For the l series box, on a simple way, can someone please describe what is needed to make them fit?
Yes I have read through other posts but it's all a bit complicated.

Cheers Cam
From what I've gathered so far for when I convert mine one big issue is the tailshaft (L series being 2 piece, fitting a center bearing carrier to the car) If you don't have any body lift you might need to bash the trans tunnel a bit. G/box mounts are slightly different between the two, some mods needed there, You need a combination of flywheel/pressure plate and mod the pedal box to suit L series pedal and cable. There's also the shifter linkages which some say need cutting and shortening but others have done it without changing them.

Cue Jonno, he's done at least one of these conversions ;)

Stop scaring the little guy....first step is buy a $100 - $200 L Sries 4WD that you can test drive - this will give you all the bits, plus a foot of 6mm bar 40mm wide and some bolts

Excellent!
Thanks Jonno, il keep that in mind.
Oh, obviously you take the diff, what about driveshafts?
Now to quietly start looking for an l series.
The only problem with this is that I don't think mum would aprichiate another car.
And after driving it I might want to keep it as one car.
Sh!t, I think I have subaruitise. Hahahaha.

you might find yourself falling in love with the 4sp. especially with the low end torque of the ea81 the 4sp utilises this better then the l series 5 sp

Good luck finding a driveable L series for $100 in Adelaide! :o I think the driveshafts are the same between the two, same spline count.

Put out feelers - I have had people ringing me ! The Subie dealers parts fella chased me up on one customer heading back OS with a sweet Touring Wagon with a stuck thermostat - 3 weeks rego $250 some years back. Last one was dirty filthy and drove it home to - $100 owner not wanna fix the head gasket.
No need the CV shafts unless you are going the bluesteel track. Just the bits in the middl fly wheel back - rear diff only if ratio different to yours, console bits and shifter bits. The $100 one came with new near starter motor :)

Ok cool.
More problems.
One of the threads for the head studs came off. Could only do it up finger tight.
The others don't look the best but are holding. We have taken them all out and are going to ring the engine builder tomorrow.

oooooh stripped head stud? that must have been a horrible feeling :|

Could you get the studs out of the block? If so replace that one at least, probably best to do all of them if you can since they stretch every time you tighten them up.

Brumby Kid wrote:Umm we were going to go 10:1 but I think it was just a bit too much.

Yeah ea82 with timing belts and that.

Phh put an ea81 in. No cert needed.
I chose to keep it on 91 for two reasons. Cost and availability. We were thinking about 95 but that is the hardest to get. Even in surburban / city areas let alone the country.
And 98 is way too expensive for me.
Yeah if we upped the compression and ran on 95/8 it would have given better performance.
But I didn't wanna have the extra fuel money, and don't think il need that power. It's the only thing power wise we haven't done yet apart from a snorkel.
Soon.

Cheers Cam
EA82 are known to have weak timing belts?
Or are they just a PITA to change, as I found out in April? :p

Really?
Maybe an EA81 is a good candidate then. :???:
Does EA82 have any advantages over EA81,
other than higher peak power and peak torque ratings?

Do any EA81's come with air-conditioning and power-steering? :confused:

Fortunately I don't have to rely on my L Series much anymore.
My L Series is more of a play-thing now. :)
I want bigger tyres (205-70R-14 or bigger)
and I like driving at 15psi when in soft sand, so I need more torque.

littlewhiteute wrote:It's not just the compression ratio.

It's the combination of CR and combustion chamber design that determines minimum octane.

The EA81 has an inefficient wedge/bathtub 2 valve chamber that can't compete with modern 4 and 5 valve semi-hemi heads.
I know. I've heard of people reshaping the combustion chamber to resist detonation.

My 2008 Civic has 10.25:1 compression and is meant to be run on the lowest-octane petrol.
Better combustion chamger design and/or computer fuel/spark management.
