my goal is running about 14lbs and want to know whats are maybe some rod/piston combo people are running and can recommed to me and maybe some pros and cons about them. My car is mainly street.

Also how low in compresion should i drop? what will the drivability of my car be like if i drop to lets say 8.5 or 9

Ive searched but just havent gotten what i needed to know.

Eagle rods and Arias or Je pistons. Eagle are the bang for the buck!

For the street I would stick with 10:1 compression.

Your car would be a little more sluggish on lower compression.

Eagle rods......JE pistons

Colin thanks alot for the GB info.....

The reson why i wanted to lower the compresion was because i wanted to run more boost and not have to run higher octane. Its a daily driven car so pumping up on expansive gas is something i want to stay steer away from.

I think stock is 10.5:1 IS there a rule of thumb to about how much more boost you can compensate for a certain amount of compresion lost through pistons?

Ive seen cars with stock compresion run little under 10lbs with 91 octane.

You are looking at it the wrong way.

Octane has a direct relationship with HP not boost.....

You can make the same hp on a car that has a higher compression and low boost as compared to a car with low comp and more boost.

thats what I thought - but why does everyone lower their compression?

Gotcha so its a give and take situation...So if i understand what your saying, no matter what if i want more HP, im going to need to run higher octane?

Yes, to be safer!
