More Power from engine.

[DArkstalker]

Can someone give some suggestions for getting more power out of my 2.2l engine. I already have an SRI, spark plug wires/sparkplugs, and exhaust.

You can get the UD Pulley from 360Dynamics which adds something like 22HP at some points in the power range.

You can get your head ported and polished.

You can bore out your TB.

You can get a custom set of headers made.

You can shed all of the spare junk that you never use like spare tire, jack, tools, back seat, interior plastic etc.

Or, you can go for the holy grail of Daewoo modifications and get a nice turbo setup and get your Leganza to some high HP levels. It is pricey @ $1500-$3000 but it is by far the best bang for your buck.

The Leganza allready has the larger throttlebody... in my opinion it would be a waste of time to pursue a big bore Throttle body.

If you don't want to go with a turbo..... a "wet" nitrous install is quick cheap power....but it can get costly if your using it all the time and it's a pain to get it filled up all the time.

The head porting and polishing might make a few horsepower in the top end of the RPM scale but you would risk loosing power in the lower area of the power band..... so if your after "pure" power then the port/polish idea is good... but for every day driveability I wouldn't bother.

Headers and cams are available.... but they are fairly expensive.

I totally agree with the "shed some weight" idea..... the leganza is full of thick heavy carpet and the seats are pretty heavy.

Turbos are allways great but I would double that price if you need to get someone else to do the work for you.
