JDM Civic EK9 Type R CTR B16B N1 Crank Pulley


then why lot of people with other make pulley broke their engine ? i know 2 with unorthodox.
i know correct balancing should be crack-flywheell-clutch-pulley

how do you know the pulley "broke" the engine? and what do you mean by "broke"? what part failed?

when ever an engine fails people are always quick to point a finger at a specific part without knowing what really happend.
 
crank rods broke,oil was ok,1 engine was stock the other with cams and pistons.
i dont trust those things but to be honest i know a guy with stock b16a and unorhodox pulleys he has them almost 1 year without problems.
 
I don't trust those, including the N1, either. Like I mentioned, I do have a friend with a GSR motor running the N1 pulley without any problems for many years now. Just a piece of mind for me I guess. Plus I want my A/C. :)
 
All my mates that broke their engine using the n1 crank pulley have something in common. They all 1.8 liter engines +! :blabla:

5 of them broke their engine, all of them running n1 crank pulley.

3 1.8 B18C engines
2 2.0 b20 engines

One B20 didn't even last a track day, he broke his engine on the tests! :wow:
 
I am running a 1.8 motor as well, no N1 pulley for me.

blinx, what I think about the crank pulley either it is called N1 or has no name, is that it seems this mod to be the most dangerous from any other, based on what most people get at the end...Perhaps it requires being aware of other parameters in detail to do it that doesn't seem obvious to us. We just think that by putting that pulley on its ok. What I want to say is that, cams can be installed by an elementary engineer who just needs to know where and how to put them correctly. If they are not properly tuned, this will not affect the engine safety but only the performance, but even an experienced engineer may not be aware of what to consider before installing the pulley. It might not be enough to know how to put it and also few things more. Pulleys or cranks are not problematic, but people are!! It seems being 99% pecent aware of the situation is not enough :( Unfortunately, there's exist many 99% professionals out there, thats the problem :) That's my opinion, I might be mistaken though :nice:

i agree with everything you said, except it is possible to damage your engine with too big of a cam (piston to valve contact), but i understood the point you were trying to make. :nice:

Why to have "piston to valvle contact" when you properly install cams that were made for your car? :confused: I suppose you refer to the case where you don't upgrade your valvetrain when necessary??
 
my n1 crank pulley will be installed today :nerv:

for example if you get extremely high lift cams, and really high compression pistons with big domes it is possible for your pistons to hit your valves, then again this means you have the wrong combination, but it has happend many times in the past. piston to valve clearance is usually only a problem with huge race cams or frankenstine motor builds...
 
So, using street cams like S2 Stage I or Stage 2 such problem will not occur in case you change your pistons, right?, because I made the thought to change them to say the truth :nerv:

yeah, usually milder cams are fine on stock shortblocks, its the highlift cams you want to be worried about, its best to discuss your ideas with an engine builder or the cam manufacturer imo just to avoid such a thing.
 
Reviving an old thread.

WHat are the actual advantages of an N1 crank pulley?
Had a friend that removed both ac and ps and swears it accelerates faster. is this true?

Less rotating mass, like getting a lightweight flywheel.
 
I'd hope the N1 Pulley causes no problems, I've had one on for almost a year now.

I'm guessing the damper in the original one is the rubber bit that is sandwiched beetween the inner and outer metal parts.

Correct, just be sure to replace the N1 pulley with a standard one if you ever stroke your motor.
 
does any one run this pulley on their b16a, i was wondering if this would be safe to run? the b16b has a better balanced crank than the b16a, so is this a bad idea to run? thank you.
