I understand that they have inbuilt ignitors in the coilpacks, and have the signal from the CAS to fire, BUT if you were to use the s1 loom using the EXTERNAL IGNITOR with the s1 coils, will I be able to do this? I can sell the coilpacks, but I'm I want to see if it can be done, the coils are less than 2000km old, it's cheaper If I can go this way and to be honest in my opinion integrated ignitors on coilpacks is a more un reliable set up as it's introducing further heat to a area which is prone to cracking ect ect, it's not so much about $$ but more so using what I have and reliability

the connection wont fit. but if you get the ignitor loom, and coil loom you can cut and wire it in manually. a good tuner electrician should be able to do this without any issues.

but you are better off trying to find someone who would be keen to swap the s1 coils for a s2 set.

by the time you wire it all up its going to be better to just sell the coil packs and buy a proper series 2 set.

Cheers guys, I'm not to bad with electrical, I just wasn't sure if the ecu wouldn't read it or if it was throwing out different voltages ect ect, so in saying that I should be able to do it,

Thanks alot, appreciate the help

The ECU sends the same signals out regardless of which coils/igniters are at the other end of the loom. It's just that the wires run direct from the ECU to the coils in the S2 case and have to stop off at the igniter in the S1 case. In the same way, the various igniters don't much care which ECU is telling them to fire, and they also don't much care which coil they're then firing (assuming separate coil and igniter), unless the coil also has an igniter, which is not so good.

      Nah. Was just wondering if you were having a small stroke or if there was some slur/gaf/inside joke that I wasn't aware of.

      That was a fark up, it's Salamanca Place I was thinking of. And now I'm curious as to what potential slur/gaf I have caused with Salamander Road, ha ha!

      Actually everyone on the roads was really well behaved. The only person that did any minor tailgating was a local hoon in a Turbo Focus. Unfortunately we weren't going the same way so there was no grand initial D touge battle. Lots of people pulled over and let me through. The amount of "Hey man nice car, omg skyline, nice 34 man woo" was suprising. Like really suprising. Like almost annoying. My partner was obviously surprised, she'd never seen anyone in the real world point out the car/like the car/want to chat about the car before, so to have like 3 people per day mention it was notable, I could finally say SEE? SOMEONE THINKS THEY'RE COOL. Everyone was also pretty suprised about the weather. Every day was dry and about ~13-14C. Mount Wellington had a sign that said they close the gates at 9pm and I was heading up there at about ~7:30. It was VERY apparent that conditions were getting significantly worse by the minute on the way up and down. The road on the mountain was terrible though, it's no driving road. I have various suspension related questions now. Luckily it was only about 20 minutes from where we were staying to the top of the mountain as said Google maps. We only had the 2 nights in Hobart. We went to the Farm Gate Market though which was really good - And went down to the Hastings Thermal springs/caves down there during the day. I'd definitely be up for going back again, so luckily there's a few more sights yet to see. Didn't get to do the west coast/queenstown/cradle mountain so this was supposed to be a 'scouting' trip anyway of sorts if I were to one day do/take part in/organize a more car-focused trip. As for the boat, it wasn't bad. Well it was bad, but not in the way you're thinking. We did the night trip which leaves at 6:45 (though you have to be there ~2 hours earlier) and arrives the next morning at about 6am. There is nothing to do on the ship. If you plan accordingly and bring a book/tablet/show to watch/charger you can just chill out, take some Travacalm and just sleep through it. The food there is an extremely basic buffet that costs $32 a plate, or $14 for a $3 pizza. The way back we had a travel kettle and a few different types of cup noodles and made our own tea/coffee in the room. This was a far superior way to do it. At the very least book one of the rooms with beds. I guess as we were in the off season we didn't have room mates. You get an option for rooms with 4 beds (2x bunks) or a room with just the two bottom beds. There's also some option for a deluxe queen bed but it's much pricer. We've been on sleeper trains in Asia before so we figured this is similar (and it was)

      Was that deliberate?

      You just gotta be really, really, really clear and decisive with what you want your end product to be. 99% of people who want this conversion aren't "I want to run a 295 front tyre!" so they don't really need the widebody. They just want the OEM body to look a little less dumpy, so bonnet, bar, skirts job done with some camber, stretch, slam. It's when you want that, but then decide to pivot later you get big problems. See also if you're willing to get an all in one fibreglass bar, and you're willing to accept fibreglass problems like cracking the entire item on a driveway, instead of just a piece attached to the bottom, etc etc etc. Decide this all before buyin'.
