing... cams are hardened steel. Good luck drilling and making clean threads. I work in a steel manufacturing plant. Hardened steel is not something that can be easily cut or drilled into.

Re: modify a camshaft
 

just do it to a set of ching chong meow cams that usually snap
