I've just ordrered a Haltech E6X for the 1JZGTE
(see: http://www.tweakit.net/shop/product_info.php?cPath =&products_id=92),
with a few other goodies. I'm planning on sticking with factory coils and ignition module for starters (no pun intended ). But, as it will be a waste-spark set-up, hopefully pushing in excess of 210rwkw, I'm wondering how long til I need to consider swapping to Haltech's gear (assuming my coils and ignition set-up is in excellent condition, for argument's sake). I've already got Skip's experience to work from - but I'm just wondering if anyone else could add more?
