Subject: Installing E30 M3 gearbox: has anyone done it?

An E30 M3 cr gearbox fell in my lap. I got a '69 cr gearbox, so I don't really need it, but they are supposed to fit rather easily in an 02, even to the extend you can attach the speedo cable (with little modification). Has anyone done this, any pics perhaps. How great was the ordeal? I may keep it as a spare, or use it since they are stronger boxes. No points on originality, but who cares.

I don't know if the CR and Standard gearbox are the same weight but if they are, the E30 box is a lot heavier than the 02 or 320, which is a factor of why people don't do that upgrade.

The only folks who use 265s are, AFAIK, those with S14s. Two things make a 265 install painful: (1) it doesn't really fit in the tunnel, even if your 02 is an automatic. The tunnel needs to be split and additional sheet metal installed -- and (2) the transmission hangers, or 'ears' don't line up with the 265 hanger points. SOP is to bolt the aluminum crossbrace from the M3 that goes under the transmission to the floor of your 02.

The ordeal isn't huge, nor is it hard but there is work involved but it's nice to know i have a bullet proof getrag 260 gear box, with my m20

I'd love to get my hands on a CR/dog led gear box. The moment i do it's going in.

I lost patience when doing this(trying to fit tranny in and out repeatedly) and just cut the whole top area off.
Looking back i could have done a much cleaner job, cut off less and blend the tunnel better where it meets the E-brake.
Keep in mind that the finishing is affected, original carpets(to short), center console(to high), gets pushed up, if tunnel is to high

If i where to do it again i'd keep everything to a minimum, cutting, clearance of tranny and blending the finishing top layer sheet metal cleanly, trying to keep as close to original as possible.

Would i do it again? yes
Only better!

Thanks for the info and pics. I think I'll sell it on. Looks like too much a hassle.

I'd sell it to you but I think with the current dollar/euro ratio and the shipping costs your stomach will turn if I give you a quote. ;)
