Looking for more pulling power between 2 and 4k RPMs. Not too bothered about top end.
I'm no mechanic, so just need an idea of which is the best aftermarket cam for the job.

Thanks

Nick

Hey ho

     That helps........

     To drop the hp and torque peaks to where you want your power it would be ideal to get a cam with 180-190 duration and a lift in the area of .375-.395".

     I saw a little tractor with a Zuk in it and it had a cam with roughly those specs installed and it pulled like a little monster.......but the power drops off over 4500-5000rpm (shorter duration).
     Check around to see if you can get one reground in the UK, alternatively check to cam manufacturers websites and find the specs on what they are offering.

Hope the opinions help

I think Kent can do a grind for an 8V, I've only ever had one cam from Kent though and it wasn't very good.  I would get it flowed first and then choose the cam, if you get it flowed by someone with a flow bench they will be able to tell you what lift you need (the better the flow the more lift you need). To some extent you will have to do a trade between duration and lift to maintain a sensible valve acceleration rate. IIRC there's a place near you that does custom grinds (Newman cams?). I would ensure that the cam is either ground from billet or built up and then ground back, a straight regrind can do horrible things to rocker angles.

This is my specialty.
Since you are in the UK, its not really feasable for you to buy from me, and there is no way I can compete with Hawks pricing. On the other hand, I specialize, and they retail.
Stock duration on the 1.3 8V cams is 192 with .330" lift. 1.6 cams are 202 duration, and .356" lift.
You don't want to drop any in the duration. Its already a little too low. Keep lift at, or below .400", and you will be fine. A reground cam is fine for your application. Don't waste money on having one welded. Its costly, and unnecessary. Several stock aplications have a profile that should be pretty close to what you are looking for.
Stock 260 Z lobes are 205 duration, and .280" lobe lift. It would give you about a .375" gross  lift. Mitsu 2.9/2.4/2.6 are in and around these numbers as well. Most good sized automotive machine shops should have these masters. Just tell them what you are trying to do, and they should be able to take care of it.

Superfly, if you don't need to weld then thats good. How are you measuring duration? Do you have any timing figures?

i bought a cal-mini cam and header for my '90 8v tracker. it runs great. about the same power as stock off idle. (not much), but once it gets over 2,000 RPM, it is strong and starts dropping off around 4,500 RPM. I have run it up to almost 6,000 RPM. I rebuilt it, and after breaking it in, I ran it hard a couple of times. I figured if it was gonna blow, I'd do it now.

No cat. Crappy OEM size exhaust which I am about to throw in the trash.

A custom grind can sounds nice.... I still have my OEM cam on the shelf.

Welding up the lobes is only required for extremely radical profiles, in this application. Something we will likely never need.
I degree everyone of my cams, and new grinds in a head, on the bench with a degree wheel.
What kind of numbers are you looking for?

I was looking for opening/closing times and the lift at which they were measured. The only figures I found for an 8V Zuk were from Kent for a Spanish 1.3.

Sorry, that doesn't cut and paste very well, original is here:

 US sites only seem to quote duration and lift which doesn't give the whole story. I like to see what the overlap is too. I have found that it can make a significant diffrence if one cam is quoted at 0.5mm lift and another at 1mm, the Kent is quoted at 0.25mm which is quite a small clearance.


Edit: I forgot, I also found this, which gives the timing for a stock Jap 1.3:

I have an 88 Samurai. I've found three places that seem to sell cams, but no one bothers to publish the lift/duration/overlap  :'(

I use my Sami as a "summer vehicle". More of a daily driver, with light duty offroading. So, I want a cam that's going to be mostly responsive in the mid-range / daily driving conditions.


Anyone have any experience with these cams? Anyone pass cali emmissions with one of these? I am not really into doing a custom grind 'cause I don't know enough about cams for something like that

Anyone running one of the above cams in a 1.3l???
