Group buy on Crower cams for 1jz Wed, 16 November 2005 02:37 Go to next message
Posting this for anyone interested in upgrading cams for their 1jz-gte non vvti.

http://www.supraforums.com/forum/showthread.php?t= 315120&page=1&pp=50

Go to the link to see what is available. I am getting 272/272 with 9.1mm lift and not upgrading springs and retainers.

This is not a for sale ad but we need 20 people to get REALLY good prices on these cams. The price is between $475US and $500US plus postage. So about $660AU plus postage. I am still getting postage quotes but as you can see that is cheap. That is for the set BTW.

E.g I got quoted $1250 for reground stock cams from Tighe.

PM Zazzn on SF.com as he is organising it.

** Ok ** It seems like there is lots of intrest

So who is REALLY willing to go for cams.

Is anyone intrested in crowler retainers and springs?

yeah, my gains I think will be a bit different to typical gains Razz

I would think a fair amount but can't really guess a number. The basics are that most people can make close to 300rwkw through an auto with stock cams and a decent single turbo setup. If you want much more than that, it is a good idea to upgrade the cams and valve train to allow more air at higher revs and also be able to rev the engine higher which will also allow it to make more power.

I can't remember where I found it, but there is a graph of different cams for the 2jz. It is for HKS ones but you get the idea, has stock cams, 256's, 264's and 272's. The 256's and 264's seems to bring the power on a bit quicker and make more power in the top end whereas the 272's had similar low down power to stock cams but more top end than all other cam setups. This is HKS ones which are 9.0mm lift for 256 and 264 and 9.3mm and 9.0mm for 272's (exh and inl) are different. The ones I am looking at are the 272's with 9.1mm lift or possibly the 268/276 9.5mm and 10mm lift as I am now thinking of getting the valve springs and retainers as well and may as well go all out Smile

Going to ask Manny about interference on the 1jz engine now.

He said that HKS/JUN say that anything above 9.0mm becomes an interferance engine. Snapped a timing belt with 9.0 264's and no bent valves.

So any of these options make the engine interference.

Have you spoken to Wade cam's in Victoria?
Wade ground me up a brand new set cams for billet castings they do and they cost me in AUD what you are looking to pay in USD.

Clive Cams here in Vic is able to get billets for the 2JZGTE so you might wish to investigate if they are the same as 1JZGTE cams. Last time I chatted to Clive (two years ago), he was quoting $700 + GST for the pair.

CLIVE CAMS
31a Metropolitan Ave Nunawading 3131 (03) 9877 3607

Michael, don't know what other billets he is able to get.

Also try Kelford Cams in NZ. Tighe and Wade have already been mentioned.

So are new billet ones cheaper than adding metal and regrinding stock ones? I got quoted $1250 for regrinds which I thought was pretty damn steep considering the price of second hand HKS cams.

I may give these guys a call and see what they can do.

2jz cams need to be modded to fit in a 1jz. Crower are getting someones stock cams and making them exactly the same but with more aggressive lift and duration but it will be bolt in, no modding bizzo.

Just rang CLive Cams.

This is my notes from phone call.

Clive Cams: $750+GST for 2. $825
Checking for Stage 1 crower grinds
Doesn't have that same cam. (Stage 1 Stage 1 i214 0.380
264 e218 0.380)

Can get .317 lift 219deg at .050
Used to do the GTRs at Bathurst
Bugger all diff in performance by changing lift in the GTRs.
Duration makes more difference to hp.
Use cam gears and separate the cams to reduce overlap.



Gibson GTRs use 250deg@.050 with wide lobe centre line.


That seems to be quite different to what Crower said about duration and lift. These cams are 8.0mm lift and 219deg duration so to me that seems like a HKS 256 as it has slightly less duration than the HKS 264 but the HKS 256 has 9.0mm lift whereas these are 8.0mm. Opinions?

Unsure. I read it on SF.com. A guy fitted stock 2j cams into his 1j to see if there was any difference in power. (negligible) He said that some part of it had to be ground back or something like that. I don't really know the specifics.

Spoke to Tighe and they were trying to sell the regrinds rather than new ones and they are $1200ish.
