Engine swap, Think I'm the first to do so if I do

I have heard from a few guys that the 300m engine has similar mounting points on the engine as the 93 3.5. I am thinking about swapping in either the 300m or the special edition along with the tranny. The width is the same on both cars also I believe.
Do you guys have a for sure on the mounting locations being similar on the 300m engine and the 3.5 tsi?
Thanks
-Matt

I personally don't think the swap is worth it. The transmission is the same, EXACTLY the same, so don't think you're making a difference here except that it is newer.

Agreed. To me, it wouldn't be worth the money to swap out an older 3.5 for the 300M 3.5, assuming your 3.5 is still in working order.

The reason why I'm thinkin of doing so is because of the power is a bit higher, the tranny is the same but it has the electric shift ( I forget what its called) I have already blown the rod bearing outa my first engine. So I'm on the second engine here. My dad and I are thinkin of getting some engine work done by a local shop called HO Performance, They handle boring, custom pistons, etc. It shouldn't be to much money I figure. Find a nice 300m, drive a rusted out car without high end insurence. Then go really fast and rear end the car. lol righting it off I will get out and say.... "can I have the engine?" haha, doesn't work like that I guess. I'm sure I can find a new engine and tranny at a local engine shop.
any more input?

all I can say is good luck getting it to work right

we had another member who upgraded from a 2.7 to a 300M 3.5 motor, he tried using both the OEM computer as well as the 300M unit and was having trouble with both of them

What kind of problems??? I think its pretty straight forward... Using the 300m engine and Factory ECU and the 300m tranny bolted on, So what kind of problems?

Your tranny and the 300m tranny are both exactly the same (42LE). The "electronic shifting" also known as autostick, can also be added to your current tranny. There has been at least 1 person on these boards to has added the autostick to their car.

if you want autostick, you're gonna need the TCM for sure, too

Having the Vision from day 1, My dad and I now know that The tranny for some reason doesn't hold up as well as the newer ones. We have our 2nd tranny in there. I dont know why but we have had not much luck. Same with the engine as I have previously posted. With putting the new engine and tranny in I think I should be able to run the car a bit harder and know that the engine wont go, along with the tranny goin in 60,000k

As stated above, the tranny's are exactly the same. Unfortunately, the newer ones don't hold up any better than the one you have. It's a common problem us LH owners have to realize and deal with.

Don't expect to put in a 300m tranny and ride it harder and not have any problems.

The TCM controls the autostick function.
