What the heck are you talking about? It can't be over like that. Any pics! Sorry to read about this Will.

Need more info about this Outback. Can you point out to me/us where to find it?

Question! How much extra boost can you theoretically get away with using c16 gas if your max boost is reached at ....say 15psi with 93 octane before detonation?

Darn it! Someone take Will up on the challenge. DoitSideways, that's an interesting car. Color them draws attention.

Nah! Just 100hp N/A and about 140hp with the nitrous.

What do you mean by 'pretty well'? Do you mean it was a direct bolt on affair or did you have to tweak/modify it to meake it fit? If you had to modify it/them, what did you have to do to make them fit? Thanks! WJM, Did they fit?

BTW: Here was the last test nitrous runs I was doing with the XT6 at a 50hp shot. I want to go up to 75+ but the wiggly lines concern me. Retarding the ignition made things worse (more wiggly)....sooo. Perhaps I should go with a higher jetting to go for the challenge. Hey, you didn't say I have to stay N/A or go boosted right?

"Re: A challenge has been issued...Dyno results" Nice numbers Will! I am taking on your challenge. I have 3 things left to do. 1: Get an upgraded fuel pump, 2: Get upgraded clutch (Like you pointed out to me in a post/thread), 3: Remove the wet nitrous kit from the XT6 to the RX Turbo.... Here's my plan of attack. Boost will remain stock when running nitrous. When nitrous isn't run, boost will be bumped up but I'll use the fuel flow from the nitrous kit for extra fuel (with no nitrous being injected). If it's too lean, I change the fuel jetting. Too rich, change the fuel jetting and adjust fuel pressure. Welp, there you have it. I've just been moving too slow to get this done lately. The challenge is on. Need some excitement around here. I've been goofing off playing with the XT6 anyways.

Tomorrow? Damn it, you should know by NOW. I hate suspense!

Wow! I thought most people thought XT6s were the black sheep of the Subaru family. :-\

Pics!

Wow! Dennis, haven't heard/read from you in what seem like ages. Glad to see you are still around. Whatever happened to that RX turbo that I foolishly didn't purchase from you?

Maybe the power drop off thingamajigga after 5500rpm rears it's ugly head again with higher boost. I don't know why it does it stock but whatever causes it to do it stock may be doing it again at higher boost levels. :-\

I had to REALLY think about this for a bit. Are we all really sure that RX Turbo fuel injectors are 185cc? I found my old post at XT6.net where I posted the results of having my XT6 fuel injectors cleaned at RC Engineering. At 43psi of fuel pressure, it came out to 185cc. Since the XT6 is basically a 6 cylinder EA82, would you think that this is what was put into an N/A EA82 engine? If so, would this really make our RX turbo fuel injectors 245cc units? (I have my own thoughts on this but I just wanted to see what people think about all of this). Here is the result of my XT6 fuel injectors that got cleaned at RC Engineering at the same fuel pressure as my RX Turbo fuel injectors. Note also that the XT6s fuel injector make and type is different than that of the RX turbo fuel injectors. Another question would be what is the make and type of fuel injector of an N/A EA82 engine? Is it Nippon Denso saturated (XT6) or JECS Peak & Hold (RX Turbo) fuel injectors? Just trying to make for some good discussion.

Yes I did! Was going to do it myself but felt impending doom. Rather let someone else deal with it. Two parts broke off due to rust and being old, where the screws held in two injectors...or something like that. The dealership fixed it at their expense. I like that!

The dyno operator says that the reading you see on the dyno is offset by 1 if you have a cat converter. So my 12:0.1 is actually an 11:0.1 with nitrous. If I did not have a cat converter, then the 12:0.1 would actually be a 12:0.1. Will, if things go right, that old school 'record' is coming down......on the juice. I'll adjust the timing and everything Saturday when I'm not working. Muhahahaha!

Yep! Everytime I went for the RX turbo, it was $50. Actually it's $53 ($3.00 tax).

