How can you tell if your hatchback is a Dx or a Si? Is there really any difference for the intake if it is a Dx and an Si? because they sell intake on Ebay for Si and they say it is different from the intake for a Dx

Electric sunroof on a SI, motor will be DPFI on a DX with a engine code of D15?? and the SI will be MPFI and will have engine code D16A6. Both intakes should fit pretty much the same you are talking about intake pipes right not intake manifolds right.....

si is power everything, dx isn't

 

Yes there would be a difference for those intakes....

 

The DX (Dual Point Fuel Injection) needs a longer intake tube because of the position of the TB.

If your hatch has DPFI, I wouldn't bother with an aftermarket intake. The throttle body is so restrictive, there won't be a noticable increase in airflow. Do an MPFI swap first, then get an Si intake.

 

Well I know had a DX and the intake pipe fit in the engine bay and bolted to the side just like the SI did. As for the SI having power everything what would that be? Only electric thing on the hatch that was a available in the US was the Sunroof

its already been said but the DX intake needs to be a bit longer. so you could either buy an Si intake and just use a longer piece of hose(the hose that connects it to the TB) to extend it to the right distance, or if you have DX intake available, u could just get one and it should bolt right up.

 

Your all forgetting one thing, the DX is a 1.5L and the SI is a 1.6L. They arent at all much faster though, my friend has a SI and I got a DX.

 

Converting a DX wiring is not that hard, I did mine in 3 hours TOTAL. the first time for me and with no help. and the DX is a lighter car than the Si. And a lot cheaper to pick up. Less likely to have been thrashed and wrecked.

the only advantage the Si has in the chassis dept is it comes with a a rear sway bar and rear disk brakes, and the rear brakes don't make a huge difference on the street. The front does most of the braking. You can pick up a DX for a song even in DC area. An Si is going to set you back some coin. for the difference you can modify the suspension to were you can eat a stock Si for dinner, once you swap in a better motor. And you don't have the extra weight of the sunroof and the extra sound deadning to haul around. which if you want to get technical he's even better off with an hf which has even less of that and just undesireable brakes and hubs to swap. I paid $350 for my DX with 108,000 on the body. try touching an Si in any kind of shape for anything near that. I'd rather take the difference of what an Si would have costed and put it towards my DX to hop it up.

 

The Si cam owns DX.

 

I've had 2 EF's and have never had a bit of trouble with the sunroof - and since I have no a/c its a nice thing to have , well its a nice thing to have anyway . Not mentioned already are the much superior seats and the clock . I really like my clock I'm trying to remember if my mom's DX had a tach - I don't think it did , I want to say it had a bigassed fuel gauge instead and the idiot lights were a little different .

 

stock to stock the Si is better

in hawaii, i haven't seen many Si's without rusted or duck taped sunroofs......

IMO i like the DX better, i dont think the sunroof helps with keeping the car stiff and the rear brakes dont make much of a difference. the swaybar helps but you can always put one on a DX.

Si dont have power anything besides the sunroof and my DX crx has a clock and a tach....

 

 

We were talking an Si vs DX as a platform for modifications. yes the Si has a bit more power stock 106 vs 92. but if you swap the engines and do any tweaking you have an Si that comes in with a several hundred pound disadvantage. Besides the Si chassis costing you a hell of a lot more to begin with. put aftermarket adjustible sway bars and a different engine and then just what advantage does the Si have. NONE. I bought a clean DX and swapped a ZC egine/trans in mine for what a high milage Si sells for in this area. And I can dust them off quite readily. Nobody doubts the Si was a nicer car as it left the assembly line. But the Si is the heaviest Civic of all the models.

 

man it sucks not having that clock

 

all of the wiring is there, just get one and plug it right in
