Add a third Manta to the BMW V12 club although mine's going in a B series. I'm glad to see it fits cos everyone I've told wouldn't believe me! Will you be sticking to standard engine management for this?

Transeurope, what box have you fitted? A Getrag 265 is a good fit in the standard tunnel with an adaptor plate and the auto bellhousing. Use a V8 flywheel and cobble up a clutch using M3 bits. Easy!

now i need to build a new gear-tunnel =)

How far do you need to cut the bulkhead?

I'm intending to cut (red lines) the firewall like this (black stripes area will dissapear) and move it in direction of the blackstriped zone, hope this is far back enough?

looks cool, who will tune the ecu? where would you get a standalone harness for these? over here beemer motors are cheap as parts costs are horrendous and no one wants to wire them, i was going to fit an m3 motor but for the wiring issues and to be honest it seems way too much work for only 320 hp! the v12 looks way forward for good handling, what does it weigh?
