Default Mechanical barriers to a BRZ FA20 in a GC?

Anyone know what physical barriers there are to bolting a BRZ FA20 in a GC chassis with an AWD transmission?

Thanks for any help.

AWD trans will bolt up to a FA20, if the trans stays in the same location and I dont see why it would move you can use your driveshaft.

In a BRZ the starter is on the opposite side but the block is shaped to accept a starter on either side so you can keep it just as it is in your car.

Mechanically this swap would be fairly straight forward, electronically it would be a bit harder unless you delete the Direct Injection

One of my friends is working on it, not sure how far along he is.

Yeah, I was thinking I could run the port injection off a megasquirt or something like that. I assume the BRZ ECU probably wouldn't run without other BRZ electronics connected to it via the CAN bus. Thanks for the help.

Do you know if he's run into any serious difficulties?

Contact iWire regarding the wiring, I believe they are working on something to make this swap possible.

Why in the world would you want to go through all that trouble for a 200 HP engine? It makes no sense at all to do this. A 2.5 RS engine with cams and a header will get close to the same output with a **** ton less hassle if you are turbo averse.

Will it though?

I read of people who have reliability problems with the cams, even the 1500 grind. Main reason why I haven't put any on yet. The ej251 doesn't seem too keen on more HP from SC/TC. As far as I know, I haven't heard of too many problems with the FA20 being blown. Guy never said he wasn't turboing either.

How has the FA20 go on reliability? EJ's are old. It would be nice to be able to put in a newer, hopefully more stable engine in the near future.

Also, not that it matters (this isn't a Honda...), but there is the matter of that extra 900 (?) rpm.

OP, I'm interested to see if you follow through. Would also like to consider this as an option vs. getting a k or g engine.
