amstrange1 Posted June 7, 2006 Report Share Posted June 7, 2006 I've tried using the search function to find out, but couldn't get it to work?Anyway, can someone give me a definitive answer to the question - what are the key differences between the 75PS and 100PS versions of the 1.4 16v engine as used in the Lupo/Polo 6N2?

amstrange1 Posted June 7, 2006 Author Report Share Posted June 7, 2006 Reeto Nicki! Cheers for that.I've been geeking on ETKA, it seems that the following have different part numbers between the 75PS and 100PS versions (I've only briefly looked at the engine block and head parts):cylinder headcams (both inlet and exhaust)pistonsThe crank seems to be the same, and I presume the engine block is too. I'm guessing that as the above bits are different the cams in the 100PS may well be lairier, and that there may be a difference in compression ratios? Could do with a bit more detail than what ETKA has to offer really. Quote Link to comment Share on other sites More sharing options...
scoobydoo Posted June 7, 2006 Report Share Posted June 7, 2006 throttle body is larger on the 100 and u have 1000rpm more. Quote Link to comment Share on other sites More sharing options...
Tigz™ Posted June 8, 2006 Report Share Posted June 8, 2006 The pistons, and compression are the same.The only difference is fuelling IMO.As said in the other threads the inlet and throttle body is smaller.The Sport is mapped to run on 98RON unleaded, where the 75hp is mapped on 95RON fuel.The peak power on the Sport is improved yes, but on the bad side of this, the peak torque is up to 128NM @ 4500 rpmThe 75hp engine may be slightly less, but it still makes 126NM but without having to rag it, as its rated at 3500 rpm.The throttle cable of the 75hp engine and the ECU it uses means a remap is only a custom code away, and with the rev limiter raised, and the fuelling sorted I'm confident it would make close to the same sort of power. border="0" class="linked-image" /> border="0" alt="" /> Quote Link to comment Share on other sites More sharing options...
Teflon Posted June 8, 2006 Report Share Posted June 8, 2006 the intake manifold is slightly different too. Quote Link to comment Share on other sites More sharing options...

Any inlet and exhaust differences aren't really important, I'm just trying to establish whether there's any penalty on using the 75PS basic block and head instead of a 100PS version.The pistons are definately a different part number, but that doesn't mean a whole lot, hence me asking the question. What about cams? Does any kind person with access to ELSA fancy looking up the cam profiles? style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" /> Quote Link to comment Share on other sites More sharing options...
loopy_lass Posted June 14, 2006 Report Share Posted June 14, 2006 I found this really useful too, thanks guys. have started looking out for the perfect lupo and have been completely thrown off course because of the confusion in the difference between the sport and the S. So i assume a sport would be a better purchase? style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" /> Quote Link to comment Share on other sites More sharing options...

Petrified Posted June 14, 2006 Report Share Posted June 14, 2006 The Sport is mapped to run on 98RON unleaded, where the 75hp is mapped on 95RON fuel.My sport is mapped for 95RON. hoping that a custom remap will be able to use this to it's advantage style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> and maybe even get rid of that rev limiter.

Petes 16V Sport Posted July 5, 2006 Report Share Posted July 5, 2006 (edited) Found this on EBAY had a little read of the description...... Interesting. Porsche head style="vertical-align:middle" emoid=":confused:" border="0" alt="confused.gif" />6 airbags? I thought the max any arosa/loop had was 4, and 2 of them were an option! Porsche head tuned by audi... or some bog standard vw engineers getting hold of the 75ps version of the 1.4 16v (not the 86ps which is from a polo, incidentally) and going "ahh now for the sport we vill do dis and dis and dis and hey presto there we have 100ps version ja?"

GTIEater16v Posted July 11, 2006 Report Share Posted July 11, 2006 One vital bit is that the 100bhp has multi point injection thats why its 25bhp more. or at least thats what iv been told. style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" /> Quote Link to comment Share on other sites More sharing options...
Petrified Posted July 11, 2006 Report Share Posted July 11, 2006 Currently driving: Lupo 16v Sport running 112bhp on the dyno from only a custom filter!!pretty sure they are both mpi style="vertical-align:middle" emoid=":blink:" border="0" alt="blink.gif" /> out of interest where was your car rolling roaded?
