Did they or did they not have the Variable valve timing ?

 

Did the power drop to 280 for the manual in the final years?

 

Any help would be appreciated, would rather have the extra 20bhp.

 

So, I would say the 'myth' about later models loosing VVT is not quite true ;)

 

 

It's written in Nissan literature though.

maybe it was only the US market that lost it?

 

They only got the Z32 until 96.

I don't think so. Unless the engine was changed in 1999 with less than 1,000km on it.

 

It has the later style injectors too and from what I can see, the engine is 100% geniune, never been out ever.

 

So, I would say the 'myth' about later models loosing VVT is not quite true ;)

 

how do you know it has VVT?

 

What was your method of prooving it? Bear in mind if its from conzult, you have a chipped ecu - which in the interest of supporting all cars with a 16bit ecu the chip's map would have vvt even if in your car it didnt use it.

280 with auto box and 300 with manual box

280 with auto box and 300 with manual box

 

not strictly true.

 

USDM Manual = 300BHP

USDM Auto = 280BHP

JDM Manual = 280BHP

JDM Auto = 280BHP

UK Manual = 278ps (so 280bhp)

UK Auto = 263ps (265 ish then)

 

They were the original quoted figures from nissan.

 

However as speculated time and time again, was it really all the same and the manual engine produced 300bhp and the auto 280bhp?

Or was this a minimum garanteed power on the fuel available? (quite possible IMHO)

 

Was the 300zx indeed more powerfull than originally quoted due to the gentlemans agreement? (I dont think so personally)

(This we know to be the case with the RB26DETT engined GTR, 280BHP my foot, standard cars with several years are often RR'd at nearer the 320bhp mark!)

 

End of the day, with all mechanical things some are better than others, you can have two seemingly identical cars yet one is quicker than the other... I had a made who had two rover 214's, both on the same plate both identical (according to rover) yet the first one he had was CONSIDERABLY quicker! Noticable to even a passenger.

 

Most quoted MFR figures for power output are a minimum, or normally conservative, to cover them selves if they do get a bad one. Torque is now measured over a "range", as an average over say 1500rpm to 3800rpm or somthing daft this means you can give a lower "wolly" figure - MFR cant be held responsible if its not quite up to the mark etc

 

Max speed is another example, cars that will do 115 on the book will more than likely drag them selves around to 125-130 given enough straight!

What did you look for to check for VVT, the sensors on the back of the cams ?

 

Yep! And on doing a conZult switching them on/off manually changes idle RPM.

 

Mike Feeney confirmed from the chassis number that indeed it was manufactured in May 1998, so it's only just gone 10 LOL awwwwwwwwww bless :)
