Alright, if anyone has any suggestions on a specific compression ratio that would be suitable for a JDM integra type R going turbo I would like to hear your thoughts.... Also keep in mind that reliabilty and streetability are a major concern as I can't afford to blow a $4000 dollar motor!! Anyhow, I know of Gsr's on stock bottom ends that respond very well to boost and as of now I'm convinced that if I mimick the gsr's stock compression (using aftermarket pistons) I would get good results. However, I'm also told that even that high of a C/R which is I think around 10:1 would require me to run a very high octane fuel and this is not appealing to me. But, are there ways around this? Is it possible to tune other components to where I can safely run a 10:1 on pump gas? Let me know what you think!!!!
