Have a 1990 4runner 4x4 that is almost ready for a wiring harness and tune. My question is what to expect from the installed K26 (Audi application) or if I should be looking at changing a few bits. Turbo is in good condition and is fed water/oil. A/a intercooled, engine size is 2.4L, 8.5:1, manual trans. One opinion is that it will have lag but good in upper rpm's- I'm thinking idle through 5500 should be good for me.
