Finally my 1st (water cooled) turbo build
So I'm finally putting together my turbo and need some advice...here is what I have so far:
car- Ugly as hell, 1995, 1.8- Long block rebuild in process
Megasquirt 2
GT 2560
ID 1000's
ARTech SGDP to 3" exhaust
Turbo Sport BOV
sprearco IC (forget the size) ill get to that later
FM oil filter relocate
manly rods
Toyota cops
949 twin disc
15x9's
empty bank account
Searching for 225-250 whp. Is this a realistic goal?
Question of the night..Do I need to run a fuel pump/ regulator set up? from the FAQ Archive, It looks like I do not. Shooting for well under 300 hp and on a stand alone.
I have a few beer bottles surrounding me and a tube of skin thickener, so let the flaming begin...

Building my cops harness now.. Following the sticky, I don't understand where the 10,000uf cap goes. Or better yet, I don't understand the directions. I have a megasquirt so, I do not need the capacitors?
EDIT: So it looks like the capacitors provide the full charge to the coils. Understood. Wouldn't it then be helpful to have a capacitor on each of the 12v leading to the coils and not just 1 on the main 12v source?
on a 1.8 (1995.5) since I have two plugs at the coils, am I going to actually have two separate harnesses, one for 1&4 and another for 2&3 ?
Are you guys just cutting off the connectors, or installing a male plug to go the the factory harness? Anyone have a plug part # ? the one in the write up seems to be just to the cop itself.

A quick pay-pal query, says that my budget turbo build is at about 5k and counting. Does someone have a free 6 speed lying around? maybe a coolant re route? Ohmy gawd, this is nuts.

I started my wire harness for my ls2 coils, and have run into some confusion.
going off of the COPS write up, a Toyota coil is wired like:
1. Ground
2. Trigger
3. Tach
4. +12 V
But then the Ls diagram shows:
A- Coil GND
B- Ignition Low Noise Ground
C- Ignition Digital Signal
D- +12 V
could someone please help me understand these Ls coil labels please? Does the diagram for the wire harness (which is written for the Toyota part) also apply to the ls coils?
Thanks,
Ryan

No, not entirely. The LS coils have no tach out pin. They only need three things, a trigger, 12V, and ground.
Tie both A and B together, and wire them as grounds the exact same way you would toyota coils. That extra ground is for misfire detection or something similar a megasquirt can't use. Everything else is the same, wire them in batch as the trigger is the same for LS2/toyota cops. You won't have a tach out, which I think is fine on your car. I believe it's driven off the ECU on 1.8s, and the megasquirt should already be wired and configured to drive your tach.
