Hey, all. nice place you have here.

First i'd like to say that I'm not a Honda guy. Sorry.

However my friend has a 2002 Civic DX and is asking me what if any thing can be done to it. I have no clue. so thats why im here. asking the experts.

all i really know is that it has the D17A1 in it and an auto tranny(cringe).

Whats the diff between the D17A1 and the D17A2 thats in the EX. Can the A1 be converted the the A2? i only ask cause i seem to remember that honda stuff is really interchangable.

any help would be nice.

The ex is a 127 hp rated vtec engine, there are few mods currently available for this engine or the non vtec in your friends car, the engine management seems to be a difficult to work with; I own a dyno facility and my wife drives an 03 ex which I dynoed while she was at home{wink,wink}, made 111whp on our 248c dynojet. Removing the air filter element got it to 114, leaving the top off of the air box lost some power, dropping the exhaust behind the cat did nothing but make noise, I tried to do a drive cycle on the dyno to allow the computer to adjust for the changes which it did, unfortunately it became rich under full power and went down to about 109 with the exhaust off and a\f removed. I believe there is no power to be had w\cat back a cold air may be worhtwhile, the timing can't be adjusted, the fuel system is returnless so afp will not work, in short this will not be an easy car to tune. The old d motors are a pleasure to work with in comparison. In defense of the d17 it has much more torque than the 16 motors probably due to the displacement increase and intake tuning. Swapping parts fron one d17 to another would require a computer swap and vtec wiring to complete for very little gain per dollar.

I got 120whp from intake and 4-1header.

The motors are indubitably not easy to work with. But as someone mentioned before they have been graced with abit more torque/hp than the previous d-series motors and I believe them to have quite a bit of potential.

Eventhough the aftermarket market has nnot fully embraced the d17 platform yet it is slowly but surely making progress. I believe that rods have been release for this application and that converting to a non-returnless fuel system is a very real possibility. Spark can be an issue however, but MSD has a product that is used on the current distributorless models of the Ford Mustang, and I believe it may be applicable to the EM2 as well.

You ran a 14.7 with an intake and header? @120 hp?

No..on a 50 shot of n2o.

How do you run nitrous on a returnless fuel system?

Same way you would run it on a non-returnless fuel system. It's a wet kit so it's providing fuel. I also have a v-afc hooked up to bump that if necessary But I haven't found the need to adjust much thus far. Perhaps when I up the shot I will bump the fuel a bit.

From what I understand, there is no need to go with a non-returnless system unless I plan on using a fuel pump and / or fuel pressure regulator. Although it has been rumored possible, I have yet to hear of someone that has accomplished this conversion.

I am considering a turbo set up, and from what I have read, most of the 7thgen civics are running these setups with a custom FMU or on stock injectors with AFC monitoring the fuel.

Throttle body on your D17 have an EACV on it or is it on the intake manifold? By the way impressive stats for a D17 SpdRcrChk. Welcome

I honestly have not looked for that. But I would assume it's on the I/M.

Oh and Thanks.

Hey sorry it took me a while to respond. I totally forgot about this and just remembered today. I checked on the EACV for you. It's actually on the throttlebody. If you're lookin str8 at it it's to the left. If you need a pic I will be more than happy to take one and send it to you. Lemme know. Email me: [email protected]
