Thanks!

What motor do these have ?

[niiCk]

k20 im assuming since its a sport

[Waternmo]

K20Z2 to be exact, this motor's vtec suposedly kicks in at around 4500rpm, but u dont really feel or hear it for 2 reasons. 1. k20z2 is classified as low output K20 like the CRV's low output K24, so only the intake valves have Vtec, 2. its a little different to the high output K-series, this motor runs with 12valves during normal driving with 4 intake valves particially open to achieve the best lower rpm torque, once it reaches high rpm, the 4 intake valves are lifted and all 16 valves are now opened up for high rpm power.

do you think this is linked to the rev limited at standstill? i was dabbling with car this evening and never noticed it was limited at standstill to around 4000rpm. might be unrelated, and just a safety net by honda.

[curtis265]

it's limited? I can rev my r18 all the way to redline in neutral..

[blasdf]

maybe it's in the FD2. mine won't go above 4000rpm in neutral or standstill with gear selected but clutch in. it's like a launch controller. i never noticed it until my cars battery fuct out the other day. my mate and i jump started it, and i put my foot down. it just start bouncing slightly at 4000rpm. thought, WTF. but even the new battery it does it.

but in saying that i never once put my foot down and launched my car revved high, i always reved it around 3-4k anyway as that was the default revs i did on my old cars to get a good launch and no wheel spin.

does anyone else with an FD2 have this with theirs?

The reason why it wont rev past 4000rpm is because your motor isn't warmed up yet.
Drive for a while until car temp is halfway

Props to Honda for doing this :thumbsup:

you sure? i took the car out for a big spin around the back roads. pulled up to an intersection when it was warm, and it definitely still sat at 4000rpm.

do you have an FD2 to confirm this? Maybe something is stuffed on my car haha

[blasdf]

and yeah i shoud have said, it revs right out when in gear. and i'm also aware of cold engines, my previous hondas never engaged the vtec kick until the engine was warm which i assumed was a safety feature, but i never rev out a car when its cold anyway.

its limited in neutral so dumbasses dont rev dump and kill the driveline

[blasdf]

fair enough, although these cars would usually break traction straight away so i imagine it would be quite hard to break any diffs or such. none of my previous cars had trouble from a bit of power through everything. but in saying that i never previously ever noticed my car had this as i don't rev it and dump, as what i said about you break traction and don't go anywhere.

it depends. if you have semi slicks on, it will stick to the ground much more putting more stress on the driveline. you are only basing it on road tyres on the road!

The fd's have no diffs....

[FallenAngel]

and to answer your first question, its at 5700-5800rpm depending on the conditions.

[curtis265]

I thought every car has a diff?

[xqwzit]

fd2 vtec is at 4000rpm.
the exhaust sound changed when i have my straight pipe before.
its not a crossover like b series but you can def tell its vtecing :)

You serious? I've never noticed on my friend's fd2 until its 5700 like the fd1...
Guess he needs an exhaust lol

[white_ep3_civic]

The rev limiter is normally just before vtec. My ep3r did it at 5500 rpm which is where vtec kicked in and in my euro it holds at 4500rpm where there is a change of note in the exhaust when underload

[Mr Abzii]

Same thing with me, My FD2 will rev till 4000 even with the car warmed up. I only noticed it after i got a CEL but, dont know if that had anything to do with it.

[xqwzit]

Fd2 vtec is at 4000rpm. Exhaust changes note same as euro.

[integragsi96]

my Prelude VTIR H22a is limited at 5100 and thats just before vtec crossover.
however i wouldnt bounce it as it can cause damage whether its warmed up or cold.

[Areis]

wow i thought vtec engaged at like 5-6k revs.... and i drive an fd2.. oops!

[EGB]

FD2 Has electronic limiter whilst under 3-4kph, will only rev to 4 - 4.5k rpm.

lifes too short to longboard.
