Max Si rpm

[survivor182]

What s the max rpm can the SI usdm engine can theorictly handle? (with the 7100 cut-off eliminate)

7500?
7800?

well, I used to rev to 8700-9000 when I was drag racing my SOHC motor. I only did pistons, stock rods and tons of mods, but it would pull the whole way up! I'd go 8000 at least for street use if you can get the rev limiter removed.

personally, my Si hangs 7500-ish. but, don't quote me! every Si is different depending on wear & tear. mine is an '89 with 115,000 miles

I'd keep it under 7500, the rods on a D16a6 are very small and weak, it'd be easy to blow your motor without some low end work
