Just kidding mate, Wiz0r off E21.net. I'm fitting the same engine/motronic to my awesome baur, after I finish my M50. My dad's stripped 325i E30 track car is rapid so I have high hopes for something naturally lighter and stripped as wellmurran wrote:its the best engine for what it gets used for. im not power mad, needing more power than can be used! bar the fitted of the bonnet pins its finished (will post up pics and vid later) been for a drive in it last night, it goes like sh1t off a shovel, loosing traction in 2nd just by flooring it (no clutch kick) and does 3rd gear burnouts! doesnt need more power than the 325i engine has!![]()
There's a fair amount more work in an M50 conversion. Custom engine mounts or subframe is the main concern compared to E30 conversions. But the exhaust/steering rack clashes like an E30, but in a totally, possibly more difficult way. Then there's the issue with the speedo, due to the drive off the gearbox opposed to off the diff like E30s. E21s can forgo a speedo and use M50/M42/M40 boxes that line up perfectly, or use an M20 box at an angle. This causes problems with the gear linkage and the transmission mounts. This is also the same for and E30, and I would of installed an M42 box long ago on my M50 conversion in my E21 but I wanted to keep the speedo drive. Exhaust is another issue, I'll be custom making mine since E21 323i pipes are tiny. I may have problems with the diff on my E21, since they aren't rated very highly, but I'll have to wait and see for that.casper8r wrote:M20 should be great in E21! How much work was required to put that in?
If you're going the whole way why not m50? Shouldn't be that much harder, should it? I suppose if you had a spare m20 lying around it made more sense, but with m50 it should absolutely fly!
Exactly the same mounts as the E30 325i mounts. As I just had to change my E30's and GSF or ECP diddn't have enough in stock so spare original E21 from the Race car it was.town325i wrote:i have a spare set of engine mounts for an e21 m20 engne if any one want to buy them
i mean the alloy parts they are totaly different and thats what i have from when i had my e21duracel79 wrote:Exactly the same mounts as the E30 325i mounts.
