QG18DE shared parts and performance parts...

[andrew.hampton]

I just got a 2003 Sentra GXE and I don't know of very many parts for this particular engine. Which parts that a QV25DE would can be used on a QG18DE? I imagine that there would be a few...

[VMPhil]

its QR25DE and QG18DE.

the only thing that bolts up IIRC is the Cold air intake which make take some finangling and some slight modification but people have done it. exhaust and header is a completely different animal.

[andrew.hampton]

so basically NOTHING can be swapped from one engine to the other...that's a let down...what about from an SR20?

[VMPhil]

not sure, Ive never owned an SR20, perhaps someone else will chime in.

You've kinda got to be willing to get your hands a little dirty if you are wanting to modify your car. Not everything is going to be just plug and play... and even when it is, its usually made in china and requires some sort of modification anyway

Why not try and get the cold air intake and see if you can get it to fit? If you run into any problems, post them up and we can help. Take pictures while you're at it and it can be a guide to anyone in the future that wants to do the same thing.

The reason why I ask is to see what kind of potential the stock engine has compared to its other counter-parts. The PURPOSE of my asking if any parts from the other engines are transferable is to further understand the tensile strength of what's there now...and now I'm not so sure about it...I guess the only upgrade would be to swap an SR20DET or SR20VE into it. But this won't be done for a LONG time. The warranty will not cover THAT kind of work.

QG parts are all over ebay dude, why would you want use SE-R parts?
no real need to move SE-R parts to a QG.
If you wanted to know for comparison sake well...
Even Turbo'ed these engines dont make a shyt ton of power unless you do some major work on the internals. The only QG setup I knew of first hand (as in I talked to the guy who did it, but there were a couple of others out there whom I have never talked to) was pushing about 180whp which is about 210bhp.

A fully Bolted 2003 SE-R was dynoed at 198whp which is about 235bhp (calculated @ 15% loss).

[andrew.hampton]

If that is the case then an SR20 would be a better way to go. I suppose at this point it's a matter of which SR to plan for. Whoever reads this thread that has ANY knowledge of the SR20VE, please chime in.

The swap will be a pita you need to get a 95-97 200sx SE-R B14 ECU to swap in and redo the harness on your car to get it to work. The easy part is I think you could get 00-01 SE SR20 mounts, at which point an SR20DET or SR20VE will mount up with those. Then you will also need 00-01 SE axles, transmission (pita to find), and shifter assembly. Not really sure about the specifics about the VE but I think you'd need some sort of RPM switch to activate the VVL solenoid at a given RPM. Anyone feel free to chime in if im wrong. If you do an SR20 swap though keep us updated!

[andrew.hampton]

After what I have read about the QG18DE, I'll definitely pull an SR. My only problem is deciding which SR would benefit me best for what I want it to do. If an SR20VE would be a P.I.T.A., would it be easier to swap in an SR20DET? I could also try an SR20DE and build it for high-compression since those engines are practically a 'dime-a-dozen'.

Either way DE, DET or VE you still have to get the B14 ECU then you have to mess with the harness to rewire everything so that you can run the engine off of it. Not only that you have to get it reprogrammed for what ever engine you decide to use. Jim Wolf Technology does reprograms for B14 ECU's or you might be able to find a used calum ECU (which is a chipped ECU that you can change chips and programs on by burning new Bin files onto them using a moates burner). I think a DET would be easier because you dont have to worry about the VVL solenoid activation. A DET would also be bigger bang for the buck because it wouldnt be as expensive to purchase a DET as a VE seeing the VE is a pretty hard engine to find. Stock DET's depending on which one you get usually have about 205hp which will definetly give you some pep outta your sentra. The VE is rated at 185ish if I remember right.
