More Power, Tired '75 1.8 Options

[19144jt]

Hi,
I've got a 1975 1.8 that still runs pretty good but is getting tired. I am tryng hard to keep the car original so I would like to keep the fuel injection. When I rebuild the engine, am I limited to staying stock (for purposes of keeping the fuel injection) or are there some things I can do to get mild (or better) HP increases and not have to carburete? Any ideas would be appreciated.

the absolute easiest way to gain HP is to have the entire rotating assembley balenced. This allows for less friction. Less friction allows for less heat. Less heat means more HP. More HP means more VAROOOOMMMMMM!

You can increase the CR to a point. From what I understand, L-jet cant take as much added compression as a carbed system but it's better than an older D-jet system in this reguard.

You can add displacement as was mentioned before. The most common way is to add the crank from the 2 L engine and bore out your 1.8 L piston to 96 mm. You'll end up with 2056 cc and with a good cam you can expect around 110 hp with a good head rebuild. Nothing fancy on the heads, just slightly larger valves and good sealing to the cylinders.

Before you start spending money, ask lots of questions and buy some book ect and learn or else you'll waste $ and time.
