That's about right, 3rd gear @ 5000 says 112, which is where it usually traps 110-112 area.

So a 3.73 would be right about 5500 rpm?
and 3.90 about 5900?

I'd stick with 3.73. More than that is a lot of gear for highway cruising

You want to go across the traps pretty close to the rev limiter or where your car makes peek power.

3.90's would work well IMO. But if you plan on going faster you will either need to raise the limiter or spin the motor.

I was wanting to try 3.90's with my bolt on car but didn't get around to it before the turbo build.

I had 3.73's and was happy with them tho.

For now I want to make the most with what I have engine wise. So some gears and a converter will aid in that.

If I get some low 12s I'll be fine for now. My car shifts right about 6500 right now, so I don't want to raise it any more

Got my converter in, have not driven it yet.

Will get some track times on the 20th weather pending...
