Unhappy I need some advice.....

Well, I just became the proud owner of an '88 GL-10 AWD Wagon recently. I have had to make a few repairs to it as it was "well used". Anyway, The car was running just fine before I replaced the clutch, but since then has had a reoccuring problem of not wanting to run. It will crank with no problem, but once I finally get it running after finagling with the distributor, it seems as though it is having problems idling, which gets better or worse with distibutor adjustment. I cannot see or find any loose connections, so this is beginning to drive me 's!!! Please HELP!!!! Any help is welcomed as I am almost to the end of my rope with this problem.

Thank You to everyone in advance!!!

Sincerely,
Patrick

Man, there are so many possibilities...

Vacuum leaks come to mind. You say it will satart by messing with the distributor.. have you had the distributor out for some reason? is it possibly a tooth off?


I suppose making the 150 mile trip to my house is out of the question eh? I have a pile of spare stuff.. distys, coils, MAFs...

Well, trust me, If I didn't have to ever shut the car off, I would be on the road today.

I have checked sooo many times to see if the disty is off by a tooth or two. Every time, it is the same thing. I was thinking that maybe there is something wrong with the pickup coil. Who knows....... I will go out and check the vacuum routing again(the engine isn't the original. It came from Japan out of a wrecked GL-10, or so I was told by the previous owner.).

Hey, I got some good news! I was messin' around with the disty yesterday(Praying the whole time I was working on it), and I think everything is actually aligned now. The car is running pretty good and I have not had any problems with ignition timing studder(when the engine is under load) or anything. I drove it around today and everything seems ok. All I can say is THANK GOD!!!!

As soon as I get it registered and inspected, I'll talk to my wifey about making a trip down there. Oh BTW, I'm not sure that my GL10 could actually be considered stock. LOL

Here is a small list:

Top-mount (converted Starion) intercooler
Intercooler piping(2" on hot side/ 2-1/4" on cold side w/ thermal wrap)
Adjustable boost controller
3" intake(after MAF) w/stainless steel cone filter
Tcc Work BOV(30psi rated spring) rated 119db@4 ft away

Soon to come:
2-1/2" bellmouth downpipe or divorced wastegate w/downstream merge
High-flow cat (2-1/2" in/out)
2-1/2" cat-back exhaust w/resonators(2)
High-flow canister muffler
Coil-overs
KYB rear shocks and front struts
Polyurethane swaybar bushings

That's not all, but it's all that I can think of off the top of my head.

Interesting.. Perhaps you would be interested in reading this then ... http://www.ultimatesubaru.net/forum/...hlight=preview

Thats the most recent round.. Already done are the TMIC, boost controller, turbo timer and other such things..

Got one of these on yet?

Yeah. I got a WRX hood scoop. Your scoop looks better though. Judging by the stuff you got, your car is going to be a monster!!! I'm just trying to get about 200whp. If I can gain more, that would be awesome. But I'm dealing with the stock IHI RHB5 vf11.

But I'll tell you one thing, I made a (3" aluminum piping) fenderwell intake today. It sure helps out. Now I just have to get some more thermal wrap for it so I can keep the pipes from getting heat soaked. And I changed out my boost controller for a 3/16 restrictor. That seemed to help out too. I still need to get the pipes on my intercooler upgraded too. I might have the guys at Wasabi Racing do that for me.

Wasabi is now closed. Their dyno was apparently repo'd.

FIS is cooler anyway. After dealing with both(or attempting to), I wouldn't have gone back to Wasabi anyway. But thats another story. Besides.. FIS is only 10 minutes away from me.

you've got a VF11? Thats about equivalent to the TD04 13g I'm using.

or did you mean the stock EA82 turbo (VF7)?

I meant to say VJ11, not VF11. I think I was thinking about a VF22 and then started talking about a VJ11 and got the two mixed up. I used to have a turbo off of a Ford Probe GT(which was a VJ11), and I compared the two and they looked almost identical except for cosmetic differences(turbo inlet and exhaust mounting flange). I'm sorry about the mixup. So it's a VJ7? Does that mean that it is not as efficient as the VJ11? I wonder too if the my EA82T and the original are the same specs? The motor that is in the car now came out of a Japanese Subaru(shipped from Japan). That swap was done by the previous owner after the heads on the original cracked. He got a better deal for this motor, than he would've had to pay out to get new heads. And the engine had less than 40K on the old ticker.

I didn't know that Wasabi Racing had closed. I guess I'll have to try and find that FIS place and see what they can do for me.

Let me ask you a question. Do you think that if I were to put a cooler inline to the coolant pipe that goes into the turbo, that it would do any good? Hypothetically, I was thinking that if I can cool the coolant a little more before it goes into the bearing housing, that it will help keep it cool and make it last a bit longer. What do you think?

.

Interesting idea..I know the newer soobs have an extra little coolant tank for a similar purpose.

I think that I will give it a shot. I figure, the cooler the bearing housing stays, the longer the turbo will last and the less thermal stress will be put on the oil passing through the bearing section.

