cam identification

[SCHWARTZ]

i have a cam here for the b18ft how do i find out what cam it is?:scratch:
heres what i have found so far
6/9(depending what way up) 11(diamond opposite) 12(166 or 188 opposite) any ideas?
I havnt removed the pulley yet do i need to to find some more markings?

[SCHWARTZ]

Removed pulley and no more markings.

Ask haz best bet.

I'm swapping mine this weekend with a EP cam. I'll get some pics of it for you to compare ;)

[SCHWARTZ]

Are you swapping standard for an ep cam? I had an ep cam but didn't take any info off it:rolleyes: if you could that would be great;)
Even just the the numbers off the cams then I can atleast see if its one of those two cams or not. Cheers matey.

[SCHWARTZ]

well looks like this spare cam i have is standard:cry: now to find the spec of my clio rsi cam and hope its good:sos:

Standard B18 FT Vs B18 EP..... You should be able to make out the info on the cam..

Ep is the top cam.

[SCHWARTZ]

That's very helpfull matey top work. You can see the difference in lift the ep is a good cam you will notice the difference over the std cam.

[Nick k]

I've fitted the inlet manifold too with the bigger throttle body. Bit of a mess about with the throttle position pot as it sits at a different angle but got it sorted :agree:

[SCHWARTZ]

Yep bit of a fiddle but a worthy upgrade. Have you set the tps to click just on opening of the butterfly? This gives you acc enrichment. Unless your using big injectors then prob best to set it past the click.

[Nick k]

yea i have, i'm using 249 cc/min injections in there so not too over the top. Going to get it running as is atm with the standard turbo on then look at changing the turbo to something alittle better ;) Its got the potential but the turbo and management are crap so they will be next for some attention.

[SCHWARTZ]

Are they the Volvo green ones? Yeah standard turbo is way too small and anything over Volvo greens needs a bypass hole then the fueling kinda goes tits up:rolleyes:

[Nick k]

No they are Bosch injector 0280 150 464 ( 249cc 12 ohms ), cant remember what they are from :confused: Greens are 340 cc from memory, standards are 200 cc, Bits of trial and error really and only cost me £23 quid form ebay.

[SCHWARTZ]

Sounds like they will be good for a little more boost without ruining the fueling with a bypass hole. Prob will just need a slight adjustment of the maf.

[Nick k]

They are from a audi 1.8 T :) just remembered, Got the maf set to 650 Ohms

[SCHWARTZ]

Sounds good:niceone:

[Haz]

Try this to identify it. May help.

Maf settings are around 380 for std setup, 650 is usually for std but upped boost although it makes it richer across the board so you may want to leave it lower to start with.

Edit: also I forget whether they should be high/low impedance injectors, but if they are wrong they will blow the ecu outputs, leaving the injectors maxed out and dumping fuel into the bores.

[SCHWARTZ]

very helpful haz Im certain i now have a standard b18ft mk2 cam in the shed and an "e" cam going in the car.:D

[Haz]

No probs. you have the shims too? I've swapped cams in the past and clearances can be acceptable but the e cam wants double checking when timing up, due to lift it doesn't allow to be a tooth out either way like ft's.

[SCHWARTZ]

yeah i have the shims i was going to swap it all over shims and buckets to the corresponding place in the head then check clearances, i will be careful to time it up properly;)

[SCHWARTZ]

ok looks like i have ****ed up and on closer inspection i have the b20f mk2 cam:scratch: im looking for the spec of the cam at the moment but was wondering if anyone has tried this them selves? looks to have the same lift as the e cam but duration and overlap could be different.:rolleyes:

[HAndy]

have you got a dial gauge and a protractor at all?

if so, you could set it up on the head and measure the total lift height, and lobe duration in degrees from fully open to close, and measure against standard cam lobe duration /lift, this will give you a detailed measurement of the grind , to compare against:)

you might have already thought of this , just a thought :ashamed:

[SCHWARTZ]

I did think of this but I don't have any of that gear so would be easier as its a standard cam to find the SPEC of it out, I hope:rolleyes:

i was thinking that, with the williams cams and valver cams .....couldnt find the info anywhere, so in the end i bit the bullet and bought a set of williams cams and did the above, measured all the cam profiles i had for the f7 engine (all 5 different sets ) still might fit the williams exhaust cam next year ;)

That's dedication:laugh:
Yeah I'm not finding much info either bit there's a few places I have still yet to try.

[Nick k]

In regards to the cam timing, I noticed with the EP cam how the error margin reduced. With the cam at tdc and crank at the same you could only move the cam afew teeth and it hit the top of the piston.! Gave it afew good turns once the belt was on :) didn't check the shims though as I'm going for the suck it and see approach :D ( and the follows fell out the EP head when I turned it over doh!!!)

[SCHWARTZ]

its surprising how well the shims stick to the followers and how smoothly the followers move, I have done the same thing:laugh:
I noticed that when i fitted the ep cam also, Im hoping that this b20f cam is even closet to the mark:D

[Haz]

the b20f is the 2ltr es cam. the 2ltr setup, although looks the same, has the combustion chamber in the head and flat pistons so allows for more lift. both e and ep cams wont allow a tooth out, almost one either way but not, if it does, its not that cam.
that link gives a rough idea, but not sure how good the info is, it seems some of the posters are unsure too, so is just a guide. i think i have a spare e cam that i'll check when i get a min.

[SCHWARTZ]

If you could that would be ace.:D I have the cam in at the moment and it runs fine and seems to come in well. I'm thinking of opening up the ports at some point though so if it would make more power I would stick the "e" cam in. I will try and check how far out it can go before it hits.

Dont knw if this has the info about my gtx cam

[SCHWARTZ]

find it hard to see that but think it just shows what the clearances should be, thanks for the effort anyways.:niceone:
