sorry if i post this in the wrong topic....

a few more weeks from now..i might be puttin back my bro's old High compression gsr motor back in my hatch..i get atleast 300+ miles a week...would the motor be reliable...depends? right now i got a stock b16 motor in it...wondering if the motor would give up on me...

what are some bad things that can happend?..thanks.

 

how high is the compression??

 

around 12.1

 

The quality of the build, and the tuning will have more to do with reliability than will the static compression ratio.

 

im running 11.7 for my daily runs fine
