I'd say go 5.29's and rebuild your engine with a good cam, header, intake. Just from my header I put on mine I noticed a nice improvement on a very worn out 22re (250,000) Personally I wouldn't change my gears to anything higher than a 5.29 with the stock 4 cyl. power. now if I had a v8 or something I'd consider those higher gears just my 2cents
