Guys,
I have a 1974 Series III 109 with original 2286cc desel engine with 4 spped gear box and fairly overdirve. (reasonable but hope to overhaul)
It drives quite well but a bit underpowered. heres what I want to do.
1) Install ex Discovery 1 200TDI engine adding / 110BHP with intercooler and oil cooler / upgraded exhaust manifold etc.
2) Upgrade front brakes to Disc (Standard adapter kit from Heystee) leaving rear drum brakes the same. (I know I will have to go to Dual system with new MC and I believe I have to add new pedal box and servo.
3) Fit power steering (More than likely P38 canabalised box ETC using 200 TDI Engine power steering pump
4) Also fitting Parabolic kit set and shocks
This will mainly be operated on road with not MAJOR off road stuff
Now the Question:
1) Do I need to upgrade differentials and shafts?
Suggested is to install pre 1992 RR/Discovery differentials.(to increase on road speed..which is good for me ).I believe these are direct bolt on's apparently and I will get off donor Discovery?
is this correct?
I know this will apparently loose 30% low gear box torque but that seems good to me if it goes a little faster on the road. Am I correct with this?
2) Can I leave my existing Series III gear box with overdrive (I want to overhaul these and any suggestions on kit for this and from who??)
The alternative is to put an LT77 / S into it and that requires a bunch of work as I understand it though it comes with engine?? iS THIS THE BEST WAY TO GO??.. please advise?)
3) Are the drive shafts etc ok...transfer case? to leave as is? Remember I will be upgrading front shaft to to disc brakes
4) Best kit to mate a 200 TDI ex Discovery 1 with original Series III gear box (90265225A) is bought from WHO?
Guys appreciate your response...I do build old stuff but this is my first landrover of this vintage..
Thanks
