The 186 is hands down the better choice. When you cut out the front crossmember just slice down the sides and About half way forward and down to the level of the base of the radiator. Take the piece you cut out and flip over and weld back in.
The sides of the support panel needs to be cut down, cut off the rearmost edge and keep. Slice off the same amount you move it forward and reweld the rear piece on.
Have you found an adapter yet, might be able to help you with a conversion plate and bits, unfortunatly it was a 6 cyl landy so the gearbox has different bolt pattern to a 4 cyl but you can swap the bell housings,it has a tired 161 holden fitted, ran alright but a little smokey and abit of a rough setup.
Its not mine but will make a phone call and send a PM.
Cheers Steve
Thanks for the offer on the adapter, I haven't found one yet but I have got another option of the wreckers apparently they have a couple, It would be a challenge finding (unless it's still got the bell housing the one you've got) the 6 cyl bell housing and then fitting it, If it was a 4 cyl I'd only need to fit the adapter plate to the motor.
Quick question for you Series3 GT - do you have an original 6 cylinder motor from the series 3 or is it a 4?
Just having a thought about removing my Holden 173 and putting the original 6 back in. If you had one, I could do you a swap for a good running holden red and conversion kit...
Just a thought...:)
The principal reason LR people have trouble with their Holden conversions is that they are usually doing it on the cheap. Appalled by the cost of reconditioning their Rover, they get a used Holden and put it in with the minimum of prior attention. They are replacing a worn out engine with a well used engine. Do it properly. A full rebuild, a more suitable cam grind, high volume oil pump, the correct sump and baffles for the job. Attend to the carburettor with a float bowl packer, pressure regulator, return line. You are taking an engine designed for low to medium speed family car use into an application it was not meant for. Things need to be changed to suit it for the application.
Yes I have a bellhousing to suit it but someone has fitted a landrover starter to it and knocked a hole in the edge of it to allow for the longer starter shaft, like I said it is a rough set up, if you don't have any luck elsewhere it will be here.

Bacicat- It's a 4cyl sorry, thanks for the offer though.
Brian Hjelm- I'm planning on doing a light rebuild just doing the rings and maybe a new cam and play with the sump and carby. It is only a farm ute with a tired 2.25 petrol and I'm just after a cheap reliable motor with a bit more power.
Klonk- Thanks again for the offer and if I don't find a adapter plate close by I'll let you know.
Hi all
Started this project 9 months ago with my son and had to stop, but now on again. The adapter plate I obtained was incorrect and not wanting to make the same mistake again. I would like to call on some advice and it would be much appreciated.
To marry the 202 to the S3 box (bearing in mind that it is a seized landi 6 cylinder coming out ) does the adapter plate and engine mounts need to be a certain type or are they all compatible. eg; 202/186 onto S2/S3 boxes.
I can get hold of a 186 adapter and mount off a S2 but not sure if it would fit onto the 202 and S3 box.:angel:
hope this makes sense.
Cheers
Bruce.
The 186 and 202 blocks are identical as far as the engine mounts go - as they are for all the red 6's so the engine mounts you have will fit the 202 fine.
Not 100% sure on any differences between the series II and series III gearboxes, but I would thing the adaptor or this should be the same for both.
Will be fine.
186 & 202 are same pattern. The boxes are also the same, but not sure about the rover 6 pattern matching the 4cyl pattern to bolt the adaptor to it. You should be able to swap to a 4cyl bell housing if needed.
