WTB: High Lift Cams

Hi Guys,

I'm looking for a set of higher lift cams. Can be Tomei/Aspect/Datstrat or whatever...

Do let me know if you are letting go and it's specs.And willing to ship to Singapore.

Thanks

i dont think the tomei,s add much lift (.9mm extra aint it)
an msc member has just had some peugeot Mi16 profiles done (268 deg/10.3mm lift) which is nearly 3mm more lift

Will they fit direct without mods? Is he selling them?

he,s running with a 2nd shim under the bucket i believe keith, mine has both shims underneath, and the bucket lip removed (ie, my cams run directly on the bucket tops, like the CR engines)

Where can I get these cams and shims? Need to customized? Really at a lost here...

the shims are all stock ones keith, the 2nd shim replaces the material that was removed to achieve the correct profile, and try a local re-profiler/cam grinder

Sorry frank, I dun really understand the part about "2nd Shim"... How different is the setup from the stock ones?

you cant really do it your self unless you know 100% what ur doing...if you set you cams with incorrect tdc you'll bend the valves...
take your head down to a engine machinist and talk to them about what frank said. they be able to explain and give you a break down.

Frank aren't datrats and tomei have almost same specs 258?

i dont know mycra, but all of the "from blanks" cams seem to be pretty tame, and i would love to try that race Mi16 profile out :)

oooooo

In a lot of ways the micra engine is cheap enough to learn on in this case. I learnt that way, I had a handbook to go off, and a little common sense and caution. And a spare engine in case you lunch it.




With some after-market / regrind cams, in order to get higher lift from stock / smaller profile, the base circle gets cut back - basically making the cam circle smaller. In order to allow for the difference when the lobe is not pushing the valve open, you need to add an extra shim under the cam bucket..
Frank will take a more detailed pic no doubt and it will be clear as day.. :)

aye :D here,s one i prepared earlier lol, a 1.0 cam next to one of my autosprint 260 deg/10mm lift ones (with 2.5mm of yellow tape wrapped around it)

Are they for sale franks ?? :D
