Best Performance Engine for Nissan B12

[FBB]

Hi Everyone<br />
<br />
Alot of people suggested me for QG18DE, but my interest always make me stop at GA16DE or QG16DE as both are 1600cc and affordable in the aspect of Fuel at least. In our Kabli Market we found GA15DE, QG15DE and QG18DE normally and GA16DE is almost not available as well as QG16DE. I dont know why engine people are not bringing these 16 series in Pakistan.<br />
Yesterday i found GA16DE with one guy full harness to harness and complete with Gear box but unfortunately that engine does not have its ECU. The engine is brought from Australia and that guy deals in European Engines instead of Japanese Engines. I want to know will GA15DE (Stock in my Car) ECU either works with GA16DE as GA16DE is VTEC and can we find aftermarket parts of GA16DE ?? @star2 @dani_kk @ser_gtr @Isb_Cap can you guys help?

GA16DE And VTEC??? You Are Literally Mixing It Up With D15b HONDA Motor.... VTEC Is Valve Timing Tech By HONDA..Not By NISSAN

BTW GA Series DOnt have any special valve timing feauture......

Find GA15 As JDM And Euro Models May Have Diff ..

[FBB]

@ser_gtr yes i know about it but i am not mixing the technology. VTEC is by HONDA and VVTI is by Toyota and VTC is by Nissan usually known as NVTC. But behind all of them the concept is same which is available from Nissan in GA16DE, QG16DE, QG18DE and all up models. But not available in below models like 1500cc i.e GA15DE, QG15DE.
Below is the pics of both engines and you can see the difference in them. The black top on thr left side shows its availability.

Those Are Very Rare GA16's Available With NVCS....Usually It Came Without That.....

Actual Nissan Lift Was VVL Which Was Real Deal....! They Sound Extremely WILD And Aggressive

[FBB]

Yep agreed @ser_gtr, but VVL agar mil bhi gya to us pe samajhna yahan k mechanics k bas ki bat nai hai.
Yahan k mechanics ko simple GA15DE ki samaj nai aati to yeh SR series ko khak samjheinge.

What is the average fuel consumption of QG18DE ? And what about QG15DE? @ser_gtr @star2

@qamar bhai
QgG18de is not fuel economical
it averages around 9-10km/L
whereas QG15de gave me around 12-13 on local .It was an excellent engine .
So i'd prefer QG16de Nvct or QG15de simple is better.

Power comes at a cost

And more so if you're forced to replace full braking system and major suspension overhaul

@qamarahmad.awan

Still stuck at the engine decision? GA16/QG16 will be rare to find. Even if you get one, make 200% sure that it is with uncut wiring and original ECU intact, else, it will be deep trouble...

@isbcap @dani_kk thanks for your posts. Yes i am a bit confused because when i made mind to go for QG18DE i had been told that if i ever tried to sale the car it wont be so easy because people dont like this B12 with QG18 .... and alot of other inputs.

Then i wished to get NVCT technology but it is not available in 1500cc engines. And people said that NVCT is useless and its not something like VTEC in HONDA or VVT-i in TOYOTA.

Now what should I do, by the way what you guys say about NVCT ? Is it worthy to get and is it really not the same technology like VTEC or VVT-i ?

Yeah @isbcap true .I made my mind for power so even if it gives me 5km/L ill happily enjoy it plus @qamar bhai firstly honda vtec is something different .As few vtecs are engaging on intake cam shaft and others are on both exhaust cam shaft so thats equal to nissans vvl .Whereas nissan variable cam timing is like vvti and simple vtec in which it alters the timing of engine to + minus 9degree and it engages at aroun 4000rpm and ive felt the engaging effect of nvct its good actually .It's same as vvti and simple vtec.
And trust me if i get Sr16vvl here in pakistan .Vtecs don't even come near that .The technology of racing belongs to Nissan and Toyota so honda is not even in the scene and i'd say go For QG15DE you'd love that engine.

@dani_kk thanks for your always ontime informative input
I will offcourse take the decission very soon as now the GA15 valves are weak enough and the engine is not maintaining its RPM as well. Same is stopping me from long drives, as last sunday i had to visit Islamabad but i was unable because with all the family in the car the car doesnt go more than 90 km/h on CNG and 110 on Petrol and also over heating. So i am just counting the days. Lets Hope to get a successful swap soon.
