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?

 

I think the guys from Jamaica will pipe up here... afaik this is the engine they get, and over in europe.

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...

 

Never compare the quantities.. compare the percentages smile.gif

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
