    ok ID suggest starting with the ignition upgrades as they will have zero negative effect on a basically stock engine but are almost mandatory once the engines in the more advanced stages of modification to allow it to run correctly under some conditions due to the occasional tendency to run rich or leaner than ideal with the other mods that the stock ignition may or may not be able to tollerate.
    BUT ID STRONGLY SUGGEST YOU BUY a complete system from a single manufacturer or youll constantly have the different manufacturers suggesting the components causing any problem or failures were not due to thier components but to your mismatching or careless installation or parts incompatability, etc. even if that has no basis in facts


    the pump YOU selected will be fine at the hp level your thinking about with a mild EFI set up , but if your thinking about more extensive mods the vette in tank fuel pump info might be helpful,(YOU MIGHT WANT TO AT LEAST LOOK IT OVER)

    basically everything you posted suggests youve done the necessary homework and it should be fine in a mild application

    remember having the correct size fuel lines and return style fuel pressure gauge, is critical to maintaining consistant fuel flow and pressure

    these links might help

    Thanks grumpy,
    I will re-evaluate the walbro fuel pump; it is an inline pump. Especially, if I decide to elevate the performance level of my Zcar; target greater than 300 HP. I did not consider any other pump; maybe a :eek: on my part.
    I diffently agree with uniformity of the next ignition system; Crane has been my choice due to the literature; Summit sent me Crane's Hi-6S ignition controlling unit; and, from my conversations with their TechServ guys, I am considering to purchase Crane's LX-1 coil and Crane's map sensor. I plan to call again for verification regarding these parts and their opperative efficiency with the Z31 ECU or Z32ECU as the next computer upgrade. What do you think of these two considerations; Crane's coil/map sensor and the next computer upgrade? As stated, I really not interested in a standalone. I also am thinking that once the table upgrades are completed that I will have this car tuned via dyno; I have read that this is best for fine tunning.
    I really appreciate your time and input; hope this helps others.

    Enjoying the ride daily
