Swap: 3sge Beams into 94GT-RIP=DEAD Options

[turnip]

70mph and wall equals the devastation.













Good Day All.

I have some questions that i did not get from trolling and searchings. I hope that the some of the swap gurus can chime in.

Project: Swap 6gen JDM 3SGE Beams into 1994 USDM GT.
Goals: 200whp and reliability
Use: Race - Car will be completely gutted including all glass and prepped for racing.

Current setup is a stock 5SFE with 60k miles.
Transplanting 3SGE Beams and LSD S54 tranny. Yet to be procured. I have few I am looking at with money in hand.

Drivetrain - The 5SFE has an S54 on it and I assume that the axles and clutch will interchange?
Question#1 - Did any of the USDM Celicas with the S54 have stock LSD?
Question#2 - Flywheel and clutch upgrade? What are my options?

Electrical - Since its a same Gen Celica did the harnesses drastically change over the lifecycle of the 6th Gen? Pre Post OdbII?
Question#1 - Can someone confirm that the stock USDM harness will plug and play with the ECU and Beams? With exception to wires being lenghted to accomodate RHD vs LHD.
Question#2 - If my assumptions for one is complete off please guide me in the correct direction.
Question#3 - Dash Cluster - Racing I really do not care about speed as much as temps and RPM. I do not want to buy an JDM dash cluster is there a work around to make the stock one work? Otherwise will likely go the DEFI Link route.
Question#4 ODBII vs ODB1 The 94 is ODB1. The Beams will be ODBII Has anyone got this to work on a pre 96 vehicle? I only ask as ODB is a good way to check sensor failure vs the plug and play method.


Tuning
Goal of 200whp with Intake, Exhaust upgrade, no cat, no P/S, no A/C, Flywheel upgrade, ecu, ect.
Questions1 - Does anyone have experience with any of the JDM ECUs such as Mines, Toms, I.Mec, Blitz?
Question#2 - Headers any experience with C-One, Apexi, HKS, Fujitsubo?
Question#3 - Crank/Balancer Pulley.. Is there one?


Thanks in advance.

It's not just pins 4 and 17 on EA1, but interior wires also. I told you it wasn't plug and play...
hint : if it's not starting, refer to "starting and charging" in both manuals

start with this...
was you car m/t ? if so, you need to switch a wire from one interior plug to another. Interior plugs are the 3 plugs next to the ECU that plug in vertically. If it was an auto there's additional wiring like I did with Tina's, Stef's, and Jim's car but it's move involed and difficult to explain online, but I'll try if you need me to, just let me know.

m/t - you need to pull the black wire (pin 18) from the white plug and move it to the dark grey plug to pin 17. That is the clutch start switch wire. Overseas and US have the csw wire in different spots, so you need to move pin 18 from the white plug to pin 17 in the dark grey one, just like the 5s harness.

didn't you compare the pins in the 2 harnesses before you started ?

First off. Thank you. I did look over the harness before starting but must say I was a little confused as its a little intimidating when you dig into it. Thats when I decided to post up and start doing more research.

So now that you have guided me in the right direction. Pin 18(white) and Pin17(dark grey) are now connected. In reviewing all of the 3 vertical plugs, here is what I have that does not match.


Plug E6 (light grey)
USDM Harness has Pin 4 - missing on Beams harness - wire color blue with orange rings

Plug E3 (Dark Grey)
USDM harness has Pin 1 - Beams Pin 8 - Wire color white with blue stripe
USDM harness has Pin 10 - 0 on Beams - wire color blue with white stripe
USDM harness has Pin 16 - 0 on Beams - wire color pink
USDM harness missing Pin 9 - Beams has this - wire color solid grey/silver ring

Thanks
