In short, yes. It will fit. They're "universal" fit to the OE exhaust.

You can probably find a cheaper one, or one that comes in a package deal with something else, though. Look a bit more on eBay, they're around.

?wtf.

You need to contact the seller and ask these questions.

But i wanna know did anyone ever installed a Preformance header on their Civic VXs, i need to know what brand is a direct bolt to the oem piping on without the welding etc.....
some brands say i need to cut and weld.

GOod luck man should sound pretty nice on there

Well, there is the issue that the VX's exhaust manifold is a short log-type, with a catalytic converter right there.

In order to retain a catalytic converter, you'll have to get one from another 5th gen model and fit it to your exhaust, then that header will fit.

The thing I don't remember is whether or not your downpipe is long enough to make up the distance between the catalytic converter and the rear pipe section. You'd have to look into that yourself.

just get a cat welded on further back in the exhaust

The cat bolts onto the header. It either bolts on in front of the engine, or it bolts on under the shifter assembly attached to the downpipe. In the case of the header that is displayed, it bolts on to the downpipe under the car.

The main problem is your engine runs slow enough most of the time that a header like that is to big, it's like a little kid trying to play a tuba (really, exhaust systems fallow the same rules as wind insterments, not the rules of constant flow and restrictions) this engine also has lean burn and runs rather cool so it needs the catolitic converter close to the head to keep it hot enough to keep it from clogging and needing to be replaced.

+1 to Ryland's comment on the cat being very close to the exhaust valve to keep temps higher in the converter. Both my VX and Insight are that way.

With that header, with large diameter pipes and a converter a foot further away from the exhaust valve you could have problems trying to keep the revs low and stay in lean burn.

..."Tri-Y" headers are good for low-end, especially small displacement engines having low-torque.

...for that very reason, they (usually) make excellent "street" headers.

...anybody remember the "Auto Shop Series" article, "Header Science," in the November '73 issue of HOT ROD MAGAZINE, pages 114, 115 and 118?

Which is completely inapplicable for anything except the "standard" types of engines.

Lean Burn is a slightly different beast, however, the converters were placed in front of the engine on more than just the lean burn Civics. The setup can also be found on CRX HF, Civic STD hatchback (with D15B1 engine, not B2) and CX/VX models, possibly others, those are only the D-series variants.

The STD hatchback model was equipped with a D15B1 engine, which was exactly the same as the D15B2, but with a mild(er) cam. In fact, you can get 20 HP just by swapping the cam and using the OE ECU for either engine, if you had that one.

Regardless, I don't think the VX will like the cat being further away specifically for the lean burn issue and keeping the cat warm. You'll be a gross polluter even when fully warmed up because of your NOx emissions, which won't be converted properly.

That notwithstanding, the information is there, and readily available to make the header fit your car.

Still have to check into it yourself.

I'm going to recommend at this point that you don't screw up the VX, sell it and buy a ricer-raped model, so that someone who gets the VX might actually use it properly.

No offense, but you're really going to end up with a POS if you keep on this path.

The VX is kind of an uncommon engine in that it has high torque at low RPM and that a header that increases torque in other 1.5 liter engines are most likely going to do very little for this engine, my vx has plenty of torque at 1,000 to 1,200RPM that is just above idle, for most engines of this size low end torque is thought to be in the 2,000 to 2,500 rpm range and with the vx engine the V-tec kicks in at 2,500 rpm and unless I have a few passengers in the car and want to merge on to a busy freeway my engine never revs as high as 2,500rpm.

A header on a VX is like plastic surgery on my 99 year old aunt.

In my Insight the 'exhaust manifold" is part of the head casting to help the engine warm up faster. Pretty sure they did the same thing with the latest version of the Prius.

Nothing new there, Ford did it with the old in line sixes a long time ago, although maybe not for the same reasons.

Actually, the Z1 is a very tunable motor. It's the ECU that's the limiting factor.

In fact, the Z1 can handle over 300 HP at the crank without grenading, like any other D-series, except it's rods aren't as weak as other D15's. It has 1.6 rods.

.

Wrong forum, buddy.

The Z1's build package is that of necessary components for most D-series performance builds. It's already a Vtec motor, twice over.

Before you even think about swapping engines, do a little research into what you actually have right now.

I still must insist that you don't rice the car, though. Sell it for a few thousand before you tear it up, then buy yourself a chassis that's already been swapped to whatever you want. It's cheaper/easier that way, and someone else will get a perfectly functional VX to use.

These engines only wear out after 300,000+ miles, or from abuse, so there is very little demand for them used except for people who want to put them in other cars, people who are putting alot of work in to building... basically the exact car that you have in stock form.
Why not find a civic CX? it's the same car but with the base engine instead of the V-tec and has steel rims, if you find a 1992 it will even have the v-tec wiring (all 1992 civic hatchbacks had the same wiring harness), you have a car who's engine will last forever, gets over 50mpg... and you want to do what??? look on craigslist and sell what you have to someone on here.
The car that you have is special because of it's ECU, it's head, intake exhaust and o2 sensor, it's sought after enough that people seek them out, travel great distances.

close thread..

The whole engine is different, actually, from any other Honda engine.

The top end is built from a Y8 cast core, and has enhancements beyond that, but does also have quench pads.

The bottom end is a standard D15 block from the EG series of Civics, but the crank, rods, and pistons are all different. The Z1 is the only Honda D-series engine that got a 1.5L crank with 1.6L rods and pistons (The pistons don't really make a difference between engine sizes, the stroke and bearing sizes are all that changed).

This means that the VX's rods and pistons will swap into a 1.6, but not into any other 1.5, while the crank will swap into a 1.5, but no other 1.6, and still require 1.6 rods.

The crank mains are 1.5L sized, the rod journals are 1.6L sized. It still has the shorter stroke and deck height of the 1.5L though.

One thing I had considered doing with a 1.5L block was to have it align bored to fit the 1.6L mains, except having it milled offset from the OE crank centerline, to better take advantage of piston force at TDC (The piston at TDC would be a few degrees past TDC measured at the rod journal.)

The Z1's combo crank was (indirectly) the inspiration for this.

Christ,

That was worth the price of admission right there. Lucky me! Honda's are great cars. I was reading another article about you are what you drive. One factoid about Honda drivers 70% of them have a college education.

To the VX Kid, don't ruin a scarce commodity. Drive it the way it is or sell to someone that appreciates it for what it is. Don't be stupid!:eek: Be the most thrifty young adult on the block, afterall, you are cool enough to be lurking around on ecomodder.

Keep it stock,
Dave

I sold my 95 Civic 2 door EX to a young kid, he had the attitude that you can't ruin a Honda. He blew it up 6 months later. :mad:Oh well, he traded me a 93 Miata for it. 71,000 miles. My Civic had 185,000.

I want your Miata. :P
