Go for it! Send/post up some pics of your project as you go through it and the finished results. I'd look forward to reading about it. Good luck!

Awe man! I love this. I'm looking for this feeling once again in the older Subarus. It wouldn't be the same in a WRX or STi. I'm right there with you.

Pics! Pics! What type of panty hose do you recommend? Sheer Energy or another type that runs? Whatcha doin' with panty hose Will? :-p I'll stop now!

Congrats on getting your car up and running. Must be a great feeling. Someday, I'll be hardcore like you guys and work outside in the snow, at subzero temps, with hail coming down. I'm working on it! :-p

Some could argue that I'm only running stock boost. The significance margin will get wider once the boost gets turned up. I can't imagine what the difference would be of a non-intercooled EA81T or EA82T at 13psi vs an intercooled one. The difference would start to get more dramatic. No matter! It's better safe than sorry. Check this really good post out by 'All Talk'. http://www.ultimatesubaru.org/forum/showthread.php?t=15554&highlight=temp It's information about before and after intercooler installation. I was fascinated by the results and always thought of getting an intercooler (even though I didn't own an EA81T or EA82T yet). I still refer to this thread as a reminder.

No, none of that at all. I understand that when the throttle plate closes and the air is vented to the atmosphere, the car SHOULD bog or something from the extra fuel being injected to the cylinders without the metered air with it (that's vented to the atmosphere). Somehow, it runs just fine. I haven't tried to figure it out and just accepted it. No stutter, no bog, just smooth running. I likey!

Would be nice if someone posted an installation instruction of sorts. Most of us are idiots when it comes to these things.

Interesting post! I had purchased some Nissan SR20DET Injectors for various reasons and also purchased a set of 1.8ltr Subaru turbo injectors (XT, RX, etc). I don't know which of the turbo Subarus these 1.8ltr injectors were from but I got them to turbocharge one of my XT6s over a year ago. The Nissan injectors were for upgrading my Impreza Outback Sport's injectors for turbo application. Here's a pic I posted at Nasioc on a similar discussion. The 1st and 3rd injector is from a 1.8ltr turbo Subaru while the 2nd and 4th injectors are from the Nissan SR20DET. I'm not sure how this correlates to the Nissan Maximas and such but if they are similar, you can be the judge as to whether they will fit or not. It's said they will work earlier in this thread. Have the Nissan injectors been installed and running successfully in either an EA81T or EA82T'd engine?

You can always make a video of this you know. *hint, hint*

Brian, You don't have to plumb in the BOV do you? I have mine venting to the atmosphere and there haven't been any problems so far.

So you have a stock WRX turbo and downpipe. I thought you had a TWE downpipe. What's going on? :-\

I forgot to thank you for this info Will. Thanks!

I dunno what to tell you. I'm not a good driver of manual trannied cars so blame me. Everyone's results can be different still, even with the same make/model/year car and the same driver on both cars. If I'm going to be a poor launcher and shifter of this thing, perhaps I can consistently do it so I can see the affect of a mod or two.

I 2nd Gary! I know if he could use them, I probably could too.

Shadow, give me an hour or two tonight. I'm working on that right after this post. I'll be posting before and after intercooler installation 0-60 and 1/4 mile results. Pay mind mostly to the 1/4 mile trap speed. I don't know how to launch a manual RX just yet. I'm learning! I can do consistent slow launches though. Be back with some numbers later tonight.

I wasn't sure so I checked. Here are some of the things I read from the link I provided above. " Eighty percent of the benefit of adding Unorthodox Racing's under-drive pulley for the Altima is from the weight savings. The other twenty percent is gained from under-driving the rest of the accessories like the power-steering, water pump, alternator and A/C." From here: http://www.nissanperformancemag.com/november02/altima_ur/ "Approximately 85% of the gains produced from the UR lightened pulleys can be attributed to weight reduction. The stock GA16DE pulley weighed in at 4 lbs 12.6 oz, The Unorthodox pulley weighs 1 lb 7.8 oz." From here: http://www.nissanperformancemag.com/january02/ur.shtml It seems that most of the 'gains' that are were made were due to the weight of the pulley. The remaining gains (15 - 20%) were do to underdriving the pulley. I dunno about these things but that's what the folks at those links say. :cool:

