If you ask people "is it better to mod a 1.8L or replace it with a 2.0L and mod that" quite a lot will say to start with the 2.0 - they say this because they understand that you can spend thousands on a 1.8L increasing HP and far less just swapping it out for a larger displacement engine that has the same amount of power as the modded 1.8L.
In other words people have no problem understanding cost/benefit calculations when it comes to getting more HP with increasing displacement.
But, for some reason when it comes to what I call "barnyard performance mods", a lot of people's logic and understanding of cost/benefit goes right out the window.
They myth that 20-30hp is just available for 3 hours Saturday morning's work with about 25 bucks worth of tools and $100 worth of parts just doesen't seem to want to die.
From the looks of it the OP left this thread a long time ago, so we are just arguing for the fun of it, now...
The only one talking "barnyard mods" is you. Please stop adding garbage to this thread.
