Want to put V8 into where a TDI 200 is

[400HPONGAS]

So I have a 1993 200 TDI Disco 1 (early dash type) but somehow it came with the R380 and front and rear rollbars , wasnt I lucky !Anyway , the 200 has the Low oil pressure problem caused by the shifting of the Rear cam bearing . So Im going to replace with a V8 . Now the R380 has ths the 200TDI type bellhousing and Clutch .
Is it possible to change the Bellhousing to the V8 type along with the Clutch or will I need another,V8 style input shaft / thrust bearing arrangement/ clutch master cylinder ?
So if anybody wants the reverse conversion , that is V8 back to TDI 200 ill have everything you need , including Radiator/intercooler /altenator/pwr steer/air-con / .

Pity you are so far away as I would offer my v8 and LT77 five speed, from a rollover wreck, as a swap.

[400HPONGAS]

Thanks JohnF , Im not quite sure , but it might be possible to use the Bellhousing off a LT77 or LT77s onto the R380 . I wont be fitting a Rover V8 , so the old LT77 wouldnt be a goer anyway . The old LT77 wouldnt make it around the Block !!

Engine mounts on the chassis are different. You need to cut the mounts off and reposition them and reweld them

[Hymie]

What are you planning to do with the Tdi?

[400HPONGAS]

Thanks sclarke . will have to have a measure to confirm , Have you done the conversion ?
From a quick look at the Chassis mounts, it appeasr to me , to be in the same place longitudinaly , , but they do look lower than the V8 chassis mount so may only need a spacer ?

[400HPONGAS]

Good Question Hymie !!Im not sure , dont know is short answer . Seems a waste , as I just about fully overhauled it finding the low pressure problem .So now its got Serv exchange pump/injectors , altenator/pwr steering pump , new mains/bigends oil pump , vac pump , lift pump etc .To fix it ill have to pull the head and cam to relocate the rear cam bearing .

[HPLP]

Im doing similar in my 90. Ive taken out the 200tdi with LT77 and am replacing it with a rebuilt R380 and V8 EFI.

From what I have found out, I need a V8 to R380 bellhousing (FTC3922) and I need to make a smaller spiggot bush as the inputshaft from the gearbox has a smaller end to it.

Ive had trouble locating a defender R380 so thats the delay at the moment but that now may be sorted.

I hope thats of help.

For Mr HPLP: I've had a little experience with the spigot bush / v8 / tdi conundrum - A reminder if I may - if you've ordered a rebuilt defender R380, confirm that they have installed a v8 input shaft. Otherwise the diesel input shaft will need turning down or you can drill out the crank of the v8. In either case, you'll end up using the standard bush for either application. (If it was the other way round you'd have the special bush see http://www.aulro.com/afvb/technical-chatter/43344-using-v8-r380-tdi.html )

[400HPONGAS]

Sounds good HPLP , If all that is required is a Bellhousing off a V8 R380 , wonder if the throwout/thrust bearing arrangement / clutch MC is transferable .Still havent found out if the Bellhousing from a LT77 V8 wont bolt up to the R380 box .

[400HPONGAS]

Thanks langy , great article ,then the input shaft is the same in length for both the TDI and V8 R380 boxes ? , its only the spigott bush size that is different , Great , Im using a Holden V8 clutch / flywheel anyway .

Im actually building myself the box, but its getting very hard to get hold of a defender r380 with the correct selector setup. Consequently i'll have to build up from a scrap defender box and a good disco box the gearbox.

I was hoping to use the standard bush but turn it down (i heard to ~1mm) and fit it to the flywheel. Otherwise I'll have to fit the v8 input shaft (which Id rather not do).

[400HPONGAS]

Well it appears that the input shaft is totally different between a disco R380 Diesel box and the disco R380 V8 box ,Not only the spigott shaft diameter , but also the length is somewhat shorter on the diesel , and worst of all the gearing on the first motion shaft/input shaft is also different .They are not interchangeable , so it means I need the entire V8 box to convert to a V8.

[uninformed]

isnt all this a moot point as your not using a rover v8 anyway???? I would have thought you need something custom to suit your specific motor/gearbox choice???

[400HPONGAS]

Its not moot because nobody does an adapter for Diesel style Bellhousing ,so If I can only use the V8 pattern style to my Holden V8 because thats the only adapters around ,Now all I have to do is swap/buy a V8 R380 complete box.Id love to use a 4l60 T700 4speed auto , but no one does a adapter to the 230 Tcase

There has been some sucesfully made but nothing in production just yet;)

Oh, expect a build if you do use a 4L60, they soon fry in stock form

[400HPONGAS]

Thanks Rovercare , still the T700 is still more reliable and stronger than a 4HP22 , Ive allready got one from my Drag racing , suitably strengthed fully manulised with switchable lockup , wonder how it would go in a 4WD with 4000rpm stally !. LOL
You dont have a V8 R380 hanging around do you ?

Not hard to improve on a HP22:D

4k stall would be fun for a while:twisted:.....although you'd need one big ass cooler

No luck, I know a dude with a few, but all from tdi's, I'll keep my ears open though

[danny11987]

im in the process of throwing in a 308 where where a 200tdi is in a 93 defender.. any issues i need to know about, im using marks 4wd adaptor and a lt77 from a 80's rangine with matching lt230.

[Blknight.aus]

yes you need to know that I'll help you out with the fit up in exchange for the tdi200 :)

[Vern]

also needs to know that the lt77 will last about 3 minutes behind a 308:(

theres also 2 4l60e's, electronic T700 and later ones behind the gen3's, 2 different boxes

[400HPONGAS]

Actually theres only one 4l60E (VR VS VT and S2 VT with Gen3) commy onwards), the other one is a 4l60 (VN , VP) with no E or commonly Known as a T700 . The "E" just means electronically contolled ,As for strength , Ive seen them handle 1000HP easily albeit with the right modifications (And with a Transbrake !!) THe Early VN Box , is the one to go for as you dont need a BCM .
The LT 77 and the R380 are both 77 MM boxes , the 380 just has better selectors/synchros , 5th gear. (and reverse in the right place !!)Its not really any stronger .

Hi 400,
I agree with you about the 4l60e what car it suits but I am not sure if it could handle 1000hp. I haven't seen any information supporting that, only to 700hp but I could be wrong.
Stock 4l60's need to be beefed up a bit to handle the extra weight for the 4wd application. I had a 4l60 rebuilt, all new 5 plantery gears, kelvar bands, new sun shell, servo's etc etc to handle 650-700hp with new convertor for $2300, very happy with the box and the way it performs under load, it still has a very positive change between gears.

I also read in this thread someone is putting in a 308 TDI. I think he might be a little dissappointed with the power he might have to supercharge it.

Within the Australian market you also had the 4L65e which was used in the HSV's behind the early ls motors (Also behingd the AWD models too I think). It had a 5 gear planetary set standard (as opposed to 3 gears I think) and is a popular upgrade amongst SS owners starting to push out higher power levels.

Hi guys,
Been following this thread trying to figure out if this is possible.... I have a v8 range rover that has had the lt77 previously. I still have the lt77 bellhousing if i need to use it. I'm looking at buying a R380 from a Defender 110 that was behind a TD5 that comes with the bellhousing etc. Can I use my existing Lt77 bellhousing onto the gearbox or is there shaft length issues etc? Is this possible, what exactly will I need?

Thanks guys would really appreciate some advice!
