Do some research before you buy the motor because to my knowledge, the 2.4's use direct injection and throttle by wire, and that is a whole can of worms as far as getting it to run in a buggy.

I did some research and I went with an Ecotec (2.2 150hp version). The suby needs a modified oil pan (and even then, it hangs down low) and has coolant hoses coming out of the bottom of the motor (doesn't sound like a good idea in the woods). The Ecotec is 21" long, which is the same length as a bug motor with off-road exhaust. Its heavier than a VW, but makes 3 times the HP too.

And the Suby 3.3 flat 6? Sure, its novel and sounds neat, but those motors were only made for a couple of years, you NEVER see an SVX on the street, parts are expensive, and Honda 3.5 V6 that make 250hp are EVERYWHERE for $600 for a complete motor.

I have the electronic throttle assembly and Sinister can do the programming.

Here is a site I have used a few times it is a list of actual engine weights

I think everyone has forgotten one important limiting factor. At some point the power your taliking about will begin to break transmisions, it's not a matter of if, but when. In my opinion, a stock 6 rib won't handle 150hp for very long let alone 250hp. Even with a super diff and all Weddled up, my mind tells me 250hp is beyond the limit of what it will tollerate. I went with a Subie because I knew the transmision, properly done (thanx Roy) will handle the 130hp and it has for the last 4 years. Same clutch, CV's, axles all 4 years old.
Something you'll need to think about, or start buying up 6 ribs, your going to need them.

just looked over this thread. I don't know anything about the Ecotec's, but know a little too much about the subarus.


one thing to keep in mind. SVXs are big, heavy cars with very torquey motors. transmission failure is VERY common. Also, they're very unique and rare, so other parts are valuable.

I know of a few guys who were able to buy a complete car with a failed or failing trans for less than a grand. keep the engine, wiring, ECU, etc., Sell the fenders, doors, interior, glass (lots of curved stuff, very hard to find!), and make a couple grand or more! depending on how actively you try to sell them.

I did the wiring for a guy who put an EG33 in his 2001 2.5RS. he paid me to drive across the state, put me and my girlfriend up in a hotel for 2 nights, paid me for about 20 hours of labor (lots of custom stuff....not a straightforward swap. but it'll be worth it), and still came out about a grand up. That's right, engine swap, paying for quite a bit of labor, custom radiator, and a few other not-cheap items.....with cash left over!



Also, 2.2 non-turbo motors are cheap, and bullet-proof. and the logic modules that control the fueling in the ECU are incredibly smart. able to correct for a 5-7psi of forced induction quite reliably. I know of a guy pushing 12psi daily through his 2.2 with injectors, and a higher fuel-pressure regulator.

And there are a few of us putting superchargers on them. I'm using an Eaton M62 off a 2000 Mercedes C230 Kompressor. it's design allows pretty simple mounting without having to integrate it into the intake manifold. and it also has an electromagnetic clutch in the pulley, just like an A/C compressor, that entirely eliminates parasitic loss off-boost. I'll be running it with a Link fully tunable ECU. stock pulleys should yield about 4psi, and almost 150 awhp (consider almost 20% drivetrain loss too). with a larger crank pulley, the rest of my setup shouldn't have trouble hitting 200 reliably at about 8 psi. and this is all at 9.5:1 compression (stock N/A '93 2.2l that I bought for $100, then rebuilt for about 300).

I agree and I have been seriously considering updating my transmission to accommodate the power. I must point out that I will max out at around 185 to 190 hp in the configuration I plan to run and not the 250 you speak of. I have also taken into consideration the type of running I plan to do. I have a family of five that I must look out for and do not plan on beating the live crap out of the buggy. I also know there will be a time when I am in a jam and will hit the throttle to get me out and at this point in time I will run the risk of trashing the tranny. There are no givens in the buggy world only calculated risks. I have 930's, large axels, and a 6 rib that should hold up to most of what I throw at it. I have been running a 3 rib with bus cv joints powered by a 2276 fairly hard and have not had a problem so I am willing to run this set up with some confidence, but with some preservation on the throttle.

Found these pictures of an ecotec swap. Thought they may be of intrest.

WOW that nice what is the weight of the motor

_________________
drive it like you know how too fix it

It weighs about 300 lbs with the radiator and water. Nice pics of the install, where did you find them? I do like the exhaust system they put on.

NE link to that post of this pics? I want to know where he got that exhaust header!

Most of that stuff is custom made. I'm making a set for my Subie out of stainless steel.
Here is a link for mandrel bent tube and header parts

Sorry i looked again but i cant find the sight. I do remember that it said he bought mtr,ecm,harness,and header from a supplier that also supplied gm ls1 v8 kits for buggys. Catering to sand guys i'm sure.

after extensive searching I found the site and post. The engine and everything was from turnkey. This guy did this ecotec swap way back in 06' allready!

Heres the link if anyone wants to look over the pics.

Even better [/quote]

Was there any progress to this? I did see in the tranny forum someone was asking for a list of tranny builders.
