Looks like EA81 & 2 turbos were different.Anyone say what the differences are ? I seen reference to VF 2 and VF4

who made subarus turbos ?

any info appreciated, thanks

OK , seen rsrlegacy reckons EA82 turbo fits with minor mods

any info to be shared between the models? any tips or advice welcome

I did have some offer a long time ago a larger diameter exhaust off some race EA82T but would require spacing up my engine mounts to clear. Given the five speeds shoved in that might not be a good idea.

pipe specs knowlege appreciated too , ta

Jono, welcome to the addiction

If you are not concerned with legalities and really want that sweet turbo music to go, the simplest option is to get an EA82T and matching 5 speed.

Only drama is you have to 'massage' out the chassis rails about a half inch ? to make the heads fit. ell, the first real car work I did was this exact swap into a Brumby. True I had a fair bit of hand holding from Steve, (cheers

) but I got there in the end.

If you run an intercooler you can run up around 15 PSI all day. Your problem then becomes getting the power down to the ground. For that you need to track down an EA AWD gearbox.

Just out of interest, in 14" 70's I was running about 4 PSI at 170 kph continuous up through the NT with no engine hassles. I did manage to rub the outside shoulders off the tyres after 500 odd k's so I guess there was a bit of flex in the front suspension somewhere. Heinous fuel consumption though, around 20 l/100k's on gas.

And it takes an AWFUL long time to slow down again....

There are more elegant / time consuming / expensive and Legal ways to get the same and better HP if you are interested.

I reckon your LPG EA81 turbo sounds like a swell idea!! Really tops.

You can use the EA82 turbo exhaust manifold and turbo - in fact it should be perfect! You will need to mod the engine crossmember though.

Turbo?.....HELL YEAH

I have been bitten by the bug also !

Hmm, sounds interesting jono, you will however have to modify the crossmember on the right side to allow clearance but its not to hard, the front of the crossmember has to come down about 3/4" on the right side or from near the engine mount to nearly the upward bend that connects it to the body, cut, shape and mig weld it, (arc is too savage), l patched mine from the inside after doing this, had to keep the engineer happy.
You can use the 82 turbo exhaust manifold and the turbo, it all just bolts on, the only difference between an 81 & 82 is on the dump pipe side, different stud pattern, but you mentioned making your own so this should be no problem.

Boost is addictive, there is just no going back.

I heated the crossmember up with a blow torch and bashed it with a four pound hammer, not subtle and not as much clearence as a proper job would yield, but it doesn't touch and didn't take long.

Thanks guys. I'd better start collecting some bits.
Fuel consumption increase ? I know a fella who gas turboed his Spectron and got an extra 80k out of his refills ! So only time and experience will tell.

I like to stick to EA81 thanks all the same, but don't mind the idea of EA82T stuff.

Alrighty, thanks to Redskin I have some big KB photos on file of his cross member mutilation to guide me in my own mutilation.

Don't mention it Jono, my pleasure, by the way, don't know if l should mention this but here goes, l do have a spare engine, ( EA-81T ), it's mostly complete and is in need of a complete rebuild but heads look fine and the fuel injection system complete so if you get stuck but still want to turbo your car l will make it available to you if you want it.

if your selling an ea81T i'll buy it.... if you decide to sell and if jono doesn't want it

steptoe · Post by **steptoe** » Thu Mar 23, 2006 1:36 pm

Thanks Redskin,

I can't use an EA81T engine coz I am running an EA81GASLPG, so efi and heads and stuff no use to me, just chasing a turbo at the moment.

it is the thought that counts tho ain't it ?

I've got an EA82t exhaust crossover header and the ihi turbo if you want them. The turbo will need looking at as it came off an engine that dropped a bigend. But if you want them they're yours.
The replacements are a TW equal length header pipe and a gt28!

thanks, sammynb, sent you a PM

Any pics? Like to see how the equal length header pipe fits for room. I want to do this to my ea82T.

I don't have any pics at the moment but I will take a couple sometime in the next week or so so you can see. Obviously it becomes tighter in there but it's not to bad.
If you are interested these are the guys who make them:

There is a pic in reply #7 in this thread from USB:

Just don't be wanting to get to the banjo bolt for the turbo oil feed on the crankcase as it's a header pipe off repair.
Stainless and delivered from Canada for $900.

Jono, I didn't get your pm. Try again.

Thanks sammynb for the links. Having read all that, I think for me just to redirect the RHS for better flow would be suffice and a lot less hassle.

I am wondering if to cut up stock EJ20T front pipe would sufficient to adapt just for the bends etc? Can anyone shed some light on this as I am not familar with EJ's?
