Pull-A-Part sells transmissions for $75 each. It takes all of 45 minutes to have one on the ground in a fully dressed car.
Goal of 225 WHP for the car, waiting on a forged motor. Tips?

I know, I just meant because I've heard the FS engine is extremely weak in a durability sense, which is why I went for the upgrade.
Are the AWR motor mounts a good upgrade or should I look for something else? I really appreciate the help.

Solid motor mounts help save your transmission and put power to the road.
Awr is great. You could also buy a set of oem mounts and fill them with 3m window weld polyurethane. That will save a lot of money and it is a nice balance between ride comfort and firmness.

Actually, the FS is incredibly durable as a daily driver. It's only when you start wanting it to become something more than the heart of a grocery getter that it starts becoming problematic.

I can agree with that, I'm actually surprised that I haven't killed mine yet. It's been parked for about 2-3 years now but prior to that I had boost creep city upwards of 18+ lbs of boost at anything over 5k rpms with the stock ECU. The stupid car would literally out run a mildly bolted stock tuned evo 9 or 10, that's not to say it would run laps but it would pull slowly.
Edit: I think a lot of it has to do with not lugging the car down in low rpms with high boost and driving around the stock ecu tuning.

AWR mounts are the best you can get, but they do change the feel of the car and it will shake more. You get used to it and I would never go back to stock mounts. The FS block itself is supposed to be good to 700hp, the rods are the weak point that can snap at low power. Frequently (as was the case with my second MSP before I bought it) people run the car low on oil and ruin the main or rod bearings. They get hot, expand and seize, zoom zoom boom.
Eh, I bought the car at 98,000 miles and it blew two weeks later. The only thing the previous owner did to it was an Injen CAI. Maybe he was bad at maintaining it, I dunno.

Does that seem reasonable?

That's a little premature for an engine to fail but it happens, my second MSP went at 110k. Probably was ran low on oil because the rod bearings started knocking and it blew soon after. That link isn't the complete engine mount set, it has the front and rear and inserts for the side mounts.

It won't make a huge difference either way, but you may as well do it right the first time. If you are dropping more than the value of the car on a new forged motor then a good set of motor mounts should be necessary.
