Mate you biggest problem is that your fuelling is going to really really lean if you have never had it setup before!!!!
Your 20 year old KJet fuelling system will not self adjust the fuelling for anywhere near 18psi if at all!!

Set the timing to 12DBTDC and your boost as low as you can and drive it to a tuners ASAP or you WILL have a meltdown and all your hard work will be wasted!
