I'm considering the 2.5 4 cyl and 3.0 6 as possible kit car donor engines. I particularly like the low cg, and the room to work/add accessories. I used to autocross a friends WRX around and quite enjoyed it. Can anyone tell me how much these engines weigh? Will the 6 cylinder mate up to the 4 cyl gearbox? Any particulars of these two engines that I should know about? I've not mentioned the WRX engine because it's more expensive, and I want something with a broader powerband.

Thanks for any and all input

If you're interested: Here's my current kit car:

The 6 cyl motor can bolt up to the gearboxes designed for 4cyl. I don't know how many custom brackets and mounts you'll need to make, but hey, you're building a kit car

I assume it shouldn't be any worse then mounting any tranny in a kit car.

 

woah, how much does one of those kits cost.
cool

 

So that weight is with alternator and manifolds? Not bad!

Thanks.

Any more?

 

I don't know the exact weights, but I can give you rough order of lightest->heaviest. Starting with EJ25, then EJ22, then EJ18 (basing this on near-identical blocks, except the larger engines have more bored out of the cylinder walls, and similar SOHC head designs except for Phase I EJ25s) then EJ20s, then the 6 cylinder engines. The EZ30 was significantly heavier than the EJ25 despite having near identical outer dimensions.

 

EJ22 long block, no accessories or intake manifold- 188 lbs.

I found this one I'll see if I can get the rest

 

You're really peaking my interest. So the EJ 25 is lighter than the 22, which isn't bad at all. That's very encouraging. It really makes me wonder why I don't see more of these in kit car applications. A low CG, light weight and torquey motor seems just the ticket for a 1200 lb. car.

 

I'm just guessing on the EJ25,22, and 18 non turbo motors. They are all going to be very similar in weight.