Interesting you pointed this out. I didn't know about this law. The only reason I got to getting pulleys for my cars is because of some old magazine articles of Sport Compact car I used to love reading. They used to show before and after results of modifications on a dyno of the project cars. They don't do it as much anymore so I cancelled my subscription. I just to love those magazine articles and it was 90% of the reason why I purchased the magazine. The pulleys were always consistently showing some horsepower/torque gain on the dyno. We know it's not more power made but more power available for the car to use. Here, I'll show you some examples. " Adding the crank pulley can be a little deceiving compared to other mods because there isn't a definite surge anywhere in the powerband, so the seat of the pants dyno is no good here. To verify the increases we headed up to R & D dyno to measure the results. There's a progressive gain in power of 2-3 hp from 2-4K RPM, after this the increase in hp is approximately 4-5 until 5K RPM where we gained 6.5 hp over stock and 3 lb ft of torque." Project Altima 3.5 From here: http://www.nissanperformancemag.com/november02/altima_ur/ "At peak, we gained 1 to 2 horsepower. However, in the usable area of the powerband, 4000-5500 rpm, the power gain was 4 to 5 horsepower. A very respectable gain for a relatively inexpensive part, with no adverse effects." Project 200SX From here: http://www.nissanperformancemag.com/january02/ur.shtml 1996 Neon ACR "Maximum Gains: 8.2 HP 5.6 FT-LBS" From here: http://www.modernperformance.com/dcx/neundyno.shtml These are just some examples of why I considered doing a pulley install and test. Just didn't work out the same for me. Hehe!

More GTech runs done tonight. Car: 1989 2.7ltr Subaru XT6 (AWD/Autotranny) Mods: Intake, Pulley, 2.25" cat back Exhaust I did a total of 4 runs. 2 in one direction and two in the other direction. South Direction 0-60: 7.87 1/4 mile: 16.15 @ 90.3mph 0-60: 7.94 1/4 mile: 16.21 @ 88.3mph North Direction 0-60: ? (I'm an idiot) 1/4 mile: 16.14 @ 88.5mph 0-60: 7.87 1/4 mile: 16.14 @ 88.9mph Average: 0-60mph: 7.89 1/4 Mile: 16.16 @ 89mph

Nope! No fan on the intercooler. There was a large fan in the front of the car but none on the intercooler itself. It's cool! There are other tests to see the benefit of the intercooler. G-Tech Pro and 1/4 mile times. I'm done testing it on the dyno though. Time to get those Techworks parts installed and get to cranken up the boost. It'll be a while before you guys get some numbers from me though. I looked at the bottom of my radiators and didn't like the look of what oxidation and rust was doing to them. Just touching the radiator turned it to a fine powder. After taking care of the cooling system (new radiator, cooler thermostat, etc) and installing some gauges (fuel pressure and EGT), the the fun with boost begins. I'm sure others here will have some concrete numbers of what some of the Techworks parts does though. Thanks for the support guys!

This comparison is of the RX turbo with and without an intercooler. Mods at this point are the Garner Pulley and K&N air filter. The blue line is with an intercooler and the red line is without an intercooler installed. For details about the intercooler being used, see link provided in the first post. The first dyno chart is a horsepower comparison while the 2nd is a torque comparison. Boost is stock. Let's look at the graphs: The hp graph shows that with the intercooler installed, there was a LOSS of max hp. Max hp without the intercooler installed was 77.22hp while max hp with the intercooler installed was 76.13hp. Max torque without the intercooler is 96.48lb-ft while max torque with the intercooler is 104.41lb-ft. Take a look at that point between 2300rpm and 3300rpm. See that nice fat spike in hp/torque there? That's not a fluke. All 4 of the dyno runs I did with the intercooler installed had this jump in torque right here. None of the other 8 dyno runs I did had it. I picked a random point in this jump (2700rpm) to demonstrate just how substantial that spike is. At 2700rpm, non-intercooled the RX turbo made 43.82hp and 83.75lb-ft of torque. Now intercooled, the RX made 54.41hp and 103.98lb-ft of torque. That's a 10hp and 20lb-ft of difference in torque. You can feel this torque while driving, not as a push your head back in the seat type of feel but the car feels lighter. I could add more but I have to go to pick my wife up. I can say the ride home was quite different than the ride up to the dyno shop. The car felt lighter AND faster throughout the whole rpm range despite what the dyno shows. Shifts are smoother and I do not know to this day how the intercooler does this. Between shifts isn't jerky like it is without and intercooler. I noticed this after the first install but attributed to a fluke or my imagination. It's real. So there you have it. This does not mean that your pulley, air filter and/or intercooler will yield the same or similar results. It does help us keep some things in perspective and not get carried away thinking we will gain 'X' amount of hp/torque doing certain mods. There are many other intercooler combos and such that could use testing. Choose your mods wisely. L8Rs.... *BTW: If I've made any spelling or grammar errors, please let me know. Also, if any misinformation is posted, please PM me so I can correct it. I'm tired at the moment and typed through this pretty quickly.

