Dynamic Turtle Posted August 20, 2012 Share Posted August 20, 2012 Is the "upgrade" noticeable? I understand it has a slightly smoother gearbox as well as a 13% increase power (though it's probably not a "linear" factor). Just mulling a thought Quote Link to comment Share on other sites More sharing options...
Will370z Posted August 20, 2012 Share Posted August 20, 2012 Best person to comment is ebized as he has had all 3 350 engine variants and now the 370z The later engines had more power obviously but some say the early cars had more torque. I drove around 5-6 zeds with different engines in wales last year. The difference was noticable between all the cars but oddly it had little to do with the engine. We put it down to the ecu adapting to the drivers style, those zeds that were pushed hard by their owners flew while those whose owners didnt push their cars were noticeably more sluggish. Not sure if this is a valid conclusion but it was certainly a trend. Quote Link to comment Share on other sites More sharing options...

I believe Ebized only had a 276 & a 296 then the 370z I on the other hand went from 276 to 436 Both your Zeds go/went well Will Quote Link to comment Share on other sites More sharing options...
Will370z Posted August 20, 2012 Share Posted August 20, 2012 Ah my bad i thought he had owned all 3 variations but i believe you are correct. Quote Link to comment Share on other sites More sharing options...

Boss Hog Posted August 20, 2012 Share Posted August 20, 2012 Only owned a 313, but test drove them all. I found that the 313 felt noticeably better around 5-6k revs, and opn more than one motor. Surely dyno power maps would be a good place to look though. Aidan Quote Link to comment Share on other sites More sharing options...
Darren-B Posted August 20, 2012 Share Posted August 20, 2012 To be fair it`s not all about numbers, it`s how you drive the car & how well the map suits your driving style. If you love the revs get a 313 with the higher rev limit out the box & a bit more top end power, if your one to use the whole rev range stick with a 276 & get an UPREV. I`ve driven numerous of all 3 variants, modded & un modded including numerous 370`z modded & un modded. Unless they are boosted or running nitrous theres bugger all difference on the road. Have a feeling I may have just opened a big can or worms Quote Link to comment Share on other sites More sharing options...

Darren-B Posted August 21, 2012 Share Posted August 21, 2012 313 1000x better than a 276 had both But are you talking about just the engine or summarising the engine, body & interior upgrades as a package? Quote Link to comment Share on other sites More sharing options...
Wasso Posted August 22, 2012 Share Posted August 22, 2012 I was having a chat recently with other Zedders. Put all 3 variants in a line, NA modded or not and you'll be lucky to see a car length between each car to 60mph. BUT! Put a decent driver in a 276 and a noob in a 313 and you'll see a marginal difference. Unless (as Darren has said) you go FI or NOS it's more about what YOU want the car to look and feel like. If you want different interior them either choose the 313 or 276, and I wouldn't bother with the REVUP 296, I've got one and they're a nuisance to FI, especially on the second hand market. Actually saying that I guess the 313 can be a pest too. Stick with the 276 Quote Link to comment Share on other sites More sharing options...
