3sge Red Top Swap Question Options

[Jaytwou2]

Hey guys im new to 6gc and i have a few questions...

I have been searching for 2-3 weeks on info on the 3sge Beams Red Top Swap into my ST204 5 speed GT
and from what i understand everything just drops right in place of the 5sfe (correct me if im wrong). My main concern is wiring! Is the
swap plug n play? Or will i need to purchase an engine w/ harnes and ecu?

Reason for the swap: I just picked up my st204 for 650$ With 126k Miles minimal rust and a 8/10 body and completly stock but it has
a snapped timing belt

Reason for choosing 3sge: I want an engine swap that has the power when i need it and the mpg of a N/A engine.

BEAMS sounds like the engine for you. Parts can be difficult to source but not too bad. Give me a little bit and I'll post the wiring up for you.

Edit:


-EA1 plug, pin 17 goes to pin 4. Pin 17 is the bottom left wire, red with a black stripe. Pin 4 is the thick black wire at the top center of the EA1. Pin 17 needs power when pin 4 has it. This gives the BEAMS spark.
-EA1 plug, pins 2 and 12 need to be bridged. Those are ground wires. They need to be spliced together. There should be two wires, parallel to each other. Just bridge them together.
-Clutch start wire- there are 3 vertical plugs next to the ECU. On the body side of the plugs, you have a white (19 pin) plug, light gray (13 pin) plug, and dark gray (17 pin) plug. The clutch start wire is pin 18 on the white plug. Move it to pin 17 on the dark gray plug.
-Cruise control: Contrary to popular belief, no work is necessary for cruise control. It's a standalone system with no wiring related to the motor.
-To get your airbag light to function properly, you run a wire from the EA1 plug to the light gray interior plug (either pin 4 or pin 5, I have read separate posts saying both and I chose not to do this step so I cannot confirm which pin it is.
