Compatible Donor
The only compatible donors are the Chevrolet Cobalt and the Pontiac G5.
Even cars built on similar platforms (Chevrolet HHR, Saturn Ion) are not 100% compatible because of slight differences throughout the donor car's equipment. Using these cars will require extra work to either fit the pieces that differ or to swap to Cobalt pieces.
Other makes of cars will be an even harder challenge to use because none of the donor pieces will fit the Goblin frame.
We reuse so many of the Cobalt pieces that if you swap donors, you'd have to rework the Goblin frame to fit those pieces.
We reuse more than just the engine and transmission so swapping to a different donor isn't as simple as just doing an engine swap. To give you an idea of what we reuse from the Cobalt, here's a list of the larger items:
- subframe
- control arms
- knuckles
- bearing hubs
- steering rack
- steering column
- pedal boxes
- brake master cylinder
- shifter assembly
- BCM and ECM (and TCM on automatic builds)
- ignition switch
- gauge panel
- fuel pump
If you don't use a Cobalt donor it'll be up to you to fit all of these pieces yourself.
