So I've heard that E36 lifters will drop right into the M42. If that's correct then there are VW solid lifters that would work also.

That's a link to someone selling the VW lifters I think.

Any thoughts? My M42 will be turbo'd and used in club racing in my E30 clubracer.

At 59 grams plus the weight of the shim they are heavy. If you are planing on spinning your engine to beyond 9k then the shims will get kicked out as well. If you are trying to save weight then get the hydro lifters from four seasons racing which weigh like 48 grams and even with the oil will be less than than lifter and you dont need a different cam profile.

so has anyone actaully used the VW lifters?

What would be a good source for aggresive cams and solid lifters for the M42?

bump

dino do you have any more info on the vw lifters? has anyone tried them? is the oil passage at the same level?

I have not as of yet used them but I will be using them for my motor. As for the oil passage the oil supply goes into the lifter through a ring around the lifter so no mater where the lifter is in the bore it will get oil. Remember the lifter is going up and down as oil is trying to get in it. There should be no problem.

That isn't how it works. The oil galley feeds the lifter pressure to keep preload on the cam while on the low side of the lobe. As it rolls onto the lobe the galley on the lifter is seperated from the galley in the head blocking the oil into the lifter. Since oil doesn't compress the valve opens instead of squishing the lifter.

In other words... oil galley height matters. I have a bunch of VW lifters here. I do mean a BUNCH. If someone wants to measure an M42 lifter (with pics so we're measuring the same stuff) I can do a VW lifter.

overall height 1.021"
OD 1.376"
height from bottom of lifter to bottom of passage groove .380"
from bottom of lifter to bottom of oil hole .422"
groove width .084"
oil hole diameter .097"

Anything else needed? I can get more accurate measurements when I go back to work on tuesday. All I have at home is a crappy old dial caliper

Grrr.. Just spent about � an hour writing a reply, just to have explorer crash.. How come it never crashes when i'm just browsing websites with nothing invested!!!!

I dont feel like rewriting the response, but to be just a bit productive..

Study this image from the Schrick Catalog.

As resume of what i wrote:

Shim-on-top: Waste of time on M42, You need to disassemble almost all the valvetrain to adjust anyway. Due to design of engine.

Shim-Under: Only go (Opinion), as you need to disassemble pretty much all the valvetrain anyway, you might as well go with the best solution. It's often the most expensive setup though. But theres nothing mystical about it

Possible suppliers: Schrick, Catcams, Motorsport.. Etc.

Metric mechanic made spacers like the schrick i just provided partnumbers for. Only difference being that the MM version accepts small adjusting pads from the E46 engine. (My reasoning from the images of the catalog)

The schrick spacers are ~8€ a piece. So you end up with a pretty cheap setup!! But perhaps a bit heavier than the dedicated lifters. But you have to decide when enough is enough.

I chose some lightweight dedicated from Catcams, which is a good product. But i suppose with deeper pockets i could have found even lighter lifters. But is that really needed on a stret engine ??

Also, I have to ask as i simply have very little knowledge of the consepts and application of forced induction.. Aren't it unusual to have very high reving FI-engines ? Dont they almost always operate in a relatively low RPM range.?? So won't you be okay with Hydraulic lifters?? If this is the case i would recomend against changing over, and just use the stock lifters and get on with the project :-)

The depth of the plunger from the bottom of the lifter would be good to know. Eyeballing it says ~.280"

Everything I've compared so far is exactly the same.

A VW 034 109 309AD weighs 64 grams both in new in baggie form and used out of an engine. There are 'lightweight' versions. The part number slips my mind but I'm sure I'll figure it out tomorrow. I also heard of someone using some out of a Volvo engine that were supposed to be lighter. A quick search on Ebay found some shim-under bucket solid lifter conversion lifters for VWs that would work in an M42.

shouldnt it be measured from the top though since thats what the lifter rests on
