Hi all
I got the money together for a new cam and gas flow job on the spare cylinder head I've got

I'm looking for low and mid range power

what camshaft do people recommend?

Thanks

Nick

8 Valve or 16 Valve ?

Any cam is an improvement,
Hawks has a 16V cam that
should work well for you.

Aw c'mon Wild I expect more from you like..........TURBO it.

 

At least he could show us how to grind the back side of the cam with a 4" black and decker grinder 

I have a smog legal 8V cam, had it
custom ground before performance
parts were available, noticeable
improvment over stock.  Cost me 4
hours drive and $200, but I'll get
you a custom ground cam for $30,
I'll use my 4" angle grinder

What lift and duration? 

What lift and duration?

Lots of both 

D'oh should have said

92 Vitara 8 valve single point injection

I'm in the UK, was thinking of the Calmini cam, but if there's a better one out there....

No One got any opinions on this then?

Things to watch on cam selection (In my opinion)

RULE OF THUMB

Where do you want your power?

The stock cam (by memory) in your engine is 200 degrees duration and .350" lift

If you want more power up higher then you will need more duration...ie: 220 degrees

If you want more power down lower then you need less duration...ie: 180-190 degrees

More lift is a gain but lots of lift can be tough on the valve train (found out the hard way)
I would not exceed .395"

As a rule of thumb there are always exceptions but over the years I have found it to be 90% correct. (My experience).

Post more detailed engine specs (got a header or other mods?) with where you want your power and the kind of gains you are looking for and maybe myself or others can be more exact.

I had a cam from calmini...

It was to long....

Took it back to them and the ground off the difference on the gear...

After that everything matched up....


But the engine ended up dieing a few months later...


Im not sure if the cam did ir or not...but I bent a rod....

Got an engine from asianauto....with his custom cam, seems a bit more perky....

(still going to swap in a 16v though)

Engine is stock - I run a K & N flat panel filter, and I have a 4 bracnh manifold (think you call them headers).
I have 5.83 R & Ps, otherwise stock transmission, and with 33" Goodyear MTRs the gearing is back to stock (checked on GPS).
It's just about liveable with, both on and of road. But in the summer when I want to tow my folding camper it will be a PITA.

I reckon I have a choice - either sammy t case swap, or get more power from the motor. A friend has just done the t case swap, he has gone back to stock R & Ps, he runs 32" tyres and is running at 4k rpm at 60. So if I do the same swap I would also have to go back to standard R & Ps... trouble is I have a shoulder injury so would have to pay someone to do all of the above.

Other option - find more power form the motor. I have a spare cylinder head, that's in better condition than the one on the truck at the moment, and have found a cylinder head specialist near home, so I thought if I can get more torque between 2 and 4k RPMs that will help when lugging the camper.
I reckon a cam tuned for more torque and gas flow job would do the trick?

Yoak thanks for the info on the calmini cam, think I will drop Hawk a line...

Cheers

do the trany case swap and ill treid you r&ps. mine a little cash for yours.

Hello again

     All the info you gave was great, missing one thing though!

Where do you want your power.

Think of the cam sorta like the engines brain, it tells the rest of the engine at what rpm the peak hp and torque are going to occur.

So YOU really need to get a handle on where you want your power increase to be.

Let me know and I will see if there is something I know of to help you out.
