okay so I have a 1999 spyder gs with the 4g64 N/t conversion. there are 2 good write ups Ive read over several times so that I can proceed for the turbo swap.

-car starts but dies will actually run for about 5-15 seconds but sounds like misfiring. %100 new igniton system with NGK cold plugs properly gapped, NGK plugs and new OEM coil pack.
from what I understand, you can turbo this 4g64 single cam engine as is assuming you have no other issues with the engine. you can leave the sohc head in place along with the n/t throttle body and ECU, assuming you have a way to tune or adjust the fuel and generic knock sensor control, overall I thought it would be easier to work with what I had which is a 95 EPROM ECU which worked fully from my last car about a year or so ago, before I parted out. kept the ECU in the house in a dresser the whole time. inspected it before and after this no start issue and found no leaking compacitors, disconnected pins or arcing marks.
-followed the rewire guide %100 and actually trying to install the turbo TB and ecu before the engine gets turbod to work out any electrical issues before actual swap, which is whats happening. So far I added in a 190 fuel pump correctly bypassed the relay and am getting fuel , voltage pulses from the injector plugs, but car acts like it is misfiring or out of time.
-stock 275 injectors in, and bigger fuel pump with factory turbo fuel regulator installed for a while with the n/t ecu installed with no problems, swapped back to n/t ecu in after turbo ecu install and engine starts, WITH the TURBO throttle body and sensors in place. TB is new and IAC fully checks out. TPS is questionable.
debating between the TPS and turbo ECU. sending it out tomorrow. any possible suggestions on what I can check? the guide says I should be fine but I don't know what to check otherwise.
