Crikey that's a bit rich! Especially when it has standard running gear and torn up interior.

Any idea how the tailgate would open?

The lights would need to be cantilevered over the rear 1/4.

Although I will say the front looks good but the rear lights seem a bit of a mismatch.

Red underside but white engine bay?

And no, I don't get how the rear is meant to work. Maybe the tailgate doesn't open?

That seems a bit pricey. Is this what they usually go for?

MB are worth alot in Japan these days they are a cult status car
the way they are going Ive seen them more exxy than 86 cars for sale
in some cases and more than the 67 corona 1600 GT4 coupe
and a datsun 140y excellent SSS sedan I missed out on thanks
to procrastinating thinking they would be around for my indecisions.

Anyone know if I can fit the internals of an F8 engine into and F6B?
Id like to stroke an F6 and get the engine ready for when I find a MBoy
as I know of an old Jap guy here, (I live in and out of Japan lately)
well he will let it go for cheap, has rust but nothing I cant handle.
Yet love a turbo 800cc and rwd setup using modded awd gearbox.

I drive a suzuki carry truck these days was 4wd non turbo but
converted to rwd only recently as I only use it on good roads
and its flies being 120kg lighter and low diff ratio.
Next engine is turbo K6 series but love to put in an M16a in her.

Not possible, or advisable with how thin the F8B rods are. Monster Sport make a 720cc stroker kit for the F6A though.

Thank you Brayden,
What if I use custom rods and pistons can the 65mm bores handle overbores?

Buy a K6A and get the forged parts directly from SuzukiSport/Monster Sport. Would be easier and cheaper than any other option.

Im really interested in the F series so I dont have to engineer the MBoy with new engine
If I went with a K series, Id get the K10B 998cc 3 cylinder re-stamped that, then boost it
My carry truck will get the K10B 998cc engine after the current one kicks the bucket but
will need a lower diff ratio, LSD and wider rubber all round.

The F has bigger bores but wondering if the F6x can handle overbores or better to sleeve?
I would sleeve and grout the block, but now just wondering if its just easier to do up an F8C
from china or similar.

It all depends on what you're trying to achieve and how much you want to spend. Without knowing that I'd just be guessing at advice.
Whatever the case, adding a snail automatically means a trip to the engineer because it'll push beyond 15% power increase.

Trying to get capacity more than anything else
conrods and pistons i have access to my own manufacturers
now the question I really need is can the F6 be overbored
to match the F8 if not then I will go ahead and fit a K10B
that way I can get the capacity I want and have an all alloy
engine I suppose but will need engineering :( even here in Japan
I was trying to see if I can get a sneaky 800cc F6x but as stated
maybe its not worth the effort.

F6A can be bored and stroked to 720 but I haven't seen bigger.
I've tried an F6A/F8B hybrid and although the head bolts on, the bores don't line up with the combustion chambers. (F6A bores are clustered closer to the centre.) I should do an explainer video.

Thats very interesting, I wonder how they would go with o-ringed sleeves and block grouted to the welsch plugs?
