What turbo would be best?

as fred said>Fred answered 6 years ago well the stock mitsubishi 16g turbo would spool faster because i believe its smaller then the t3 t4. You probably will get more turbo lag out of the t3 t4 turbo BUT you will def get more power. I would suggest you just get a used 16g turbo for really cheap. You can iron out all of the bug your gonna face when that motor responds to the boost. Then when you have had experience with tuning and knowing the fuel to air ratios and know what is actually going on with your motor your should upgrade to a bigger one. That being said i dont know how much power a 4g64 motor can take before you will have to upgrade the iternals. I have a 2004 lancer with a 4g64 and its a dog i havent put any money into because im saving for something better like a wrx/sti or an Evo. But good luck if you need to know anything more go to evolutionm.net that is the best site to visit for mitsu questions because people on there have already boosted OZ rallys.
