    Default Introduction, and help request for Toyota 4Y on series.

    Hi all,

    I'm a 48 y/o guy from Spain, owner of a rare 109 Santana six cylinder straight diesel, made in Spain. Also owned a Spanish military 88M, and have a VM 1991 Range Rover that issuing restored.

    Because of destiny and COVID I'm stuck in China, Shenzhen. And as long as I have time and my family is far, I decided to do something "fruitul" and bought one of those brand new 4Y engines which i think they are among the best possible options to insufflate new life and reliability on an old Land Rover. No, I'm not thinking on desecrate my venerable 109, but on purchasing an old LR 88 and fit the engine on it once I'm back to my homeland. Googling for information I found this forum, which seems to be one of the most extensive places on earth about mechanical creativity, so I registered because I think that maybe here I could find someone who could help on how to proceed to to this swap.

    Basically I would like to know which parts are needed, if anyone has a design of the bellhousing adapter, and what are your impressions on the car with this heart. I have plenty of manufacturers around, so for me would be very easy to make all the adapter parts here, with good quality and service, so if I can have them done here before I ship the engine to Spain, that would be amazing.

    Of course, in return, you can ask whatever you want, and I will post pics of the process and so on.

    Thanks in advance!

    Hi Barbarin.

    As Johnnok says wait for Mr Frank's response. He has knowledge on the matter.

    Check out gilo engineering website.
    I know they had an adapter for the 2.4D.
    Same bell housing bolt pattern as the 4Y engine (Toyota)

    Keep in mind series gearboxes have a different pattern for the bell housing bolts some start at 12 or 1 o'clock.

    Speak and send photos to Gilo. Think they can also advise on clutch etc.

    Good luck

    Thank you very much, gentlemen.

    I'm working hard on this... my ultimate goal is to make a complete set pf parts for a problem free, no worries, swap. Probably the 4Y-E s the best option for the Series.

    Thanks !

    There have been various successful engine conversions on the Series Landies:

    - Rover V8 using factory items (Stage 1 3 Series)
    - Nissan RD28
    - Ford Essex V6
    - Toyota 3C
    - 200TDi
    etc

    Saying the Toyota 4Y is the best is a bit presumptuous.

    But is it a pretty decent option.

    Well, agree. Probably this needs further explanation. For me is " the best" when it comes to value for your money, and specially if we focus on a solution that could be industrialized, being able to provide on a single pallet all the parts you need from exhaust adapter to clutch, to fan shrouds.... as nowadays this is an engine that is still being manufactured and you can find easily parts anywhere. Most series, at least in Spain, are enjoying a second life, in which fuel consumption is not a big issue, and people don't mind to pay more gas in exchange of other benefits that petrol engines have.

    Regards

    A 3,5lt 6 pot diesel.... pretty scarce beast (I’ve only seen one in the UK)

    That was when Santana did the “what if...” and added 2 more pots onto the 2,25?

    Dunno why you would change it but the 4y (70kw) is a pretty good choice. The 4y-e has got a bit more electrics but will give better economy (.....)

    The Gilo adaptor plate should work if you confirm measurements with them (the 6 pot gearbox lip diameter is 10mm smaller than the 4 pot and the bolts should be at 11 & 1)Click image for larger version.

    Some pics..... a 4y lost in a S2 engine bay, a 6 pot gearbox showing the 11 & 1 bolt positions.

    Post some picks of your beastie

    I would not touch my six pot, which is wonderful... let me share a video with you, while enjoying Mallorca Island.

    The idea is for a SIII 88, moving now with a tired 2,25 diesel.

    Thanks for the information! The pics are really helpful. By the way, that "adapter plate" does not look CNC, but casting.

    The viscous won't do its job? Shall i make it "fixed" like the Series, with no viscous at all?

    Thank you !

    The 4y motor is tiny and sits way too low for the original fan to work...... way easier to go electric
