Potential of SOHC D16 All Motor

course one thing is that there was no mention of compression ratios or head work. If you're planning on building N/A SOHC I would reccomend using a higher compression piston and making sure the tolerance is very close. You have to be careful not to ram the valves into the pistons as that would be well...bad. I'm sure you know that already but I just put that there for those who don't. Also you may want to consider utilizing a bigger lobed cam and better head package. I have seen as much as 50 hp gained from just cams and proper tuning. I've been toying with the idea of building a 1.5 SOHC motor for a bit and have been doing some research, I think the largest compression piston that I can get to work is about 12:1 which is crazy. I did find that GUDE makes a head package that will perform to what I would need but on the same note Crower will regrind cams (as ALL their cams are regrinds) to my specs. Any how that's enough outta me for now.
