camshafts - weld up vs new billet

[Enchanter]

Do turbo cams fit? If so there's some fairly lumpy HKS jobs available on ebay for $440 US per cam here:

Not being a JZ man I'm not 100% sure if it's the same, but in a 7M the CAS runs off the exhaust cam in the same way the dizzy in a 7MGE does, ergo you can fit cams from either motor in either motor (or fit a dizzy to a GTE if you so desired or vice versa)

I didn't know that about the 7m, I don't think they will swap but I haven't looked either.
I don't like the idea of fitting a turbo cam into a NA engine, I believe they would use different profiles.

Also interested in the weld vs billet argument, um anyone know whether Clive cams does billets for the 7m.

Clive will do cams for pretty much anything, just ring him to see what he can do.

The 2JZ-GTE has a "proper" CAS, ie it's a sensor attached directly to the front of the crank, while the 2JZ-GE uses a dizzy-mounted sensor. This means there are some important differences between GE and GTE cams - namely, the GE cams have a drive gear to run the dizzy but the GTE cams don't. Conversely, the GTE cams have tabs for the "home" sensors while the GE cams don't. This is why he can't use GTE cams if he wants to keep the dizzy.

I agree with JCMF, ditch the dizzy and buy a pair of GTE cams. So much easier and ultimately better.

a pair of HKS 264 1JZ cams went on yahoo auctions for... abotu $650 for the pari

just for reference..

1J/2J cams are rare on yahoo

Well Clive called back and unfortunately he is unable to source any 2jzge billets
He was a little surprised he couldn't find any, he does have gte ones in stock though ....

I think I'll do some more searching before I commit 100% to the gte cams but its looking like about a 95% chance at the moment.

Interested in what welds would be like on a road car to? and prices?

Enchanter, try crower in US they do custom grinds for about 100us more... donno if that would extend as far as non-listed engines but worth a try!

[1jzracing]

I know this is an old thread but i get all my billet cams from NZ,
crowd there has billets for everything! and he can design / match any profile you want

i searched the world for a bmw M20 cam for under $850!!! and he had billets on the shelf for less than half that

my 1j / 2jz cams were like $420nzd each.... thats only about $360aud!!! at the moment and another $40 odd to send over

i think he has 2j atmo ones with the dizzy drive

look them up through international directory, his email is at work will update this later

Frankland Cam Services in PUKEKOHE, (or might be frankland camtech)

[Enchanter]

That will be awesome if they do have the atmo cam.
Crower in the US don't do them but will regind the original for $180 US acording to their response email

[ReQuieM]

Wade quoted me yesterday 1400 or 1300 with a trade order for weld and regrid.

Just a regrind you can get done here for not alot. Its the weld and then regrind that cost alot. Joint down the road said they can do it for around $60 an hour 4-5 odd hours.

Franklin Cams in NZ email:

ps weld ups are dodgy at best, iv had them done many years ago and didnt last

for regrinds on engines like the 2j 3sg etc you generally cant get a big enough profile on them to make it worth while, the base circle gets too small.

you have to get custom shims too which will be fat and heavy making it likely they will jump off the bucket if you rev it up too much

indeed i too am interesting in atmo 2jz cams that utilize the stock dizzy. My only concern about running turbo cams is that they wont run as much duration as i'd probably like due to the intended turbo usage.

[ReQuieM]

Thanx for that 1jracing. I've sent them some mail...

[RONA]

Email sent as well, NZ dollar also very attractive at the moment woot.

Let me know what the response on billets is Rona, I may be interested as well....

Don't be too worried about the turbo grinds duration, the blank billets are easy to get, infact when I spoke to crow a few weeks ago they had some on the way, its just the lack of the dizzy drive that annoys me.

I have just emailed Franklin cams as well, they will be wondering what has hit them if we all do it