Dyno runs part #2. Autozone Filter vs K&N air filter Again, these runs are with a Garner pulley and Autozone air filter vs Garner pulley with K&N air filter. Both filters have been cleaned on the same day 2 days ago. Air filter was changed on the dyno. Link of pics of the air filters is in the first post. Here are the results: What you are looking at may be confusing. The first chart is a horsepower comparison of the Garner pulley/Autozone air filter combo vs the Garner pulley/K&N air filter combo. The second chart is a torque comparison of the Garner pulley/Autozone air filter combo vs the Garner pulley/K&N air filter combo. Notice the K&N air filter is making a little more horsepower and torque than the Autozone air filter. The Autozone unit makes a max of 75.82hp vs the K&N's 77.22hp. As far as torque, the Autozone unit made a max of 92.19lb-ft vs the K&N's max of 96.48lb-ft. I picked a random point on the graph so you could see the difference in hp and torque. Notice at these points the K&N makes 4hp more and 6lb-ft more of torque at 3800rpm. Just something to look at in case you are thinking about getting a random air filter from Napa, Pep Boys, Walmart, etc. You may be better off getting a Greddy, K&N or other name brand filter. *Garner, trust me buddy, it's not your pulley that's the problem. I KNOW it's freeing up hp/torque. Something else changed with my car from the last run to this run but I have to post real world results. The best way to do this is for me to change the crank pulley on the dyno but that's $$$ due to time restraints. I'm sorry. I'm definitely keeping it on though. The weights on the scale doesn't lie and it's lighter by 2lbs. Thanks gain*

Hey all, Just got back from the dyno shop. The car dyno'd today is a 1988 1.8ltr Subaru RX Turbo (FT4WD,Manual). I did a baseline run previously and you can see the results here: http://www.ultimatesubaru.org/forum/showthread.php?t=24534&highlight=rx+turbo+dyno Today I went about testing three things. First thing I tested was the 'Garner Pulley' I had installed. The Garner pulley was made by a member here who goes by the name *drumroll* Garner. So, I named it so. Since my previous dyno session the only thing done to the car was the addition of this pulley. If you want look/weight info/size/etc, you can find the pulley info here: http://www.ultimatesubaru.org/forum/showthread.php?t=26139&page=1&highlight=garner+pulley The second thing I wanted to test was the air filter. I had one Autozone air filter that I thought may have been restrictive due to what had happened when I cleaned it. A K&N air filter of a different design was put in it's place to see if a difference in hp/torque would be observed. More info can be found here: http://www.ultimatesubaru.org/forum/showthread.php?t=27803&highlight=air+filter The last thing I tested was the affect on putting on an intercooler. Now remember, all intercoolers are not created equal. I used an air-to-air intercooler that's used on the Ludespeed Stage II turbo kits for the Imprezas. This does not make the intercooler special by any means. This is where I got the intercooler from (I had a Ludespeed kit installed on another car then I uninstalled it). More info on the intercooler's look/placement/etc can be found here: http://www.ultimatesubaru.org/forum/showthread.php?t=26592&page=1&highlight=Intercooler+dummies Ok, now for the dyno. I've learned from dyno'ing my cars to NEVER expect anything. You don't know how your car has changed from the last dyno and you don't know what changes in modifications will yield what result. DO NOT go into a dyno session expecting 'X' amount of hp/torque. You may end up being disappointed and even blaming the dyno operator's machine saying something is wrong with it. They don't like that. I know because I've heard of the stories. I did a total of 12 pulls. Cool down, 2 pulls, cool down, 2 pulls, make change (Ex: air filter), cycle starts again. Out of the 4 pulls, I always pick the 2nd highest of the consistent runs. If all 4 are consistent, I pick the 3rd highest. Just a habit of mine. No pulls were done unless the throttle body/intake manifold was 89F or less. This was measured by a laser beam temp sensor the shop (Xotic Motorsports) own. Enough talking...lets see some numbers. *Thread not done---Rebooting computer to complete* Sorry! Cont'd........ Here are the charts to compare the horsepower and torque of the stock run vs the Garner Pulley run. The max hp of my stock run is 79.24hp while the Garner pulley max was 75.82hp. Stock torque max is 95.19lb-ft while the Garner pulley's torque is 92.19lb-ft. Why the loss in hp and torque? So you may ask, what the heck is going on? Why is the Garner pulley run making less hp/torque than your baseline run when the Garner pulley is lighter? I haven't made any other changes to the car. I had to replace a tire that was flat but it has the same tire on it when I originally tested and all those tires were new. I did clean the air filter recently but that wouldn't make for less hp/torque. The only answer I can say lies with the air/fuel ratio. Notice how much leaner I am running now vs when I originally ran. I do not know why I am running lean. I have no means to controll the air/fuel ratio at this time. I have no detonation/pinging as far as I know. Perhaps it has something to do with the 93 octane I'm using. Turbo'd Subarus are typically happy around 12.0:1 air/fuel ratio. No excuses! This is what it is and this is what I got. So now I'm starting off at a lower point. Next post will compare the Garner pulley (with Autzone filter that is already on it) vs Garner Pulley with a K&N air filter.

My wife named both of my XT6s. FWD XT6 = POS #1 AWD XT6 = POS #2 Yes, this is what she calls them.

Thanks SubaruTex. The RX is for tomorrow if my darn tire comes in today like it's supposed too. :-\
