Nice layout of the parts.

That's a nice setup right there. Good stuff!

You think the 245 can handle as much power as the 260?

I haven't done any testing to say, but I do know of a number of guys running 550hp through them without issue.

M20 Oil System

Since I'm doing a stroker engine with forged internals and other fancy bits I'll be running an oil cooler. I know this has been a source of debate between qualified forum members, and I am of the opinion it is necessary on this kind of build. In any case, I think of it as good insurance.
--------------------------------------------------
Original Goal:
To run a remote oil filter in conjunction with an oil cooler.

Issues and solutions:
-Remote filter mount so I didn't have to get cramped squeezing my arm past the narrower '02 frame rail, suspension bits, and tubular headers when I need to reach the oil filter. (solved by the remote filter bloc)
-Add more clearance between oiling system and the hot headers (solved by 90' Rotating Remote Filter Adapter)
-off-engine mounting provisions for the oil pressure and oil temp gauge senders (solved by the remote filter block)
-Use a thermostat for the oil cooler since this is a street car (solved by the thermostatic sandwich filter)

Running a 19 row Setrab oil cooler. Canton Remote filter adapter and mounting block, and an Earl's thermostatic sandwich filter. Also running the fancy braided fabric AN lines and fittings.

If anyone would like the parts list, just PM or email me.

Here's a rough layout I drew up to better illustrate what's going on.



Layed out



I'll try and mount the cooler behind the front passenger side headlight, similar to the #13 car, just on the other side.

The 260 was drained and the weights taken from two different scales.

I'll be blunt here, the only upside to using the getrag 260 is the initial cost is lower (and the 245 is trickier to find). In all other aspects that I've considered they are equal (robustness for example) or the 245 is better. It makes for a much more efficient and clean overall installation.

That being said, as I mentioned earlier there is nothing wrong in using the 260 as it will get the job done, but just as long as the person doing the work is comfortable and methodical in his fabrication.

I'm going with the 260 because its what I have and I like that it came from an E30. Also you can run any E30 SSK assuming you run the rear carrier bearing.

Not too excited about cutting up the trans tunnel though. They both have their pros and cons.

It looks like the 245 is open....is the getrag 260 empty or does it still have fluids?


Thanks for the info Andrew. I'll definately think about using the e30 subframe...I'll have to take some measurements and look at the 02. But I'm definately going with the 260 for its robustness and their availability/price. (So sounds like my 02 will be e30 with 02 shell and front subframe).

Looks like the shift carrier to me.

[jalopi]

what's this thing?

[Hooffenstein HD]

The 245 is from a 323i or a 320i?

E21 320i/6, or 323i and early(up to 1984?) E30 6 cylinders from my experience anyway.

[kid325e]

Rad picture. You can see how that 12 lbs really stacks up in the Bellhousing area.

The 245 is from a 323i or a 320i? Thanks for doing the detailed write-ups. Definitely a nice change to see from the usual write-ups you see. I think i'll be ordering one of those transmission mount brackets here soon..

I prefer black wrinkle painted valve covers also, but remembered that the Cecotto Edition E30 M3 came with red.

Of course he was Italian.

I did not know that existed! Very cool.

Any new updates or things in the works? I know you been busy with your new little guy! Cheers to a new year.

Thanks! He's a pretty good kid; eats, poops, pees, and grunts.

I’m getting geared up for the transmission’s rebuild (ba-dum-cha) along with a couple more AN fittings for the oil cooler. For the transmission I got some new synchros and a couple other internal bits on the way from BMW. Synchros are now $66 each list price, ouch. I’ll try and take the time to do a good rebuild tutorial again.





Out of curiosity I sized up the differences between the E21 323i getrag 245 and the E30 325i getrag 260. You can see how the 323i tranny would fit much easier.

The 245 weighed 62 pounds
The 260 weighed 74 pounds
So the Getrag 245 is 12 pounds lighter than the 260.

bleh red engine cover? its not a ferarri. german machines look best in black
