antrx.com performance camshaft discussion thread
« on: Jun 8, 2003, 06:51PM »

edit: cam prices have been amended due to reasons beyond our control

antrx.com will be offering a camshaft changeover service, where we provide a good 2nd hand cam to be ground, and then, we will send the cam off to you in exchange for your stock cam.

the way this will work is that we ask for a $100 deposit on our cams + the cost of the grind & postage which is $150 for the grind, the plus the postage prices which are listed below..

destinationnormal parcel post (3-5 days)express post (overnite)
melbourne suburbsn/a$10.00
sydney$10.00$19.00
brisbane$12.00$26.00
adelaide$10.00$19.00
perth$19.00$42.00
canberra$10.00$27.00

quotes to other areas can be provided on request

after you get your antrx.com regrind, and once we recieve your stock cam in good re-usable condition, your $100 deposit will be returned. cams that will be used are generally in the 180,000 -> 220,000km age bracket. however, on your request, we can locate a low km camshaft for you at an extra cost.

here is a picture of one of our recently reground ka24e cams... (i applogise for the poor image quality)




these cams are good for a 15kw increase in power. they run well on a stock ecu and stock internals. they are a little bit lumpy on idle, but nothing that lessnes driveability of the car. they also work well on cars with no other modifications, however, the results of installing the cam would be more noticable on a car with other breathing/exhaust mods.

please note, that, these cams are for the ka24e ONLY payment is accepted by direct debit or money order (please pm me for details), no negotiations will be entered into regarding the changeover service. simply put, if you dont provide a deposit, you wont be getting a cam. your deposit will be returned to you once your stock cam has been recieved. you must also pay all postage costs on camshafts too and from melbourne.

you could have them as a special one-off order basis
if someone wants one they can order it but will have to wait for it to be made

so if i send you mine 300,000+ k's on it you wouldn't be getting that reground would you?

How will these go with the teamnse chip no probs?

if not, give us a couple of weeks and i'll most likely get one  ;D

low -> average km cams are preferred. this is because, if the next person to recieve a camshaft only has an engine with 200,000km on it, they wouldnt want to be installing a cam that has racked up 300,000km+

i think that for people with excessivly high km's on their cams will have to purchase another 2nd hand cam for their grind. or, if you can do without your car for a little while, you can remove your cam, send it to melbourne, and have it ground and re-installed in your car.

as stated in my original post, you need to pay for postage for your old cams to melbourne. you would have to pay for these costs in the first place if you were going to have your cam ground in melbourne. i'm running this as a non-profit excercise, and if i were to pay for postage of your old cams to melbourne, i'd be losing that postage cost every time i got a cam done and i'd rack up huge monetary losses over time. therefore, the cost of the cam to you will be as follows:

initial deposit + grind + postage to melbourne + postage back to you. then your initial deposit will be returned.


installation is relatively easy if you are confident with working on motors and you have the nescercary tools. you do not need to remove the head. you only need to remove the rocker cover.

is there anything that happens to cams over time, like do they gradually degrade or anything?  If i take my cam out what do i have to look for, with things going wrong with it... if that makes any sense  :P what i'm tryin to say is what is worng with a 300 000km old cam?

its just because that i'm trying to provide a change over service, so someone that has a car with say 200,000km on it would want to avoid putting in a 300,000km old part, its just a case of general wear and tear in most cases i suppose.

but something to look for would be scoring in the lobes, or even chunks off the edges.

at the moment i havent been able to locate a ca20e cam, so you might have to look at, possibly being without your car for a week or so and sending your cam to melbourne & then getting the same cam back.

the 288 degree one you need to do a shitload of work to run it.. larger injectors, forged pistons, aftermarket ecu, new race prepped lifters, new race con rods.. and all this is only available from nismo (except the injectors & ecu which you can get anywhere). i can get it all, but its not cheap by any means.

however the 270 degree cam can be used on a stock ecu.. mitza is running it now on his mostly stock trx.

Well if it dose work with a stock ca20e engine (R31 version) ill seriously think about it, i have to look into how much effort is involved first & if i have the tools, but once that faq is up i should have a good idea. My cars at 288,000km so you'll probably have to regrind my cam and send her back. At the moment she's off the road so it won't matter if it takes a while.

All up that would be $232... 120 for the grind, 100 deposit, 12 postage (is that the same to ipswich ?) and do you have a preferred payment method ?

If i do decide to go ahead it'll be a while before i can send the cam down, Im still doing general maintenance on the car witch is keeping me poor !! So about a month id say... this week ive got the breaks radiator n plugs, next week's leads.. after that i could save for the cam.

Yes, i did shave the head but you can only safely take 0.2mm off. Which isn't much more compression.

if your sending your own cam down, deposit isnt required. also, you'd probably have to do that anyway, as i think there are only 2 or 3 r31 pintaras here at the moment.

I've been ringing around some wreckers to get quotes on second hand ca20e cams and ive been quoted from place (X) $235 and place (Y) $200

I think ill do some more shopping around for a cam, i don't want to spend double the cost of a cam just for convenience.  Hopefully there will be a bigger degree cam realy for the ca20e by time i have mine  ;D.  Fingers crossed.

