    1979 Brat Dual Carb EA81 Swap

    Not long after my last post I ended up tearing meniscus pretty badly while rock climbing which lead to me having to get surgery and spend about 7 months in bed, having to do lots of rehab to walk correctly and gain mobility back in my knee. Unfortunately this also meant that I was unable to bend my knee enough to safely drive the brat as I'm 6'4" and barely fit in the thing to begin with. After about a year I finally got it back on the road, but not after some trouble with the fuel tank. So anyway on to the update of the car, I replaced the rocker arm which had broken a spring washer and started driving it a bit but had trouble with the car stalling out often and sometimes not starting at all. Turns out that after sitting the fuel tank had rusted again pretty badly and the sediment from the tank was clogging the in tank fuel lines. The fuel lines turned out to be badly rusted inside as well so I tried to take a industrial pipe cleaner to the inside which was a bad idea as the brush on the end of the metal line ended up breaking off in the line making the problem even worse. Unable to get the brush out of the line I was forced to make a new line in the tank. I did this using some 3/8" brake line I bent to reach near the lowest point of the tank, drilling a new hole in the tank on the drivers side of the tank, then feeding the brake line through an opening in the baffle. After a deep clean of the tank using vinegar and then degreaser with many flushes of water to make sure any gasoline fumes and varnish had been removed I brazed the new line to the tank. To hopefully stop future problems with the tank I sealed the tank using por-15 fuel tank sealer following their recommended procedure of prepping the tank with a degreaser and then their metal prep which is an acid based solvent to etch the metal and get rid of any of the remaining rust. new line by Luke Hoffman, on Flickr new line out of tank by Luke Hoffman, on Flickr new line in tank by Luke Hoffman, on Flickr On to other news while unable to drive the brat I was forced to get another vehicle big enough for me to fit in so I picked up this 1988 Toyota right before my surgery. I also started cutting up the donor brat I took the ea81 from to make a trailer out of it. Brat with CC2 by Luke Hoffman, on Flickr Brat with CC by Luke Hoffman, on Flickr Brat trailer project by Luke Hoffman, on Flickr After getting the brat back on the road I decided it would only be right that now that it was no longer lowered I would flex it out to check the suspension travel. Here are the results right as it started to three wheel. Flex2 by Luke Hoffman, on Flickr Flex1 by Luke Hoffman, on Flickr Front Flex by Luke Hoffman, on Flickr Rear Flex by Luke Hoffman, on Flickr Now that it's back on the road I've found some new motivation for it and will probably be doing little projects on it here and there. Some things I'd like to do next are a rear bumper and some mods to try to squeeze some more lift and travel out of the suspension. I also decided to ditch the idea of fixing the topper as I'm not a huge fan of how it looks and it was just pretty messed up with a rotten core and missing windows, so I cut it up and am hoping to make a fiberglass tonneau cover using some of the pieces from the topper. As far as the second gen brat trailer goes I'm trying to make it a capable off road trailer I can pull behind the Toyota or maybe behind the brat for camping and doing utility work, so I'm going to be building a steel frame for it with new suspension, haven't decided if I'll go independent suspension like timbren or leaf springs and a straight axle yet. I've also got a build thread going on for my Toyota which I'm turning into a off road camper on expedition portal if anyone cares to check it out https://www.expeditionportal.com/forum/threads/1988-toyota-custom-cab-build.207189/

    Wasn't able to get the brat going for the road trip because I found that I broke a spring washer on the rocker arm. But i did get the new rotor on and I got my rear drums turned, and the brakes feel better than ever. Took it out for some joy riding on some icy roads but immediately found out my alignment went wonky in the back because it was fishtailing and fighting itself bad in 4wd going straight over 25mph on the ice. Took it back to the garage and did a 2x4 toe plate adjustment and then used a drywall laser to double check everything. Now it's driving great, but I still have to replace the rocker arm assembly before I start dailying it again. Heres a random photo dump Header wrap by Luke Hoffman, on Flickr New Carpet Project by Luke Hoffman, on Flickr Winter Drive by Luke Hoffman, on Flickr Settled Suspension by Luke Hoffman, on Flickr Probably going to be taking it out of storage, washing, doing some more wetsanding and buffing to get the paint really looking nice this season, and then start dailying it again soon.

