M30b34 E30 twin-screw supercharged muscle car

Right. My trans is a g240 btw. It a good bit shorter than a 265. I'm hoping that I can get away with a unmodified combo driveshaft or like chondamx said, an m20 g260 one.

Then you may be able to. I had to take IIRC I took like 2 inches out of it.

Just to ask - why not cut the firewall and fab it to fit around the motor instead of just beating on it? I'm asking simply because I have never seen anyone approach this swap with any other thoughts besides "just beat it in." Don't get me wrong, I like what you're doing (and considered it myself) but just thought I would ask.

That little G240 looks cute behind that tank of an engine--me limey! Also, cross hatching looks muy bueno. How deep are those score marks at the top of the cylinder? Maybe fill them in with some JB weld?

Hey chondamx, how's your turbo build coming along?

That's doing to much. It's easier to beat it. Takes like 10 min tops.

diggin the progress!

i used the m10/g240 driveshaft for my build and that required 2 3/4" cut out of it.

for your radiator mock up, is the core support in place? i don't think you can get the e30 radiator in there, it's super tight already when using the e28 535i radiator. the distributor is literally less than 5mm from the radiator.

Much slower than this . All shit-giving aside, you're making awesome progress! If you need a hand give me a shout--its always a pretty drive out.

EDIT: I changed my sig just for you.

I used to be a Land Rover tech.

In the Discovery Series II, the v8 engine is installed as an assembled unit (obviously), and is an incredibly tight fit against the firewall. So tight that it is impossible to get a socket on one of the rearmost head bolts (let alone lift the head off) due to the overhang of the firewall. The actual, official, published service manual, direct from Land Rover to dealerships, includes a step that has a diagram showing exactly where to hammer the firewall, and how deeply to smash it in, in order to get enough clearance to perform a head gasket job.

If a few well placed hammer blows is all it takes to fit the engine, that is certainly a lot easier than modifying the design of the firewall. I mean, if Land Rover engineers didn't even think it was worth redesigning the firewall to accommodate the engine they designed and sold the vehicle with, then it certainly isn't worth it for our 25 year old cars.

I spent a few hours mixing and matching some driveshafts to get a short enough shaft to fit with the g265 I'm swapping in with my m30. It may be of some use to you.

I'll do it bro.
And I love your new sig, I lol-ed.

I just read that. So good infos. And like I said on your thread, there needs to be a thread devoted to the different driveshaft sections, lengths, and compatibility. It would be a resource for sure.

My understanding is:
g260 works with a stock length driveshaft. Either with the stock output flange and a large guibo e30 shaft, or swap to a small output flange and use the I shaft.

G265 requires a shortened e30 shaft (with the flanges mentioned above), and maybe, if I get lucky, some combination of auto e30 and manual e28 parts.

As for your swap, I have no idea. Is the g240 shorter than the g260?

[econti]

Will the 240 actually handle the torque?

[Ether-D]

The 240 supposedly handles up-to 300 lb/ft of torque before exploding. I plan to be in that range eventually. I think.

And I think the 240 is shorter than the 260.
