If you want me to use the search button, then how am I supposed to look that up? Seems like kind of a broad topic to type in...it was a good paragraph. Thanks for your help erik.

BTW, I am talking about the "classic question" thread.

He meant to SEARCH on the differences..and you would indeed find some answers...

But what am I supposed to say when I am searching.. I can see it now in the search button..."What makes a 91 cam in a 96 200sx better than a 91 cam in a 1991 sentra se-r?" Right....lets see, I would only pick up about 103217483294738124923748923 replies, 99% having NOTHING to do with the topic. If these dictators wish to have the search button be the answer for everything, simply close all forums/threads, and devote 100% of their maintenence time to improving the embarassingly sucky search option. Shouldn't be a problem since every single question has already been answered.

hmm...

try high port vs low port

or b13 and b14

best sr20de motor

or....

Justin, take your time, and just go back through old threads, there are numerous ones that talk about B13 and B14 differences.

Try some of the keywords Black200sx laid out for you, there is a lot of info out there, you just have to know how to find it.

Ok thanks black200 that helped. I really couldn't think of a 2-word summary to help me search for what I was asking. The question wasn't really which is better, it was why doesn't a 91 cam in a 91 car produce more horsepower than a 91 cam in a 96 car, or something in that nature. I'll look tonight. Thanks guys.

Crono1321, to the best of my knowledge....

The 91 intake cam is *slightly* more aggressive then a 96 intake cam. B14's have OBDII emissions, while B13's have OBDI emissions. I believe they made the B14 cam *milder*, so it could pass the more stringent emission laws.

As for power, I think the 91-93 intake cam makes the same power until like 5000 rpms. Then it slowly adds power until you gain about 6 horse over a B14 intake cam.

Hope this helps or answered your question.

96 SE-R

you could also try:

91 cam, 200sx

91 cam, B14

91 cam upgrade

try 'intake cam' as it is the only one necesary to change.


I think it had a different grind that was 91-93 but changed in the 94 models

I think his original question ***, was why if the high port is a better motor....does it not make more power with the cam, like the low port does...Im NOT.I repeat..NOT trying to get a debate going on which one is better..I think the high port has more potential when it comes to high HP numbers..period.

but it looks strange..140 hp...high port...and then on the other hand you have 140 low port with a milder cam, and more emmissions...it is simply food for thought. I know the high port head flows better than the lowport...

Yeah, I agree with that, it doesn't seem like the lowport should have the same 140HP that the highport has, if anything the lowport should have about 135HP.

This is from memory since I am currently at work, but here is how the SR20's dynoed per SCC back when they did the comparo of the roller rocker SR20 and the non-roller-rocker SR20 motors.

'91-'93 (high port)>>>>>>>123 HP
'94-'99 (low port)>>>>>>>>118 HP
'00-'01 (roller low port)>>>>125 HP

So the high port did generate more power at the wheels than the low port even though Nissan stated 140 HP for both.

wow.very interesting...

Which issue is this in?

Should be the JUNE-1999 issue with the write up on the 2000 Sentra SE 2.0.

This is also the same issue with the Cam comparisons that SCC did.

:D

The engines make the same PEAK hp(factory rating)but the obd1 has a higher redline. The 91' cam simply gives the b-14 better breathing up-top. Maybe the B-14s make 140hp maybe they don't, the fact remains that Early intake cams gives gains over the later cams. IMO save up and just get S3s or S4s which give gains over ALL stock cams.

Don't forget. The OBD-II G20's ('94-'96 low port) also have the higher redline (7500 on manual) with the less desireable intake cam.

Black200, you hit the nail right on the head. My question was that I was wondering why the high port makes the same power as low port, if indeed its "parts" are (and I use this term loosely) "better." To me, if you have a better cam in a better car, then why does it still only make the same 140hp?? Would seem as though it should be making like 143-150hp?

I think Skyliner may have hit on a good subject.of actual dyno'd to the wheels HP.as oppsed to Nissan claimed HP.

But, I would also like to see what a stock B14 would do with the 91 cam, and a G20 ecu that has the 7500 redline..just a little but "better" comparison I think. I know when I got the cam, my car "felt alot better.then adding the ecu was even better.

As for just getting S3's/S4's..well..$585.00 is just a little too much for 11-15 hp...(varies) at this time for me...now..when I find that seet deal for less than that..Im all over em and will get them. But..that isnt the case of this thread..:D

If you can get your hands on the June SCC issue with the cam comparison, there is a little write up on some of the reasons for the differences in the article on the 2000 Sentra SE.
