Go for it, if you have the fabrication skills and the tools to get it done. The frame/subframe would need to be modified, new engine/transmission mounts made, rear suspension adapted and modded, fuel system figured out, wire harness reconfigured, along with a host of other things that are not Honda in a Goblin. Good luck and keep us posted on your progress.

Your 95% there, just a few things and it'll be done.

It's me, look who's talking! I'm just trying to make a car that runs, out of old stuff. Have you got enough Bridgeports for this job? I've got to say that putting a Honda motor in a vehicle that most folks won't even know what the heck the car IS could be a conversation piece. It might be faster with a Honda Motor?, but in the 0-60 sub 4 second category you're likely talking a 1/10th or two. ****(ranting?)We put a 51 Caddy 303? V8 backed up with a 47 Lincoln Zephyr 4 speed trans in a 54 Allard(GB), (but I think Allard had done that before). Several "JTR", small block Chevy/Jags + one fat motor. SBC's in everything(including one Pantera; that stroked 400 was way cheaper than finding and building him another 351 Cleveland). Chevy 502 out of this rich fella's Cigarette (offshore racing) boat(the standard rotation one; he sold the CCW one for some $$!) into his big old Rolls with a THM400 and a Gear Vendors O/D.(he might have been running drugs?) We put a 302 Ford in a 33 roadster with a 700R4. A Jag rear in a 77 Trans Am and one in a 73 Mustang conv. ALL of these cars(and one boat) had ONE obvious similarity, their owner's deep pockets! These cars were Their Dreams and I was just helping out.**** So, yeah, it can be done, the major factors(as always!), cubic dollars and adequate time. Have ya thought about S/C, T/C or twin turbos? Nitrous? Hayabusa? JATO rockets? Tesla power? or just a plain ol' P&W PT6A-67A(turbo prop)shaft turbine? I've got nothing against repowering a Goblin other than maybe why? BUT that is your choice. I'm willing to watch!

But really!, look long and hard at the SeriesII 3800 S/C motors! Plentiful in the yards and about the same dimensions(maybe shorter?) as an Eco-Tec. This is the child of the Buick Grand National Turbo 6. It's no slouch.

Just needing an adaptor kit, engine mounts, Intake/ exhaust. Computer, wiring, plumbing. Still, "I Like To Watch!" We're with ya Buddy! ****BTW, can anyone QUANTIFY for me what this "Honda K motor" stuff does that other motors don't. (Like maybe they only blow up 1/2 as often, but they also only cost 2X as much? =/= New Math!)

Custom subframes are not that difficult to create, if you have the fabrication skills. I've made one:
@Sebnuts has made one:
Believe there may be a few others created that have not been posted by other builders.

And there it is! Thanks for the splainin'. Now, once again, we shall see what we shall see! As I wrote, I've done less with more and visa versa. Like everything, there's gotta be some payoff at the end of all this. I'm having fun, I Sincerely Hope Y'all are as well!

The path of least resistance would probably be to run the Honda 6 speed with the k20/24. The K series is a fantastic motor, but the trans is less than fantastic. They're known to fail even at stock power, also making them somewhat expensive... Not sure how it compares to an F35/F23. However, because you're going to use it to power something that's half the weight of an 8th/9th gen civic the trans will probably hold up fine in a goblin, but you should probably open it up and replace the syncros at a minimum. Particularly the early 8th gen Si's had a lot of syncro issues. They're fluid-picky, so I've seen a couple "bad" transmissions get "fixed" with some amsoil MTF. With that said, the factory LSD in the Honda trans is surprisingly good for a factory LSD IMO. If you would like to mate a K your GM transmission... Miata's have an ecotec and K swap kit available... but I don't believe patterns are published. It might be a good start to get a rough idea on the differences, though.
