Thread: interested in your opions 86-88-90mm bores

Ok so imagine if you will you built 3 identical motors .. same everything EXCEPT bore .. 1 is 86mm 1 is 88mm and 1 is 90mm how do you think the power would differ between the 3? Basically I am just curious and trying to decide which route I should go. My main issue with larger than stock bore is simply I dont know of anyone in my area I can trust to do the machine work lol. And sending it off is really my only option as of right now .. I am planning to explore the situation more amd see if anyone in the area has experience with sr20s but incase I cant im just looking at other options just in case .. so lets hear your guys thoughts about this bore vs hp debacle.

My first thought is about 10whp between each bore size.

Hmm you think its really that much difference with just 2mm extra bore? If thats the case seems like at the very least I need to find someone to punch her out to 88mm lol
