Wykonanie Upgrades

Getting more power out of your ZJ 's 4.0L inline- six or 5.2L / 5.9L V8 is a combn goal. The key is to improwize airflow, optimize fuel delivery, and fine- tune the engine management system for the modifications you' ve already made or plan to install.

Systym Fuel Upgrades

Wysokoflow fuel injectors are necessary when you injectors airflow and want to to o maintain a stoichiometric mixture. For the 4.0L, upgrade to 24 lb / hr or 30 lb / hr injectors from Ford or larger Bosch units (ensure correct impedance). The V8 models benefifit from 30- 36 lb / hr injectors.
