So a few months ago a good friend of mine and Punkskalar's passed away. He was a fellow fabricator and an inspiration to me as a student. I had been working with him on some of his furniture design when he passed and as a result his wife and his business partner asked me to come and help clean out his shop. They gave me many of his tools which I now cherish and am very thankful for as well as this:
Its a 79 Subaru Brat. its been customized to say the least. It has an 86 Legacy motor in it with a turbo. The front fenders are all fiberglass that our friend made himself and the rears are modified. I had it towed to my house on saturday because it had sat for so long and I was worried about trying to get it to run. I hooked up a battery and checked some things. All the lights work and the ignition works. The gas was drained before it was parked so it would not start but it sounded almost like it wanted to. The battery had been relocated to below the truck bed so for now I am putting it back in the engine compartment.
I will admit that I feel a bit in over my head but I think with some time and some help I can have this thing purring again and then start putting the body and interior back together and getting the body work and paint done. If anyone knows anything about these cars or anything that might be helpful please feel free to chime in. I want to do this right for my friend and his widow.
That is sinister! Sorry to hear about your friend....lost my friend a few months ago also.
I know nothing about Subby boxer motors and the like or that car, but I'm sure the subby forums will get ya squared away.
Garner was an awesome individual, he didn't "Teach" me a whole lot, but he was the kind of guy that would say "think about how you could do it" really... He was a thought provoking individual, and I miss him
I am very glad to see his tools and toys live on though
Man, i used to love brats. A buddy had one when I was a teen and we swapped out the motor in a day. No lift, no muss or fuss, just wrenches, attitude and beer.
To bad we rolled it, hahahaha!!!
Best of luck with it.
Hey man I'm sorry to hear about your friend. That is one sweet ass subie he built. Go check out the forums over at Nasioc.com there should be more then enough info on there to get it all finished up.
I've been tinkering with this slowly, mostly just checking everything out and trying to get it to fire. The battery that was in it was an optima redtop which is great unless they sit forever apparently. Took it in to charge it and it wouldnt do anything even after sitting there all day so I am still hooking it up to the battery in my truck. That being said I made sure the gas was drained then poured a gallon or so in and tried to start it up. It fired almost immediately but didnt want to idle. I could gas it and run the rpms up but it wouldnt idle. I took the cables off and started looking around. I found a plug wire unplugged so I think that was probably the culprit. It sounded awesome when it was running though.
Next week when I get paid I plan on doing an oil change, flush the radiator (the fluid looks pretty bad), change spark plugs and clean the air filter as well as replacing the battery (probably not with an optima$$$) then I will see if she will run. I have crawled underneath a good bit and all the boots look to be in good shape and nothing seems to be leaking so I am pretty confident about its ability to run. I will probably be tearin ass for a bit with tags off of my truck and primer grey paint just to see what she will do.
Hugh we need to talk about that rollcage soon.
to charge the optima, hook it up to a regular battery in parallel, then hook it up to the charger. once it is charging both for a while, disconnect the regular battery and the optima will finish charging. The low internal resistance makes it necessary to use a regular battery so the charger can " sense" the optima. That or it is just a shit battery, since the plant moved to mexico all of them are shit now. If you really want a quality battery, get a Deka or Odyssey, they have always been better than the optimas.
Lets just machine a sweet battery box/hold down for the bed of the truck. Easy Access, still have good weight distribution, and I think it would satisfy Garner just fine. I mean, what you really gonna haul in that truck other than Ass
Haha. Nice. For now I am going to leave it the way it is but the battery in the Bed would be nice. It could probably go back where it was after I have it running well.
Now it wont run at all SHIT!
I pulled the intake and tried to feel the airflow. It doesnt seem to be pulling much on its own but I cant imagine that is the whole problem. I checked for spark and I have it. There is fuel flowing to the injectors but I cant say for sure that they are free. I don't really know what to check for these engines are so much different then what I am used to.
It has a mega squirt injection system on it and I am having trouble making sense of it. I posted on the nostalgic japanese forum but I figured I would post the question here too. Thanks in advance.
yup.. check compression, check timing, check fuel pressure at the rail if you can..
Brats are awesome.. my second favorite jap beater behind the Toyota Starlet..
thats really special man.. Im happy you have your buddies toy
There is actually a pressure gauge on the fuel line. It is at about 30 I can hear the fuel pump click on for a second when I first turn the car on.
I cracked the line at the number 1 cylinder and there is definitely pressure there too.
I cant really figure how to check the timing because the manifold and shit sit on top of where I think you need to check it.
I did finally start it with starting fluid directly into the intake after I took off the intercooler. it idled fine and everything seemed good, timing and what not sounded good. I need to figure out this fuel system because I am 90% sure that is what is causing the problem. (either bad settings in the computer or gummed injectors(though all four injectors being bad at once is not likely))
Thank you all for your suggestions and kind words.
So I have been doing a bunch of research and checking a bunch of random things and I think that I have this almost figured.
I have no fuel pressure anymore, I also found out that the megasquirt has a built in "safety" mech that only activates the fuel pump for 2 squirts and then shuts it off if the vehicle is not running within 2 seconds. If this was a bike I would just put a toggle switch to the fuel pump so I could control it but Its not so I am thinking I may need a new fuel pump with a higher Pressure in order to keep up with the demands. The lack of idle may be caused by low fuel pressure and this pump is the original 1979 brat pump. I am thinking about the Airtex E2000. I read on one of the 4x4 forums that they build good pressure and are available anywhere.
The other thing that I think may be giving me trouble is the Fuel Pressure Regulator. I know that it has its vacuum hose unplugged but I could not figure out where it needed to be plugged into until this morning.
I am going to try to replace both (1 at a time) and see what fixes the problem.
I also would like to clean the injectors. Does anyone have any advice on how to do this without ruining them? also would there be anything wrong with filling the fuel rail with injector cleaner and then turning the motor over? This should cause the injectors to open and spray the cleaner through them but will it do any harm to the motor or will it be affective at all?
Be careful with that E2000 pump, they tend to cavitate badly if you don't have it mounted just right. It will require a perfect amount of "gravity feed" from the tank to operate properly. They are also higher pressure than you might need, so double check the system requirements for pressure before hand. Some FI systems run on low pressure, some on high...
There is honestly no great way to clean injectors at home. You can check them for spray pattern though...
So I have been working on Garner's brat and I cant seem to make it fire. I think I have traced the problem to the fuel injectors. I pulled them today and 2 of them are cracked pretty bad. I plan on testing them to see what the spray is like but I need to know the impedence. so that I dont fry it while I test it.
So the numbers on it as best I can tell are 0979 and 4Y09D but they are very small and I cant read them well.
I looked the part for an 86 gl up but it doesnt look like this at all so I dont trust it. Here is a pic.
