Increasing my torque a bit?
 

I have a 2002 Daewoo Lanos with the 1.5SOHC engine. Its quite gutless as you can imagine. Whats the best way to get a bit of power from the line?

I was guessing a 4-2-1 headers, 2" exhaust and a custom intake? is there anything im missing? or am on the total opposite track?

American market Lanos' were equipped with 1.6 DOHC engines.

For low end torque, a campy trick in the SOHC dodge camps was to change the cam timing with an offset key... you could shift the peaks up and down a few hundred RPM by that alone.

You could also try a port and polish on your intake manifold, I did that and I dynoed the tq jump from 196 lb. ft to 219 lb. ft

Type-H, I don't think a 1.5L is going to produce torque in equal quantities to yours. Let's not get someone excited here...

190 to 210 is a little over 10%... on a 120Lb/ft engine, that'd be 132lb/ft.

That's a *little* optimistic, but not a bad goal smile.gif

Mike;

Mine is a 1.5 I am sure of it. In my owners manual it shows the 1.5 and the 1.6 DOHC, and the difference is clear, i have the 1.5. I live in Canada if that makes a diff?

So what was this other trick you mentioned? any links to that?

The problem is that you're dealing with two totally seperate engines. Headwork doesn't put another 10% gain on every car...

A back-to-back dyno test of a BETA with and without headwork, my motor gained about 2 wheel horsepower. That's headwork in combination with intake, throttlebody, intake manifold, intake cam, HVE header, full exhaust, one of the only chipped Tiburon ECU's in the country and an S-AFC.

Two horsepower. Let me tell you how excited I was that I spent $450 on two horsepower... rolleyes.gif

There is no general rule for engine work gains. I am stressing to Type-H and anyone else listening that you should never use your OWN gains to promote work to someone else's car unless you're dealing with the same platform.

If Type-H was suggesting headwork to another 2.5L 4-cylinder owner, then he would be making a good recommendation. But his experience with the 2.5L isn't going to cross over to the 1.5L -- for better OR worse.

Sorry about that rolleyes.gif
