not big at all, actually the calmest smallest build in 3 years.

going to go from the dual walbro 255s to a single bosch 044 fuel pump.
Switch to a TRD 160 thermostat, Switch to better dual fan setup and a DIF fan controller.
Upgrade to Q45 Brake calipers (already have them) Stainless steel brake lines, new pads and rotors.
And hopefully switching over to a AEM EMS V2.
