E30, S50B32 321BHP Rightness
Posted: Tue Jun 19, 2012 1:59 am
The E30 was designed to have a straight six, and apparently this is the most popular conversion.
I've been reading lots sourcing bits, learning along the way...
I have gone about my conversion arse about face, buying the diff first, box and prop next, a rear axle from a E36 1.8ti Compact, (yep it'll be five stud eventually) and then the 3.2 Evo engine with Vanos 'issues'.
I'm in no hurry, and hope to get it all together by summer next year.
Progress so far...
E30 M3 Evo SPORT Diff, 3.15/1, i've heard they are rare..
M3 5 Speed E36 Gearbox, bought this as it is the stronger unit than the Six Speed, which has no serviceable parts, and is big £££ from BMW
No spun shells on this unit, new set of big end bearings and a set of ARP conrod bolts to deal with the 7000+ redline.
The S50B32 unit is on the back of my Recovery Truck, put it on a pallet, as the 18ft Aluminium Bed seemed a bit hard.
The next pic is something special, aparently the vanos solenoids like to jump around when advancing the cam timing, this plays havoc with the vanos seals, which are under pressure, from the high oil pressue lubrication system.

Has a solution to that problem..
A couple of 10mm holes are drilled into the Vanos covers, the holes are then tapped, and a couple of grub screws with dry loctite are fitted.
Apparntly, the covers are fitted with the new bolts, then the 10mm grub screws are wound in to the back of the solenoids (even pressue, not to tight)..this then holds the solenoids in place, and prevents vanos seal kit wear..
Will keep you posted on how this works out...
