So I just got my bottom end rebuilt, darton sleeves stock bore eagle rods and wiseco pistons. just wondering if it will be safe for me to drive the car to break it in. the only thing really different is the compression, its like 9:1 or 9.5:1. I just want to know if it will be ok to drive. The car has a peakboost turbo kit and tuned with Neptune originally.

just want to know if lowering the compression will mess my tune up. I wont be able to get it tuned till next week but I wanted to drive it to work out any bugs b4 I go to get it tuned.

Thanks

 

if u have a wideband O2 sensor, than its ok, aslong as the AF is good.

What was the comp. before?

 

whatever a stock usdm b16a2 compression is ha. I have an aem uego and I took it for a drive and if I get on it its like around 10 or 11 but as soon as I let off it goes to like 18 then it shows---. also if I like hit the gas real quick it goes lean to like 15 for a split second then it goes to 10-11ish

 

i dont think it will be a big deal, but i still wouldn't chance it by boosting on it until you're tuned...
