[pete-stevers]

I am slowly working towards my coversion (IMG:http://www.914world.com/bbs2/html/emoticons/rocking nana.gif) ....I have a 3.0(stock) and hope to mate it to a 901 that bone stock....This car will be a street car and i am sure the 901 will handle the torque..but...what about the gear ratios...will first be to low? how about 2nd,3rd and so on... what is a 904 main? should I be looking for one??? how about recomendations on a LSD? do i need one (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

5th is too short. The engine will be turning some serious RPM's with 50 series tires. I suggest a taller 4th+5th. I wouldnt worry about the tranny with a stock 3.0 unless you do burnouts with it. It wont last 100k miles... but it will last for awhile.

The 904 mainshaft has a removable 2nd gear (unlike the stock 914 mainshaft) I wouldnt be too concerned about it. They are typically pricey.

Be very careful with what you spend on the 901. By the time you are done you could have had a 915 with stock gears configured for mid-engine. I get a lot of people with 5k in their 901's... it would have been cheaper to do a 915 (which is what the 3.0 was mated to in the 911)
