gotta get the head off first.......

gotta get one of those fancy elring headgaskets as well, to make this work

i was gonna make some .030 rings, cut .020 grooves, and leave .010 out of the head to clamp... my problem was the headgasket to stick them on. i was looking at a pure copper gasket, or like a SCE titan gasket, but their website doesnt show one for an S52...... but have seen posts of people claiming SCE does make them. i guess ill have to call them.

anyone running the SCE titan S52 built-in wire gaskets??

We recently had SCE Gaskets redesign their Titan and ICS Titan head gaskets for the E36 motors. They feature a one piece copper design with silicone seals around the coolant and oil passages. The ICS titan gasket has integral stainless o-rings that are sandwiched in the fire ring of the gaskets. Pictures and more info on the ICS Titan design can be found here: http://www.scegasketsonline.com/products/ics.html

Currently the ICS Titan gaskets are only available in 85mm for the M50 and M52 bores. We have Titan gaskets in 87mm for S50 and S52 motors. There isn't enough material between the bores for the ICS titan gaskets in 87mm. You can use stainless o-rings in the block with the S50/S52 in conjunction with these gaskets.

Pricing is $250 for the .080" ICS and $230 for the .080" Titan

Pictures can be found on our photobucket page: http://s291.photobucket.com/albums/l...SCE%20gaskets/

Gaskets can also be custom ordered in thicknesses from .040" to .093" with the ICS design and the regular Titan gaskets are available in a slightly larger range of thicknesses. Pricing varies with thickness and quantity.

Donovan and I have the 85mm ICS titan gaskets in our cars. I have a few thousand miles on mine with lots of 600+whp pulls and 800+ dyno runs so far. Donovan made a bunch of 10 second passes and 700+whp dyno pulls. Donovan also o-ringed his block with backup rings. We have seen no issues with coolant system pressurization so far. We haven't tested the 87mm ones yet. I will give a significant "test pilot" discount to the first person to field test one with the new 10mm ARP studs. Email us at sales@maximumpsi.com if you are interested.

Thanks,
Mike

:doh: :kicksdirt: sorry- just read over that.

well, i wonder if the all-copper gasket would like to dance with those stainless rings?

and lots of talk about just using a stock headgasket with orings/rings as well

man, of all the engines i have built, the stock BMW headgasket sure is the nicest thing i have found when it comes to sealing. (besides boosting- you know what i mean )

[djborya]

I use stock head gaskets.For me they work well even at 40+psi of boost.no problem with stock gaskets and boost here.

[bigugly]

*just* stock head gaskets? no modding or rings/wire/magic?

im tickling 30, and dont wanna have to A) dump money into this headgasket issue again B) want to solve it CORRECTLY and ONCE C) yank the head again lol

Where can these be had without buying the whole top end kit? Not having any luck.

Not sure dude. I'm running a mls currently no o-rings 8 k miles.

[biglou911]

Look at auto parts warehouse . I have different store were I'm buying my stuff but the don't do shipping

[bigugly]

why not just buy a factory gasket?? they seal coolant fantastic...... ill see how the orings work on it

Guess I should have been more specific. A gasket for an m52 is what I'm looking for.

[biglou911]

Now what I wanna know is, with the Oring tool can we make the groves for the o ring in the head? Would this tool work for it ??

[bigugly]

for the head- you should use a bridgeport.


reason people do it in the block, is not because that tool does a good job, but because no real special equipment (besides the cutter) is needed. the cylinders space it accordingly. im doing my head, that way i dont have to pull my block (my machinist said he would disown me if i used that isky tool lol)

Any idea the machining cost to do the orings in the head?

[biglou911]

so there is no way we can use the tool to do the head with it ?

[tciambotti1]

No. Look at some of the writeups and you will see why. The tool uses the cylinder to guide the cutter.

after some research, I don't believe elring makes an 85mm Hg for the M50/52 guys.
