Nissan Primera P11 GT SR20DE --> SR20VE Questions

Hello.
i hope this thread gets some attention.
I need information about this swap.

If you dont want to read my mind, the questions in this text is colored blue.






So, the worst thing that happends, are when your P11 GT engine is
starting to worn and you can feel power loss.


My current engine is bleeding inside. and the car smokes more and more every few months.
The engine is actually in "good" condition tho.
It still performs really great and have never failed me. NEVER.....  NEVER!

Sometimes when i drive, just at a totally random moments, my car just feel much stronger than in years, it gives a real nice boost after 4k rpm and really put out some. It feels great.
But usually it feel like i lost alot of power and it generally isnt as great as it used to be.

well its still powerful after 4k rpm, but often its just "slow", that i cant feel its drag as good as i used to. its like its slightly resisting. Been like that for 2-3 years and getting worse.


I dont know if this is a problem i could look deeper into and fix, but right now, its not
the powerloss that  bothers me but more the fact it has been doing a good job for too long,
and that i dont know if i could trust the engine on a long road trip really.
It probably wouldnt fail me, i just got too much faith in these engines to belive it would,
but still, i should be careful on driving far far away from home.




I decided to (some day in the future) put a VE Neo VVL in my primera p11
to replace todays 220k SR20DE, which by then probably will have over 300k lol.
I might do it soon tho, not sure yet, about if i would get it street legal here.

I could lie to them, and dont tell them about the engine swap,
and just say i have tuned the car, and since its older than 10 years, i wont have to
pay taxes on the aditional horsepowers.. rules over here.

"THEM" reffering to Goverment owned wannabe police for ruining any fun when it comes to
having cars, modifying them, etc etc. Very very very strict. So i will have to show my car.

And if they would find the rocker cover suspicious because of the "NEO VVL",
i guess i could just fit the DE cover, i guess it will fit?



However, if everything is okay to get it street legal over here, i would defo get one.


So, it should be just straight forward swapping the engine.

The NEO VVL would most likely have everything.
Transmission
Clutch
Intake
And Exhaust manifold.


The VE and DE is the same engines with different heads if im right?
so that means that my existing exhaust frontpipe will fit
the SRVE manifold? or my SRDE manifold will mount
right on the SRVE? my CV axles on my current gear box will fit the gearbox on the VE?

So the only thing to worry about is the ECU which i also will get my hands on.
So when i have the ECU, after the engine is in, is it just as simple as plugging the new ECU to the socket and then im ready?

Will i have to wire and customize anything? i remember i heard about that somewhere..


Oh, and yeah, since its a 40hp increase, wouldnt i have to get a different exhaust system?

Right now im using stock which is around 2  -  2.25 inches inlet is that right ?
(P11 GT 97. 150hp/110kw)

I remember to read somewhere that 2.25 was minimum for 150Hp so at least 2.5 inches for the 190hp.

Could i still use my existing exhaust? how would it impact my performance and engine?



Anything else i should know about,

And are this engine by a chance Tüv Approved?
Im afraid that if it isnt, i wont get it road legal, but still thinking about
that rocker cover trick, and lie about the existing engine are tuned.

But i also think the engine might be tuv approved because ive heard different
cars in EU runs with these engines originally.
Thing is, the VE comes straight off a primera, so they cant complain when it still in a primera lol.
Question is, if the PRIMERA in EU have to be approved holding a VE, since VE was only in Japanese and Australian primeras?




So is it bolt on for me?

Put the engine in, connect all the cables and hoses, fit my current exhaust to the VE
manifold, fit the CV axles, plug the new ECU, then start engine?

211hp here with a 2.25". A quality build makes more difference than diameter.

Oh and just to add, our brand new N1 build stroked to a 2.0 Litre idles perfect, and only too 1/2 tank from Edinburgh to Durham and Back. That included some 8200RPM Wagon Overtakes.....Unmapped! And that exceeds the 200BHP mark, as it has a lot more power than a stock SR20VE with N1 cams.

So i cant use either the VE ecu or my current DE ecu and get the 190hp?
so i really need to get a remapped ecu? there is no other way to do it?
sounds like a hassele for me. i have nowhere to get any remap. was thinking of buying off ebay.

unfortunately its a pain in the butt
