Hey guys,
After a great discussion with some of you I have decided that my future build will most likely be a 2.3L stroker with 9:1 compression mated to a Evo316g turbo or maybe a Borg Warner turbo. Discussion Here
Goals for this build are maximum torque across as much powerband as possible with 7k rpm limit. Should be a fun street car /ubbthreads/images/graemlins/smile.gif
Now for my problem:
I had a 2.3l from Magnus in the past. Loved the power (don't remember the CR), but hated the second hand harmonics that seem to vibrate every bolt on the car loose. This vibration was subtle in that you could barely feel it in cabin, but no sh*t - I was retightening bolts monthly or less. Yes I had a damper on it
I do not want this kind of vibration again! Reading the "To stroke or not" PDF file, I now know why I had vibration in that motor!
A lot of you guys are going to try to convince me that balance shafts are evil, power robbing, possibly engine grenading things. I hear you, but the 5 or so motors I built with BS's have survived over 50k miles with no issues at all. Please keep in mind these motors stay close to factory rev limits.
Have any of you (or any of you presently) had the balance shafts installed in their 2.3l stroker before? Do you feel any vibration or have any bolts loosening due to second hand harmonics?
Should I run 4g63 balance shafts or do I need to run 4g64 Balance shafts?
I plan to hopefully build this motor next year.
