Go easy - I'm just a newbie...
I couldn't find what I'm looking for in the FAQs so I hope someone can help me out.
I'm in New Zealand and I've recently purchased a '97 Lucino (Import Pulsar) VZ-R.
I studied up on the specs of this car / engine before I bought it - 175Hp was a big attraction.
One thing I had expectations about was the VVL. After a week of trolling the net for info I have found that unlike VTEC - the inlet and exhaust timing change at different RPM.
I was a little concerned to begin with as I didn't feel that boost that you feel with VTECs and I thought that the VVL wasnn't working.
The car is extremely tidy and has only done 60 thousand KMs (40K Miles), so I'm assuming the engine is all working properly.
So anyway...
What I want to know is - factory standard, at what RPM does the VVL kick in on each cam? (totally newbie questions - I know)
In your experience, is the timing change noticable in power / noise ?
One VVL owner suggested that the inlet timing change is not really noticable & with a factory exhaust I wont notice the change to the exhaust cam timing much either - do you all agree?
Sorry to compare to Honda (and not that I like them, I dont) but with a K&N filter on a Honda you get an awsome intake noise when the VTEC kicks in - I am going to add a K&N Pod to my car soon. Can I look forward to a nice loud - deep intake noise? I'm not really expecting much Hp increase with a filter... but if I DO get any then bonus...
I've sorta figured out how the VVL works and where the solenoids are etc. Are the solenoids easy to pull out and clean? Is that ever nessecary? Can they clog up and affect the VVL performance? My oild levels and pressure are good - I know that can affect things...
I understand that you can change the preset RPM at which the VVL engages, how do you do that? Do you need one of these MSS thingees or can you do it yourself another way?
Thanks in advance - and please go easy, everyones a newbie at some stage!
Hey dude,
nice car! I can only answer a couple of your questions, hopefully someone else can answer the rest....
the standard switch points for the sr16 cams are:
Intake: 5600rpm & Exhaust: 6700rpm.
with standard intake and exhaust the change isn't that noticeable. the power curve is quite even, i.e no huge spike when the cams come on, so can be quite decieving.
with an intake/pod filter there can be some good gains - a friend with a standard sr16 made something like 10hp on the dyno with just that change.
be careful on the exhaust sizing on the 1600, too big and it'll start loosing power.
to switch the cams lower you can either use an MSS, or MSD rpm switches.
I'd suggest dynoing the car to see if there are any flat spots in the power curve as there may not be any gains from switching the cams earlier....??
good luck!
by the way, where abouts in NZ are ya?
Cool - thanks for the info. I did not realise that the exhaust crossover point was that high... to be honest I dont think I've even pushed her out that far. I've been waiting for a chance to get out of town and find a nice quiet country straight and redline every gear. I've only had it a week.
I'm not too fussed about changing the crossover point - after all, nissan put them at those RPM for a reason right? they no a little more than me (just a little... :-))
I hear you on the exhaust size, I guess it needs s certain amount of back pressure?
I preffer the intact noise over the exhaust anyway - and coming from an Auto SR18 primera the SR16VE is enough of a step up performance wise to keep me happy for a while.
I'm in Rotorua, what about you? I've seen one other VZ-R here... it has the full body kit with gold alloys, might be the Autech model (bit overdone for my liking.)
Yeah a friend had VZR pulsar and went quite well, has now "upgraded" and has an N1 spec VZR....we did the intake on his and he said it was pretty loud!
there are quite a few up here (I'm in Auckland) not so many of the Lucino's though!
yeap, even though it does make good power for a 1600 I think anything over 2" mandrel bent and you'll start compromising.....but that's only an educated guess
they love to rev. the limit is 8300 so make sure you use it now and then!
True. those N1s must be hard to get a hold of... apparently only about 500 made right?
I dont know what the deal is with Lucino / Pulsar... its just one of those SR-V things. I was stoked that the factory ride hight was lower and it came with a front strut brace ***. I test drove the SR18DE SR-V pulsar with its 185/70/14 wheels and 102Kw engine. I liked the shape of them but what a dog to drive! Then I saw this thing and was impressed that the smaller engine produced a thrid more HP... factory 15" alloys and stuff. Same Km's and the same price! Not really a difficult decision.
Well theres no point having 8000Rpm red line without taking her out there once and a while...
The entire time I was thinking "Dude, let'er rip. Scream that sucker!" LOL.
ha i was thinking the same thing. youve had the car for a week and havent taken every gear to redline . The_1_NEO post up some pics of your new car too.
I'm not sure I can post pictures... I only just got access to this forum today.
I've been a busy boy, this weekend I may get a chance to thrash her around a bit.
So I took the VZ-R out for a spin on the weekend. I redlined the first three gears (tend to run out of road pretty fast when you do that...) I didn't redline 4th and 5th 'cos the only roads I know that are good enough for those speeds are over an hours drive away.
Anyway - I was rather impressed by the power she puts out after 6000 RPM. If I had any doubts about this car they are all gone.
I'm putting on a pod filter this week - can anyone tell me what to expect in terms of torque / hp changes in the RPM range when I do this? This will be the only mod at this stage.
I had a S13 Qs Silvia for a long time and when I added a pod - the CA18DE lost a little torque in the low RPM but seemed to gain Hp in the higher RPM. Is that typical of this mod?
With all the 'real' horsepower being in the high revs in the VE - I'm not sure I want to loose any power down low.
The dillema is that I really like the intake noise and the look of a pod that matches that blue cam cover
I just recently picked up an sr16ve that I swapped into my nx2k...(nx1600 now haha) and Im actually running the stock de ecu with the msd window switch. If i can suggest one thing to u, it would be to get the msd window switch from www.jegs.com It cost me 100 bucks and I can switch the cams over simultaneously at a much lover rpm then 6700. I have mine set at 6000 right now but thats with the usdm ecu and my fouled plugs and Im running rich as sin! The msd also gives u an accurate rpm readout as opposed to our stock gauges.

Well - I installed the pod filter over the weekend and the VVL activation is definatly noticable. The intake sound at 5700rpm changes very coherantly and the exhaust timing change is much more pronounced.
Over-all the intake noise of the SR16VE is awsome.

Ohhhh yeah i miss the sound of my vvl, been so long since i have driven it, and my wifes wagon cannot feel or hear the difference at all with the cvt trans.
So yours is the 2 door coupe right??
Would be a great little sleeper