    I thought the brat looked cool and handled decent when it was lowered but not that I'm planning to use the car for camping and hauling stuff I decided to lift it. I made a lift for the front and clocked the rear torsion bar to get some more ground clearance, got a period correct winch, fully sound deadened the interior.

Gotta install a new brake rotor, check my valve tolerances, and try to fix up this topper. topper damage by Luke Hoffman, on Flickr bent window by Luke Hoffman, on Flickr The topper has some extensive damage and a bent window frame. The roof is made of a foam sandwich core which has molded/deteriorated and beyond repair so I picked up some plascore honeycomb material and fiberglass to remake the roof and repair the cracks.

    I've been dailying the car for about 2 months now and have taken it on a number of road trips about 2700 miles and it's been awesome. The one issue is the rear spring rate is quite soft.

    Got my bumpers painted with some single stage enamel yesterday and installed them today. Also found some old-school cal customs "off-road" light at the thrift store. I tinted them yellow and threw those on as well, still need to wire them up but I think they're pretty sweet for $5 lights with metal buckets and glass lenses.

    Here's a quick video of it, will be getting more in the future for sure. Think I have a small exhaust leak still, need to retorque it now that the gaskets have been heat cycled. You might have to click on the video to go to flickr to view it. Revs by Luke Hoffman, on Flickr
  7. Chevy luv struts and reclocking the torsion bar in the rear (also have to cut off a bit of the bump stop) and 2nd gen 2wd struts in the front with 2nd gen springs and cutting about a half coil should get you there. You probably won't even have to cut springs with a 15" rim. I'm on chevy luv struts 14" pugs with 2nd gen 2wd struts and 2nd gen brat springs (didn't cut springs).

    Thanks guys! I couldn't be more stoked with how it's turning out. Got the rest of my interior in, put the tailgate on, and drove it to the gas station and for a little cruise. Only a few things left to button up before I can take it back from the cabin and start driving and enjoying it!

    Well it's an important update. The brat is almost completely back together! The interior is almost all back together with the parts that I have, however it's going to be a work in progress for a while. Got my door handles and locks back in but still have to put the tailgate, more of the trim, and the cowl and wipers back on. But most importantly I took it out for its first drive since 2012, and it was awesome. It rides great and shifts great, Im still breaking in the engine and clutch so I haven't really stepped on it too much yet but it's got some pep. I would've taken a video but by the time I got the brakes done tonight it was already dark out.

    Got the front and rear windows, lights, front and some of the interior back together. I also installed speedoo clutch and throttle cables, the radiator and fan and made a pitch stopper by sleeving the ea81 pitch stopper to extend it slightly using the stock mount location on the body and welding a bit onto a the original mount plate from the ea81. Waiting on a single brake line for it to hit the streets. Have had it running and have worked a bit on getting the carbs synced but need to take it for a drive to really feel it out, AFRs were looking good when I've been running it and it sounds healthy and peppy.

    Sprayed another coat of base yesterday and then the clear today. So happy with the color and how the paint turned out, having never painted a metallic base coat before I was a bit nervous. Now there's only a few things left to get sorted out and I'm eager to get it on the road! Fresh Paint by Luke Hoffman, on Flickr Fresh Paint 2 by Luke Hoffman, on Flickr

    Got the rest of the exhaust fabbed up today, wasn't able to finish welding it fully. Exhaust is 1.75" unequal headers then 2 inch to the back with a resonator and a high flow muffler, all mandrel bends except the 45 right before the muffler.

    Got the basecoat layed this afternoon, color looks really dark in the shop but when it's in the sun or with good lighting it lightens up a lot. Body In color by Luke Hoffman, on Flickr Close up by Luke Hoffman, on Flickr

    Finally got spark after getting a refurbed hitachi distributor and then had to chase down a few changes that needed to be made from switching to an internally regulated alternator on the ea81. Once I fixed my spark issue and set the timing, I got the ea81 to run for the first time, and surprisingly it started right up and ran pretty well for not touching the carbs at al. I didn't get a chance to hook up the radiator and heater core yet so I've only run it a few times for a few seconds. The rebuilt ea81s first time running. I still have to make the rest of the exhaust so it's running open headers EA81 first time running by Luke Hoffman, on Flickr

    Little update, got it to turn over this past weekend but had no spark. Tried to diagnose the issue and I think I may have fried my ignition control module with my incorrect wiring at first. The ea81 sounded healthy when it turned over and it should be ready to run once I get the parts I need ordered, can't wait to hear it run for the first time.
