[QUOTE="Jipster, post: 70808, member: 97"] For clarification.....the following numbers came off bimmerforums.com : S50 Straight 6 DOHC 24V Solid Lifter Valvetrain with Single VANOS and Individual Throttle Bodies. (Dual Vanos on 3.2Ls) 1992-2000. 152kg 333lbs M50/M50TU Straight 6 DOHC 24V/Straight 6 DOHC 24V with Single VANOS. 1989-1998. 136kg 299lbs 2.0 (150bhp), 2.5 (192bhp), 3.0 (240bhp) Sometimes referred to as S50US I selected the above engine variants based on their popularity as potential 'drop in' conversions for the E30. The data of interest in this context is the weight (unknowns are whether weight is dry weight or wet weight; also what is considered to be part of engine e.g. manifolds etc.). Compare the above with the M30 weight below (from same source) : M30 Straight 6 cylinder SOHC 12V. Big Six. 1973-1993. 143kg 315lbs 2.5i (150bhp), 2.8i (184bhp), 3.0 (185-208bhp), 3.3 (200-206bhp), 3.5 (218bhp) In my opinion the weight difference appears to be minimal and can be managed. What I am trying to say is that the S50/M50 conversions are known quantities here in Malaysia i.e. it has been done before - and I have not heard anything negative from the owners of said cars regarding their weight distribution. I have also read a comment made by a person named Ian in E30ZONE (UK site) who has done an S50B32 conversion on his E30 - he didnt think the extra weight of the S50 affected the handling performance of his E30 very much and apparently he has clocked very impressive times on the track with said conversion. Consider finally the original weight of the car - assuming it is an M20: M20 Straight 6 cylinder SOHC 12V. Baby Six. 1977-1992. 117kg 258lbs Big difference right? I suppose on paper figures may not tell the whole story........ enuff said.... [/QUOTE]
