Av8er Posted December 28, 2012 Share Posted December 28, 2012 Could someone please explain to me in a dumbed down manner, the differences between DE and HR engines. I've seen them referenced everywhere, but nothing to explain what they are. I tried the search tool and google but no luck... Quote Link to comment Share on other sites More sharing options...
Wasso Posted December 28, 2012 Share Posted December 28, 2012 Dumbed down version = HR has more power than DE. Quote Link to comment Share on other sites More sharing options...
ATTAK Z Posted December 28, 2012 Share Posted December 28, 2012 Early cars were DE engines with dipstick at the side of the engine. Same DE engine went into what are known as upreved cars with a bit more power but lower on torque. In 2007 the engine was changed to the HR with the dipstick at the front of the engine. This is a totally different unit and it necessitated a body work modification to fit it in (bonnet bulge). Again this resulted in more power and a bit less torque, but you wouldn't really be able to tell the difference performance wise. On the way, the GT4 got the uprev DE engine in 2005 before it became standard in 2006. Quote Link to comment Share on other sites More sharing options...
Av8er Posted December 28, 2012 Author Share Posted December 28, 2012 So very little difference really? Quote Link to comment Share on other sites More sharing options...
Bockaaarck Posted December 28, 2012 Share Posted December 28, 2012 (edited) So very little difference really? Six of one, half a dozen of the other Not a huge amount of difference between them other than what the guys have already indicated. Would you feel the difference? Possibly, I run a 2003 JDM with the 276 bhp (with a plenum spacer, Milltek exhaust and Y-Pipe modification and UpRev) and it feels plenty fast enough to me Edited December 28, 2012 by Bockaaarck Quote Link to comment Share on other sites More sharing options...

I thought the HR was 300bhp? happy to be corrected as i'm still learning about these Quote Link to comment Share on other sites More sharing options...

I thought I read there is more weight in the later cars that's negates the extra power, is that right? Quote Link to comment Share on other sites More sharing options...
Dblock Posted December 29, 2012 Share Posted December 29, 2012 Yeah more weight but hardly it wasnt THAT much. A good HR will still have a good few Hp more than a fully n/a and Upreved DE. Plus you get the dual intakes, better/newer/more powerful engine, better interior a better base to tune in n/a or turbo/supercharge if you want. The final model is always more polished. If you have the HR its a great car. If you don't a DE is still awesome. Quote Link to comment Share on other sites More sharing options...
agentdarkshadow Posted January 20, 2013 Share Posted January 20, 2013 So safe to say my 2002 fair lady import will be the DE engine then? Quote Link to comment Share on other sites More sharing options...
spursmaddave Posted January 20, 2013 Share Posted January 20, 2013 So safe to say my 2002 fair lady import will be the DE engine then? 1000% Unless it was owned by Marty McFly £ Quote Link to comment Share on other sites More sharing options...
