Re: Benefits of Motronic 1.1 to 1.3 upgrade

"I had the 1.1 with single sensor on the tooothed crankshaft.

Re: Benefits of Motronic 1.1 to 1.3 upgrade

Motronic 1.1 did not use the two bellhousing sensors at least that what I thought? Motronic 1.0 used the bellhousing sesnors. I though the main difference between motronic 1.1 and 1.3 as the orginial post was fault finding.

Re: m20 boosting

The TD04 HL 16T is the one I worked would be suitable for a 2.7i M20. It would be even more suitable on M20 2.5 I did the sums ust to see. Some of the TD05 series would also be suitable.. You could run up to ~13 psi of boost without getting to near the choke line. You should be fair way from the sur...

Well if no water is being used the white smoke won't be steam so why would this be a head gasket.

If it running rich check the CTS. They cause this problem.

Yes skim the block by 0.5mm, then your CR will with low CR pistons will 9.856:1 as posted or if you use early pistons you will get 10.92:1 for which high octane fuel will be must along with a RR mapped chip or standalone management. You will get the best from an upgraded cam with a block skim.

Re: standard exhaust manifold

So if the the one piece manifold is split in that not all pipes are linked as I thought, would the two piece be that much better inside. Why not save up and fit a 6 branch manifold. It not like the E34 525i (M20) has any more power than the 325i from the same year.

Re: e30 316 and 318i piston differences?

Both the 316i and 318i have the same capasity of 1766cc. If the bore and stroke are the case this has to be true. The pistons appear to be the same as you indicated.

Be careful about removing material from the head as remove it from the wrong place and you could end up provoking detonation.

The throttle switch in the TPS is "on" at a certain throttle angle, that control the switch over to WOT maps, so even if the change the "indexing of map addresses" would that really make any difference. Surely it would be a whole lot eaiser to disable the WOT function all together.
