Well I've been driving my S12 for about 10 years now, and have put on about 120,000 miles of my own. I have finally decided to toss the CA20E and go with the SR20DET. I need some info on what will need to be fabricated or what will switch over from other models to make it fit. I have the Live Solid Rear Axle. As far as motor mounts, driveshaft what will need to be done. This will be my first swap and I am determined to do it myself with the help of a few friends. I am mechanically knowledgable. One of my friends mentioned that I might need to run both computers, Ca20, and sr to make all of my electronics run. I plan on switching out my cluster to the s13 analog with HUD versus my digital one. I like it, but I would like the analog/digital combo better. Would I need to relocate anything? Any feedback would be much appreciated.

Sr20det Swap, Need Info
From my little research since I've been on here.
You can use SR/KA mounts on the ca engine mount brackets. Custom transmission bracket if you use the sr/ka transmission and will need to cut back a little sheet metal where the shifter hole is a couple inches back. With sr/ka transmission you'll need to shorten the drive shaft also. There's a couple ways of doing it, I'm sure someone is bound to chime in and help, or tell you to search. So you may as well do some searching now. Sorry couldn't help more.
every thing silverarrow27 says it true. check my cardomain for more info on the swap. I made a page on their with swap info. I also have pix of the trans mount and hole for the shifter. and lots of other pix of the swap. and no you will not need the old ca20 ecu any more.
