If it's a Si, then any d-series or zc is pretty much a straightforward swap.

Another very common swap is using the stock block with a z6 or y8 vtec head. Or just doing a complete d16z6 swap. Doing the z6/y8 will get you about 20 hp at the crank over a stock Si. If you have a dx crx you're going to have to convert to mpfi for any of the mentioned swaps, or any b or h series swap for that matter.

As has been said, any other swap is going to require new mounts, shift linkages, axles, and wiring. And if it's a hf, you're also going to have to replace the front hubs, lca, etc. www.d-series.org would be another site I haven't seen mentioned yet with lots of good info.

For the best swap though? My money would be on a k20 or k24.

 

well when i help my friend put an A1 in his 94 civic, it didnt run right cuz of the intake manny. wee had to put a B1 intake manny on for it to run right.

 

b18a1....build it. boost it.


love it.

 

ZC is probably the cheapest and easiest.

 

Yuck. I don't know why people waste their money on ZC swap's for real. It's nothing really. He's trying to have a track car as well, and to have a track car, you have to have money. Yes, A ZC may be cheap, but D-series aren't such a great platform to start with as a B-series is. Instead of spending almost 8 grand for a k20 swap. You could have a Nasty B-series swap boosting and it be built! It's really all in "favor" to most people.

 

budget16 is the cheapest

 

I'd say so. Full swap for 1500 or less. 160Hp stock! Pretty much a direct drop in as well when you get the mounts that come with the swap, no cutting or anything needed. Just wire it up, drop it in. Bam, your done.

 

go b20vtec.com thats a good site if you are gonna lsvtec or crvtec

 

I was thinking of going with CRvtec as well, but I heard the B20s cylinder walls are really thin?