It goes by time. It costs $50.00 an hour for as many runs as your car can handle. The place is Xotic Motorsports in Cochranville, PA. http://www.xoticmotorsports.com/

All these questions. I forgot that I need a new radiator. The bottom side of my radiator turns to powder if you press down on it with your finger. Maybe it's powder-coated. J/K

Car: 1989 2.7ltr FWD Subaru XT6 Mods: Intake, pulley, exhaust, etc..... along with NX Express nitrous kit. I did 4 pulls two days ago. 2 without nitrous and two with nitrous. I was foolish in my testing and just didn't give a crap. Timing is advanced pretty far due to Delta Cams and I never retarded them (making me the retard). I just didn't care so please excuse the jagged lines in the nitrous results. Also, my bottle heater decided to go on vacation just before my dyno runs so my bottle pressure remained lower than it should've been. It came back from vacation on the drive home. I expected weird engine/mod gremlins from this car at some point. It never let's me down. Test runs where done from the bottom of 1st gear all the way up until it shifted out of 3rd gear. Nitrous was turned on in 2nd gear. I was most interested in what happened in 3rd gear. Here's the hp comparison before and after the nitrous was thrown of all 4 runs. Hp went up from 102hp to 141hp at the wheels. Here's a torque graph of all 4 runs in 3rd gear. Torque went up from 108-109lbs-ft to 145-149lb-ft. Not bad with only a 50 shot. It'll be interesting to see what happens with a bottle heater. Here's a clearer picture of what happened during my runs. These graphs are of the XT6 in each gear. All the hp and torque info is clearer and no missing lines. Note the jagged nitrous lines. I believe (pretty much know) it's timing related. I'll be more professional and less pessimistic next time. I know what I need to do. I'll retard timing about 2.5 degrees or so, be sure my bottle heater is working and at the right psi and change my spark plugs to 1 degree colder (I have some sitting right next to me....duh). I'm shooting (literally) for a 75hp shot or so. I'll post up the results when I get to it.

$106 dollars for me, not counting shipping. Speaking of RC Engineering, what did your injectors flow at on an average before and after cleaning?

Here's the data sheet. Enjoy! BTW: Here's something I thought that was interesting. I had the fuel injectors numbers from 1-4. They were numbered according the the cylinder they were spraying into. Cylinders #1 and #3 (which are closest to the turbo, especially #3) faired worse than fuel injectors #2 and #4. Even after cleaning they both were worse than the driver's side fuel injectors. They two good and two 'bad' fuel injectors were pretty much consistant with each other whether they were bad or good. What do you think about this?

Well dang! I never even thought about this. I'm not sure if it was even mentioned in some of the past posts. In this case, we DO have 185cc fuel injectors because the test pressure on my data sheet is 43psi. Now I look like a fool. I'm a disgrace to the board and I'll never return again. Just kidding! I'll go about posting up the sheet in a bit. I need to scan it. On another note: There is a standard pressure that injectors are tested at despite what they may flow at a higher or lower fuel pressure. What is this standard?

Hello all, I just got my fuel injectors back for my RX Turbo. For those that don't know, I own a 1988 1.8ltr Subaru RX Turbo (See sig). I sent my fuel injectors to RC Engineering Tuesday via Fedex overnight to have them cleaned. I had them overnighted back to me (I hate waiting) and just picked them up. I need to keep this brief but I'll be back with pics later after picking my wife and kid up. The truth is, the RX injectors do not flow 180cc, 185cc or 190cc like what was previously believed or told. The RX turbo injectors flow an average of 245cc/min. I have two that flowed 246.0cc, one 243.0cc and one 244.0cc after cleaning. I'll post up my before and after cleaning flow sheet as well as before and after cleaning pics. Right now, I need to drive up to the dealership to drop them off to be installed. BTW: The RC Sheet shows....... Injector Type: P&H 2.5 Injector make: JECS RC# PJ2H-245 Part# A46-000970 8217B If this is misinformation, I apologize. These injectors could very well be aftermarket fuel injectors if the stock RX turbo does come from the factory with 185cc fuel injectors. I do not know. This is what I got though. RC Engineering do not carry any injector upgrade for JECS made injectors for Subaru. I just called them before typing my last sentence. So there you have it. Proof will be shown in the pics I post up later. Comments, suggestions, flames are welcome. I'm just excited that I finally know what the truth is. I hate not knowing. Laters!
