Jay, Here are links to two quick sound clips of the car. One I revved while idling and the other I did a little drive by. Please excuse my wife's voice. Man...she cries for attention.

This is where I got my piping for my intercooler inlet/outlet. Cool guys! Nice to be able to drive down the street to them.

Yep!

I could see why you would imitate the TWE header. It's already been done and you know it works. I would think that it is pretty much equal length based on the sound alone. My car sounds nothing like anything 'boxer' like the Borla header does for the 2.5RS or even the WRXs. The sound is raspy, almost motorcycle like. My wife says it sounds like a motorcycle is coming down the street when I pull up. Maybe I should do some sound bytes so you know what I'm talking about. Here is a picture to help you get started. If you look close enough, you can tell it is not exactly equal length. It gets the job done though. Perhaps a tuned length header is possible if the drivers side exhaust pipe does not go towards the back but rather the front. I dunno. Space is tight either way. Good luck!

The wastegate opens at a pressure between 59 to 69 kPa (0.6 to 0.7 kg/cm2, 9 to 10psi), according to my factory service manual. *Reference* Page 90, Section 2-7....Fuel Injection System. The turbo itself is a VF7 model.

I've thought about this on two occasions and posted about it. http://www.ultimatesubaru.org/forum/showthread.php?t=25553&page=1&pp=10&highlight=Acura+Integra http://www.ultimatesubaru.org/forum/showthread.php?t=22070&highlight=Acura+Integra No-one seems to know how to go about this.

FUEL! You'll need to find a way to be able to provide extra fuel and keep decent drivability. Higher flowing fuel pump, fuel pressure regulator, fuel injectors and maybe even fuel filter (I dunno). You will probably be a happy camper once you get situated with the fuel. Getting extra air in and out is the easy part.

Not sure if this is the same turbo in this chart but does this help?

*I'm not trying to be an arse but* this is the thinking but it haven't been proven yet on our cars. Has anyone shown this to be the case?

Hey all, I was reading an email that Gary Gross sent me about how easy it was to install an MSD fuel pump on his XT6. This same fuel pump I have on one of my XT6s but I didn't see how it was installed. I just purchased it and had it installed, not knowing the modifications involved. Gary said the fitment of this pump in the XT6s place was excellent. The only thing that had to be changed was to crimp the electrical connections. A light went on in my head and I looked into my FSMs for the RX turbo and the XT6. Turns out the stock fuel pump for both cars are EXACTLY the same. Same capacity (60L or 15.9 US gal or 13.2 Imp gal), Same Location, Same Type (Electromagnetic pin roller), same discharge pressure, same Flow (95L or 20.9 gal), same EVERYTHING. The pump we both have on our XT6s is this: http://store.summitracing.com/default.asp?target=partdetail.asp&part=MSD%2D2225 It's an MSD inline (external) fuel pump rated for 43 GPH. If I'm right, it won't be a direct bolt in but with some slight modification it should be able to fit our EA82Ts as well. I'm almost confident about it. At least this is one part of the fuel system I won't have to worry about. "Made in the U.S.A., the pumps are ideal as "boosters" for nitrous oxide applications, or as stand-alone pumps for multi-port EFI systems on engines up to approximately 500 HP."

Nice write-up Garner! This is the part that bothers me. I like playing with timing and adjusting air/fuel ratios. Beyond that, I have very little time in all the other details. I'm really interested in reading more about anyone who has installed this and can talk about the before and after results...not theory.

That looks like an interesting setup. Cool! Wish I knew how to make something like that. Would save me the heartache of trying to find bigger fuel injectors.

You need to break into that warehouse and uninstall it. You need to do it NOW. Go Will! It is your destiny.

Up the stock fuel pressure regulator? I don't know! Can you up the stock fuel pressure with an aftermarket unit? Yes! http://www.ultimatesubaru.org/forum/showthread.php?t=31047&highlight=dyno

I know! When people talk about the flow of fuel injectors, they usually talk about the rate of flow at the standard 43psi. This way, no-one has to say, "my injectors flow (enter cc) at (enter psi). Most of the time you don't hear/read this. They only state the injector flow rate and the assumed psi is at 43psi (which is a standard). Ours flow at 245cc @ 43psi.

