I got a new swap going now. My friend has taken the motor out his CRX and hes been looking around at doing a swap. He not sure about waht he can swap into it besides the b16. Wondering what is a good big motor that he can really get some major power out of.

Actually now you have just about any number of options.

 

The b16 is a semi-cheap and pretty popular because of it, and has a whole lot of aftermarket support. The people looking for a little more usually go for the b18c5 swap and then boost it, which would be more than enough power for a crx.

 

Personally, if I were to boost I would go with the jdm h22a. It has a little more tq and about the same amount of hp as the b18c5. The swap is really popular in the 90-92 accord scene with some pretty decent results.

 

If I were going to go n/a I would go with the k20a2 with the full skunk2 catalog and kpro.

 

If you'd like to know more about something specific please feel free to ask.. I've been around b16 swapped crx's and hatches in the past and around swapped hondas for a good amount of time now.

 

A lot of people will say to go K before you go B, which I would tell you the same thing except the aftermarket support for the B is great and the parts tend to be a bit cheaper.

H22 is tough to fit into a CRX though from what i hear. I was going to put a B18B into mine (i believe that's the engine code for the 95 LS non-vtec, this was some years ago) and boost that, but the car suffered spectacular and catastrophic engine failure of its built 1.6 single cam, and i ended up unloading it. I had the engine and the turbo, but nothing else really. I bought my first 280z after that and haven't looked back.

If this was a car and/or engine swap that is rare, not covered well already on the internet, etc, we would turn a blind eye and let it run its course. A Honda CRX engine swap isn’t going to be hard to find info about, As such…

By the way, a place that I've heard a lot of good things about is www.hmotorsonline.com .

 

And another thing that I would say is that if the h22 does seem to be a tough fit into the crx, I would consider a k24 with a k20a2 head. That way you would have vtakk and a low cr that's perfect for boost.

 

I know that a k24 longblock can be had for pretty cheap as long as you don't look for the one out of the acura tsx. The rsx-s 6 speed transmission bolts right up (if I'm not mistaken) to the k24 out of the honda cr-v/element too.

Actually, the k24 has several variants that go from about 160hp to 220hp. The k24a2 is the motor out of the Acura TSX and it makes about 220hp and (obviously) has a higher compression ratio so it's not really that popular among the guys looking for boost, while the k24a1 (out of the cr-v) seems to be quite a bit cheaper and handles boost a whole lot better due to the lower cr.

 

The most popular thing, as I mentioned before, is to throw in a k24a1 longblock with a k20a2 head, k20a2 tranny, then boost and tune with Hondata kpro. If you're looking for a tranny that would bolt up and has an lsd stock there's always the k20a trans or the k20z3 trans, both of which should bolt up without a problem. I personally would stay away from the k20z3 transmission because there's a design flaw in it that causes extensive 3rd gear problems.

 

As for the B series, I really don't know all that much so I can't really comment.. The extent of my honda knowledge ends at the k series, :D.

 

For the record, I think that a built/tuned k20a2 would be awesome in a crx. Think about it, you'd end up somewhere around 300whp and have a 9k rpm redline in a 2000lb car. It's like a go-cart that sounds like a pissed off weedeater.
