does the mr18 have vvti ? and if so when does it kick in

Yes, IIRC around 3500-4k rpms.

ok so its called iirc ?? what exactly does that stand for

and what does it do??

If I remember correctly.


Continuously Variable Valve Timing Control System (CVTCS)

Some info on the 350Z system:
http://auto.howstuffworks.com/nissan-350z-design5.htm

hmmm maybe theres a controller out there to be made lol like the vtec controlers cause honestly it really does help i had one on my old honda

what exactly does a vtec controler do?

its alows you to set when vtec will kick in and when you change it like that it makes it kick in harder in mine it made it to were in first and second gear the wheels would start spinnin lol plus the turbo lmao it wasnt slow and it was also a 1.8 with vtec

nice sombody should makr tht for the v

well i know they make it for the toyota celica as well and from some of the rumers ive heard the 1.8 in 07 and up nissans were designed from the toyota versa so it might work ill have to talk to my uncle who is a designer for toyota and see how close they really are

ok after doing some research it is but isnt like vtec in a sense does the same thing but it is constant you can be at any rpm and pin the accelerator and it will kick in but it activates a secondary intake valve which alows more air and fuel for more power in the top end so if you get a throttle controller its will cause it to kick in faster because that opens the butterfly faster which in turn will make it kick in a little faster


i pulled this directly from the nissan site

Continuously Variable Valve Timing
precisely modulates when intake valves open and close, factoring in throttle position, vehicle speed and engine rpm. The result is outstanding thrust off the line and deep reserves of passing power. The Variable Intake System similarly lets the engine "breathe" differently in changing conditions. Again, there's plenty of thrust in the low range; then as speeds rise, a second, shorter path opens in the manifold, allowing more air-flow to the engine.

wait so why did they put this in an "econobox" secondary intake vlave sounds to me tht nissan was tryin to mkae somewat of a sleeper car maybe they wanted this car to be modifed lol or they were juss copying honda. and i like tht its not like vtec tht its a certain rpm its wenever u pin the gas pedal i say this is pretty beast

after looking around it is on all nissan cars well newer ones anyways i think its gonna be there new thing like vtec cause even the 350z has it as well so idk but i like it makes it a little more controllable than vtec

wait so u just floor it?
i like tht we have dohc to

yep basicly

so in a way were kinda driving a low powered civic si cuz the civic si has dohc and vtec and we have a better verson of the vtec

basicly lol stock vs stock it would be close i know itll beat a integra lx with full exhaust and intake and gutted witch is a 1.8 dohc non vtec

yah so in a way if we put a little bit of modifacations we could beat the sh**t out of the civic si this is making me happy now imma race thos a** wipes tht tlk s*** about my v saying its slow even though its faster than ther civics the regular civc not the si wit a cherry bomb muffler lol i love my v!!lol

Not

Going

To

Happen

im talking about stock civics not the si's wit there cherry bomb mufflers and yes it will happen

Well yeah, stock older civics have like 90hp, so its possible.

no that old i seen versa beet some of the newer civics and man stop hatting on v's

I owned a Versa for about 2 years. I'm a realist, they aren't a race car. They can be made to handle pretty well, but until a good FI option is available they will be slow. They are better for hp/tq in their class (Fit, Yaris, etc), but that was just enough power to get out of its own way.

Another mr18 question.
I noticed the throttle response just isn't as ...um...responsive as my old Sentra 1.8. I really notice it when double clutching on a down shift. The ratios are so close that it doesn't need much throttle to match the revs anyway, but it definitely needs more than a little tap to get the revs up.

Is this normal?
Is my fuel pump on it's way out???
Or am i just spoiled by the old sentra
08v

yeah its i ltiile weak on the throttle u should get the throttle contoler im getting the ntd one its so beast tango has the ntd he says tht it works rlly good

yesa a throttle controller will help the reason it is laggy is because its a electric throttle your sentra was most likely a cable throttle which has no delay between throttle and pedal with electric there will allways be a delay

i kinda like the electronic throttle but its awsome wit the throttle controler

it really does help thats gonna be my next mod

Thanks guys, that sounds awesome.
I'm not surprised about the electric/electronic throttle.
Does a throttle controller affect fuel economy significantly?
Gas just broke $1 per litre again here...
Usuaslly over $40 to fill 'er up.

m no not rlly on the ntd one there four eco modes normal mod and 7 sport modes but if u cruise in ec 4 and race in sport 7 its pretty beast
