can i borrow my SAFC and use it to my honda ek4??? could these give extra power on my ek4??? what do i need to do before disconnecting the stuff from gtr???? is it difficult to tune the stuff to my ek4 b16a????thanx
Yes you can, but results would vary depending on your modifications. If it is standard would not recommend as the gains would be doubtful, but if you have done things like extractors, etc - then possibly get some gains.
Look up the US Apex'i site for wiring diagrams for the Honda.
