How big is yours?
I know this question gets asked all the time by us newbies (and some oldbies), and that there are some references about with bits of the answer,
but...
how big and heavy are the most popular engines and gearboxes?
Has any one measured a variety of engines, with the same tape measure, for the same dimensions, or weighed them on the same scale in the same state of
assembly?
I think most of us want to be able to work out how much room to allow in the engine bay and trans tunnel before we start cutting steel... 
The most asked about engines seem to be :-
Ford x-flow
Ford Pinto
Vauxhall XE (Holden/Opel/Daewoo?)
Toyota 4AGE
Mazda B6 (MX5)
Rover V8
and gearboxes :-
Ford Escort (for book builders)
Ford Sierra
Toyota T50 & W5x
Mazda MX5
Vauxhall/Opel
Rover SD1
The most queried dimensions seem to be :-
overall length (front of pulley to rear of block)
overall height (top of rocker/cam cover to bottom of sump)
motor height (top of rocker/cam cover to bottom of block)
highest height (from highest bit e.g. plenum to lowest bit e.g. sump plug)
width of engine (excluding manifolds)
overall width of engine (including manifolds, filters)
and for gearboxes :-
bellhousing length
bellhousing width
bellhousing height
gearbox casing length
gearbox casing width
gearbox casing height
distance front gearbox to shift lever
I'm sure lots of you have been through all this - someone must have written it all down on the back of a ciggy packet somewhere
... or is this already in the files area and I'm just too blind to see it?

Certainly Sierra (T9) gearbox dimensions have been posted recently. And I've definately seen the odd plan of Pintos around. I'll see what
I have in my file of old fag packets!

James,
I didn't think you smoked?
There certainly have been dimensions given for heights of engines, by david walker iirc. this helps you know what you can fit easilyish under the
bonet!

This seems to come up quite often, so next week we are going to do a "scientific" experiment.
My College tutors dad runs a scrap yard, and we are going to pull some engines out of cars and weigh them in the same state, that is with all lines
and cables cut at mid points, all ancillarys attached, no fluids.
So far we've go a pinto, a crossflow(actually a more modern HCS, but basically the same engine) a Rover V8, A vauxhall 8 valve and a toyota
4age.
Definative answers next tuesday!!!!
Cheers
Chris

I haven't seen it but I presume it's in the back of an MR2.

I can help with the Rover SD1 LT77 gearbox. I weighed it myself whilst standing on bathroom scales and it was 47Kg's. I think it has oil in it
and this was complete with bellhousing and gearlever.
I'll be very interested in the weight of the Rover V8 engine as this has been the topic of much debate in the past. I suggest you remove the
cast steel manifolds on the Rover and other cars as there is a lot of weight in them (especially the RV8 ones) and most folk will probably use custom
tubular manifolds anyway.
Cheers,
Craig.

I'd weigh my engine and gearbox, but my mother in law broke my scale last week.

Toyota 4age with ancils and gearbox weigh in at 150kg. I believe bare block and head are around 85kg's and the t50 weighs 29kg's.
ive attached some pics of the t50 with dims.

Any chance your "scientific" experiment could include digital photos of each engine (front and side) in front of a marked grid (say a
white board with black lines at 1cm spacing?)
Then some enterprising soul could "process" these through a CAD package to produce scaled silhouettes for comparative purposes.
I've seen someone do this on the net for a Midget engine/trans swap.
I'd offer but my PC is state of the Ark

Right Then
first of all appologies to Bryan, I didn't see your post, so no piccys
The Engines were taken out of the car without gearbox or starter motor, all control cables cut at mid point and fluids drained, to compare like with
like the exhaust manifolds were left on, disconected at the first joint.
The weights were taken on a digital weighbridge and rounded down to the nearest Kilogramme
Engine type is followed by the actual car the engine came out of.
Pinto (sierra 2.0 inj)...................135 kilos (295 Lbs)
Crossflow (Escort HCS1.6 carb)............109 kilo's(239Lbs)
Rover v8(Range rover inj)...........160 Kilo's(324 Lbs)
Toyota 4Age (MR2 inj)...............103kilo's(225 Lbs)
rover K series (216 inj)..............100Kilo's(220 Lbs)
Ford Zetec(escort inj)..................105 Kilo's(231 Lbs)
With thanks to Jack and his big crane!

Chris,
Interesting figures, well done for this valuable piece of work!
I'm not trying to argue with what has clearly been an objective experiment but I am surprised at the weight of the Pinto as most folk have
"accepted" for some time that it is slightly heavier than the Rover V8. I think the figures for the V8 are what I would expect, in fact I
guessed 175Kg's which would account for the starter motor and fluids.
Again I'm not disagreeing with the fact you have left the exhaust manifolds attached but clearly on a V8 this will work against it as there are
two of them and let's face it they are not the most dainty of manifolds are they?? Fitting a tubular manifold to both the Pinto and Rover would
bring them pretty close.
Anyway, as I said, an interesting and useful piece of work so thanks for taking the time!
Craig.
ps. Just weighed the manifolds and they are 16Kg's for the pair. Now what else can I find that we don't need...

By any change, somebody has the figures from a Dohc 2.0 or Dohc 2.0 16 v ( Rs 2000 90-93 )
And from a MT 75 compared to a T 9
Thanks

Nice one Chris!
Good to have it definitive! You gonna put this up on your site? It'll get lost here if you don't!
Cheers,
James
