Scrantonsgarage showed how they do it

Yes, look up Kennedy engineering online. They have many many different adapter plates available for all kinds of engines. Also, if this is for a Subaru transmission, Subarugears (the company) makes adapter plates for all sorts of engines for these transmissions

For this application, it was 1.228" thick

So you are adapting 2 metric mechanical items but still insitting on imperial measurements on the adaptor plate?

Well the main things you should think about is how you will mate the engine and transmission together, engine mounts, cooling system, intake system, exhaust system, and how you plan on running the engine. (Wiring harness and ecu)

The thickness of the adapter plate was figured out first

@@timshop2700 Based on what though? An original engine/transmission mate doesn’t have that extra space, so what allows for an extra inch plus for an adapter, a thicker clutch? How did you calculate the thickness of the adapter?

@77magnuss I took a Subaru transmission and measured the point at which the input shaft rides in the pilot bearing. Then I measured where the flywheel sits on the block. After some messing around, adding, and subtracting, you come up with a necessary thickness for the adapter plate because of where the pilot bearing rides/input shaft location. Kind of a hard thing to explain

@@timshop2700 Ok. Yeah, probably easier to visual with parts in front of you. I’m considering a swap into a Porsche 944 and this is the step I’m not sure about, but obviously it can be done. Everyone who has done videos skips over the calculation of this. I’ve been trying to find something with the basic concept explained but so far I haven’t. Thanks

1zz bolt pattern is completely different from 2zz and every other engine.

Need your help bro

Try Kennedy Engineering. They have a whole list of engines and transmissions they can adapt to. If not them, you'll have to make your own following the advice of the youtuber: Modify Up

Nice
