Hi Guys...
I need some help please. I recently installed the 4JA1-L engine. There is a turbo/compensator fitted to it, but no intercooler.
I need a bit more power, especially on the uphill parts of our roads here in South-Africa.
Can I bolt on an intercooler to increase the power, and if so, would I then have to change the pistons and injector pump also?
Any advice please
