I called a guy for an engine and he told me i can only put a 3.2 in it cuz it's 99 and they didn't have the 3.5 in those cars at the time. He also told me it's gonna cost 3000 just for the engine then there's the labour and extra parts and fluids, which is when i hung up on him. Is he right about the 3.5 not fitting in perfectly without changing the mounts and all that?
Did you went on the link I gave you earlier???
This is what you need:
3.5/2L Parts needed:
- Motor Mounts
- ECU/PCM (not required to run the car. SKIM ECUs will NOT work. Only 3.5L non-SKIM ECUs are R/T). 3.2 and 3.5L fuel/ignition curves are slightly different, but one ECU will run the other.(Must be 98-01 if you have a 98-01. Must be 02+ if you have a 02+)
- Exhaust Manifolds
- Intake Ducting/Airbox or Aftermarket Intake for 3.2/5
- Heater/Radiator Hoses
- Oil Cooler and Lines
- Engine Wiring Harness (Must be 98-01 if you have a 98-01. Must be 02+ if you have a 02+)
- Alternator
- Power Steering Pump
- Power Steering Lines (?)
- Power Steering Reservoir
- 2.7L Downpipes Must Be Cut ~2" (see threads)
- 3.2/5 Throttle Cable (?)
The only real difference between the 3.5L and 3.2L is the power output and the displacement. The 3.5L alt will bolt up to a 3.2L and etc.
FAQ:
Is the transmission different?
No. It just has a different gear ratio. You do not need to replace it.
Does the TCM have to be replaced?
No. Infact you should keep the 2.7L TCM because of the gear ratio difference.
Why must I stick to 98-01 ECUs/Wiring, or 02+ ECUs/Wiring?
The wiring and ECU changed greatly in 2002. If you have a 2002, you have a larger ECU that works as a TCM as well. The 98-01s have seperate TCMs. Because of this, the harnesses are different. But you can put a 98 engine in a 02 car, and vise versa.
