Default GL-10 Wagon

Hey guys I just wanted to introduce myself!

I just got a 1988 GL-10 4WD Wagon along with two of my friends. One got a wagon like mine and the other a 4 door sedan. We were wondering what can be done to them besides exhaust, intake and other easy everyday stuff that helps this engine out? I know we aren't going to make big power gains but this is just to mess around in. Besides using mine as a commuter car to work I would like to autoX in it just for fun.

Default stuff

Intercooler, raise boost.
More air in, more air out (intake and exhaust.

Something like this


12PSI, RX7 TMIC, FT4WD with locking center diff, Accell superstock coil and wires(not pictured), Rear LSD, 14 inch pug steelies, cone filter

Theres more you can do, but I am usually broke.. and cheap...I only have about $700 in my wagon.. and that includes purchase price of my previous wagon, which is where the motor came from.

That has the EA82 in it, right?

check out:

http://www.xt6.org

It's dedicated to the XT6, but there is a good amount of information to get started with the EA82.

Hey Calebz i like your intercooler setup. I been thinkin of doing the same thing. I have a '88 rx sedan an i have an air filter setup identical to yours and a high flow exhaust...but no boost. How do you up your boost? I was new to a turbo when i bought my car about six months ago so i don't really know much about what i can do. i am now in the process of pulling the motor and a complete rebuild and when i go back together with it i would like to be intercooled and push a little more boost. Any suggestions would help. I like your car. Thanks

For a boost controller, I'm just using a cheap home made type thing.. They cost about $10 to make with parts from Home Depot .. Someone actually made this one for me. If you look at the pic, you can see it mounted just to the right of the passenger side strut tower. its the little brass thing

They can be had on ebay for $20 or less. and only take about 5 minutes to hook up.. and another few minutes to dial in. Boost gauge is required.

The intercooler is a stock 87 or so RX7 TII intercooler. Mounts were made by me. all of the piping is a combination of stock RX7 intercooler hose and stock mitsubishi starion/dodge conquest intercooler piping. the only modification done to it was I welded a small nipple onto one of the pieces of metal pipe to run the BOV/Recirc valve. A hood scoop is really kinda necessary to help the IC do its job.. I don't have one on there yet.. hope to fix that in the next couple of weeks.

All in all, it was really rather easy and cheap to get all this stuff in there.. most of it fell into my lap by luck.. the IC and BOV came from a friend that was stripping an RX7.. he had recently converted a dodge conquest to a ford 302, so I snagged the IC piping from that..the rest is history.


PS.. just noticed, the pic was taken before the BOV was installed, so don't go looking for it in the pic.. its not there I'll see about getting an updated pic up there tomorrow. If you want more detailed pics or explanations, let me know.

Can you pump up the boost on the 88?

I read that the computer for them retards the timing if you do is that right?

Also do you know where I can get a write up of how to make my own boost controler?

Yes you can pump up the boost on an 88. Its identical to my 87(actually, about 3/4 my car is is 88.. mostly just the body is an 87 now.) The IHI RHb5 is good for 14-15 psi.. I wouldn't go above 10 or so without an IC.
No, the computer doesn't retard the timing if you up the boost. 87 and up have a fuel cutoff if 9-10psi is sustained for prolonged periods of time.. Never been a problem for me though. you can install a saab APC system to help control timing advance/retard under boost.

There is a write up online for how to make your own MBC.. I think it was geared toward the RX7 crowd, but it doesn't really matter.. it will work on yours too.. I will see if I can remember where that write up is. Thats what mine is based off of.

Heres a link to one write up.. its basically the same idea as the one I am using.

http://home.att.net/~jason510/ManualController.htm

Edit: Found it.. This is the one I have in my car
http://www.geocities.com/chmwatson/FAQs/mbc.html

Note in step 7 it instructs you to drill a very small hole.. don't bother.. you won't be boosting high enough to make it worth it.

what exactly is a saab APC system?

Are you just running a stock distributor downstream of that Accell coil? And what kind of advance are you running? Is it pretty easy to hear knocking in the EA82 motors? Is the factory ECU good at retarding timing when there is knocking detected?

I was looking at my GL10 engine donor tonight, dreaming, and noticed that it doesn't have a siamesed intake port in the head like the carbed engine does. Is the exhaust port still siamesed? And what else on the EA82T is really different from a carbed EA82?

