I'm pretty sure it's not a Fidanza. However, is the Pressure plate mounting points located above the friction surface, ala ze 'chermans? If so, that means that, afaik, none of the standard datsun pressure plates or clutch disks will work with it. At least not stock anyway.

Give it a year. I'm sure some little high school prick who's daddy bought them one so they could be cool will wrap one around a telephone poll soon enough.

Sounds like a good project. If your wondering if it's too much power, have you driven a car with a power to weight ratio of about 5lb/hp? That's about what you're barking at and before you plunge all sorts of money in it you may wanna find someone with a car that has those kind of numbers and have him scare the ever loving hell out of you.

I guess I'll finally say something 'bout my project. I'm going to finally heave the L-gata out of my 71 240Z and try and cram in my M104 with a little assistance from Mr. Snail. The nice ol' gal... Here's what is going in it. 3.0L, ditching the CIS, since it sucks, and going with Megasquirt. So far I've got the thing ripped apart Something like this... Mercedes made a fully forged bottom end because they love me... Including forged rods and Mahle Silicon coated pistons. So now that it's all apart, I'll finally pull the L28 and mock up with my spare block, head, and oil pan to see what all exciting things I get to do next. After that's all done to make sure she'll fit, I need to make an adapter plate to use a BMW/Getrag 260/265 transmission (cheap and strong) and find an HX40 and make an exhaust mani once I figure out room concerns. Stock motor is 230bhp from the factory on crap CIS. Goal for this project is 400hp/400tq at the wheels which from what I can figure, should happen at about 12psi roughly on a good tune.

Wouldn't touch Kumho or Hankook in that tire size. I've seen some and run some on a Mini with 13's and that don't hold up. Yokohama makes a good sticky compound as well as Falken (sp?). I've never dealt with the others but I think they could probably be trusted.

It's full floating. But here's the interesting point. The small end of the rod is what is milled for clearance. There's no more than .002 slop in the top. At the big end, there is probably a quarter inch rock back and forth. I was wondering if there were any other engines that got this little bit of technology. A quick trip to google showed that apparently Joe Gibbs and Hendrix have been using them very recently in Nascar. Edit: I pose this question since this has been used in Mercedes since the inception of the M103 in 1984ish. The reasoning behind it is that if I go to MBZ and ask for a set of stock replacement pistons they want 374 bucks a piece and the only company I've talked to (Ross, CP, Wiseco, JE, etc.) personally that said they could do it with standard forgings was JE, in fact, they're really the only people that have any knowledge of them. Ironically Wiseco just got a set of pistons in their tech dept that have piston guided rods and they're just as new to it as I am.

It's a fantastic movie. And about twice as long as it needs to be. I'm not patient enough to be planted on my keister for 3 hours.

I'd put that on the wall.

Well I was tearing down my JY motor to build so it can go in the Z car when I found an interesting bit of technology that this engine uses: Piston Guided connecting rods, meaning that the piston is what dictates fore-aft movement of the rod, and not the crankshaft. I personally have never seen it before, and have really only read of it recently in NASCAR and on other MBZ engines. Anyone care to weigh in on this? I've took a few crappy pics, I apologize before hand for the useless Macro feature on my camera.

Looks like a 720 trans with a Z series bellhousing. Z engine, not Z car.

Depends on the class. The majority afaik are push started.

This thread needs new life. Christmas came somewhat belated yesterday when I found an somewhat rare (in my searchings) M104.980 euro motor for 100 bucks at the JY, including the .98 specific intake manifold and water pump. Took me 8 hours to get the thing out (Mercedes could not possibly integrate an engine more than that if they tried) and it was freezing cold, but an excellent, what appears to be relatively low miles score indeed.

I feel cryotreating any part would have probably quite a small effect (in the grand scope of things) on the total yield strength of a metal, however the ability of the material to withstand shock loading is probably altered. I.e. how well a crank or rods can deal with detonation, providing it's the impulse of the combustion event that's breaking the bits and not the total gross loading on the part.

I'm going to guess... 9volt battery with an array of IR LED's, he's creating a transmission array to be picked up by a sensor on some bit of robotics to sense some function. If that's the case than you could start with a 33ohm, and in the event you find you'd like a little more signal strength than you could go to a 30ohm and be safe.

Hitler believes this is a meaningless persuit. Hmm... Not sure how to take that.

I'd like to know what kind of flow distribution that manifold provides.

People from NZ and Australia should not be allowed to post that kind of material on this site. That's just not fair.

I can stack the FSM's I have for the Z (I've got one for an S130 and S30), the Mini's, and the 720 together and they don't equal one of the two for either my mom's new beetle or my brother's Explorer. My attention span is not long enough to work on a car with a manual that could show up an unabridged dictionary.

Both videos have this exact phrase in them... aw sh**, aw f***, that's not f***in good. Same man? It appears to be similar handywork.

Compared to a mini or an MG, a Datsun is practically rust proof!

If that's the factory supercharged engine, than it's not an open deck like all the other northstars, it's a different block and an entirely different animal (much more rare and expensive than your dime a dozen JY Northstar). CHR Fab builds a bunch of these motors for performance applications, if you want big numbers they're the people to contact. And getting big power numbers is not a problem with an open deck motor. It's getting them to live (for any extended period of time) at these power levels. 470hp may seem like a ballistic missile to some and a ho-hum grandma mobile to others. It's all about your frame of reference. When you get to what those kind of people would call big power (remember there are at least a few people on this board that have well over 800hp to weild under their right foot) CHR Fab is the only people I know of that stock darton sleeves for the Northstar.

Nah, the M113 isn't exactly a rocket ship, but it's got some pretty good push behind it and for 4.3L it will pretty much unhinge the earth from its axis down low. You're correct in your assessment that most MB engines are built for more torque down low, it's why all the TT V12's from all the MB tuners may make 'only' 700ish hp give or take but have to be limited as the torque approaches semi-truck diesel levels. It's a good car though and as long as you find someone that has kept good care of it you should see lots of good miles out of it. The W202 platform is a carryover from the old non-chrysler days so It's still holding on for dear life.
