I am getting ready to make a custom cluster out of a spare. Replacing Speedo and aux gauges with digital and trying to find a new tach. Future plans are to rebuild the SR to make it stronger. How high can I expect to rev a build SR, so I know what RPM tachs I should be looking at? Planning to Open Road Race if that helps.

Thanks,

S14 w/ redtop SR

 

usually not much more than 7,750. but if you are a psycho like me you'll build one to spin to 8,500

 

hell, the japanese regularly take the drift s13's to 8500 with just valvetrain and ras.

but alot of them use the s14/s15 sr's which have stronger oilpumps.

then there'st he drag sr crazy people with 10k -11k motors

and the non turbo guys and the primeras of the mid to late 90s competing in the btcc turned around 9-10 also.

keep in mind as the rpm increases the cost to keep it together increases exponentially.

 

now when you say 7,750, is that on a stock SR? and to build one to go to higher rpm's what do you do to achieve thouse goals? just work the valve train?? or do you also have to work the bottom end?
