VAG VR6 engine + tranny viable?

[Frank818]

Speedy (and anyone else willing to help), I got my beer, I got my vodka, I'm ready. loll

So here's the list FFR says you need these parts from the donor:

• Front spindles with full brakes and front lower control arms
• Rear spindles with brakes and e-brake handle/cables
• Steering rack, tie rod ends, and upper steering column assembly
• Pedal box and throttle pedal
• Master cylinder and brake booster, and clutch master cylinder
• Engine with turbo and intercooler (if WRX model)
• Exhaust manifolds, O2 sensors, and down tube
• Transmission
• Rear lower control arms, toe links, and CV joints
• Front seats, front seat belts, and gauge pod
• Fuel pump
• Radiator
• Wheels and tires
• Door hinges, front w/ latches,strikers, and inside door handles
• Side view mirrors, left and right
• Rear view mirror
• Rear seat belts


Detailed covering (solutions):

• Front spindles with full brakes and front lower control arms
1- I would still use Subaru.
2- Retrofit the VW front brakes and spindles but unlikely the control arm.

• Rear spindles with brakes and e-brake handle/cables
1- Retrofit VW rear brakes and spindles + e-brake.
2- Retrofit VW rear stuff and upgrade rotor size and calipers.
3- Retrofit VW front brakes (12.3" for me), calipers, spindles and control arm (if that one is possible).
4- Use Subaru stuff but keep the VW e-brake.
5- Use VW front brakes (12.3" for me) in the rear and buy FFR 80656 - Wilwood 12” Front Brakes, Black Calipers, Slotted ($999 +$65 S S/H) for the front

• Steering rack, tie rod ends, and upper steering column assembly
????

• Pedal box and throttle pedal
I guess VW ones can be used, may require fabrication and certainly increase throttle cable length (mine is cable).

• Master cylinder and brake booster, and clutch master cylinder
With the VW pedal box, I believe it would fit.

• Engine with turbo and intercooler (if WRX model)
Use VW's engine.

• Exhaust manifolds, O2 sensors, and down tube
Use VW's stuff.

• Transmission
Use VW's stuff.

• Rear lower control arms, toe links, and CV joints
1- Use VW stuff.
2- Use VW CVs and Subaru for the control arm and toe links (that's feasible??).
3- Use all Subaru's.

• Front seats, front seat belts, and gauge pod
Use VW's.

• Fuel pump
Use VW's.

• Radiator
Use VW's.

• Wheels and tires
Depends what you got.
In my case I will re-use my tires for the front (and will have 2 spare), but need 4 rims and 2 rear tires.

• Door hinges, front w/ latches,strikers, and inside door handles
1- Use VW's.
2- Use Subaru's.

• Side view mirrors, left and right
Use VW's.

• Rear view mirror
Use VW's.

• Rear seat belts
Use VW's (whether front of rear).


So how can we get "quite sure" about these solutions? I mean, the question to ask at every bullet point is "what could go wrong?".
