It's likely to be the 2 litre four cylinder unit which powered the Fiat Croma during the '85-'90 era. It's a good unit, with a twin-cam eight valve head (unusual now, most fours now have 16 valves).
I'm pretty certain that Lancia used the same motor in the Delta Integrale rally car with a sixteen valve head and a pair of Garrett T3 turbochargers. These could shove out 200 bhp with ease.
The injection system would be the Bosch K-Jetronic system, which was the first mass market EFi system produced that worked reliably. Earlier cars still used Weber carbs, but a pair of DCOE's makes a wonderful noise as well as throttle response so fast it almost anticipated your foot going down. They are very very tuneable, although it's a specialist market.
The Bosch K system is not tuneable unless you resort to high flow injectors etc. You'll also need to make sure the fuel pump can deliver enough to stop lean running as this will cause excessive heat in the combustion chambers with risk of burning valve seats (esp. exhaust).
This sounds like a truly fun project. |
