New (old?) Idea.
Ok, so I'm still split between a turbocharger and a supercharger for my EG33 swapped wagon.
Supercharger is the current king of cheap though, so that's kinda where my focus has currently been. But the problem with just mounting it inside the intake has always been the lack of intercooling, and excessively high intake temps. soo.... WRX-ish TMIC (probably one of teh bigger ebay ones). Enlarge the "inlets" (now outlets) and run them to individual intake plenums, with runners that attach to the stock velocity stacks/injector jobbers. Basically, mount the intercooler facing the normal direction, but flow the air in reverse. My other idea was to do a panel filter on the non-supercharger side of the top of the motor ala: So that you could have a 2nd hoodscoop for the filter, and it would make throttle body routing and compressor bypass a bit easier to route. I should also mention I work in a CNC machine shop, so actually making brackets and plenums is relatively cheap (though time-consuming) for me. Also I have questions and ideas about the plenum volume, runner length, etc. And if you haven't realized it yet, I'm totally ripping this off, but with larger plenums and equal length runners, plus the EG would have more room on the drivers side top of the motor for the panel filter, and has COP instead of the IGN coils mounted there, so it's completely open: Thanks guys! |

Re: New (old?) Idea.
Very cool idea. The problem in the SVX engine bay actually is more the very tight space under the intake manifold for it to fit. Hence, the shadow machine, with it's big plenum sticking through the hood, and the very tight airflow angle that the ecutune manifold created. Seems to me that the other subaru engine bays have more room top-to-bottom, so you could fit a taller plenum.
Something like this was the best I had come up with though: http://www.sl-i.net/FORUM/viewtopic.php?p=160550 Your idea is much better, since it incorporates the TMIC.

I want to do dual plenums kinda like this: so that I can fit the supercharger between them with the outlet manifold dumping into the lower part of a WRX-ish intercooler. also, bought this yesterday for $75. 60,000 miles on it, no play. |

Re: New (old?) Idea.
A PD blower on this engine is the best way of improving performance.
But you must start with the engine as it is now, producing 220hp. In the past, to install the blower, the inlet manifold has been butchered and it is the inlet manifold that is the key to this engines power. 7lbs into the standard engine will net you 330hp. Change the inlet manifold, engine's output drops to 160hp, add 7psi to get 240hp. This is what happened with the ECU installation, I would fit the blower so that it blows into the standard manifold, to get the best results. Harvey.

Re: New (old?) Idea.
Is that an Eaton M62?

Processengr, it's an M90. I'd need twin M62's on an EG! which would allow you to retain the stock manifold if you could find room for all of that, but then you'd probably need a 12" cowl hood! |

Edit: the M62 was the series 1, looks like they upgraded it to a M90 later on. I always searched for the ford M90 because of the odd output on the GM versions of their chargers. The ford used a standard square outlet instead of the manifold style outlet with all the odd ports and odd flange setup. Last edited by Tireiron; 02-17-2013 at 12:06 PM. |

Re: New (old?) Idea.
Found this while looking up various S/C threads. Anyone know what intercooler that is (or at least the dimensions)?

Re: New (old?) Idea.
^ interesting find. got a link to that original thread?
Because the intercooler has two outlets matched to the TBs, it's probably either a one-off or modified one. It's possible to buy intercooler cores and then have the ends made for whatever your application is.

http://www.subaru-svx.net/forum/showthread.php?t=36097 Google says it's a Legacy built by JC Sports, and it's not around anymore. I still need to get my hands on a supercharger and an intercooler to see if it'll fit in the SVX engine like it does in that picture of the Legacy.
