,i own a rev3 N/A and although its suppose to have slightly more power than the rev 1 and 2 it doesnt seem that much faster infact about the same as my other mates rev 2,s one other lad also has a rev 3 and he says the same ,someone told us its because of the cat and air box and if the cat is removed we will feel the difference compared to the rev 1 and 2s ,is this true ,as how can a car with 20 bhp feel the same as a car with with l20 bhp less ,or is there something else cheers- that's if both engines are still delivering their claimed output, really isn't that much difference. It's not horse power that makes a car fast, it's torque - so the only way to know for sure, is to put both cars on the rollers, and see what the outputs actually are.. - bear in mind that weight will suck power. Heavy items that may or may not be fitted include:
,it was more to finally find out what the differences were really more than anything as we get told and heard that much different things about them ,ive got no intention of making it quicker as i have a bike for me kicks ,but wish id never spent months looking for a low milage rev 3 when really it wouldnt of mattered lol

however the Japanese domestic version of the box has a different final drive.MR2 Rich wrote:How come the 0-60mph is 7.2 for rev1 and 2, and 7.6 for rev3+ with 20 bhp more then?

Unusual for a manufacturer to revise a sports car and make it slower... you sure those 0-60 quotes are accurate? A healthy OEM revision 1/2 NA produced 158bhp. A healthy OEM Rev 3 173bhp. The Rev 4 dropped to 168bhp. However, a Rev1 with a tintop or sunroof, no aircon, no LSD etc will be significantly lighter than a Rev3 T-Bar with all the options ticked.,yes this is a tbar with all the xtras plus stupid big wheels,however after having time to play with the car abit its now a let better infact feels like a different car ,the acis was near enough siezed and vacuum pipes were not in the best condition ,also the map filter looks like it had collapsed inside ,also the dizzy cap wasnt the best either and the fuel filter was well not really a filter anymore ,its now pulling alot harder and smoother ,but still i wouldnt of said there was a great deal of difference between them ,and 7.6 or there abouts sounds about right now to me i think .