Kudos!

I'm really interested in this setup. I'm a fool! I need to know the details so I can setup something similar. I'm not looking for anything perfect. Your setup will allow me to do what I want to do. I'll go look at your pics. EXACTLY....what parts do I need for the 1 or 2 injector setup? I mean everything? Any instructions on exactly how to set our turbo car up just like yours? I know I'm asking a lot but I don't want to screw anything up and I'd like to get everything I would need to make this work like yours. Thanks! And oh yes, congrats on your 1/4 mile times. That is awesome to say the least.

Anyone have any engine pics of the Subaru R2? What is it? Here are the specs......... "The Subaru R2 has a new supercharged four-cylinder twin overhead-camshaft petrol engine with an Active Valve Control System which provides a wide power range which is fully exploited by the seven-speed sports gear shift." http://www.ultimatecarpage.com/frame.php?file=car.php&carnum=1784 You can always try to steal some supercharging ideas from Porsche. http://www.928motorsports.com/928sc.html I haven't heard of anyone trying to steal the idea off of the old 1 car 'concept' supercharged 2.5ltrd subaru that was made a while back. Subaru decided not to go through with it. I believe it was a Baja that was supercharged. They scrapped the whole thing and would not give any info to anyone about it. The company that did the design also wouldn't share any info with anyone. I know because I was one of the peeps that called them. I forgot the name of the company though. Ah (In my Yoda voice).........The Subaru ST-X it was called. Subaru Truck Xperimental. Re-edit....went looking for an engine pic.

You are correct sir. I had to look up fluid at 'dictionary.com'. Edumicate me! The pressure is determined by the size of the pulley on the supercharger. " Q: How do you change the boost? A: On any belt driven blower, such as the Powerdyne, you can change the amount of boost by changing the size of the pulley on the blower. The smaller the pulley the faster the blower runs and the more boost it makes. Currently Powerdyne offers two boost levels, a six pound unit and a 9 pound unit." Check out these supercharger FAQs for some information. http://www.powerdyne.com/tech.htm http://www.theoldone.com/sc/faq.html

Nope! You couldn't get closer to sea level then where I was at. They are 93ft above sea level. No need to compare unless you are as bad a driver as I am. Again, I just need to work on my driving skills. I know what I need to do.

I'm an idiot! Now that I got that out of the way, I'll ask this. I thought that pressure INCREASES when you go to a smaller pipe. I thought this applied to not only fluids (Like a fuel pressure regulator) but gases as well (like exhaust pipes). So in your case, I would've thought that if it was only a factor of going from the supercharger to a smaller pipe within the intercooler that boost pressure would increase. This is not taking into account the 'restrictions' inside of the intercooler itself. The 'restrictions' inside of the intercooler I'd say would cause you to loose boost pressure.

This is VERY interesting information. First off, that maf sensor you are speaking of plugs right into our stock Maf sensor harness. This is what you are stating right? Has anyone tried this already? I'd love to try it out before turning up the boost. It would be interesting to see what performance gain/loss could be had with stock boost settings and just a change in the Maf sensor housing. I never checked to see if the RX turbo and XT6 has the same type of maf sensor plug. If they do and the Nissan maf sensor plugs into the XT6s maf sensor wiring, I will thank you a million times over. I've been looking for something like this for a while. http://www.xt6.net/forum/viewtopic.php?t=1862&highlight=svx+maf+sensor Now onto the fuel injector. Our stock fuel injectors are rated at 245cc. There's no point into going to a fuel injector that flows at 259ccs. I'd think something larger would be in order. On another related note, congrats on your 1/4 mile times, especially at your altitude. With my current mods, I was only able to muster a lousy 19.2 @ 75mph the one and only time I ran my RX turbo at the dragstrip recently. I'm a lousy driver and my 60ft time was 2.8 so that says a lot. Plus, I shift slower than my grandmother. I don't care though. I was more interested in my trap speed and was somewhat disappointed. My Outback Sport wagon traps at that speed with less hp. I got work to do....
