Looking for advice and/or ideas for a 4bd1t conversion project

[headdamage]

After years of looking for a good forever engine for a Rover I have stumbled onto a low mileage engine and transmission from a 6x6 Perentie. Not a common item to find in North America.

I currently have an exmil LHD 90 (currently no engine it it, the 2.5na came out and I'm putting a 200tdi together to go in it) and a factory 1993 200tdi Range Rover Classic four door SWB that I have converted to LHD.

I was intending to build a 110 for the Isuzu engine but I have just accepted a job offer in a place that I might not have access to a garage in future so I need to consider doing something quicker to take advantage of this engine now.

Would putting a 4bd1t and LT95 into a 90 be a practical option or would it be too big and/or heavy in someway?
I assume I would have to find or fabricate an LT95 type seatbase/tunnel cover as my current unit is for an LT77/LT230 combo. Is there a risk of the prop shafts being too short with the LT95 in a 90? Is the 90 chassis strong enough for the 4bd1t?

Would putting it into the RRC be a better option?

Thank you for any input.

I'm located in Alberta Canada if that makes any difference.

It will fit great in the 90, the same as it would a 110 or RRC. Prop shaft lengths will be fine to, no real difference than the lt77/lt230 combo.

Only real fab work will be engine mounts and try find an early 110 trans tunnel.

Chassis plenty strong enough.

Do it, it will be a great combo

Off the top of my head youre only adding about 100kg and a reasonable.chunk of that is in the gearbox.

Your biggest issues will be.

1. Making the mounts
2. Setting up the cooling sysytem (use thermofans)
3. Propshafts (different yolk flanges) and exhaust
4. Wiring for the cut off contol for the injector pump.

If its a complete 6x6 box and your putting it into a 90 im interested i getting my hands on your boxes rear axle output assembly.

Its a brilliant engine and gearbox combo. Do it.

And yes any.shed class or chassis/body build landrover will take the suzi and the 95.

There will be some floor and firewall work reqd but the v8 couny/defender that took the lt85 and 230 has the same basic shape tunnel and those made it.to.the US. Theres quute a number of them out there so ylu should be able to get someone to measure.one up for comparison.

Dont forget to t the brake vac line for the cdl actuator.

If you need to have it engineered or complianced I think you find a 90 fitted with a 4BD1T will exceed plated front axle capacity...I have a 130 4BD1T (bull bar & winch) and I'm within 200kgs of my plated rating (measured for engineering report). I believe 130's have a higher front axle rating than 90 & 110's.

There is nothing similar to having an engineer check the vehicle configuration/modifications here. Only basic safety checks for the operation of safety related items like lights, brakes, steering, windshield glass, etc...

However, I would not want to do anything that was unsafe or outside of the design capability of the vehicle. There is no difference in the front axle of the 90, 110, and 130, rovers that I've seen so I don't think strength of the axle is an issue from a safety or load stand point but I could see the there being an issue with the change in weight distribution hence my posting this tread and asking.

Given the fact I've never come across one of these engines and transmissions in this configuration here in Canada in over 30 years of being into rovers I think I'll hang onto any unused bits just in case I ever come up with a use for them. Maybe add third axle or a powered axle trailer to the 90 some day.

Plated max axle weights vary, doesn't mean the axles are different....springs and chassis probably shoulder the change in Defenders.

I think it's 1250kg for 90's and 110....1580kg for 130's. I know if I was installing an Isuzu in a 110 and not my 130, I would have got knocked backed unless I could swing a front axle weight upgrade or modification past my engineer. I'd be interested to see what the Counties are plated at for axle weights.

A 90 with an Isuzu would be a little weapon, I'd like one, but wont happen in the state I live in. Slightly jealous of your registration process!

Early deefers counties and discos have higher axle loadings and gcms than later ones.

I think 91/2 when abs became an option was the change point.

My 90 is built from 1980's vintage military parts and I've up graded the diffs, axle shafts, and slevied the axle casings. It as has a safety devices roll cage and I will likely convert the rear drums to disk.

Picking up a rough exmil 110 with a good 200tdi in it. I'll take the 200 out and put it in my 90 then strip the 110 for a restoration and 4bd1t lt95 transplant. I've got the engine and trans mounts and a friend has an Lt85 seat base and tunnel for me so it should all work out.
