Wow, looks like I am not the only "CRAZY" person on here. I too am fitting a SR20DE to a 1200 ute. I am almost done except I am missing the most important bit, the engine (wanna sell me yours )

Compression, on 98 octain I would push 10.5:1 or even 11:1 with a good tune.

Big cams work well with good compression (and a good breathing head). Try Crower as they have plenty of SR stuff or even look into a custom gring through Crow Cams or Cam Tech etc.

I could not give you specifics but higher lift and increased duration will allow more air/fuel in and exhaust out. Dont forget to upgrade the springs to suit *and the rest of the valve train).

With the box I am un-sure but I reccon you will atleast need the SR20 bellhousing. I am using a SR20 gearbox in my conversion because I came accross one for cheap.

As with the max power, this a stab in the dark but I reccon 180 to 200kw's at the flywheel would reasonable from a worked motor

If you dont mind saying how much did you pay for your SR, where did you get it from and what did you actually get.

Hope this helps, keep intouch.
