Project ED.... Engine inquiries

[Webby_roller]

Hey guys, It is closing towards Uni holidays and that means I finally have some money and lots of spare time...

I have my little ED6 and love the little hatch, and as such I am going to attempt a project car.

For project ED, I am currently researching motors... As I can kinda guess what most people will say, and what I have researched I am more after what people have done, how they did it and issues, pros, cons etc.

The choices I have for motor:

1. B18c: More expensive, easier fit, less power, better fuel efficiency...

2. H22a: Cheaper, harder fit, more power, fuel efficiency questionable...

I will be purchasing another ED6 and a half cut to complete this (if it gets started at all)

I like the b18 cause of the slightly easier installation, but I like the idea of a H22a ED, would be nice and quick, and what I have researched, the slight excess weight can be neutralized by correct spring rate and settings, but will mostly focus on 1/4 mile car.

Any input would be greatly appreciated.

Cheers

for 1/4 go h22

dont be put off by weight

there is a h22a ED in NZ that is used as a circuit car, so there is no prob with weight

[Webby_roller]

Cool, I have read as much as possible so when I have the funds I can go for it, The weight differences between the B and the H isn't as much as most ppl think. I can't remember the site, but if I come past it again i will reference it, the difference is something in the range of 20 kgs on the B.... Don't quote me, but if i find the site it came from I will definitely reference it....

[trism]

yeah, i found it was well, i was doing research on same thing

its barely anything

and if you do a H2B its even less

[Webby_roller]

Yeh... I am going got buy the full half cut so I should have everything i need.... What did you find during your research? And did you every plan to do it or just seeing what was out there?

I have found some of the issues with putting the H22 in the ED with the H22 gearbox... I haven't done much looking into a H2B yet. May see what I can find after my exam tomorrow.

I will try keep this thread up to date with what is happening with Project ED...

Completed some more research today about a H2b conversion. From what I have read it is a good swap for people that have the b series box already.

I only have the D-series box and as such am just going to get the half cut and run h22 motor and box. One downside of the H2b is that the bonnet has to be raised approx, from some sites I've read from, 3 inches max. Which is ALOT...

I have read a couple of posts of people complaining about the differences in the H2b setup motor and gearbox combination. What they were saying is that the B-series box is used to being used to rev to 8000-9000 rpm, where the older h22's just cant rev that high and they end up spinning bearings... I guess that could be just cause of the age of the motor but im just writing what I have found in case anybody goes searching for information about such a swap in the future.

The search for a half cut has begun, and it is harder then expected.... But I will see how it pans out in the next couple of weeks to see if it is still a viable option....

[trism]

the box isnt going to make the engine rev higher

[cristian]

longer ratio gb will get higher speeds for lower revs...but then again, u'll get there slower..

[Webby_roller]

Yeah I know about the box issues.... Its not viable for me anyway as I don't want to have to pay for a halfcut and then a b series box... I was just writing about the info I found.... Spinning bearings could be caused by misshifts.... But i couldn't find anything else about the spinning bearings so I guessed it wasnt that big of a problem....

[Webby_roller]

Found my half cut... Just need to get the last of the funds after exams to pick it up... Before I actually purchase it... Has anybody done this conversion on OZhonda??? If so I am quite worried about engine mounts and would love to hear how you did it... I can get some from overseas.. But will come in at a staggering US$750.... Would getting custom mounts made be cheaper??? And would custom mounts be harder to get though a engineers certificate???

Also, i know people have heard of H2B... It seems that bisimoto also make a H2D... hahahaha, i highly wonder if the d-series box could take the increase in power from the H motor???

[trism]

may as well jsut buy engine mounts. getting cutoms ones fab'd up would cost about the same

[SlobberGoat]

Do the B18C swap first. Then when your happy with that, buy another ED6 and do the H22A swap later on.

Don't go crazy first off, as chances are you'll throw the towel in before completion.

[Webby_roller]

Is the B18c really that much easier to install compared to installing the H22???

[Paul1985]

You are right.
That's my opinion.

Fair enough, the h22a may sound cheaper looking at the halfcut price. But by the time you get mounts and the other bits and pieces required to make the h22a work, the prices will be similar.

Dont forget an EFi conversion.
Best bet is to try find a CRX EFi tank/pump/lines...

Will also be alot of wiring to work out more than likely.

[Paul1985]

BTW. Fuel economy... honda's are fairly fuel efficient, even if swapping in a 1.8 or 2.2 litre... Not something i'd be considering when upgrading to such an engine.

[Webby_roller]

^^^ for your build what sort of engine mounts did you use??? I have an idea for the fuel system that I will be setting up if I cant find an EFI tank... The wiring doesn't scare me as much as it should cause with my car atm i have had the loom apart so many times that it is quite easy to work out once you sit and think about it and have a plan put into place when working with the wiring on the car....

[Paul1985]

I have an EG with K24A in it. The mounts I am using are Hasport mounts. If you go H22A you will need some similar mounts. If you go B18C you will not need mounts, i think you can use OEM mounts, you may want to ask someone who knows for sure.

If you need hasport mounts, try JDMYard in the Traders forum on this site. They usually have hasport mounts in stock.

[Webby_roller]

Cheers... Gave them a try and will have to wait till after exams to get my goodies :)

[WTNESS]

like said in the posts above, get all you need for it to convert to efi, plus id go for a b18c for the civic ed/ef, much easier installation.

and go for circuit racing, much more fun and u get to use alot of the power of the VTAK!!

[WTNESS]

If you go B18C you will not need mounts, i think you can use OEM mounts, you may want to ask someone who knows for sure.

yeah u still have to change mounts. and bang out abit of the front right hand side so the pulley can fit.

Cool, cheers... I cant wait to get this started....
