Guest chiefvinso Posted June 22, 2005 Share Posted June 22, 2005 So its a good thing then? I have never heard of coild packs. So can you run whatever plugs you want under these packs? Link to comment Share on other sites More sharing options...
Guest Terry S Posted June 22, 2005 Share Posted June 22, 2005 not any old plug. Stick with whats been recommended here Link to comment Share on other sites More sharing options...
Guest chiefvinso Posted June 22, 2005 Share Posted June 22, 2005 Soz I did mean what plugs were mentioned here. Just a techy question now - what is the benefit of a coil pack over leads and why would the vvti witch over to leads? Link to comment Share on other sites More sharing options...
Nic Posted June 22, 2005 Share Posted June 22, 2005 Terry roughly what sort of price are they?? Gonna get some 24's from the US for about £40/45. James, I have similar sort of spec to you and use S45i's which is the same heat range as the 27's. If anyone else wants Desno Iridium plugs, give me a shout as I can get them for a good price here.

Alex Posted June 22, 2005 Share Posted June 22, 2005 Soz I did mean what plugs were mentioned here. Just a techy question now - what is the benefit of a coil pack over leads and why would the vvti witch over to leads? The VVTi didn't switch to leads per say... What did happen though is that instead of the dual coil packs they have a single on plug coil which fires two plugs at the same time (wasted spark) but due to timing fires another plug further down the engine....the only way to reach is a short lead. So on a VVTi the coil pack on cylinder 2 fires cylinder 5's plug as well. The coil pack on cylinder 6 fires no.1 too...the pack on plug 4 fires plug 3. This is all down to the wasted spark (VVTi only) system. And the order of which pack is connected to which plugs is down to the firing order of the cylinders. Basically there is a coil on the EVEN plugs 2,4,6 and a short lead running to 5,3,1. Per combustion cycle (all 4 strokes) the coil double fires both cylinders. There are only 3 ignition lines on a VVTi compared to 6 on a normal Supra with dual Coil Packs. Link to comment Share on other sites More sharing options...

The VVTi is wasted spark , and has 3 x Coil packs ( on plug) which fire 3 x HT leads. Link to comment Share on other sites More sharing options...

I'm still have my revs bounce but that's something else now. Link to comment Share on other sites More sharing options...
