witstu Posted November 21, 2009 Share Posted November 21, 2009 How does the GT4 engine get its few extra BHP compared to the standard early Zeds? Is it easily achieved for a non GT4 owner? or is it a different engine? Thanks for any replies. Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted November 21, 2009 Share Posted November 21, 2009 i think the GT4 engine is what turned into the 2006 facelift engine. Quote Link to comment Share on other sites More sharing options...
3FIDDYZ Posted November 21, 2009 Share Posted November 21, 2009 296 as opposed to 276, known as a revup Quote Link to comment Share on other sites More sharing options...

Thanks for any replies. not sure if you can swap engines, but you could try a re-map if you want to achieve the 296 Quote Link to comment Share on other sites More sharing options...
rich5259 Posted November 22, 2009 Share Posted November 22, 2009 get the NISMO chip, Ian got 301 BHP with that Quote Link to comment Share on other sites More sharing options...
3FIDDYZ Posted November 22, 2009 Share Posted November 22, 2009 If you have a look through for info on the Uprev from Abbey, you will see some comparisons between the engines after mapping. With mods you should see about 300 from a 276 car (and loads more torque!) it may be an easier route than the nismo chip as thats really for import cars not UK ones! It seems from the mapping that 276's can see more % power increase than the revup's as the revup engine seems to be on the limit. Just search for uprev and you will see some maps that will explain more. Quote Link to comment Share on other sites More sharing options...
Chris`I Posted November 22, 2009 Share Posted November 22, 2009 As the others have said, the easiest way to up the power on the 276 is to get a remap. It will give you slightly more power than the 296 and also more low down grunt than it. To truely change the 276 into a 296 you are looking at quite a lot of work, inc cams. I think they also added VVT to the exhaust valves, which I am not sure you can retrofit to the 276. As said, remap is the best option.

CaptainSensible Posted November 22, 2009 Share Posted November 22, 2009 Taken from here: http://motortorque.askaprice.com/review ... n-z350.asp At the heart of the 350Z lies a remarkable engine: the award-winning 3.5-litre V6 from Nissan´s ´VQ´ family. Voted one of the world´s best engines for a record 11 years in a row by influential American journal Ward´s Auto World magazine, the VQ engine is acclaimed across the world for its abundant power and smooth delivery. But Nissan is not a company to rest on its laurels: the all-alloy, 24-valve twin cam unit, which was extensively redesigned for its role in the 350Z, has been further enhanced for the latest Z-car. As befits a pure sports car, the changes target performance by enhancing the unit´s free-revving ability. First seen in the limited edition 35th Anniversary edition, launched earlier this year, the engine revisions raise power from 280PS to 300PS and move the rev limit from 6,600 rpm to a heady 7,000 rpm. Peak power is now developed at 6,400 rpm, some 200 rpm higher than previously. The improvements have been achieved by traditional methods. In other words, the changes have been implemented not by simply ´chipping´ the engine´s electronic brain but by careful re-engineering of a number of key components. With the aim of raising the rev limit and boosting power, the major changes allow the engine to breath more freely thanks to a redesigned intake duct. Along with new pistons and a revised camshaft profile, the intake manifold has also been shortened and widened. The timing chain and oil pump have been redesigned and electronic exhaust valve timing control has been adopted. A number of other components have been lightened and stiffened to reduce internal friction and to enable them to withstand higher engine speeds. As well as raising power output and rev limits, the engine is now fully compliant with Euro IV emission regulations. The changes have brought about a slight reduction in peak torque, which has fallen from 363Nm to 353Nm at 4,800 rpm. However the revised torque curve is far flatter than before and provides greater torque reserves at higher rpm. Torque delivery in the original 350Z fell off comparatively steeply once that 4,800 rpm peak had been reached. In the latest evolution the torque curve remains more linear as engine speeds rise: at 6,000 rpm, for example, the new engine delivers a full 20 Nm more torque than its predecessor could achieve. What the changes mean in practice is simple: sharper acceleration through the gears. With the rev limit raised to 7,000 rpm, for example, maximum speed in third gear increases from 142 km/h to 150 km/h (88 mph to 93 mph). The benchmark 0-100 km/h (0-62 mph) figure has been cut from 5.9 seconds to 5.8 seconds (6.4 to 6.3 for the Roadster). Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted November 23, 2009 Share Posted November 23, 2009 This is a good comparison between the 3 350z motors all 3 have been UPREV tuned PURPLE 276bhp motor DARK GREEN 296bhp motor LIGHT GREEN 313 bhp motor For a road car I dont think you can beat a well tuned 276bhp far more mid range torque.
