1979 Brat Dual Carb EA81 Swap

Recommended Posts

Got most of the wiring, heater hoses, vacuum lines etc figured out and continued working on my headers. The engine is almost ready to start, just have to get a nut and bolt for the alternator, get some hose clamps for coolant lines and then I will have everything I need to wrap up the drivetrain. Also have almost the entire brake system back together, with all new soft lines, just have to get a piston compressor because my drivers side caliper won't fit on the rotor with the new pads.

 

The engine mocked up with coolant lines and vacuum lines, waiting for hose clamps for final assembly.

Heres a photo of the headers. Still need to put another short length of pipe on the end of the headers and weld on a flange and bung for my wideband but I'm pretty happy with how they're turning out

Thanks for sharing! It's very inspiring to me as I have to do majority of what you have already done. Question, how did you go about smoothing out the dented wheel wells? Mine are also super dented and I would like to smooth them out like yours. Also, if you ever want to get rid of your old wheels, let me know! I want them!   ;)

To smooth out the wheel wells I started using a hammer and dolly to knock out some of the big dents from inside the wheel well, but because there are multiple layers of sheet metal in place it is impossible to knock out some of the dents. For what was left after using the hammer and dolly I just went over with some body filler and sanded smooth. Best of luck with your project!

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.

DITCH that Nippondenso distributor, and get a Hitachi. That is what all the later 4WD models would have anyway. The Nippondensos will leave you walking, ask me how I know! The Hitachis did have issues with the shaft bushing wearing out, if the oil wasn't changed regularly, but the electronics are bulletproof.

 

Excellent work by the way, superb job!!

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

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.

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!

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.

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.

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!

Some beauty shots from tonight :)

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.

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.

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.
