I just recently bought a car, a 94 civic ex abs coupe, 5spd. It is completely stock except for one thing: the previous owner had ruined the D16Z6 (ran low on oil, threw a rod and ruined the valvetrain), so the shop he took it to put in a 'new' motor, as well as rebuilt the Y24/S20 tranny with all new bearings etc. I bought the car from the shop owner; apparently, the owner could/didn't pay for new motor, so he signed titile over to shop owner then i bought car.

It is a JDM D15B vtec running on the P28 ecu, passed smog no probs (though I do have to scan the paper to ask a question about 599 on the Nox?. I'll do that later). There's nothing I can do about changing back to the 'stock' D16Z6 untill I get some more cash.

What class would I be in? The D15B is a 'smaller' motor than the D16Z6; would that affect anything?

And perhaps this is a bit offtopic, but did not the EG ex coupe abs come with a rear sway bar? I have the lower control arms with the mount holes and provisions on the rear subframe, but it appears there was never a rear sway bar on the car. I know the sedans did; my bro's sedan has a rear sway.

Thanks for any input.

 

Street mod - all motor swaps go there (whether the car is slower with it or not)

 

I dont know all the engine codes as well as i could, but if its not the engine that came in it, you are looking at Street Modified, or possibly Street Prepared, but for street prepared you must have a driveline swap (engine+tranny) and the car must be in the same line of the rule book. You would have to give me the year of the two cars in question for me to find that out in the SCCA book.

If you're not terribly competitive, you could probably hide out in stock.

Sounds like you're in street modified, if anyone protested you. Unless you were winning, I don't think they would.

Does JDM count? I didn't think any "JDM" cars were really classed.

Darn, i was afraid of that. I assume i'm going to have some pretty good competition. Do you think I should keep on the lookout for a D16Z6 or should I just spend time/money and work on what I already have? I'm more of the person that lets the motor be, and work on suspension and seat time.

 

I kinda push the "JDM" thing out when i first look at stuff... Lots of people like to say "JDM" when it comes to a package even though the engines come from different USDM versions..

If it is really an engine that wasn't available in the US, then it would go to D-Modified. (or E-Modified if its over 2 liters/rotary/forced induction) Yes you might find yourself against a Rotary Honda in E-Modified.

Transmission is the original Y24/S20 transmission. The D15B motor is 94 or newer, because the 94 or newer D15B came with the non-painted valve covers. Earlier versions of the D15B came with the 'poweder coated-like' black cover. http://asia.vtec.net/article/d15b/ My chassis is a 94.

 

As far as I know, racerjon1, the D15B only was availible in Japan. http://asia.vtec.net/article/d15b/ Its .1L smaller than the D16Z6, but, supposedly can rev to 8k with a P08 ecu (I've only read this while researching the motor before I bought the car, I dont know the validity of this), and has a more agressive cam than that of the D16Z6. Power is about the same if not slightly [perhaps 1hp] more than the D16Z6.

If you're racing locally, I'd look for a D16Z6 valve cover and play dumb.

It's stock, right? I think so.

Cool, I stand corrected, the class is too expensive for me to tackle.

The D15B looks exactly the same as the D16Z6 except for the engine stamping code on the block. Valve covers are the same. The original D16Z6 intake manifold and exhaust manifold was used so it could pass emissions visuals.

The only 'mod' i've done so far was to remove the air intake resonator box. And really, this is only a 'cosmetic/sound' mod; unless I fab up some dryer duct to direct some cooler air in from the front.

I plan to go with Hawk HPS all around, and autozone blanks, either the duralast or valuecraft; i'm not sure what people on here are having luck with. Then get some better tires, and i'm going to start auto-xing.

Don't forget to put your air intake resonator box back on before you go. It's easily protestable and you'd lose.

 

Since no one answered the sway bar question, I'll tackle it. The only EG (not including del sols) with a factory rear sway bar was the EX 4 door, it is a 14mm just like the integras. So no, your car did not come with one from the factory.
