Anyone ever had any experience with the bolt on turbo kits from Japanese companies such as APEXi, Trust, GReddy, HKS? Most make kits for 4AGE to fit on AE86.
Any good, or better to go custom? Or better to swap a 4AGZE?
I know they generally are low blo (about 5psi) and no intercooler. Is it easy to up the boost on these with the standard piggy back computers they come with, or do you need additional fueling/new computer?
