going to be a wuss with this one, will just do some common wear repairs, leave it stock internally

Do the cams wear much?

I heard the pistons are better in terms of weight and friction, how far would it push the CR? i wouldnt want to go for a thinner HG.

Right now as im looking for a tinker project its looking like if the messing with parts will yield a big enough gain it will get:

whatever cheap (i.e. non aftermarket) rods + pistons, whichever is the bomb

Light on rebuild (checking of clearances and replacement of thrust bearing

Single row timing chain

Cams maybe.


But if all that will give incredibly little gain, will likely just inspect timing gear, check the thrust bearing, put in new seals and maybe replace some timing components. And ill do the rest of the good upgrades.

Yeah the rest of my e30 came from a turbo 323 (cept i have redone the spring/shock package and have the 1.4 diff) so the rest of the car is pretty right.

If i go the rebuild path, have you guys heard anything about using m52b28 rods and pistons? And is the single row timing chain conversion worth it?

Yeah i think the m42 will be the go, will just need to make an effort to finder a lower KM one and fit the updated timing parts. Will make it easier for fitment in terms of accessories too i assume.

What cams and chip packages are there? i would like to avoid an aftermarket ECU. If there are large gains to be had from larger cams without headwork ill go for it.



Are there any reccomended updated wear items e.g. stronger lifters

Hi All,

Considering a m42 or m44 setup for my M40 e30. I would want to do the equivalent of a m50 manifold on a m52 + S50 cams and chip in terms of effort and bang for buck.

What i want to use the car for is daily driving but also taking it on the twisties so the ability to run high rpms through corners would be really good.

So with M42 vs M44 which is better for sustained higher RPM? I would not want to look at solid lifters. Then again if the m44 has significantly more torque/power down low it wouldn't be as bad but on the last run i was constantly changing between 2nd and 3rd.

another benefit of the m42 is i would  assume i could save myself from having to get the ps pump and AC pump to fit.

Ideally i would not be rebuilding the head/block.


The plan would be:
Replace all significant wear items and gaskets
Cams
Chip
Maybe valve springs
maybe injectors
maybe aftermarket ECU if needed (if m44 is the schiznit)


Please let me know what the  best base and common upgrade paths are for motors with these requirements.

Cheers

Engine + Driveline / stupid question. is there a way to remove fuel injection and go to a carberator?

should do a pushrod conversion while you are at it

Engine + Driveline / M42 single mass VS M20 single mass conversion

bloody hell this is confusing!!! people saying you need the stock spacer, people saying you need a 3mm spacer, people saying just use the 325i TOB you will be fine....


Anyway my question.

325i single mass (assuming its not 323i as its heavy), spacer drilled off the m42 one, 325i single mass clutch kit, could i just use a longer slave? and do any m20 cars have a longer one? or will it work just fine like the nisse bloke said? theres about 6mm difference between the two throw out bearings.

and with the use of the spacer, wouldnt you worry about it not being perfectly flat and putting the flywheel on a slight angle?


**edit**

never mind, i did further research and now have a better understanding of the topic. i will measure the distance from crank face to the top of the pressure plate thingos to see how far out it will be and wether it needs a 323 TOB or not. will also try to avoid spacing the flywheel out.
