Fitment

Other Gen 1 3.6L vehicles (for example Grand Caravan, Town & Country, Journey, Durango, ProMaster): choose "Other Gen 1" and send us your VIN. The engine fits many applications; what differs between vehicles is the timing cover, oil pan and oil pickup tube.

Confirm your engine

• Gen 1 only: this build is for the Gen 1 Pentastar (10.2:1 compression, no variable valve lift). Some 2016-2017 vehicles (for example Grand Cherokee and Durango) may have either the Gen 1 or Gen 2 engine. Send us your VIN.
• VIN 8th digit: G. Gen 1 and Gen 2 Pentastars both use G, so the VIN code alone doesn't tell them apart. Confirm by model year, and send us your VIN for overlap years.
• Not sure? Choose "Not sure" in the dropdown and call 623-204-6365 or put notes on the order.

Send us your VIN with your order to confirm fitment.

Notes

• Factory nodular-iron crankshaft, machined and polished. Rotating assembly checked on our balancer.
• Factory camshafts and cam phasers.
• Cylinder heads are not ported or polished.
• In-house seat pinning to prevent valve seat fallout (a common Pentastar problem).

Not covered

• Gen 2 (upgraded) 3.6L Pentastar with variable valve lift (2016 and newer applications such as Wrangler JL, Gladiator, Pacifica): not offered
• 3.2L Pentastar
• Stock (non-boost) Gen 1 3.6L: see our stock listing below

Built for boost

Intended for intercooled supercharger or turbo kits at typical kit boost levels, up to about 12 psi. Power depends on your kit, fuel and tune. We don't publish a horsepower rating. Results vary with tune, fuel, gearing and supporting mods.

Piston / rod kits

Both kits use standard 96 mm bore pistons.

Photos show the optional Prodigy kit; standard build uses the MMX forged piston and rod kit.

Every build includes

• Forged pistons and forged connecting rods (MMX or Prodigy kit)
• Factory crankshaft, rotating assembly checked on our balancer
• ARP head studs
• Cometic MLS head gaskets
• Pentastar oil cooler upgrade (all-metal aluminum housing)

Required / recommended

• Tune required. Boost needs a custom calibration. We do not tune.
• Intercooled kits only, at about 12 psi or less. Keep the tune conservative on ignition timing; knock (detonation) destroys boosted engines.
• Fuel: 91+ octane. Larger fuel injectors as your kit or tuner specifies. The factory fuel system has limits at higher boost.
• Monitor air-fuel ratio, knock and, if possible, exhaust gas temperature.
• Oil: keep the level full and use the oil grade your kit or tuner specifies.
• Cooling: the radiator, fan, thermostat and water pump must be in good condition.
• Driveline: your transmission and axles may not be rated for boosted torque. For reference, the 8-speed automatic (8HP45) is rated at 332 lb-ft of engine torque and the Wrangler JK 6-speed manual (NSG370) at 272 lb-ft.
• No boost during break-in.
