If your plans are toward boost my next move would be those engine mounts. Reason...



My '95 mounts were rests. They came out looking like that. Nothing attaching the engine to the frame. You are on a different path with your build so I would not suggest the 70Ds. But if you are going boosted the hybrid or the Mazda speed.

Keep up the great work and hope we all get to where we want!

Side note: Are you planning on a 'Palooza trip? Would love to shake hands with you!
