Alex Posted January 5, 2003 Share Posted January 5, 2003 The Export spec was more powerful, which allows you to lengthen the gearing without losing acceleration. Longer gearing reduces emmissions cause you don't stress the engine as much at a given speed. MPG is also improved. Cuth if you mean how can a j-spec hit 162 and a uk go only to 155, you've mis-understood. The uk is limited to 155 - take the limiter off and it is geared to 204mph. The j-spec comes limited to 112mph take the limiter off and it will be geared to 196mph. Quote Link to comment Share on other sites More sharing options...
cuth Posted January 5, 2003 Share Posted January 5, 2003 Alex and eyefi - Thanks for clearing that up. However it is a bit disappointing to hear that I'm never going to hit 200 in my J-Spec....boohoo! Quote Link to comment Share on other sites More sharing options...

It will, once you raise the rev limit when you've modified your block and head to handle more power and revs, oh and fitted an aftermarket ECU!

FaithStalker Posted January 6, 2003 Share Posted January 6, 2003 try the M25 - you'll have pictures oif you speed at certain ponts around, then you can post these on the Board to prove you made it to 200, plus you'll have nothing better to do being banned for 5 years Plus if your going against a UK spec - you'd "leave it standing" for the first few GATSO's :flame Dev :flame Dev Quote Link to comment Share on other sites More sharing options...

Matt C Posted January 11, 2003 Share Posted January 11, 2003 Earlier in the thread somebody said 85mph in 6th was 3000rpm. Wasn't sure if it was a J-Spec or a UK but mines a UK and at 3000rpm I'm getting 90mph. Speedo could be a little out I guess...??? Somebody else with a UK car wanna give it a go....??

Matt C Posted January 12, 2003 Share Posted January 12, 2003 Another theory.....I assume it works via RPM in top gear, maybe the speedo is that far out at that speed that your not actually reaching the limiter but according to the speedo.....you past it ages ago. Only a guess..... Quote Link to comment Share on other sites More sharing options...
Steve W Posted January 12, 2003 Share Posted January 12, 2003 Matt, as far as I know it's a SPEED thingy.... Pete's 'box-of-tricks' takes the SPEED signal and does several things to it... Converts from km-miles - by altering number of pulses (5/8ths or 8/5ths ? ?). ( you can then send either of the 2 signals to the speedo or the odometer - your choice !) AND it grabs the SAME signal - which also gets sent to the ECU - and 'CAPS' it to ~100/110 mph...THAT IS limits the pulses to an amount = that speed. The ECU then thinks your 'sticking' to that speed when in fact . . . . . . . . .! ! ! !:flame Dev Basically you feed ONE wire IN to Pete's box and have 3 wires out AS IS. RE-RATIO-ED. CAPPED. Mine WAS limited to ~ 120 (?), snipped the wire to the ECU, fed it the 'CAPPED' wire = WAHOOOOOOO ! [i [b]THINK[/b] ! ] FatS. Quote Link to comment Share on other sites More sharing options...
Matt C Posted January 12, 2003 Share Posted January 12, 2003 So the UK's top end limiter works this way too then I assume...?? There I go again.....'UK'. Quote Link to comment Share on other sites More sharing options...
Steve W Posted January 12, 2003 Share Posted January 12, 2003 Now THAT I don't know........MATTSIE !( ) (don't get involved with UK rubbish........ggrrr.....rant....dribble.....) You may be right, UK and Jap limiters may work different ways, 'cos, WE can't knock the limiter out by pullin' the TRAC fuse ! (can't seem to knock the TRAC out by pullin' it either !) GOD, this thread is far too tecnybubble for the likes of me...... derr...emmm....oh yer....FatS. Quote Link to comment Share on other sites More sharing options...
Matt C Posted January 12, 2003 Share Posted January 12, 2003 You can't turn the TRAC off in the Jap car...?? The button is there though ain't it. Now I'm confused!?!?!? My TRAC button seems to work, tested it just the other day by doing somewhat of a spirited start from a set of light with it turned off. Tyres smoked more than a Rasta sat on the beach in Jamaica! Needless to say, won't be testing it again......once is enough. Quote Link to comment Share on other sites More sharing options...
Steve W Posted January 12, 2003 Share Posted January 12, 2003 NAH, if I turn it off it STILL seems to interrupt me' 'fun' - not that it's easy to spin the wheels on the auto' anyway ! ! AND, with it ON, it seems to have a delay of ~ 1 second...? ie. when I had my 'likkle' accident, the wheels spun, it stepped out hard one way, I 'sort of' corrected, then the TRAC cut in and made it pendulum back the other way ! ! ? I NOW don't spin the wheels in the wet AT ALL..... I drive like a SOPPY-SOUTHERNER until the sun shines again Quote Link to comment Share on other sites More sharing options...
Matt C Posted January 12, 2003 Share Posted January 12, 2003 I drive all nice usually in the wet, just had to test though. In the order of science. Quote Link to comment Share on other sites More sharing options...

From my experience at 10 of the Best, I think I can say the following is a pretty accurate account of what happens (UK spec auto); With the TRAC fuse in, you keep accelerating until the ECU thinks that the combination of revs and gear are giving more than a TRUE 155mph, then it activates the TRAC butterfly (bad boy!). At TOTB, I got up to about 182 on the clock, but the best official timing was 157 or 158. I think one of the other Supras at the Nissan 200 TOTB2 can also substantiate this.

If yours doesn't work then unplug the butterfly... Can't fail! Gaz, All the reviews I've read say the UK's limited to 155... Even my original Top Gear video review says that.
