M104 Turbo Powered Datsun
Hey, I searched but I think it's safe to say that this has never been done before in either the Mercedes or Japanese world ... So, Here we go
I emailed quite a while ago Turbo E320 about the idea of putting an M104 engine inside my 1971 Datsun 240Z. Not because I want to be different or special, but mostly because the engine, in my opinion, is far better designed and executed than anything that has come out of the land of the rising sun. Anywho, a few weeks ago I managed to find a .941 block w/ oil squirters, two separate heads (.941 head and .99x head) and a 350SD Crank to start the entire process. So far I've found out that it *should* fit in there, and that there's enough room for me to fab up an intake, turbo manifold, and all the other fun bits to make it go. At any rate, I started toying with the motor last weekend so see what it would take to make it run, when I realized the 350 crank has a giant stroke. I've been looking for a deck height to the M104 (219.675 sound right?) as well as what was used by AMG for rod length and compression height. I've also attempted putting the 280 rod on the 350 crank (I knew it was going to be way too long) and noticed that the rod width was 22mm while the crank width was 28mm, which seemed a bit extreme. Any thoughts, or questions would be greatly appreciated, as I'm shooting for a 90mm bore (over the 89.9 stock, would make pistons much cheaper) and the 92.4 mm 350 stroke with (hopefully) somewhere in the range of 8.8:1 CR.

If using the 350SDL/C36 crank you'll need to have the wrist pins much higher up the piston than stock, rather than using shorter rods. I did the same thing without increasing the bore that much.

awesome concept. would love to see an m104 in any datsun
for a while i was thinking of putting a 190e 2.3-16v engine into a datsun 510, but according to a friend of mine who has owned several 510's, that engine will be too heavy for the car and throw it off balance. |

How Heavy is a cossie motor? The L4 isn't exactly a featherweight, and the most common swap is an SR which is 50lbs heavier than that. I think a 2.3-16 with the 5 speed would make for a disgustingly quick 510.
Though I may not be going for a Benz motivated Z car. I've ridden in a 190e. What a fantastic car |
