Hi my mate is fitting a rst conversion in my 90 spec XR3i whilst I'm workin in Canada (I work 4 the army) 4 me at his garage. The thing is I'm wondering about converting it to efi spec using the inlet manifold off the XR could anyone tell me what else is involved and what are the advantages of running it? Any help would be much appreciated.
Thanks...Pete

 

efi is better but you would need the ecu and other bits off a frst