Just a quick note, if you are getting a 270 deg cam or higher in an AUTO, you will need a hi-stall converter which is about $800-$1500.

The only problem with hi stall converters is that they generate more heat than stock converters because they work by 'slipping' of turbines and impellers which are componants in the histall which might reduce the life of the auto. A good idea is to fit an external auto trans cooler which is easily done at about $85 bucks, keeping the auto as cool as possible will increase its life.

And then, once that's done, get sssgtr to convert the lifters :)

hey noss are you still offering this service??

i am 99% sure that i will wont to get a reground cam within the next month, if its possible.  how much will postage be to hobart? and are you planning on putting some info up about installing the cam? i wont to install it myself and am fairly confident in doing so, but, some simple instructions and pics if possble would be great.

thanks ;)
jimmy

P.S> when i get the cam id also like to buy an antrx sticker

ziin: its hard to explain a lumpy idle to someone that doesnt know what it is by typing.. maybe te only way i can describe it is kind of like a wrx. if a car has a lumpy idle (normally worked v8's) then you will know, just listen to the engine/exhaust noise.. it doesnt sound smooth like a stock car. but yeah my trx sounds wrx-ish at low->mid revs

jimmy: according to australia post, postage to hobart will be $7.40 normal post and $9.60 express post.

i will have install instuctions/pictures on the forums as soon as i pick up my new head & get my hands on a camera.

if you get the 270 degree cam you must either get the tops of your cam caps machined or buy solid lifters

Solid lifters being the best alternative.  ;D

To be brutally honest, if you don't understand why they need machining and what it will achieve, you shouldn't be looking at doing such a mod yet without doing some research on cams and valvetrains.

Whether you’re building a street performance engine, a killer drag motor or a Winston Cup powerplant, the valvetrain requires special attention if you’re going to maximize reliability and performance. Most stock valvetrain components are only good up to about 5,500 rpm. Beyond that point, upgrades are necessary to handle the higher loads.

Even though the camshaft turns at only half the speed of the crankshaft (one revolution of the cam for every two revolutions of the crank), engine speed reaches a point where the springs can’t pull the valves shut quickly enough to keep the lifters on the cam. Instead of following the lobes back down to the base circle, the lifters begin to kick off their lobes. And the steeper the profile of the lobes, the worse the problem becomes as rpms go up.

When the springs can’t keep up with the cam, the lifters bang back down on the cam and bounce slightly, causing the valves to also bounce as they seat. In addition to increasing wear and the likelihood of fatigue failure, valve bounce also screws up airflow into and out of the combustion chamber and hurts high rpm performance.

If engine speed continues to increase, the point is soon reached where the springs can’t close the valves fast enough before they start to open again. The valves begin to "float" (stay open), which allows compression to blow right past the open valves. The engine begins to misfire, and if the driver doesn’t back off on the throttle he runs the risk of a valve kissing a piston goodbye.

Quote
If you’re installing a new cam, replace the lifters too. Never use worn lifters on a new cam unless you want to wipe out the lobes in short order. Use plenty of assembly lube on the cam lobes to protect them when the engine is first started, and run the engine at 2,000 rpm or more for 20 minutes after the initial start up to break-in the new components. Don’t let the engine idle during this critical break-in period.

Jim Hill of Crane Cams, Daytona Beach, FL, says cam selection is what determines an engine’s power curve and personality. A typical street engine might never see more than 6,200 rpm while a racing engine will usually turn up to 8,000 to 9,000 rpm or higher. So you need to pick a cam and lifter combination that matches the application.

For street engines, hydraulic lifters are usually better than solid or mechanical lifters for several reasons. Hydraulic lifters automatically maintain zero valve lash so they don’t have to be readjusted periodically. They’re also quieter. But for all-out performance, many racers prefer solid or mechanical flat tappet lifters or roller lifters because they can handle higher rpms without pumping up.


New lifters & a set of slightly tuffer springs do a world of good & so dose high lift rockers + cam  ;) pitty im not that adept or id put it all on my car :p but a cam's enough for me.... might get some new lifters though.. old ones truly are on the way out lol

Hope that helps you :)

i'm not driving my car much. i went on a cruise & other than that i might drive 10km a week because i'm waiting for the parts to come in for the solid lifters.. (i had to source a new head as well) if you heard my car's engine, you would understand why i'm trying not to drive it and also why you would need to machine the caps/get solid lifters.

machining the caps would allow for you to pretty much not bothr about anything that goes on in the engine (i.e. no adjustment) so it would be like install & forget.

You'd be looking at no more than $50. But if you can't take them out of the car yourself, you're up for labour from a mechanic.

well yeah it could do some damage. ca20e lifters are adjustable, if you dont havea gregory's manual, get your hands on one, it explains how to adjust them.

Noss is still around, and it's a fair question. So IMO the thread dig is warranted.

I don't believe noss can get cams done any more, but I'd wait for him to confirm that first.

Fair enough but I would have thought there are more recent threads?
