It could just be me, but why would you run a turbo that small and a supercharger that big, it's back to front.

No idea, but the fact that there's no intercooler just means by the time the already hot air gets to the supercharger and gets even hotter, the turbo will have a nice time...

That engine is going to die so soon.

Its prob running on methanol and has some sort of water injection to compensate for no FMIC.

The turbo is only feeding from 2 cyclinders also so it would be slow to spool up.

That said, they are americans so who know whats they were thinking!!

a few points i noticed:

1. blower looks like an eaton M90 or M112 lysholm type.

2. that's a big enough twin-screw on a little 4cyl honda on its own, let alone twincharging it like that.

3. no aftercooler between the system and the engine = ridiculous intake temps, it must run meth or C16.

4. maybe the turbo has a large a/r exhaust housing, the main reasons to twin charge like this are to spool up a large turbo very quickly, and to keep intake pressures above exhaust back pressure, so the theory is you can run a larger snail for a smaller engine, with no real drawbacks.

all in all, a very strange looking twincharge, but the principles are the same as my setup.

perhaps there's a water/air intercooler between the blower outlet and the inlet ports on the head? they don't have to be large in volume and can be packed with icy water for quick track sprints. i like the remote-drive they set up for the eaton there, very innovative.

      There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)

      What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).

      Custom titanium intake

      No I got mine from a friend that had fabricated one … but I had to fit it to my setup which was a hks turbo setup. His was a Garrett -7. So one of my turbos was not a flange for one side … then I had a leak in the welds I had to find a weld shut … in the end the setup was decent priced but I spent a lot to get it fitted. A couple companies I checked would make it but you’re talking 7-9k aud with titanium. No joke mine was 6-7k even second hand after I had to fit it in Hong Kong … labour is expensive here.

      I'd just like to restate that I don't think anyone here is actually hating I recently sold a car part to a guy who was building a forged auto R34, with MV stall and aiming at ~450kw. I told him that I'm him, from the future and to stop after it explodes once. I told him I knew he won't listen the first time, and that's fine. But if my predictions do come true - Change direction faster than I did. I also said it's probably no coincidence that the dyno plot of a reliable turbo engine starts to look a lot like a N/A motor. :p
