Does anyone here know what top speed my 1.5lsi should be able to get to?? Also I have been told that on a VTEC-E you should feel a kick at 3.8K rpm? Is this right because I don't feel it.
This enginerange=>D15Z6, D15Z8 is known as the economic vtec's
they are 1.5l 16v with vtec.
they have 84kw or 114/115Bhp.
They could be nearly the same as the USDM D15Z (I don't know this for sure as i'm from belgium and i don't have the technical details from the D15Z engine.)
how they work.
the engine only uses 12valves when you are easy on the gas and stay beneath the 2500 rpm zone.
In 2nd,3rd, and 4th gear taht is.
In fifth gear they stay in te 12v mode(=econo=green light in console) until you reach the 120km/h mark.
also the Vtec kicks in @ 3800rpm and the redline is 7000rpm(could be 7100 also)
as far as I know this engine doesn't seem to be available in the US.
only in the EU regions
I hope that this info could be of some help in finding out which car you have.
If anyone of the americans on the forum here could lay his/her hand on some tech. info about the D15Z engine and you can/will send it to me you would have my everlasting thanks.
Because: the D15Z range of our EU models is NON tunable.
I mean there are no known parts for it.
So i'm trying to find as much info about the D15Z range as I can get.
Because I want (like most of us) more power.
(Engine swapping is NOT an option in belgium)
Love y'all
They've made the D15Z1,D15Z3 (both VTEC-E) and 90Bhp
then they've made the D15Z6,D15Z8 (both VTEC-E) and 114Bhp
all of these are 3stage VTEC's don't be fooled with the E.
The E only stand's for the 12 valve thing I explained earlier.
And be sure that the 3800 VTEC kick in is correct.
That's defenatly right.
Now what you were saying about the 2stage VTEC is in some way correct.
Honda has mede a block with 2 stage vtec also. with 1493 cc.
but that is an engine only produced in 5-door EU models.
You say that yours is an 3 door so it's surely an 1.5 VTEC-E.
with 3 stage VTEC and so on.
You say faster than 10.2!!
Could be in your case
Because I drive an 5-door civic which is heavier than the 3 door brother.
and even A 3 door 1.5 isn't (verry)fast.
Normally the 1.5 vtec's are economic thingy's like the american HF's.
They also reach their top speed in 4th gear.
So the fifth gear is pure economical.
That's the bad thing about these cars.
The gears are so long that the car loses much of it's "spark" when your flooring it.
I'm trying to find out which gearbox could fit under mine so I have a real 5-speed tranny. (now they are 4gear with an 5thfor saving fuel.)
hope this helped some more.

I have done it, but there is no need to go 99+. If you want to go faster get a new engine.
i once topped out an insight... 105mph.. and it took ages to get up there... i had to find a country road to do it. didn't have enough room on the interstatei have the d15z1 vtec- motor, and i have 92bhp, my car tops out at 103mph in 3rd
