does anyone here know the mechanical differences between the SR20De and the SR20DE in the primeras? not hp, torque and so on... but what makes it a De or DE?? (everybody with me here??)
I've got the De and want to know how to make it a DE... to speed it up a bit

um, as far as I know, making it a capitol E does nothing. But the primera motots have 10:1 compression, stainless exhaust manifold, intake manifold is a bit different too, and I believe a little better cams.

it's like this: the primera up to '96 you could buy with either the De-engine with 125hp or the DE (GT) with 150hp. the '97s to '99s you could get with either De, 130hp, and DE (GT), 150hp. the new model only comes with one of the 2-liters, with 140hp (like the US g20?). now, anyone with the proper knowlegde of the differences?? (of the p10 engines..)

About the only thing I could find apart from that link up there was that the engine you speak of with the lowercase "e" is in the Sentra. So it just might be a smaller, base model engine for the G20. Hope that helps.

I don't know where you're getting you're info . . . maybe you could share some of your sources to get the rest of us up to speed.
I believe you're off . . . incorrect, that is . . . but I've been wrong before. Anyway, the Nissan powerplant designated SR20DE, is a 2 liter engine regardless of what you may think the output is . . . Actually, an engine rated @140hp, like the SR20DE will put out approximately 125hp to the wheels . . . Maybe your referencing Sweden specific models ???? |

I agree with thaa here - there were different SR20-s available in Yurp - SR20De, SR20DE, and SR20Di. The power output is 125, 150, & 115 hp respectively. My guess would be there were differences in cams between De and DE, but that's just a guess. I've seen the two engines mentioned in my service manual, butI did not pay much attention (will take another look as soon as I get my hands on it - it's not at my home). Thaa, I would suggest going to your local Nissan dealer and asking: I would think they are more cooperative than the dealers here. Or you can compare the part numbers for cams for the two engines.
Hey, how come no one answered my question at SR20DE vs SR20Di?

not sure whether there is a valid difference between a "De" and "DE"
but based on Nissan's engine codes... an SR20DE is an "SR" family engine which is 2.0L which is where the "20" comes from. the "D" stands for dual over head cams, and the capital "E" stands for multiport fuel injection. the SR20Di stands for SR family 2.0 Dual overhead cam with throttle body injection which is a lower case "i" still.. i cant find the meaning a lower case "e" for the fuel delivery field... maybe since the capital "E" is a multi port... the lower case "e" is a single port fuel injection? ...this is just a speculation.. dont know if such a thing could or does exist.... anyhow.. if there actually is a difference.. the "e" DOES mean a fuel delivery difference as nissan engines follow this designation.. [engine family][size][valve train][fuel delivery][turbo] the turbo and fuel delivery are not always present.. if there is no turbo field then there is no turbo.. duh! and if the fuel delivery field is not present it means the engine has a carborator |

No SR engines have been *ever* equipped with carburettors. It is more easy to mistake TBI for a carburettor (you should have seen my face in the first two weeks after buying the car - I was sure I got deceived). I stand by my guess that the difference is in more agresive cams (what else can it be if we consider that both engines have multi-point injection!!!). Try the Nissan dealership - they may know the answers.

hmm... do people not like to read? i'm not forcing you to listen to me, but please at least READ what i said...
i just explained how nissan engine codes work.... an "e" cannot mean carborator... a nissan engine w/o a fuel delivery "letter" would be one equipped w/ a carb... for example lets make up our own "XY" family of engines which has 2.2 Liters... and lets say its dual overhead cam.. with multi port fuel injection... the engine would be called XY22DE if it had a carborator... it would be called XY22D ...still not sure if lower case "e" means anything different than an "E" in the "fuel delievery" field of the engine name but if it does.... IT HAS SOMETHING TO DO WITH THE FUEL DELIVERY BECAUSE OF ITS PLACE VALUE IN THE ENGINE CODE.... Last edited by b-b00gie; 05-23-2001 at 06:18 AM. |

lots of input here...
the lower e in the SR20De still stands for multipoint injection, but as the power is only 125hp against 150hp (the european GT), there have to be some mechanical differences between them.. now, is it the cams, compression ratio, the ECU or everything?? guess I gonna have to speak to my nissan-dealer and see what he says... also, I will post his answer here to straighten things out a bit...
