Wanted: 2.4 or 2.8 engine

[Greg]

Hey all,

Looking for a decent engine to drop in my '72 240, while I spend time rebuilding the stock motor, that project could take a few years or so.

I'd like something reliable that doesn't need more than a tune-up, doesn't really matter to me if its a 2.4 or 2.8 engine. I thought that someone may have a 2.4 engine laying around after they converted to a 2.8, that they would let go for cheap.

Looking in the Bay Area,

Thanks, Greg

Hi Greg,

I have a complete L26/E88 that was rebuilt about 40k miles ago with to stock specs except it has hardened valve seats/guides. It was a strong runner when I took it out 6 months ago. I also have a couple complete L24/E88s but their condition is unknown. If you don't find what you need on the SF Penisula I am only a couple hours away. Send me a private message or email if interested.

Have fun!

Hey Royce, CAN'T YOU READ???? He said L24 or L28. He doesn't want your L26!!!!! JUST KIDDING!

Greg, what is "cheap"? I am a few hours South of you...if you don't find what you want, there are a few laying around here for $50 and up...Whether they require "just a tune-up" or not will have quite a bit to do with the price, of course. Most of them have been sitting for a few years.

Good Luck

Wow, the L26 still cannot get any respect!

But hey, there is nothing wrong with putting a L26 with SU's into a 240, it's an easy and cheap way to add a little HP!

if an L26 stock will bump up the ponies, would an L28 w/ dual downdraft Webers do it even more?

[Royce]

Hmm... good question. I think it goes something like this(gross HP figures)...

Stock '71-'73 L24 150 GROSS HP

Stock '74 L26 ~160 GROSS HP

Stock '75-'78 L28 ~170 GROSS HP

Stock ZXTurbo L28 ~180 GROSS HP

~ = approximately

So on one hand my answer is yes because the increase in displacement could account for more torque and power.

However, there were many things changed other than just the displacement over the years. I don't know if the Weber downdrafts would be a performance improvement or not! Anyone know how much air they flow?

Given the choice, I would go with the SU's or 280FI, if for no other reason because there are not as many people familiar with the DGV downdraft Webers and it is hard to find anyone to give you help. One more thing to think of is that when you increase displacement like from L24 to L26 or L28 you also increase the engines need for air and fuel. Although, it is not a big difference in displacement it may require a little more tuning. Most likely you can adjust the SU's to compensate, and the FI can be tweeked to some degree plus it is already set up for the engine size, but the Webers may require you to replace jets to get the most out of the engine.

Of course if you already have a car with Webers and you want to might as well try it for yourself. You can always change the intake later!

Anyone else?