And definitely post some pics when you get that hood scoop on.. What are you getting it off of? I was thinking of going with the 02-up WRX scoop, but am not sure if it is too wide to fit on the ridge of my hood. It is a fairly attractive scoop though.

Sorry for all of the questions.. I got parts in last night and got to work on the car, so it has got me thinking again..

Thanks..

Its a boost/knock/timing control system. One of the best stock units out there IMO. Instead of just retarding the timing when theres knock, it will actually lower the boost until the knock goes away.

Yes

Stock 20degrees BTDC

Dunno.. never had any knocking in my turbo motors that I am aware of. I had an SPFI loyale that pinged like mad.. it was very obvious
Quote:

Seems to do ok.. haven't had any knock/ping or detonation problems to deal with.. not really sure how good the knock system is.

Not really sure what you mean

Heads are completely different. Carbed has a higher CR than the Turbo motor(SPFI is even higher) And of course the intake and exhaust manifold is different

Its a secret I'll post pics when its done.. and yes, you are right in thinking that the WRX hoodscoop is too wide for the hump on your hood.. its too wide by about 5 inches if I remember right.

If we keep this up, someone might start to think I actually know what the hell I am talking about. Can't have that

Oh man this will never die you are going to get a lot of questions from me if I don't blow my engine anytime soon. Thanks for the MBC site I might make one sometime this week if I'm not to tried from work. My friend and I wanted to go look for intercoolers from the junkyard. I was wondering if you know a good one to use and if they will fit up front or you have to have a TMIC? I was thinking about a Isuzu box truck IC or maybe one out of a Volvo or Saab.

Saab 900 intercoolers are great. They are small enough to fit almost anywhere, and they cool the air fairly well. The saab 9000 and volvo ICs are wayyyyy too big for a little subaru..( I have owned a bunch of saabs.. last one was an 9000T.. I checked.. it won't fit in a soob without some serious shoehorning) . I didn't try for front mount beacuse everything is right on top, and theres all that space where the spare tire goes. If I removed my AC condensor, I could probably get a front mount in there, but the plumbing would be a pain. Besides, I live in Texas, I want my AC. I know of a guy in Australia that has done a Front mount in an EA82 Turbo Sedan, but he had to make humps in the hood to clear the plumbing, as it ran up over the core support. .. Its all a matter of how much fabrication you want to do.

Honestly, aside from the RX7 IC, the best fitting IC I have seen has been the WRX

I guess I could also look at some SMIC from a talon/eclipse/laser. I took the exhaust from the second cat back but couldn't really tell if it was much fast. I sure it was cause I hit 80mph a lot faster than I hit near 70 before.

Whichever IC you end up getting, mounting it up top is still the easiest , and in my opinion best option. theres lots of room there and with a hood scoop, you will get plenty of airflow.
Mitsu starion/dodge conquest ICs are fairly commonly used on soobs. WRX IC seems to be the IC of choice. Thunderbird Turbocoupe ICs also seem to fit well. Saab 900 ICs work, and even though they are a side mount IC, they get mounted on top on a soob.

I looked at using an Eclipse IC as well. Seemed like with a little work, it would fit.

In the end, I chose the RX7 IC because it was laughably simple to plumb adn mount. They can be had on Ebay for under $40 all the time. Have seen a lot of them go in the $15-$20 range

I'll have to see what I can find. Might end up getting more than one. Also thinking about looking for a blow off value of a 1g eclipse but I don't know if it you would on this but I have heard of people using them on other cars.

I am using the stock blow off valve from the same RX7 that the intercooler came from. Not really necessary if you are running stock boost, although it will help with turbo lag between shifts a little. The biggest thing to remember is that because these cars use a MAF system instead of a MAP (like newer soobs) They don't really like to be vented to the atmosphere.. it kinda screws up the computer's A/F readings. Mine is vented back into the intake boot after the MAF.. its plumbed into that big plastic tube that is on the back of the intake boot.. I'll get pics if you want.

Oh ya... one thing... shorten the shifter (hacksaws work wonders) and put in some XT seats or something with a little more lateral support... wont make the car faster or make it handle better, but you will have more fun cause you will stay planted in your seat and you can shift faster

I wish it was a stick and the seats are pretty good for support. It might be cause there gl-10 seats or they were just all like that.

GL-10 seats are kinda special because they have a height adjustment.. XT seats have better bolster supports.. but they won't match your interior.

Too bad your car is an auto.. That can be fixed though.. mine used to be an Auto too
