dgoodhue Posted August 21, 2013 Share Posted August 21, 2013 Have you ever looked under the hood of his car and look at his supercharger? Link to comment Share on other sites More sharing options...
subsub Posted August 21, 2013 Author Share Posted August 21, 2013 Of course And you? Tell me what you think about it. Link to comment Share on other sites More sharing options...
dgoodhue Posted August 21, 2013 Share Posted August 21, 2013 The 3800 has a roots style supercharger that is integrated into the v6 intake manifold. I would buy your Grandfather's Buick GS. Park your Legacy about 100ft away and set the park braking. Get into your Grandpa's Buick and drive it full speed forward into the front of your Legacy. It will be the closest your 2.5i engine will ever to having a supercharger off of a 3800 V6 Even if you threw both cars away and bought a Legacy GT, you would ahead of the game and the cost of re-engineering a 3800 v6 intake manifold and supercharger in order to make it fit a Subaru H4 motor.

JermTheElf Posted August 21, 2013 Share Posted August 21, 2013 It should work, just make sure you buy the apppropriate gaskets. Don't listen to the nay sayers up above, they don't know wither platform well. It doesn't take an engineer to see that there is clearly space to do so. You will have to cut away a bit, and you'll probably need the GT hood but that would be an upgrade. The carbon fiber is a great upgrade in itself.

pleaidestar Posted August 21, 2013 Share Posted August 21, 2013 Check out 1055's supercharger build, its a different super charger but you know there will be some info you will need. Link to comment Share on other sites More sharing options...

You will have to cut away a bit, and you'll probably need the GT hood but that would be an upgrade. The carbon fiber is a great upgrade in itself. Just different gaskets? Haha, try an entirely new, totally custom intake manifold. A LGT hood won't give room for the SC. The opening is behind the intake manifold completely, since it is made to direct air through the intercooler that would sit there. Not to mention the neck of the SC that has to extend out to be in line with the belts. There isn't a lot of vertical clearance under the hood. Sure, anything is possible with an endless supply of money, but it doesn't take an engineer to to see that it would clearly be very difficult and who knows how expensive.

subsub Posted August 22, 2013 Author Share Posted August 22, 2013 I tought of placing it instead of the air intake box and rerouting all the wires and tube there And installing a sort of turbo piping to connect it to the trottle body... And putting the air filter in the fender The thing i want to know is do i need to change injectors, rod and that kind of stuff? Link to comment Share on other sites More sharing options...
pleaidestar Posted August 22, 2013 Share Posted August 22, 2013 I'm sure that's rule of thumb replacing the stock rods and pistons for strength and using internals for a lower compression ratio for sc'ing as it is with adding a turbo. Unless your tuning for under 9psi I cant see why you would go through the trouble and cash for something so tame. Link to comment Share on other sites More sharing options...
EJ25subie05 Posted August 22, 2013 Share Posted August 22, 2013 why???? Just get a LGT and build that instead... all that work and its going to look and run like CRAP!!!!!

If you had any experience with supercharging a legacy you'd know better. Do some research. Link to comment Share on other sites More sharing options...

ResidentRedneck Posted August 28, 2013 Share Posted August 28, 2013 theres a fine line between being different and being stupid. being different is putting a supercharger on a 2.5i legg. being stupid is trying to make something work without weighing your options. "i want to supercharge my legacy. let me look at all possible options, compare different types of superchargers and systems to my mechanical abilities, and draw a conclusion." then theres you... "granpas got a supercharger on his buick, so i wanna put that exact supercharger on my car. because hell, i already got it, and it shouldnt be that hard."
