Ok, I am knee deep in planning, and after riding in a turbo 2.0, I found myself wanting much more power from the engine. I know I could build up a ecotec, but that can get expensive. The 2.8 with a turbo upgrade and a tune can make 450-550 rwhp on the stock block. Also, the weight difference between an LNF and the 2.8 is pretty minimal. All that aside, technically if this were to work, you could put any HFE or possibly LFX engine in a goblin.
Now that the why is covered, I want to go over if. Assuming since it came out of a 9-3, I don't see why it wouldn't generally wouldn't bolt into a goblin frame. I know there may be some dimensional issues being a V style engine and of course the recently talked about fitting the F40 transmission. I am completely ready, able and anticipating some modification to fit it all in there. I spent some time looking at RRtoy's goblin this weekend and I think that the accessories may need to be moved around alittle, but otherwise should fit without issue since the ecotec is not a vertical engine and is at an angle already with the accessories and supercharger in his case filling the void where I assume the other bank of the V would fill. SO, width wise I don't see an issue as a V6 should actually be shorter than a 4 cylinder, length wise I think it will be as simple as routing accessories, plumbing and anything that may interfere with the turbo. and height I think should be no issue.
Onto Electronics, how realistic is it to run a cobalt BSM with a saab ECM? Assuming that would work, that would solve all the issues with the swap and I could just use a cobalt donor for everything but the engine. Assuming that wouldn't work, that would take me down a rabbit hole where I would likely ditch the cobalt electric steering, adapt a miata depowered steering rack, fab up a miata to cobalt steering rack adapter and just run no BSM with autometer style gauges.
PLEASE feel free to fill in the gaps in this theory
PS the V6 turbo exhaust sounds amazing
