What's the largest capacity engine that you have ever known to be swaped into a legal, road driveable car.

Any make & any model
Restricted/ Club rego is OK
Must be verifiable. No, " my mate said" etc. A picture would be good.

mazda 13b into mazda 1000 ute, normal rego, mod plated. now has 275hp @ wheels ran a 10.70.

Horsepower doesn't count, it's actual engine displacement that i'm interested in. What was the rated engine displacement of the 13b?
We could include Hadfields Merlin in a '55 Chev here as it fits the criteria.

there is a thread a bit back that may help you dodgeman it has a link to the rta website that states that:
the tare weight x 2.5 gives maximum cc's for turbo'ed motors
and tare weight x 3 gives maximum cc's for n/a motors hope this helps and maybe do a search on the rta website?
cheers kurt

13b is rated at 2.6L

Well, here's the deal. Hadfields Chev used a 1,649 cubic inch Merlin [27 litre] & was built like a tank inside to support the weight. It had seating for two people & looked, well, odd.

While out driving in my thrifty Datsun 1200 the other day, I came across a car that really impressed.
It was built a little over 25 years ago using the remains of a French made 1908 MaB car & an engine that the owner found in Philidelphia. It is a 1918 Liberty V12 aircraft engine & it too displaces 1,649 cubic inches [27 litres] & it uses a 5" bore [127mm] & a 7" stroke [178mm]
If I was to install one of these in a 1200 ute, I would probably need to drive it from the tailgate.

He has driven it from Darwin to the ACT at the time of the Bi Centanary [1988] It's on club registration & can still be seen from time to time on the streets of the village where it lives when out for a road test after repairs or servicing.
It has been to New Zealand for a little drive around there too.
The original engine was a four cylinder of about four litre capacity & it still uses the original chassis, axles, gearbox & diff.

It might be old, but it's a much cleaner instalation than the massive job that went into the Chev/ Merlin car & has a lot more road miles on it to boot. Performance is awesome with a claimed torque output of 1,000 lbs/ft & the engine is at max revs when the tach hits a little over 2,000 rpm. That's good enough for about 100 mph [160kph]
Fuel consumption in economy-cruise mode is about 9 MPG [31.3 L/100k]

With consumption like that, I looked at my 1200 coupe & found a new respect for it's legendary economy, then got in & motored home secure in the knowledge that Datsuns need only a small engine to provide all the performance I need.


Does anyone know of any bigger transplants than these.

ok so the 13b is not even in the ball park.

the only one i can think of was that chev (i think) that was in street machines with a mustang plane engine in it, car was sorta dressed up like a mustang with guns and stuff on it

memory is a bit sketch but it was something like that, dont have engine size or anything though

EDIT: is that the chev you are talking about, as i remember it was also built like a tank

That's the one. It wasn't a 'Mustang' engine from what I've been told, but it was another version of the Merlin that Mustangs didn't use. [subject to confirmation] All Merlins were 27 litre.
This one is actually roadable & is in country NSW. I was checking it out last Saturday.

Anything bigger?

Go figure! whinge whinge whinge about peter posting non datsun related pics, but you now post a thread of some stupid topic in the Main Forum and it has nothing to do with Datsun 1200's. Go Figure.

Pedro please delete this thread and Ban this member for complete ignorance.
