1.8 Liter HO forced induction or any other significant upgrades available?

[Michael Lewis]

Does anyone sell a forced induction kit for the 1.8 Liter HO engines, such as a supercharger or turbo kit? Obviously this would be very expensive if it existed but I am curious.

What about just a simple ECU flash tune, are these available?

If not, what are the most effective engine upgrades that can be done to these N/A 1.8 liter engines?

You should find lots of info in postings from @swatski.

No super significant power upgrades for those 1.8 N/A engines. Unless you go with the SVHO and play with ECU reflashes to gain boost, change impeller pitch, take advantage of their the bigger (160mm) pump.

For N/As the ECU RIVA reflash is nice, smooths out the throttle range and gives some torque in mid range and better fuel economy/range for cruising. It is noticeable but not what I would call major.

No S/C or turbo kits. There were some turbo 1.8 conversions in skis but those tend to blow up.

Ribbon delete helps, beyond that the most significant power gains come from sealing and porting the pumps.
