m42 schrick or bilas

Post Fri Mar 10, 2006 9:02 pm

Hi all,

Can anybody inform me of gains in hp as a result of using either Schirk or Bilas cams? And what extra needs to be done to make this setup work. Have on optio of a set which gives 10.7 lift where std is 10.2. Also I guess I should change springs to compensate for the exrta lift/force?

Im going to rebuilt my engine and I was thinkin bout changing the cams for a beefier pair, but there is many choise out there....and since cams are new to me, my mechanical skills comes from restoring 2-stroke yamaha race bikes, i really could use feedback.

I found Bilas,Schrick, ACschnitzer and Kent cams. The ACschnitzers lists 150hp, but dunno if they are still for sale...
Bilas and Schrick have many different cam profiles..but no hp listings

I dont want a "only works on the track" engine, but gaining about 15-20 hp would be welkom. I dont mind changing camsprings either.

Hmm, you dont believe this.....has anybody in the states ever heared of JRP JOHNSTON RESEARCH & PERFORMANCE INC,,GLEN BURNIE (MARYLAND) ??

They are distributer of a company called CatCams, which is based in Belgium, right around the corner from where I live! However none of them state any Hp gains when switching to different cams.
Can anybody see and explain the different in cam profile if I paste the specs of the Catcam in here?

Hi

I have looked at cat cams for my m42, putting hp to any perforamce component is BS as far as i am concerned as these things are rarely done in isolation.

I have spoken to cat cams, decent guys, they speak engilsh okay, see what they reckomend.

A lot of s14 guys rate there cams

Yeas ill give em a call this week and see what they recommend and ill post it here.
The new cam will go together with chip,exhaust heater, lightent flywheel,air-filter and airshield. Was also thinking about insulating the enire air-intake section to cool intake air down (or actually prevent heating up)...
Anyhow ill keep this topic updated

you considered regrinds?

Post Tue Apr 04, 2006 7:42 pm

I think the milder CatCams are regrinds whilst those higher spec than is atainable from the originals, are machined from a blank (hence are more expensive)

Don't quote me, like.

PS I think Poven Products are the UK dealers for CatCams

Also: You can use the solid lifters and shims from an S50, and quite possibly the valve springs. Perfect partners for higher spec cams and would help allow you to rev a lot higher..

Sorry dude, I can't be more specific. I'd just started finding out details about M42 tuning (I have a 318is) but thought 'sod it' and went and got an s50b32 instead of getting oily.

Shameful.

Perhaps I'll keep the M42 engine for a garden shed development. That way I can pretend I'm still an engineer and not a cheque book beemer driver...

If you find anything out, post it up.. I'm still interested!

lol. will do, basically i'm sure they'll either fit.... or won't. i want to get hold of a s50b30 valve and vlave gear and have a go at some pt, but have enough projects on the go at the mo! i have a spare head to play with when i find some time and get the parts though.

Quality engineered parts is UK catcams dealer, they cut them all from blank and dont want your old cam, for Ã‚£190, and they said they would do custom spec cam aswell for the same price just tell them about your engine.

Wow, too funny. I join E30zone to poke around for M42 information... Glen Burnie, Maryland is 15 minutes from me.

190 for catcams for an m42 engine???

Post Mon Oct 30, 2006 10:23 pm

Will G you go a phone number or a link to this quality engineered parts.

Ãƒ”šÃ‚£190 is well cheap for blanks i found Ãƒ”šÃ‚£232 for regrinds to 280/280 but only if it was running MS or piggyback
