Quagmire Posted August 28, 2008 Share Posted August 28, 2008 Hi, I am in the process of rebuilding a 3.5 to go in my 2.25 powered 90. I have also acquired a long bellhoused LT77 ready for the swap but one thing i have not been able to find out is where the engine mounts will need to be? I am assuming (perhaps incorrectly ) that the gearbox mounts will remain in the same position, and that the engine mounts will end up further forward than the current ones. Does anyone have the specs on where the new mounts will need to be? Thanks Quote Link to comment Share on other sites More sharing options...
zim Posted August 28, 2008 Share Posted August 28, 2008 why've you got a long bellhousing'd LT77 ? is this one out of a v8 disco ? did you have a short normal 90 LT 77 before ? if it's a v8 box, then your engine will move forward. where exactly i can't say as i've not done one yet, but been experimenting on my hybrid.

Quagmire Posted August 28, 2008 Author Share Posted August 28, 2008 Long bellhousing so that i don't need to use adaptor plate and chop bulkhead as engine will be further forward. Proper job, much more like a factory fitted v8, and easier to access too Quote Link to comment Share on other sites More sharing options...
zim Posted August 28, 2008 Share Posted August 28, 2008 Fair enough. We've got an auto box (same sort of length as the box you have now) with engine out of a 200tdi disco awaiting fitting into a 90, and from our first quick measurements, the engine has to move forward a bit. engine mounts will be sorted once it's hanging in position. this is a v8 lt77 box bolted onto a spare 3.5 v8 (but not a 90 chassis): G Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted August 28, 2008 Share Posted August 28, 2008 engine mounts will be sorted once it's hanging in position. That's probably the easiest way - the engine sits slightly over to one side, and depending on the exact combination of vehicle, engine donor, drivetrain etc. the mounts will be slightly different. With the long bellhousing it will sit fairly forward, but ditching the viscous fan for electric can save ~6". Quote Link to comment Share on other sites More sharing options...

Quagmire Posted August 28, 2008 Author Share Posted August 28, 2008 Electric fan is sorted, as is the v8 rad. Both currently on the 2.25 as my old rad let go a couple of months ago and i couldnt see the point of getting another 2.25 radiator only to replace it later...

paul stage1v8 Posted August 29, 2008 Share Posted August 29, 2008 If you remove the engine mounts from a V8 chassis, rangie, disco, 110, doesnt matter, they go in the same place on all the chassis, the bracing web up against the spring perch. I had to change mine when I found the 'V8' replacement chassis I bought had diesel mounts on it. Quote Link to comment Share on other sites More sharing options...
