Hi I have a trouble on my sr20det I don’t have spark and I all ready check every ting my question is: an sr20det s13 is it compatible for my s15 coil pack.

hello, are using s15 coils with s13 wiring ? if you are then you may still have the s13 ignitor in the loom which will need to be removed, the s15 coils have built in ignitor.

Regards Ross

Yes i have the s13 wirring but can you show me an exemple because i am not shure tu onderstand what i need to do exactlie

thank you very mucht for your supplie

Hi There!

Not sure if this is still needed. But.

I installed a S14 SR20 into my S13.

The S13 ignitor doesn't work on the S14/S15 coilpacks.

Best is to get a S14 ignitor and the 2 plugs that goes with it and wire it up to your coils/current harness.

Or better yet, try and source a complete S14/S15 engine wiring harness, as this will resolve your issues.

Here is a pretty solid guide on the swap.
