Knackered Engine - dilemna of what to go for next?

Indeed (mostly) and well done for actually looking at that discussion. However the 3/4 hub does have same weakness (sharp angles of dog keys cutouts) and also at least one of failures was a slider that is common across those gearboxes. - anyway this only cover total failure of the gearbox when in fact most will fail slowly by hammering the mainshaft bearing into the nosecone and 4 gear will start popping out. - and this is most common failure even when running 1600 engine. - so next time when you are bombing up that hill in 4th think of that overheating gear carving your gear housing.

 

So if it's a failure with a 1600 engine anyway its a moot point regarding Subaru conversions.

 

ignorance is a bliss

 

And just a few click's away

 

Subaru conversion coming soon! ........ I've bought a 2.5 Legacy (2000) 155BHP

 

I’ll look forward to following the thread

 

Going to keep the standard 1600 box, I've a spare if it doesn't last.

 

but it will fail catastrophically plunging the whole of the Western world into meltdown, oh... you've a spare... that's fine then!

 

The revs will be all wrong when you put that much extra power through a 1600 box.
When my 2110 went in with a 1600 box, I was in 4th gear very very quickly and 70mph was at about 4k rpm.
Changed gearbox for one with 6 rib ratios and it was much better suited to the increased engine power , 70mph at approx 3200rpm.
I went for a gearbox rebuilt by bears, but I now know this was a v bad decision & I should have gone for a more expensive one like @nobody s genuine 6 rib - rebuilt with nos parts.

Use one of the gearbox calculators to work out what revs you will be doing at various speeds, tyre sizes make a difference as well.

 

all the doom and gloom merchants are out today

 

Surely NOBODY would do such a silly thing

 

sounds perfect, my T25 is around 4k at 70

 

My post isn't doom and gloom,its just based on reality.

Fitted bigger engine, fond the revs were in the wrong place
Pulled engine, changed box, all sorted
I'd rather have got the correct gearbox when the engine first went in, as pulling it out again just cost more

I haven't said the 1600 gearbox will blow up and im sure it wont

 

May be fine for you and t25, I found cruising at 4k in my bay noisy and not as relaxing as it is now 70mph is at lower revs

 

Don’t you wear ear defenders ?

 

no i just use 4" foam and a thick duvet over the engine bay

 

Both @Sick Boy and I had our 3rd and 4th ratios changed to reduce the revs required in these gears.
