Its been some time, I decided instead of doing just an exhaust and intake that I would do headwork as well. I also replaced the OEM ECU with an Emtron SL6. I needed another excuse to keep practicing tuning, its just such a joy.
Full head, STOCK bottom end (OEM Pistons .50mm overbore, OEM rods, OEM crankshaft, OEM 1.1mm head gasket), STOCK Intake manifold and Throttle Body from GEN 2 1FZ-FE.
I would consider this a mild setup with a somewhat of an aggressive cam. It is still night and day from what it was stock, great power from the start all the way to a red line of 6000 RPM, even though it has decent torque down low you can really feel the powerband above 3000 RPM, you can feel the front end climb as it revs up gaining more and more HP. Whats great is that it does not sacrifice bottom end power and it feels more potent during part throttle and transient conditions. It dropped 3+ seconds 0-60 MPH, pretty good.
