i would have thort it would be better to go for solid lifters, then you can run a much more wild cam.

Solid lifter for teh win! BUT, they cost 43� / piece at Dbilas, that is 688� for 16 valves!

:eek:

Another thing to consider is that Metric Mechanics state that stock OEM hydro lifters are ok up to 8000 RPM. That is the upper limit where I'm going to try rev the engine in any case. I am not very hopeful about stock bottom end holding up way past that... So in my case hydros are enough, no need to spend money on solids

Just started to tear down the head I received, so far so good. No signs of damage yet and valve seats and valve stems seems to be in good nick, yay!

I have to buy accurate scale for measuring masses of small valvetrain parts...

MK1 golfs have them and they fit bmw engines, i think older audis also have them, i'm on the look out now for some

kent and piper cams told me that with hyrdo lifters (which i was planing to keep) i could only have an off the shelf cam, maybe 12-18bhp gain, but with solids i can have what ever duration what ever lift ect ect and gain alot more bhp

Call Web camshafts in California, the will grind a hydro lifter to any grind you want. Dont waste your time with "off the self" my 2 cents

E30 intake manifold will not fit E36, the angle of engine seems to be different so the manifold will be higher and will stop hood from closing...

is this true? want to use the E30 intake on the e36.

The m43 intake was the same angel as the e30.:confused:

I think that is true, hydro lifters do limit the duration of cams. Again there is one BUT in my case

I cannot use wild cams anyway because car must pass emission tests. I think regrinds can go up to 260-270 degrees which SHOULD be easy to keep street legal... There is not much reliable data out there regarding emissions and cams

Anyone know more about the VW solid lifters? Weight & part number would be nice

Head is now taken to pieces, so far so good. All exhaust valves and seasts show some degree of pitting on sealing surfaces but no obvious leaks. One exhaust valve has small hole about size of tip of a needle on outer edge of valve. It does not allow leak fom cylinder to port (yet) but I think it must be replaced.

Seems like my intake seats have been cut to 2 angles, 45 and something else. Can anyone confirm if this is done fom factory?

Also installed 12 v 17 Ah bike battery (battery 6,1 kg + DIY bracket 0,9 kg) to car today, weight saving over stock (which was 17,1 kg) 10,1 kg. Bit dissapointed about that, I was expecting more.

This is what I have read from internet (so your mileage may vary...) and also heard firsthand from fellow E36 318is owner who tried the swap and said the hood would not close. Also, I have never heard from anyone who has completed the swap. But only way to be 100% sure is to try it out I guess.

How about using only the lower part of E30 intake manifold and constructing your own intake plenum that will surely fit?

Just add box (CF, fiberglass, aluminum) with holes for throttle body and intake runners. You might also need to build extensions for intake runners if you want to have any low end torque

Not much has happened lately... Cleaned the head and took some measurements so I can plan port/valve/valve seat modifications

Does anyone know if E30 double springs are straight fit to single spring E36 head? I would think valve pockets needs to be changed as well as spring plates?

I think I will order few sample E30 parts to see if I can get them to fit E36 head, not a large investment.

Ooops! Just bought cheap E36 M3 S50B30 ITB's and injectors + rail from ebay. I made a small just for kicks bid and it won :eek:

I try to get E36 M3 airbox too, seems like it is possible to chop off one runner out of each end and then weld them shut. No idea if it will fit under the bonnet with M42...

At this point I'm not sure if the E30 intake will fit with e36 hood.

Check this from Ludiagsm turbo thread:

And I have a picture of another car with it and it's fitted... the only thing is that they doesn't have the insulator thing ounder the hood.
I really want to know if the e30 intake will fit on e36 with oem hood
bye.

Hmmmm it sure is E30 intake on E36! :eek:

Ludi must know for sure at this point then. Did he need to modify the hood? If you remove insulation and the strenghtening structure inside you could gain maybe 2-4 cm extra clearance and that might be enough.

Or you could buy glassfiber hood and then easily put a small power bulge on it just like in E46 and E92 M3's

Had an interesting chat today with fellow 318is Class II owner at local racetrack. He had just talked with race team that runs M42 on Ford Escort

They had used the engine on E30 318is endurance car before, that class has quite strict rules for modifications to keep the costs down. Camshaft was OEM reground to 267 degrees, OEM hydro lifters, OEM air meter etc and rev limiter (custom chip on stock ECU I think) was around 7300 if I recall correctly. Head was ported. Stock vibration damper. Power at the dyno was slightly over 190 hp.

Later on current Escort form, the engine has more agressive cams, around 35 mm intake valves (stock 33 mm), stock crankshaft and conrods with Wiseco pistons, 12+ compression ratio. ITB's I think. OEM hydro's modified to solids, adjustment by small pieces cut from valve stem. Rev limiter 9000 and power bit over 210 hp :eek:

I think I try to contact the race team, maybe they can give full list of modifications if I ask very nicely

yeah try and find out more please, oooww 9000rpm sounds fun