UPDATE:

Yesterday, I went out and purchased some NGK Iridium plugs for the Sube and installed them. The idling issue seems to have been addressed now. The idle also seems to have smoothed out quite a bit. I finally figured out what was making my CEL stay on and sometimes flicker. The stupid plug on the Coolant Temp Sensor was broken. I fixed it temporarily so that I can get the car inspected. Hopefully if everything goes well, I will also be purchasing a Holley Annihilator HP ignition setup. It is supposed to give you multi-spark from idle to 3K rpms. Then, it increases the spark output after 3K to give you a higher voltage spark. All I can say is, WORKS FOR ME!!! lol

Oh yeah, and I also installed a power steering cooler too. Now the power steering feels real tight. I like it!! It's almost done and road ready. The closer I get to being finished(if that ever happens ), the more excited I get about the car.

Hey I actually got a good look at my turbocharger a couple of minutes ago. It is a VF series turbocharger. It says so on the info plate that is cast into the compressor housing. It says: Turbo Spec. VF [48612]

Yes, IHI RHB5 VF7 is the stock turbo for an EA82.. Ugly little bastards

I have a couple sitting in my garage.. I hope I never have to use one again, My motor looks better with a TD04 on it.. hopefully it works as well as it looks.

I like my little VF7. It gets the job done(even though I think that a VF22 or something like that would get it done better!!). Hey if you ever want to sell those VF7's, you know who to inform. I have been thinking about buying another one and have a turbo rebuild shop see if they can't build me a hybrid of some sort. Or maybe just put a different compressor wheel in it. I love the fast spool characteristics of my little turbo, but I want more of the "kick in the pants" feel of a larger turbocharger. I don't know. Maybe I'm thinking too much.

Hey I got a question for you. When you hammer the throttle, does your car try to pull to the left? Mine does it really bad in 1st and 2nd. I was just wondering.

Mine used to pull under acceleration.. back when it was Part time 4WD.. Now that I have a full time tranny, no more torque steer

On the flip side, I have to be a little more careful accelerating around corners.. With the FT4WD trans and the LSD, it tends to push in the back a little bit.

Well, the weird thing, is that mine has fulltime 4WD(w/LSD front and rear, also has diff lock feature) and it still does it. But under normal throttle range, it drives just fine. I guess maybe I need to get an alignment.

It doesn't? I was just assuming and this is what I got in return. Valuable Info!!! At least I know now, Thank You. Well I'm still kinda new to this car so I'm still learning about it. Sorry for the "Noob Error."

Guess that explains why it pulls to the driver's side when under hard accelleration. Now this is starting to make a little sense.

UPDATE: More Good News!!!

I redid some of the vacuum routing last night and the car seems to be on the up-n-up now. There was a vacuum solenoid(the one directly to the right of and also above the coolant temperature sensor) that apparently wasn't doing jack squat. Besides the fact that one of the vacuum fittings broke off after I found out that there wasn't any vacuum flowing through it. I'm guessing that it had something to do with the idle, because after some finagling, the car idled smoothly and doesn't keep dying after I crank it. I went out and started the car today and it started on the second try with absolutely no problems whatsoever. Anyway, I took the car around the block and it pulled really freakin' hard and spinning the tires all the while(road was a little wet). As soon as it got good traction it took off like a rock out of a slingshot! I thought I was going to break my neck!!! WOOOHOOO!!! It was such a great feeling. I don't think that this smile will come off of my face for quite a while. But if it feels this good with no exhaust(open downpipe), I can't wait to see how it does when I get my 2.5" exhaust put on. I hope that it pulls even harder. I guess we'll see. I still think I'm going to put a cooler inline to the coolant pipe that goes to the turbo.

I was wondering too, I'm going to be changing the fuel filter soon. Is there anything weird that the car is going to do after I change it? I mean besides the obvious increase in fuel flow and possible gain in power as a result. I'm talking about like not starting or something to that effect.

I don't suggest you put an extra heat exchanger in line with the turbo water supply. Unlikely you will do any harm but you won't do much good either. The main function of the water supply is to keep the oil from coking in the turbo.(after shutdown) It takes oil to hit >350 F to coke. Water line will keep it well well below that. The main fuction of the water line is actualy after shutdown. The water left in the water jacket will counteract heat soak after shut down. Which is where most coking occours. Water left in the water jacket will flash into steam before the oil can reach coking temps. If anything by adding extra tubing, fittings, etc you may reduce total flow to the turbo with little to no benefit. You may also keep the turbo from reaching designed operational temps (for maximum efficiency) Nevermind effort and money wasted in doing it.

Oil coking was a common problem with turbos and the reason turbo timers were created to combat. With the advent of turbo's with water jackets coking is no longer an issue.

Fuel filter, you should not have any issues replacing it. The car might crank a little longer when first starting. After that it should be all normal.

KOOL!!! I don't want to restrict the coolant flow to the center section of the turbo. Don't need any more problems with this thing than I've already had. And I already have installed a turbo timer so I guess I'll just stick with that. I just figured that the cooler I could keep the bearing section, the longer the turbo would last.

Thanks for the info on the fuel filter. I had read a few threads where people were talking about after replacing the fuel filter, that their cars wouldn't start. So I didn't want to have any drama when I replace it. Thank You again.
