2GR "engine-in" maintenance

Anyone have any experience performing maintenance items with the 2GR in place in a SW20?

I'm going to have to change the alternator and there's not a lot of room it seems.
But maybe by supporting the engine and pivoting down on the LH transmission mount...

Just wondering if anyone has tried doing things like alternator or water pump without dropping the motor.

i have replaced the water pump on a 2gr in chassis. you have to support the motor from the bottom and remove the motor mount. after that you remove the pulley and you can just sneak out the water pump. Installation is actually relatively easy because the gasket is dry so you aren't making a mess of things due to tight clearances.

To be fair the only reason i did the water pump was because of my early supercharger belt routing stuff required pulleys to be mounted on it. i haven't actually had a water pump failure.

The alternator is also possible, i've done one to replace a squeaky pulley. I don't remember if i disconnected the exhaust and front/rear motor mounts to tilt the motor but i'm pretty sure i did. I'm not sure this could be done without removing the A/C compressor if you had that in place. You could probably zip tie it out of the way without discharging it but it would be a non trivial service.

I did this in my Spyder (ZZW30) with my 2GR swap.

I suspended the engine on the right side a bit using a jack, then I removed the right side (if you are facing the rear) motor mount. After removing the belt and unbolting the alternator the longest part was wiggling the alternator past the hoses in that tight space.

The new alternator ($129 on eBay) went back in the same way, with lots of orienting and squeezing through tight spots.

The whole thing took me about 3 hours.

If you would like I have pictures of the whole process but keep in mind I have a Spyder not a second gen MR2.
