4.10 vs 4.3 in 20B N/A FC

I edited my first post because I wasn't sure if we are talking about the same thing. The stock n/a 4.33 rear end is coming out for sure. I bought a 90 TII to go in. The TII rear has 85,000 miles and is getting a good check tomorrow. I was saying I might just keep the TII stock diff in and see how it goes. If I upgrade I was thinking about the Guru Torque Biasing Differential.

As for the R&P I was probably getting Mazdatrix. Racing Beat's is 525.00. I haven't spoke to Mazdatrix yet. Their website is getting upgraded or something and don't know the price yet. I have dealt a lot more with Mazdatrix.

Thanks Roen, that formula puts in a more tangible perspective. I think the 4.3 is what I want.
