Buy the 255 HP and a good ajustable regulator.

Why don't you go onto vendor websites and look? I know you're new; I'm not trying to be hard on you, I just want you to know in order to survive on this board you need to be willing to do a little research on your own.

Between the Walbro 190 and the 255. The 190 depending where you look is about $80-$120 and the 255 is like $120-$150. Thats just what i have seen.

The 255HP is better at handling higher pressures. Fuel pressure goes up with boost, so on a high boost car the 255HP helps a lot. At 0psi and below they pretty much flow the same, so on an car that isn't boosted and runs a normal fuel pressure of 43psi, there is pretty much no difference between the two.

Well i just got myself a new 190. So im good.
