You can have a BW modified for firmer shift and it's good if your not making big power.
Anything over 150kw and your gonna need to go babyT/F.

How much are we talking for the BW firm-up lol

I paid $400 about 12 years ago.
Could be like $2500 because of GST.

Go the 904 an then get it tricked up.

BW35s are shite.

xcuse me, borg warners are good autos, we use them as anchors but please make sure theres no oil in them as we dont wanna put tranny fluid in the ocean, cheers

are 904s straight bolt in? i have a narrow block but if i get a wide block 2.6/904 i wont have to change engine mounts do i?

will the combo be longer than the 2litre/BW35 combo? do i need to change the tail shaft?

The 904 is narrow block only and yes they are a straight bolt in just make sure you have the spigot, flex plate and bolts to suit or you will end up with alignment issues.
