How long should a Bseries last for if it is high compresson. Lets say its in between 13:0:1 and 14:0:1 on 110octane and w/440cc inj not daily driven. Or would the motor have to be rebuilt every year. Thinking of building a motor up but i want good power. I d say it would probly see 4,000 miles a year.

Thanks in advance for the info

in racing it's hard to say how long a motor will last it may last a week or it may last 10 years. it all depends on the tune and how rough you are on the motor and if you take care of the motor

 

I don't beat on it much. When i do take it out i hit vtec 4 to 5 times.

still very hard to tell your motors lift span
