7 series conversion advice

gibbut

So, i have 4 x 7 series cars,

swedish 1984 760 gle, in MINT condition, paint, interior and body 10/10, one previous owner, 300k km. this is the car I wish to continue with. ( sweden )a belgium made, b200e 5 speed manual, good motor and drivelinea swedish 1985 740 turbo b230et, good auto, only 106k kms, but pretty tatty from being left in a paddock for years, motor has a knock. car has a nice size ( possibly standard? ) garrett turbo, 2.5" dump pipe, external wastegate, and 2.5" exhaust ( sweden ) a 8/1988 740 turbo wagon ( belgium made ). b230ft motor is a volvo factory exchange with tag on the lh side, showing 30 thou over, and bearing sizes. not sure on if the auto is any good, but the motor runs amazing, has a tiny turbo ( maybe mitsu? ) ( cant see a K on the block? )

now, is there a particular motor, trans, turbo,

diff combo above any experts recomend I run with, or advice, problems, i may run into?

im pretty sure ill go with an auto with the spring hack? as I have been told the 5 speed is made of cheese?

any help appreciated!

Sounds like a nice combination of cars (and choices!) How's the interior and exterior on the 740 Turbo wagon? Assuming it's not great or that would be my choice to do up! :)

Given you want to use the 760GLE as a starting point, the easiest thing to do would be swap in the B230FT and auto from the 740T. You'd have a nice cruiser and even with the auto and small turbo, it would go well and cost would be minimal. There will be a bit of mucking around with wiring harnesses as the 760 is probably not LH2.2 injection like the 740T??

If you prefer manual, pop the 5-speed behind the B230FT. As long as you're running stock boost it shouldn't explode if you're nice to it! More work of course...have fun!

Tatty one with big turbo gets a refresh to fix knock and goes in the wagon and its turbo motor goes in the 760 ?

Put a Ford 5 speed box behind the big turbo one,conversion detailed in this forum many times.

FWIW, the spring hack is only relevant to the AW71 box if you have one of those.

What year is #2?

Big turbo off et onto ft, ?

Ft and its auto into 760

What diff you guysc reckon. Any idea what ratios theyd be

ramrod

760 3.54:1 or 3.73:1 same with 740

1985-87 700s are prone to front crossmember cracking.

Pre-1988 wiring looms may be problematical (due to the wire insulation plastic disintegrating).

Pre-B280 V6 engines are problematical.

ZF auto transmissions are problematical, best replaced with AW71.

K-block B230FT should be okay if it has the 13mm rods.

Manual transmission (therefore pedal box and RHD manual trans centre console trim) is not very common any more in OZ.

Diff ratio is on a label on the diff.

USB parts manuals &/or a collection of Green Books are highly recommended; there were a lot of running changes and some electrical wiring differences.

The early 760 have different strut top plates to the 740
