The V8 Owners Forum -

Maybe you need to post on a LR specific site such as http://forums.lr4x4.com

The questions you are seeking answers to are more that just a V8 engine - this is a great site on the V8 aspect but chassis etc information specific to Landrovers is a bit more sketchy.

Good luck with your project ...

yes what I want to do is put a V8 in 90 defender with no chassis mods etc, which ever V8 fits and works with exsisting axles will do, but if everyone says I need to change axles, gear boxes and transfers then it is then no longer simple. I would like to know which axles goes with which V8 etc etc ...

Not knowing anything about Land Rovers, I'd assumed it was quite an easy job to fit a standard 3.5 V-8 to a 90. But if going for a larger V-8 with a lot more torque, would likely have problems with the transmission, etc. Hi Dave yes what I want to do is put a V8 in 90 defender with no chassis mods ...

You seem to want black and white answers - unfortunately when modifiying vehicles everything is grey.

Maybe you would just be better getting a V8 90 and going from there and selling off whatever you have now. Hi there thanks for advice if were that easy I would but 90 V8s are like rocking horse ...

So if I understand this correctly the only difference is the bell housing because the TD5 is Different,(shoter) so I would need to get engine mounts moved (welded) or get a nice NEW chassis. MMmmm I wonder which it will be???

Well clearly there will be a number of other minor modifcations but the ...

Worth double checking, but I am sure the chassis will not need modifying. The V8 will fit up to the chassis just fine. The difference in length etc. is taken care of by the bellhousing and input shaft on the gearbox.

Chris. Thanks for the info, so you think the RR classic will fit straight in the ...

I understood the 90 also came with the V8 which ran the same running gear and gearbox etc as the TD5 - as mentioned the TD5 just has a different (shorter bell housing) so the input shaft is different.

So same brakes, axles, diffs, tfr case etc etc etc So if I understand this correctly the only ...

Defender:
R380 gearbox for manual
ZF4HP22 for automatic
LT230 Transfer Case with right side front axle output and the option for diff locking, depending on model.

P38A:
ZF4HP22 or 24 depending on model.
Borg Warner transfer case with left side front axle output. No diff lock, it has a viscous ...

If you already have a complete 90 TD5 - why not leave everything as is and just take out the TD5 and replace it with the V8 - leave everything else in the 90 as is.

No mucking around and the end result will be better than the mods you are thinking about.

IS that correct didn't think it ...

Thanks Guys
I knew this would happen, loads of ideas from everyone, it gets more confusing, So to do a straight swap into complete defender 90 I should use a RR V8 classic or a Discovery for the Axles. Is that a classic discovery or will any of them fit, and what is a PU, told you I was not a ...

Hi There thanks for replying, what I was wondering is, can I use "all" the parts from the RR, i.e. engine auto box and Transfer box, plus the axles, will it all fit? I can get someone else to sort out the electrics (hopefully)

Hi there, newbie to this forum,
I have purchased a 1999 defender 90 TD5,
I am going to rebuild it with V8, I know you are going to say WHY? but I used to own a 90 50th anniversary, and foolishly sold back in 2004 when I moved to France. So my retirement hobby is going to be be Build a new one, If ...
