I will make a detailed posting on this swap with a video of a k20 expert if someone decides to go down this road. It is a challenging swap that needs a lot of little parts from both Toyota and Honda.
I would like to thank the following:

Jordan
Jeff, Dave and Micheal at Honda parts
Richardson's Radiator in Langley
Joe
Wayne at Garage 5
Ken
Lordco
Bill at Indy
Kelvin and Jake

There are many more mods coming so I will update the thread as it happens. Any questions just ask me :)

Long delay but here is the parts post and video.

If you are thinking of a k20 swap into the MR2, I recommend that you watch this video on NA or FI, what part to upgrade depending on the type of k20, etc.

I went with a k20a2 from a 2003 Acura RSX typeS to swap into my 1993 MR2 turbo using the e153 transmission.
Reasons why I went with this motor are:
-cable operated throttle body
-strong internals, very thick cylinder wall sleeves compared to the other k20's
-minor upgrades to stock long block for big power (ex: valve springs and timing chain tensioner)
-the k20a2 has the best flowing head

You can also use the k24a2 motor from a TSX which is 2.4L for more torque.
There is a Frankenstein builds like a k24 bottom end with a k20a2 head.

Here is a link: http://www.hybrid-racing.com/blog/k20k2 ... ine-build/
Parts: http://afhkparts.com/shop/kswap-honda-p ... package-3/

I used the E153 transmission because it is built to handle high hp and tq. (+-650). I also replaced both axle shaft seals.
Below are the part numbers and fluid:
Passenger side seal 90311-40004
Drivers side seal 90311-50027 (large in size compared to the pass. side)
3.5L of redline MT90



To be continued..
