Yes that is seeming like the most suitable option. It will have to be an XR2i as if a carb is installed the emissions will go through the roof (unless I run it extremely lean for the MOT) :P

So for the XR2i model what components will need modifying or required?

Block
Engine mounts
Loom & ignition setup
Coolant system hosing
Inlet & Exhaust manifold inc. full system
Possibly a swirl pot setup coolant as well as fuel?

I reckon I can use the gearbox I have already as the final drive ratio isn't off the scale compared to the XR2i box. Yes top end may be at a loss but raw acceleration is what i'm after with more usable power on the road.

Someone please confirm what the swap needs so I can price up some parts.
