Unless you find you've a 1.6 tranny fitted I don't think the transfer box is the problem. You should definitely be able to do 60 mph comfortably with a standard 1.4 tranny in.

My 200TDI ,(out of a Defender) is a replacement for the 2.5TD. Bubbles along at 55-60 quite happily if I push her up to 70 she starts to scream a bit so I rarely go above 60. Thats a 200TDI into a 1987 90 with no other Modifications. I have 15" rims but I cant remember the Tyre height.

I have a 200tdi in my '87 and with the 1.4 tbox it screamed at anything over 45 so I put in a 1.2 tbox and now it'll sit at 50-60 comfortably. Wonder what might be different? Diffs maybe? I think mine are standard but can't really be sure

That doesn't sound right i would have thought with a 1.2 tranny box it would happly sit at 80 +, my 1988 90 with i think is a 1.4 tranny box ( no serial no stamped or sticker ) will start to scream at around 65 and can easily carry on up to 80 so something doesn't sound right to me there.
there could be a chance someone has fitted series diffs for what ever reason or your tranny box is not a 1.2

Not sure about the diffs but I got the tbox from Ashcrofts and definitely makes a massive difference compare to before. How would I identify if I have series diffs?
Sorry for hijacking the thread, at least it's still on topic!

std diffs on a 90 should be 3.54-l meaning 3.5ish full rotations of the prop to 1 full rotation of the wheel, series diffs are 4-1 meaning 4 full rotation of the prop to 1 full rotation of the wheel, if that makes cense

Thanks, I'll get counting!

Mine's pretty nippy. When I had the 1:4 I'd just pull away in 2nd because 1st was too low.
My 200tdi came from a Disco and I've played with the off-boost fuelling if that helps.
tyres will be knocking the top end down a bit, esp if you do have a 1.6 lt230. faster acceleration though.

I need to take mine on a motorway run, I found yesterday that since I had my Injector pump throttle spindle re-bushed and resealed I can get a bit more out of the old girl and it doesn't sound as loud as it did before, Get up to 60 and acceleration is no existent though haha.
