Some answers I can not find.
-Can I use my lsd tranny/clutch kit/flyweel from my sr20de?
-Do sr20de axles work if I use the sr20ve tranny?
-Are both shift linkages the same? wich do I use?
-Does it matter if I have the highport or low port ?
-Can I use my lsd tranny/clutch kit/flyweel from my sr20de? Yes
-Do sr20de axles work if I use the sr20ve tranny? I don't think 20VE's came with manual transmissions.
-Are both shift linkages the same? wich do I use? See above
-Does it matter if I have the highport or low port ? Nothing significant
Guys, I need the wiring diagrams and the links posted dont work, does anyone has the diagrams that could give me a hand. I have the VE already installed in the car, the problem is that i need to activate the VVL and also wire the VE's distributor. Also if someone has the wiring diagram of the VE's ECU will be highly appreciated.
What I am planning to do is to install the stock VE ECU using the DE wiring while I get the chance (and the money) to order the Calum, cause I have another things to do to the car (tires, clutch, gearbox is leaking :S:S)
I have an egual problem. I ordered the SR20VE for my B13. The manual trany from my old SR20DE is allready installed. The harnes is allready here. But what the hell does this 2nd "ECU". Is it necessary for the engine?
There are 3 conectors from the harness to the car. But I could only identify the use of two of them. The third is linked to this cryptic "control unit". What is the use of this?

Many Thanks, Sylvio
Bro quick question: Are you using the VEs harness? or the DE's? At leats in my case the VE wiring came complete including the part for the automatic gearbox, which uses a different ECU.
I recieved the whole thing: VE-Engine; VE-Harness; VE-ECU.
And that`s it, what I was asking for: the automatic gearbox! Is it necassary for the swap into my NX2000? It means can I cut all the wirings to remove the automatic gearbox electronic because I want to replace the automatic gearbox by the old SR20DE manual transmision?
An other question: Which MAF do you use? I think the DE MAF is too small! Where can I orden a (cheap) VE MAF?
It is not required as per what I understand. I purchased the engine + VE harness + VE ECU and VE MAF.
Indeed it is better if you use the VE MAF.
In my case I was going to use the VE's harness but it was more complicated than using the DE's harness, so im using the DE's harness and I just replaced the connectors as necesary (Maf, distribuitor, water temp. among others)
I have some wiring diagrams that may be really helpful. PM with your email and I can send them to you.
In m case I have a B13 SE-R obd1. If your NX2000 is a 1991 the harness is pretty much the same as per what i understand.

The idle control valve (I forget the name of it right now) is on the intake runners, not the side of the engine, so you need to extend the 2 wires for it.
Use your choice of maf, and get the ecu programmed accordingly.
Use the DE distributor, so no wiring to change there.
Wire the solenoids to an external switch, like the MSD 8969. One wire from each solenoid goes to +12v. The other wire from each goes to the MSD switch.

In my case I am using the stock VE ECU, and I got the VE maf which has better airflow than the DE's, as well Im using VEs distributor.
It is already installed and running on an SE-R B13 1991. I just had the chance this week to activate the solenoids, now it is activating at 4800rpms.
Next payroll will be for the new clutch since the one I am using didnt last that long as I would expect and then I will be doing some dyno runs to see what is the current whp.
My concern is the compression. When I bought it it had 200psi per piston, this in cold so it was supposed to increase, but instead it dropped to 195psi. I am checking with my mech what could be the cause. I had to replace the valve seals cause the smoke emission was big. After the replacement the smoke stopped but the compression went down.
The VE harness and ecu are OBDII, correct? What was your reason for wanting to use the factory VE ecu?
C
Nope, they are OBD1.
I had 2 reasons: I was planning to leave the car as stock as possible. I know a guy who has the VVL being activated by the ECU, and I was waiting for a friend to bring a Calum Basic board and have it installed with a guy here who is specialist but in Hondas, so I wanted to wait and see how it comes out.
This brings me to the second reason: emissions. Here there is a very restrictive policy for emissions, you have to take the car every year to a technical revision by a company hired by the government, this is pretty much a pain in the rear. Not even my stock DE passed without having to do some tweaks. I have a couple of friends who had to do all kind of stuff because their cars would not pass the emissions test, they had piggy backs (SAFCII and NEO) and they could not drag the emissions down. In the other hand the guy with the stock VE ECU passed without mayor trouble the test.
The worse part is that they evaluate your car not by the fabrication year as it should but by the year the car was imported. So in my case even though my car is an 1991 model, they evaluate it based on the emissions of a 2005 model, that is when the first owner brought the car from the US.
My car is for daily driving, but I like to race every once in a while so I was not planning to invest a lot of money on it, cause I need fuel economy more than whp. In any case I am planing to save some money and purchase a calum board and replace the VE ECU, but I have some other expenses to think about now.
i have a 1998 200sx(1.6L, blown engine). i got a sr20ve engine, in the area i live in i was only able to find a 1996 g20 auto transmission luckly at the salvage yard. all auto part stores either didnt have anything or had to order parts for any sr20 engine. so i made sure the engine and transmission worked , and i get them for spare parts. couldnt find a transmission for same year,make,model but for 2.0L. i already got the harness and ecu for a 1998 2.0L, and the transmission computer from the 1996 g20(dont know if i need this for sure yet). would this be a fairly easy swap, or a pain in the ass???? please help with advice.
Ok so just to have it clear you are planning to install the G20s automatic transmission?
First off, if you have a GA16 engine, you will need the motor mounts, you can use the ones of the G20, although im not quite sure if the automatic transmission mount is the same as the manual.
It would be better if you can get an SR20 or SR18 trainy. You can get the one of a Sentra B15 SE (2.0L), but it is up to you if you want to drive MT or AT. (personally i dont like AT)

i was waondering i have a 93 se the i swapped a sr20 de in but i want to up grade to vvl and was wondering if it was nessesary to swap the ecu to ?
There are 3 ways, in my case I swapped the VVL stock ecu, this cause I was looking to have the car rolling without having to install a SAFC(mainly because of the emissions test that takes place every year here), and the fact that I needed the car rolling ASAP (I swapped the engine and had the car rolling with a friend in 24hrs straight :P) however my plan was eventually to get a calum chip to mount it on the SR20DE ECU.
That is actually the best option, you can get a calum chip, have someone putting it into the SR20DE ECU or ship your ECU to Calum so he can do the work for you (however he is like missing in the twilight zone as off this moment (kinda difficult to locate:P)). Advantages: You can do a very good tune, move the rev limit up to 8200 and some other tweaks (specially if you get the Calum RT)
Third: And not my favorite: Use your stock SR20DE ECU, plus a SAFC II and a window switch to open the VVL (I had to do it as well)
hello guys
i've buy a sr16 ve and i want put on a sentra gxe 2002
i've buy a new sr20de transmissions to fit easily on my fu*king 1.8
my question is :the sr16 clutch and flywheel fit on my new 2.0 transmission or im oblige to buy a new sr20 clutch and flywheel
Im not totally sure but I think all Sr16VEs come with manual transmission, if that is the case, then I think your flywheel will work cause the Sr16 transmission is almost the same (installation wise) as the Sr20DE, however the SR16 has close gear ratio, in short terms it should work however it is recommended to balance the flywheel (or check if it is fine at least) and get a new clutch and pressure plate will be the recommended (unless the ones you have are new)
