Speedbuggy

whoops, just noticed I put this thread in the wrong section! Any mods want to move it to the tech area? Thanks for the info Gary, I'll search for a comparison.

My buggy currently does not have a thermostat in it (the engine was built by Outfront motorsports and they specialize in sandrail applications where they don't recommend running one). I want to go ahead and install one, but what is the factory thermostat temperature? What other options are available? I'd like something around 180 (edit,.. I'm thinking lower now actually 150 maybe if possible).

Olnick, when you're pasting the address to the image where are you copying it from?

Wow, really? They've always been great for me for my various Chrysler cars. Are they really that bad for Subarus?

Finally, that one is much clearer. Thanks for your help everyone. Also, where can I find the rest of this collection you refer too?

OK, I found this online, but it's still not exaclty clear what happens when the thermostat changes state. If someone could shed some light on that that would be great.

Wouldn't that damage the waterpump?

ej25d.

Thanks for the link... Seems to be a lot of confusion in this area! Unfortunately the links in that thread are all dead. But so far I've learned that the coolant flows bottom to top of engine and top to bottom of radiator.

Not really..other than confirming that's where the water pump is.. but where does it go after leaving the engine and does it leave from the top or bottom? How does the route differ between a closed or open thermostat?

Hi, can someone find a typical coolant flow diagram for me (or at least break it down for me in text)? Something that shows the typical direction of flow, and in what order everything is in? The coolant system is a bit different on my buggy so I'm trying to figure out what the factory set up was as a point of reference. I'm coming from the air-cooled VW world, so I'm unfamiliar with this stuff!

The only technical details I know about it are that it's running a Turbonetics T3/T4 around 8psi. The fuel injectors are low impedance bosch and it's controlled by an EMS Stinger ECU. I know the fuel rails are custom and I beleive the intake manifold has been reversed on it to facilitate the rear installation.\ The transaxle is a sooped up Volkswagen Beetle unit with Porsche 930 axles and CVs. Oh and I should point out that the numbers I've been quoting are all from the previous owner. He purchased the engine as a 300hp but I don't know if it was ever tested an on engine dyno. Does anyone know a good place to take it within 4 hours or so of Pittsburgh, Pa?

Interesting.. sounds like I need to get it to a tuner sooon.

Certainly not a stock tranny.. it's a supped up VW Beetle transaxle.

That's 220rwhp. The engine dyno'd on an engine dyno at 300. Those number's don't sound right? What's the boost levels on a stock STI? I believe I'm currently running about 8lbs. Then again, it scares me with it's current performance, I'm not sure I'd WANT more power!

Thanks for the replies guys. Weird, my google fu must not be what I thought it was. IT looked like most STIs had the 2.0. As for video, there isn't any at the moment, but I'll make one soon! And as for performance, this buggy dyno'd at 220hp at the rear wheel and weighs only 1900lbs. Oh and now that we've established that it's basically an STI engine, what is the factory redline? This buggy has autometer gauges so I have no idea what the redline should be. Seems like it starts to lose power around 6300rpm, just going off the seat of my pants.

Was the EJ25 ever in a WRX STi? The company who built my engine (Outfront Motorsports) claim that is was built on a crate STi shortblock, but it says EJ25 right on it. In the bit of research I've done it doesn't appear that the EJ25 was ever in the STi. Others on here have told me it's an EJ25D based on the picture below, so i'm just trying to figure out why the company who built it is claiming it's from an STi shortblock.

Hehe.. thanks!

My last buggy ran a standard Volkswagen Beetle engine. The body itself is all fiberglass. There is also a complete rollcage with side intrusion bars incorporated on both sides. The body is from a company called Meyers manx and can be found here: http://www.meyersmanx.com

Surprisingly I don't recognize either last name. But I guess it's not to surprising, I didn't go to school here, but just across the border in East Palestine, OH.. So back to the engine.. it's an EJ25D.. Other than making sure I never let the timing belt wear out, what other stuff should I watch for? I've read about the head gaskets, but this engine was completely rebuilt by Outfront Motosports and so I feel confident they replaced the head gasket already.

Thanks Murph. Yeah the guy that built it did a phenomenal job. He actually runs a business doing it. This particular one was his personal car and he also used it as a show model to sell more. I jumped at the chance to buy it as I got a great deal. This is his website: http://www.denmatcars.com/ My car is the Manxter 2+2 TS-300. You can see what he charges for a brand new made to order build on there. I didn't pay anything near that (since I bought his personal car that he'd been using for 4 years) but it will at least give you an idea. There's another company out of California that builds them too and they have a wider range of models from a good bit less to a good bit more than what Denmat offers. http://mendeolamotors.com/motors/ And of course, if you're so inclined you can get one much cheaper by building it yourself: http://www.meyersmanx.com/manxter2+2.shtml

Yep, that's about right!

Ahh, yes I didn't pick up on the Amish tie-in.. I should have considering my Dad grew up Amish! What's your buddies last name?
