they both make 140 crank hp. but people say the highport is a little quicker...i love my lowport, plus the whole head is more efficient, the hp remains the same because the lowport has a less aggressive cam grind, so if you put the intake cam from a highport in a lowport you get about 5-7 hp more, it is noticable.

Damned interesting. Is there a ifferance in the performance? it seems to me that maybe the low port might keep a little cooler.....hmmm.
I have heard the low port engine with the high port cams installed is the best USDM setup you can get...
the low port makes 140 hp just like the high port, but I believe I read that it's a cleaner engine..so then when you put the "dirty cams" on an engine that has "clean cams" and still puts out 140 hp....theory...
someone delete this if I'm wrong...

huh? the highport intake cam is more aggressive than the lowport intake cam, if you consider this "dirty". the exhaust cams are exactly the same. it is proven that the highport cam in the lowport motor makes about 7whp more than stock.
The highport head has more emmissions because the injectors were further away from the valves, so the cam will have minimal effect on emmisions I would have thought.
highport is quicker cause its sitting in a lighter body!...but the lowport 94 sentra SER is about the same so there should be no difference. Plus if the lowport gain 5-7 hp with the highport cam, that makes the lowport 147 compare to the highport 140!!! You have to think that with the larger cam, the highport only make 140hp and the lowport with its smaller cam still makes the same...I go with lowport!

Don't take offense, but you don't know what you're talking about. The SE-R was pretty much the same weight from '91 to '94. And who said that the high-port was faster? I've disproved that many times (not in the form of documentation, but in races with B13 owner who have high-ports). It ultimately depends on the driver, not only the type of head you got when doing a stock-to-stock comparison. Get your facts straight man. The cam stuff, you are ok with, but that other thing you said... it's a bit laughable dude.

no offensive taken but you should learn to understand what you read before you post! "but the lowport 94 sentra SER is about the same so there should be no difference"....
from 91-93 its all high port, and late 94 sentra are low port so in term of weight, there should be no difference. But the majority of lowport are 200sx, and if you check, they weight more than the 91-94 sentras...and if you ever run before you should know that weight makes a huge difference!! Also to answer what you say about racing b13 owners, hell i can beat a formula 1 racer with my 1.5 tercel, if he cant drive!! So we are not talking about drivers, just comparing the lowport and high port. basically sentra to 200sx.
OK OK, you guys have good arguements, but what is the real question is how much does each head flow on a flow bench? Anyone done a flow bench on low port vs high port? Is a low port s14 and s15 head the same as a sentra low port? There is a big arguement among 240sx people of the s13 engine vs s14 and s15. besides price, which one really flows more???

IIRC, there is no such thing as a lowport DET motor. The lowport must flow a bit better than the highport, because they make the same stock HP and the lowport has a less agressive intake cam. This is why the highport intake cam will make like 7whp when used in the lowport.

The low port DET engine comes off a s14 or s15, sorry I shoulda have mentioned the rwd sr20's, most the discussions here are assumed fwd. Those low ports have vtc.
