feedback wanted: a 20v coilpack adapter as a product to sell

[Sam-Q]

hi guys I have just finished machining something up that was suprisingly hard to do. It's a coilpack adapter plate that bolts to the valley of the 20v head in 3 places and then lets either the yaris/late echo or the early echo coilpacks to be fitted. If there is any interest I might get some more made up with a C&C mill. They are a full bolt on job and fit exactly right.

I would like to hear back from people if they think such a product would be wanted by anyone if the price was ok, or if anyone had an suggestions.

Apologies for the crap photos. The yaris coil is on the left and the early echo coil is on the right. They are in the actual position where they are used with this plate.






admins, please let me know if I breaking some rules here.

Would it be possible to laser cut instead? That could well make it bucketloads cheaper, as machining time would all but disappear.

I will look into it, thanks for the tip

He Sam, is there a performance improvement with this over the stock dizzy I have, and would it fit in a fwd setup?

[Adsie]

Yeah I would be interested pending price of course. Was looking for a way to hold them down as mine seem to move around heaps and get pushed up.

i thought that coil on plug isn't ideal because of the heat the coil pack gets make them wear much quicker. that's why nissans always have coil pack problems. why not just stick with 4 externally mounted?

quade: this will suit any 20v, you just unbolt the 3 clips that hold the original leads in and it uses those mountings instead. Coilpacks would not provide any power gain providing your leads, cap band rotor button are all brand new. After that it would be going downhill while the only servicable component with the coilpacks is the spark plug itself. The way I see it is bought these yaris coilpacks for $140 for all for (thanks to brendon/driftpig) and a new set of spark plug leads is around $100 and thats not even going into the imported dizzy cap if I had one.

Hokey: good point but this is once again a case of nissan = stupid engineering. There is no doubt that coilpacks get warm and have to shed the heat, have a look at the central cover of a 1JZ and you will see toyotas classy way of doing this. Nissan on the other hand had them buried right in the gap in the engine and also had a cover over the top that allowed for crap airflow. All modern engines that I know of are slowly going to coilpacks. I hear that with the Yaris coilpacks you can fit a silvertop cover back over the top, this will hurt the coilpacks for sure in the long run due to heat stress.

haha stupid nissans. i knew you'd already thought of this sam.

Cheers

hehhehee, thanks

although one person I have spoken to has already accepted the trade-off and will run a cover over his coils. I gues either way it would still take a long time before anything would happen.

fk yeah where do i pay??!! make an alloy cover for them and ill take one of them aswell!!
