Ok, heres what im thinking. For cost reasons, I would like to install a K24 from an accord ($750) in my Si then down the road swapping the K20a2 head onto it (piece it together). Im wondering if K20EG's wiring harness will work for this? Also header? What do you guys think?

There are approximately 400,000 cars in the US with K24s in them. This will be the swap that will make the K swaps mainstream. There will be well over a million K powered cars from Honda on the road within the next two years. Their sheer numbers will insure that the engine will remain reasonable in cost. I predict that in the next 6 months or so, someone will come out with K24 cams that will allow the engine to make 200hp without doing a head swap.

It's also a better engine for boost. They come with a very strong crank and lower compression than the K20s. But the big reason is the 2.4 liters of displacement. I would venture to say that with the correct aftermarket designed cams and a JR supercharger with K-pro you could get 300 hp from an otherwise stock K24A1. And it would have 200 ft/lbs of torque too.

Basically, will a harness that has been modified to work with a k20a type-r in a EG, work for such a setup?

The K24 harness on the Accord engine disconnects at the firewall, so that one won't work. I haven't had a chance to check the one from the CRV or Element yet. The pictures from the parts catalog are inconclusive. I have one coming on a CRV engine, but I don't know when it will be here.

Until I or someone else figures it out, you will need a Civic Si or RSX engine harness. That harness will need to be modified slightly to fit the K24. You will also need a modified battery harness to reach the fuse box and battery. Then you can use the Hasport conversion harness to make the rest of the connections.

Why use the 5 spd, I would go with the 6 for the lower(numerically) final. With the extra torque available in the k24, a 4.7 final is not necessary.

Hey Brian. If I use a CRV engine with 5/6 speed transmission. Would I get a ECU from an RSX or a CRV? If I get an RSX ECU and send it to hondata for Kpro upgrade, can I use it for a K24? Are the base maps available?

If you're doing a K-pro;
CRV, RSX, or Si ECU for 5 speeds
Type S/R ECU for 6 speeds

Any will actually work for 5 or 6 speed, but only the RSX Type S/R controls the reverse lock out which 6 speed users will want.

So the k24 will fit into an eg without any hood issues.Which k24 will be the best to get accord,crv,element.Could you pass smog in california with this swap.

You have to remove hood under-structure for clearance. The CRV which is a light truck probably won't pass smog transplanted into a passenger car. Talk to your local ref and see what he is going to be looking for to allow you to pass emissions. It may require a bunch of stuff that doesn't come on the EG.
