Tommyg_5 Posted November 2, 2022 Share Posted November 2, 2022 I have been working out how far to go with my NA T conversion. Whifbitz sell a r35 coil on plug conversion kit, which seems to add a lot more control when tuning. So does supra VWorld in Aus. Anyway Supra V requires you to buy https://www.supravworld.com/product-page/dual-cam-crank-trigger-kit-2jz-ge-non-vvti-only Whereas Paul from whifbitz explained to me no changes are required to cam sensor etc. Can someone explain to me what I'm not understanding! Why does one kit need it and one not? Help a dummy out! Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted November 2, 2022 Share Posted November 2, 2022 Both coil kits offer the same thing in terms of performance. If you are running a distributor, you can convert to coil over plugs and use the distributor to trigger when the coils fire as the dizzy technically provides a crank/cam signal to the ECU. The trigger kit offered on Supra V will allow you to delete the distributor as it references the cam/crank signals through its dedicated crank trigger and cam trigger. You don't have to run the trigger kit to run the R35 coils, but the trigger kit will allow for more stable crank/cam trigger signals to the ECU, especially with higher RPM and more power, as the stock distributor can have issues provided a clean signal at these sorts of levels. My advice to you is that if you are planning on running R35 coils, do not waste your time with unmarked aftermarket coils. I must have replaced over 15 sets of these knock off coils due to issues with misfire and coil degredation. Do yourself a favour and buy a coil kit that uses genuine hitachi oem R35 coils. It costs more but will save you a lot of headache. Dont skimp out basically. 2 Quote Link to comment Share on other sites More sharing options...
Tommyg_5 Posted November 3, 2022 Author Share Posted November 3, 2022 Thanks Mike, that's cleared it up! One of the main reasons was to ditch the distributor as its right in the way! Looking at your build, does the vvti head still use a distributor? Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted November 3, 2022 Share Posted November 3, 2022 No it does not not, it uses cam sensor like a TT. Normally we pair this with a ge VVti oil pump or TT oil pump that will allow us to run a crank sensor. 1 Quote Link to comment Share on other sites More sharing options...
