ED Hatch + H22A

[Terrible One]

I've done alot of searching around here to no avail about an ED H22A swap that I'd really like to start soon. I've got a stock D15 carby ED hatch and have the money for a H22A halfcut but there's a few questions I need cleared up. I've tried google aswell but it didnt give me much good info.

Before everyone says "But a D/B/K series motor in instead" I've got my reasons why I want a H series. First and foremost the 140kw+ power out of the box is what I like. Secondly the lower price which will leave more for future mods (I/H/E, headwork, cams etc). Third reason...to be different. I'm interested in straight line speed.

Is there a combination of factory mounts that will sit the motor in the car or will I need a Hasport kit?

What CV shafts will I need? I read somewhere something of DA9 intermediate shafts and EF SiR outer halfs, is this right?

I'll have more questions later. Any help would be fantastic.

pretty sure you will have to do fuel tank work as ur converting the car from carby to injected

That was going to be my next question. Is a CRX tank the same as a ED Civic or even similar?

It's not that huge a problem, I setup a big EFI system on my other car using two external pumps and a surge tank but I'd rather keep this one a factory style in tank pump. Will the sender and pump unit go into a stock ED tank?

Good choice dude. H22a FTW. We are in the process of building our one. We'll let ya know how it goes.

Be ready to cut into cross-members and structural parts of the engine bay to fit a H22A. I know of 3 broken chassis from this style of transplant. You need a SiR Civic tank for this conversion, or a USDM one or a custom job.

It's a stupid conversion in an ED due to engine bay space - it's just doable in a EG because of a bit more room. K series and B18s are a much smarter option... not that you'll listen ;) BTW - from all accounts this is the worst swap you can do - you'll destroy the handling of the ED (weight distribution, not overall weight). It's been done before in the US and in Aust and the owners were quick to sell the car off afterwards and go with K or B series motors.

Did I mention you are nuts? Get rid of the ED and get an EK if you want to do this swap.

I was afraid I'd hear something like this. I've seen people talk second hand about bad experiences but I didn't know if I should believe it. It was just the basic power to weight that had me sold on this swap. EG's and EK's are too common, I love the shape of ED's. I could have bought an EG/EK but I've always loved ED's.

K series are way too expensive. Sure they're a great motor but I'm not willing to spend $10k on a swap. May aswell buy a late model B series Civic for that money.

I was originally planning on B series but it's just too common of a swap. It would take a little bit of work with a B18 VTIR motor to make the same sort of power.

I've read on a couple different places that if the motor is positined correctly that there wont be any subframe/firewall mods needed. Apparently the alternator needs to be moved to clear the chassis rail which is no big deal.

And I'm guessing a SiR fuel tank is going to be as rare as hens teeth. Which takes me back to the problem of not wanting a big fuel system in the hatch area. I've just mounted a Holley red, surge tank and Bosch 044 in my Torana and it's a very noisy but necessary for what I've done with the car.

I'll keep doing some research. Thanks for your input Setanta.

I'm in a similar boat with my EH. Bottom line is I'm going to get a custom tank made with surge and pump (maybe) mounted inside it (plus another 20 liters if possible - 40 isn't enough for a 202, let alone a RB30ET ;) ). I've heard the stories of locating the motor - but all are about a EG, not the EDs. TBH, the D16 SOHC VTEC is the absolute duck's nuts when it comes to swaps. It bolts straight in, is affordable, mounts to your existing gearbox and when turbo'd properly, totally owns a NA B18C or H22A. It's been a popular swap in the US - never took off here though. Did I mention that you can keep all your ancilleries with this setup? I'd be doing this if I had the garage space - it's relatively unique, is only 30ps down on the SiR NA (but in a lighter body - SiRs crack the ton at 1030 kilos) and has been proven turbo-tuned to crack 200bhp on non-detrimental boost. The D18s are cheap as chips compared to other motors - giving you more money for turboing etc. The US has off the shelf manifolds etc.

BTW - either Hasport or Place do the H22A mounts - but you wont get much change from 600bucks - more if prices have gone up.

agree there mate... if i still had my ED i would have gone the d16 sohc vtec swap... may not be as unique... but with a turbo kit ull certainly get some looks. good luck with it mate :)

I considered a turbo D or B before but I didn't want a second (at the time third) turbocharged car. Already had a Nissan Stagea and my turbo 202 (LJ).

Seems like I'll have to reconsider my options then. Poor mans Type R anyone? =)
