since i think i'm pretty well set on doing the ej20 turbo conversion on my rx, i'm trying to check some of the info i've found.

from what i can gather, a turbo engine from a forester is an 8-bolt gearbox design. is this correct?

the turbo ej20 forester is a 99+ model? I can only assume the forester engine is actually an EJ205

it also appears to be correct that even if it is an 8-bolt design, it still works with the newer 4-bolt design (ie not our EA82 4-bolt design). is this correct?

none of those things can i confirm anywhere without any certainty. thanks guys

I have read that the 8 bolt engine's/gearboxes will bolt up to 4 bolt engines/gearboxes - the early EJ 4 bolt design are the bolts that are used when "mixing" the two generations of gearbox and engine...

That's all I can contribute.

thanks...

now i've been given some more, and rather confusing, information from an engine supplier. he reckons the ej20 turbo that works with the forester gearbox is actually a 6-bolt engine and the 4 bolt engines finished in 1998.

is this all just rubbish? he's just calling it a 6-bolt when it's really a 4-bolt with some un-used bolt holes? and does that also mean that there are newer 4-bolt engines than 1998? i'd really like an engine that's around 10 year old for my engine swap

As far as I know there is only 4 bolt (pre '98ish) and 8 bolt (newer). I've got a 4 bolt '93 EJ20 turbo connected to an 8 bolt '04 Forester dual range gearbox and it works fine. As far as I know, any of the EJ series engines and gearboxes will bolt up fine.

yeah that's what i thought too - i think the person selling the engines has a few dodgy issues. however, i've been given a great deal on a later version TT engine. might be just looking at that as i know it's going to work
