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.

been looking at the wiring, so..

why do we need our original 5sfe wiring. im assuming just that part from the fusebox to the lamps. cuz the rest is not being used. apart to use it to leghten wires?

im confused. You lengthen some wires and repinn some, thats fine, but whats the real use of the rest of the harness.

you use the entire beams harness.

this is the wiring IIRC

where the fuse box is in the engine bay the engine harness unplugs from it.
You plug the beams engine harness into your fuse box in your engine bay, that plug is EA1.
Each pin on EA1 is numbered, you need to bridge together pins 4 and 17 (the US harness doesn't have pin 17 and beams pin 17 needs + when 4 has it.)

on the other end of the beams engine harness there are 3 interior plugs (3 vertical plugs right next to the ECU).
The beams ECU has 4 plugs and the circuit opening relay (COR).
The 3 interior plugs are white (19 pins), light grey (13 pins) and dark grey (17 pins)
the black wire from the white plug (pin #18) must be removed and re-pinned to the dark grey plug into pin # 17.

that is the wiring. Do those things and the car starts, drives, ect..
fyi if you want cruise control or airbag light to work, there's a bit more.

As for extending the harness, you would need to extend some wires to fit into the LHD configuration or you make a new hole in the firewall and put the harness through it there.
