Hi all

I have a KE70 with a 20v silver top stock standard engine. iam wanting to do a nice N/A setup for time trials/hill climbs and a little bit of drifting i have heard that the black top is more suited for a N/A setup with the higher compression and bigger intake port but i have heard that the crank and rods aren't as strong as the silver top. so iam wondering if it would be worth changing to a black top or keep the silver top.

I don't know the details of the differences, but there's always a strong argument for sticking to plan A.

 

You have the silvertop so fit it, then modify or change it further down the track once you have had some fun and decided how much more money you want to put into the project.

yea i don't think the black top is going to be much of a gain in the long run still going to be fun either way.
