Properly built SOHC...nice car

K20 I think is the way to go but whatever floats your boat

LOL i thought about K20.

I decided I wanted boost over NA for the time being. Someday I'll make an All motor K20 when it gets a little cheaper.

22.68 - 23.00 is the standard tire size range.. 3000rpm = 70-75mph.


I used 23" slicks during my dragstrip events.

well, just running the math, you'd be going about 64.4 mph at 3000 rpm if your tire diameter was 23". That seems like a reasonable, cruising speed for a four cylinder and I personally wouldn't go any shorter on the gearing. I hope your speedo isn't telling you 75mph at 3000 rpm. Then again, that could keep you out of trouble

(3000rpm/.75*4.25)*(23in*pi)*(60)/(5280*12)=64.39984941 mph

It's pretty simple; I just used your gear ratios to figure out the rpm at the front wheel and then I converted that into inches per minute using your tire diamater. Lastly, inches per minute is converted into mph.

the speedo has RPM division by every 500rpm so its hard to tell 3200 from 3100rpm.

If anything, its around 75mph or so under 3500rpm which is reasonable.




I just bought new parts to rebuild my transmission with an LSD differential so I don't have to do stupid peg legs anymore.
