I would like to compare different engine weights,
preferably when they have their full capacity of fluids.

The front of the car will always be the heaviest,
but for driving in conditions like very soft sand, probably the lighter the better.
This has me re-thinking the idea of prefering an EJ22 to an EJ20.
Now that I'd need to swap brakes to have an EJ certified, I might prefer a rebuilt EA81 or EA82 and a Webber carby swap.

Being lighter at the front could make it easier to get unstuck as well.

I think I heard there used to be an EJ18, but it doesn't get mentioned much.
Is there a good reason it's not talked about?

How much do these weigh?

EA81
EA82
EJ18?
EJ20
EJ22
EJ25

No weights in these links

but I learned about the EJ181, EJ182 and EJ183; all of which are an improvement over an EA81 or EA82.
I like how there is more stroke and less bore on these motors.
Torque and horsepower improvements over even the EA82 MPFI.

oh wait I just did

GOOGLE it

Seriously it isn't going to make much difference what engine you choose, with the right tyre pressure and plenty of power it won't make any difference in the sand. 20-30kg is nothing. If you really want to save weight through the mrs out. Your just getting anal about it now.

Hahahaha.

Okay the different weights is not as big as I assumed.

I've seen comparisons between a Chevrolet 410 cubic inch big-block vs. the same sized small block put in the exact same Camaro.
They built both for as much naturally aspirated power on a certain budget. $2000 USD?
Anyway, the big-block made more horsepower and had a higher torque peak rpm
but the small block killed the big block at the 80 ft mark,
though the big block managed to squeak by the end of the quarter mile.
Part of this was weight transfer made easier by a lighter front end... 140 lbs lighter?

Bit of modification and your good to go, seriously lightweight engine.

Nice... does it come with the cut away to show how powerful the engine is?

Might be a bit difficult to start in winter, just ask Jonno- see this thread. This is the slightly larger engine than Jonno's though.

Chalk and cheese mate! PLUS both were built for power and were on a playing field where they could both perform well against eachother. If you seriously built an EA82 you'd probably just out do an EJ22 that's just been ripped from one car and dropped in the other.

The amount of weight you're talking about in these chev engines would probably be the equivalent of an EJ22 if not a bit more again.

The EJ conversion in the L series is a tried and tested conversion, there's really no need for these questions unless your engineer is worried about it, even then he should have easy access to that information without you having to do the running around for him.

Trust us when we say that you'll love the EJ - just read my build thread on Ruby Scoo and you'll find later in the thread that I've re-read what I wrote at the start and found that my questions were rather naive upon reflection after finishing the conversion... You just need to trust those that have said it's worth while!
