V8 Cam shaft

<< < (2/2)

Range Rover Blues:
If you have a sports exhaust and decent filter you have gone about as far as the standard 14CUX can go, if you want a naughty cam then you'll need to get saving for a chip to go with it.

The piper one has good reviews although there are others avaialble, best to pick a cam and chip together (also possibly a bigger MAF meter) even if you fit them as money allows.

Of course a NEW stock cam will make some difference, as will just replacing the timing chain with one that's not now stretched, poor fuel economy is, I'm told, the first sign of a worn cam (or stretched chain).


Now if you are megasquirting, well that opens up a whole load of possibilities.  For a start use the P38 MAF, it's way bigger.  Also swap the injectors for Bosch pintle types, they respond to over-pressuring the fuel which the Lucas disk-types do not.  Also fit a large-capacity fuel regulator in place of the stock one.

Thank you Range rover blues ,I was hopeing to hear from you I e-mailed Turners yesterday and they suggested a H180 cam ,which I
 will probably order next week with followers chain and wheels, I have a megasquirt system which I need to assemble and fit, its complete with the coil packs and mini dizi  but it frightens the living day light out of me.

P S Is it worth changeing the rockers and shaft at 122000 miles.

tack43:
You'll be taking them off anyway to do the cam so have a look. Any sign of wear on the shafts - you proberly won't notice any on the rockers - then change the lot. It may be an idea to upgrade to solid steel rockers - the steel pads can sometimes fall off the alloy rockers!
I would be interested to know how you get on with the megasquirt.

Hope this helps and good luck with the mods.

denzil:
Thank you tack I may strip the engine first then collect the new cam from Turners take all the bits with me  and let them have a look they should be able to tell me what is worn. As for the megasquirt its in a box waiting to be assembled I keep looking at it but for some reason it frightens the living daylights out of me .But when work gets a bit quieter I'll sort the [!Expletive Deleted!] out.

Range Rover Blues:
If you strip then engine then a new set of rockers might be a good idea, as would new shell bearings.  Any bearing parts in fact!

If the crank is ok and the liners reasonably good it should be good for many years.  Some engine rebuilders recomend replacing the rockers because they harbour metal contamination from previous engine wear, so all your new parts have a limited life.
