Hi fairly new to this site, I have a 2.8i XR4i. The engine is showing signs of wear, smoking a little from the valve seals.

Unsure what to do repair my engine using new heads modded for unleaded then try and find a turbo technics kit for it or go for the 24v cosworth engine.

If I went for the 24v conversion I will need to know exactly what work is involved as I dont want the car to be off the road for long.

Thanks in advance
