Has anyone got a EA81 Turbo in a Brumby?

Buddyboy · Post by **Buddyboy** » Fri Jul 20, 2012 7:09 pm

Just wanted to know if anyone has done the conversion and put an EA81 Turbo Engine into a Brumby? I know that there are plenty of Brats running around the US with EA81 Turbos, but wanted to speak to someone a little closer to home. Regards Buddyboy.

what happened here?

Changed my mind, re the link above, I have a low kilometre EA81 Turbo sitting in the shed, picked up a cheap ECU and harness, so it would be stupid of me to now not use that Engine. That's what happened there. Buddyboy.

that's fair enough then

best of luck with the build. I'm still working on getting my brumby registered

I have ... the intention to 'just' dump an EA82T into my Brumby. Started by buying an L Series GLTA as the test bed for my straight gassed EA82T, just having trouble in seeing why i should strip it for the Brumby now, 70,000km later, am still convinced EA82T is a good and reliable engine and will have enough power for a driveable beast without over doing the power thing.

My Brumby sits with a scalloped cross member for the turbo pipe, pisser bottle shifted to clear the EA82 dizzy .

Go fit ya donk and take us with you through the install, any problems etc .... what are ya worries ?

I have a wagon with it in and the brumby would be relatively easy conversion too. Just exhaust, fuel pump and wiring really.

I had a wagon that i put one in, it just bolted straight in, only thing i had to do was flatten out the heat shroud on the exhaust manafold so it didn't touch the crossmember, think i even put a 5mm spacer under the driverside engine mount to give it a bit more clearance.

I had mine running on a Haltech computer so wiring was easy and scored a wrx fuel pump to run it, the Haltech didn't need the airflow meter so only had to move the battery for the pod filter, also used a RX turbo radiator which was pretty easy to fit..

Mine did have problems with the hydrolic lifters as i had a different cam made for it, but the standard solids fit..

RX turbo cylinders fit these as well if you need to rebuild it..

The ea82t is pretty much the same, you can even use the original gearbox, you just need to get a new clutch plate made with the 82 plate and 81 centre..

Its well worth the conversion, still got plenty of power with a big exhaust, mine used to kill 5 litre commodores off the line and easy to get it engineered.

If anyone had a good ea82t they dont think is worth putting in a brumby i'll take it off there hands..

Cheers..

mmmm, I have that problem in that I can't kill anything of the line

I am also thinking EA81 and EA82 turbo have same power/torque characteristics.
Love to see some detailed pics of the EA81T

After seeing tweetys SC EA81, I feel like buying a brumby just so I can fit a supercharger to it. Id cut the manifold up so I can mount the SC low, almost directly above the block so it fits under the bonnet.

This is what you should do Jon, supercharged EA81 on gas

Make sure you have it dedicated to gas.
You will get so much more power as you can advance the timing so much.

My main questions are:
What type of Fuel Pump to use, I've read that you can use a Bosch 0580464070, Morrie has suggested using WRX Fuel Pump, which one would be the easiest, bearing in mind my next question?
Is there a larger Fuel Line and Return that is an easy swap over that I could use?
Using larger Fuel Lines, I assume that the connections to the Fuel Tank would need to be larger also, has anyone got any suggestions how I go about this?
Three are three (3) vacuum lines???, I think, running along the top of the fuel lines, over the engine. They appear to run from one side to the other. Any suggestions what they are and where they go.
That's all for now, I'm sure that there will be plenty of more questions.
I have also moved the Spare Tyre to the Rear Tray and Battery to where the Spare Tire used to be. Regards Buddyboy

Its not necessarily a larger fuel line. The fuel pump pressures for EFI and carb are very different, Carb is like 3psi EFI is much higher. So what you need is EFI rated fuel hose that can handle the higher pressures.

I used a generic efi external pump from Nardek on my L Sedan , it had a 1/2" intake to suit the tank supply hose and standard outlet to suit the 8mm ?? lines to the front. Your brumby tank outlet is likely just the 8mm , need some adaptors maybe or get efi pump with 8mm in and out ?

If you look at the front fuel filter think it has a return line so think it is used for the fuel return after the fpr. I had these similaar concerns and concern went after seeing a dude repiping his mazda 323 to powwer up his turbo rotary with flexible aluminium just bunged up along under the floor and clamped into place.

Must be easily available

Just no time/$ for Tweety like projects unfortunately

I did mine a long time ago but i'm pretty sure i just ran 1/4 Goodyear rubber line from the tank to the pump then all the way to the engine, used the original return line.. didn't mod anyhthing, worked fine no fuel serge.. i just kept everything simple and i worked great.. i only had 1 filter, was a generic efi filter, had it under the bonnet on the firewall..

Thanks to one and all, the project has come to a sudden halt, I've done my back in and unable to do too much at the moment. Although, it will give me a chance to read the Manual on the EA81 Turbo Engine that I have purchased from the US. Regards Buddyboy.

bugger mate - crook backs are not good! Very crippling

Once you can start to move again get some work done to your back (regularly) and do the stretches etc that you're told to do. I'm still doing mine and the last time I saw a physio was probably a month ago now - that was for a back issue over two months ago!

All the best

If you are selling the EA81T Buddyboy, let me know?? That would be a lot eaiser for me than going down the SC path like tweety. Probly not as fun though

Mechanically and room wise maybe, but there's a wiring loom you'll need to get in the package too - then work out how to fit it to your VW... Thought about going with an EJ22?

Sorry for the off topic question!

Sorry Vino Dubber, the EA81T is not for sale, as you know there are like Rocking Horse Poo, Guy that imports them from Japan is named Greg, and his Company is Called Rolin Imports, here on the Gold Coast, you never know when he could stumble across another one.
Thanks for the advice re the Back El Fredo, but the time for stretching is long gone, it's now a case of waiting for the Knife. Regards Buddyboy
