Nice Find... The Flexible flywheel design probably answers the question I had earlier about why the flywheel I had to replace in my B4 Which I thought was standard was in fact a two piece type rather then a single piece. I can vouch for the original two peice taking up a lot of the engines vibrations cos sure as shit the new one transmits all the harshness

By two piece/flexible, are you referring to the Dual Mass Flywheel? I've heard they're more trouble than they're worth.

DMF sucks... Solid FTW!

[B4TT]

I am assuming that its a dual mass, all I know is that the front section (the contact area for the clutch) bolted a a secondary peice at teh rear and I assume there was something in there to take out some of the vibration, I have pics somewhere il have to locate them. I have the single peice from a WRX in the lib now and it is significantly harsher as far as engine vibrations go.

[Soop]

Apparently the DMF's aren't all that flash for other reasons. Which I'm sure Chris can elaborate on.

For a start you can't machine them, I had one in my old patrol and it had to be replaced rather than machined when clutch replacement time came around. They do take a fair bit of vibration out though. I only replaced mine as I had the engine out, the clutch was still OK after 280,000km, not bad for a 2.4 tonne 4WD ! Paul

Guys the B4 does not have a DMF, only the RX and Heritage's from memory.. as a WRX flywheel and the B4 flywheel have the same part number in 03

[B4TT]

I know that it shouldnt but seriously dude I can post a picture of mine up and show that it was two peice, tis a freak. Any luck on tracking down a gearbox for it?

[XXB4XX]

So far, I have realised that there are still good people on this earth.

An RX box will be fine, I ran with one for AGES and I still didn't break it LOL But you can't use them in your B4 without work (Flywheel, master cylinder and box and maybe peddle)

[Soop]

Aren't the RX gearboxes 3.9:1? If they are, he'd need to get another diff as well.

[XXB4XX]

out of curiosity, what about a MY99 rex box?... will she love the B4 long time and let the car make sweet love to it, without any mods? ...... uleh?

[Soop]

Will be fine. Just confirm that its 4.11 ratio and your sweet. Any Subaru gearbox that is 4.11 will work.

[XXB4XX]

it's 3.9 ratio from what im aware of.. Once again, I owe all my knowledge so far to D_generate.. best bloke.

[rxliberty2000]

My RX box was a 4.11 And as far as I know all gen 3 RX boxes were the same.

[XXB4XX]

well..

thanks to having some lovely sexy ass mates..

I got a deal where Im getting my box rebuilt, by a very reputable gearbox place... for a VERY cheap price..

I mean CHEAP...

fingers crossed for now..

CHEAP

[d_generate]

I'm 98.7% sure all "Aus" WRX boxes up till at least MY00 were 3.9 with a step down to 3.54 rear diff. Good luck with the re build.

[XXB4XX]

Cheers man.. and once again, thanks heaps for helping me out

[Soop]

Ah yes, my bad. Pre-99 JDM WRX's had 4.11. Sorry .
