Hi everybody , I have lancia dedra 1.6 ie with engine code 835A1000 90 hp Weber MIW centerjet 2 injection system, I hope to increase the power for this engine to 120-130 hp what the best modification can I do for this engine .
Engine data:
Bore x Stroke : 86.4x67.4

Well, that's a problem we can't solve for you, I'm afraid...

What about swap the fuel injection system from SPI to MPI from engine 159B9000, replace the intake manifold with its common rail and injector , and also replace the wiring harness to 195B9 and fule pump,

If you have acces to all those parts, why not change the whole engine...?
