Need help on Engine infomation+Tuning

[civiclsi15]

Hi,

i was wondering if my engine is a stage 3 vtec not just vtec-e because i have a Civic 1.5LSi Vtec and its a HB EK3 and the engine code is D15Z6, i know it has an economic mode when i drive in third/fourth/fith below 2.5k but above that it goes into normal mode and then at 4.8k-5k then engine becomes much faster like a normal SOHC vtec. The thing is that i compare the engine with the engine D16Z6 which is a SOHC VTEC now my engine is the same but 100cc less and the bonus of VTEC-E if so my car is a hybrid VTEC or STAGE 3 vtec? i am tired of looking around for info but no luck my car has 114bhp stock can anyone help me???????????

Also i plan to modify it and have the following installed over the next month AEM v2, Nology Leads&Plugs, FSE Boost valve, Ecotek Valve, S/S Supersprint 4-2-1 mainfold + straight through exhaust + no Catalict convertor.

how Much power you think i will get with what i have mentioned and is it worth it ? Don't mention Engine swaps coz here in gibraltar that kind of stuff they don't do coz it costs the bomb, and no mechanics here are bothered + i don't have the cash.

Who in the hell told you about this shit stage 3 vtec? economic mode? All honda cars are economy cars therefore ALWAYS being economical. Its always in normal mode a car isnt retarded when it wants to be only when its broken. Your never going to find the info your looking for becuase I dont think it exists and the mods you listed your looking at like 5whp.

[civiclsi15]

Yes i know all Hondas are economic, but the are some with vtec-e technology(the one that the green econo lights up on the dash when cruising below 2.5k in any gear above second) and some with 2-stage vtec and 3-stage vtec these are only on SOHC. I Just Want to know what type is mine cause different websites say different stuff.

[civiclsi15]

Aslo i forgot that the gain with the mods i mentioned can't be 5hp
thats impossible , i had some with less mods than that (just a K&N filter and supersprint header with sporty exhuast) and he dynoed it and it was about 127BHP thats about 13HP

I was refering to wheel horsepower not base power and that green light you sure thats not your cruise control. I hate to break it to you but theres only one kind of vtec buddy they all do the same thing. Explain these so called stages could you please.

[civiclsi15]

I didn't mean cruise control , i meant like going for ride (cruising) (riding at low rpms below 2.5k if you want the econo light to come on)

Here a website which shall explain the VTEC stages to you. I thought the same as you until i got to research the Stages of VTEC.

I'm sorry but I find all of that to be false I dunno where you are from but it seems to be over seas but here in the states vtec is a big hype and being that its such a big hype and my uncle is a honda mechanic and I hang out at a speed shop it just amazes me how Ive never heard of such a thing that site is saying that vtec on dohc motors does one thing and then on a sohc does something else and then something else for another..... no vtec does the same thing for alll motors just using bigger cam lobes to sum it up I find all of that to be false. and driving under 2.5 rpm is totally dogging it real bad cruising rpms is 3 grand.

[civiclsi15]

Its true i just spoken to a Local Honda Specialist he says there are several VTEC types. And if you want Econo mode you need to be below 2.5k. Anyway here in Gibralatar you won't go past 2k unless you're overtaking in the incoming traffic lane. lolol like me.

the thing is gibraltar is very small, i mean very very very small place.

Any Way do you Know what Civic i have is it a DX,CX,EX,VX,HX?

its a Honda Civic 1.5LSi VTEC (Year 1999) hatchback 3Doors (EK3)
Engine Code: D15Z6 (is it similar to D16Z6?)

The thing is when i try to order from USA i don't know how my civic is referred over thier.

[civiclsi15]

one more thing, i have about £1250pounds i think thats about $2000
what parts can i order in order to improve my BHP?
Also is the 5bhp to the wheel noticeable?

[funkdaflex1]

well you say its a 1.5lsi we have a model here thats an si but its not on the 99 hatches just the coupe as for it being similar to a d16z6 yeah its just a point litre less. But to try and help you more do you have a sunroof, power windows,power door locks, did it come with cd player to cassette or just radio? Did it come with A/C? Basicly an EX has all of those things and the lower lines get less and less. We really dont go by base horsepower here its all about the wheel horsepower but 5 whp is noticable but when it comes to ordering stuff usually hatches have a category of there own like it will say 96-00 coupe and then be one for a hatch but who knows. Things to order would be your basics intake, header, exhaust, cam gear things like that.

Got bored, so I did a search.

There is stages to vtec, Well at least now there is I stopped payin attention to vtec along time ago. I didn't know they they made stages for the thing.
It seems that every link I found ended having the same stuff like whats in this link. Pretty much the same diagram and all that. eh

[civiclsi15]
