[S54life]

I hear that big engines in 2wd cars will just spin but what if I run a long hear for engines. What's a good setup for gearing and where can I if can get parts for the old sportsline

4 bolt is heaps more reliable.

Go with the 30.5 just get big gearing 26/38, and atleast a 16/48 in the back im waiting for gears to try 18/46 on the diff, i run a 30.5 fully modded and ported, its actually modded alot more then the obr but obr makes amazing engines you cant go wrong ! With the 30.5 you could still have the fast acceleration and top speed you have alot more options it just comes down to changing the gearing ?
