Looking to swap a 6 speed into my 2000 GT, from the research I’ve done it says it’s a direct swap and bolt on, just wanting to confirm this.

Yes, this was my original plan before I came across a motor and transmission deal i couldn't pass up. The only difference, dimension wise, is the end of the transmission sticks out a little further. Makes clearance to the driver side of the frame a little tighter.

It really depends. It's not directly bolt on, there are some things you'll need, but basically bolt on.
IF your current setup is an automatic, it's nearly impossible to do. Only can swap from C56 (5-speed)to C60 (6-speed). Monkey Wrench Racing is a good source of information.

What would be the things he would need as this is pretty vague? They said they were going from a 5 speed to a 6 speed on a 2000 GT so it'll be the C56 to C60. Other than tools and maintenance items that "should" be replaced, the only thing I could see are the speed and backup sensor but those are usually still attached to the transmission when they are sold. Just trying to give them good info before they get started on the job.

Sorry, missed the title where he said C56 to C60 swap. Everything listed below is bolt on, but as you can see it's a bit more involved than just swapping 1 for 1. Here is what is needed...

Parts required – engine swap
  • 2ZZ engine (from any year and model) with sensors, VV solenoids.
  • Intake manifold, throttle body from 2000-02 Celica GTS or 2005 Lotus Elise.
  • Throttle cable from 2000-02 Celica GTS
  • Knock sensor- you can use a 2000-01 Celica GTS knock sensor or your stock Celica GT knock sensor.
  • ECU: you can use a US-spec 2000-01 Celica GTS MT stock ECU or a 2ZZ Power FC. European and Japanese stock ECUs have an immobilizer feature so they will not function once swapped into a different car.
  • Injectors: if using a stock Celica GTS ECU, you should use the same model and year injectors as the ECU. If using a Power FC you can use any stock 2zz injectors or aftermarket injectors. 1ZZ stock injectors are too small with either ECU..
  • 2ZZ flywheel – if your engine came with a stock 2ZZ flywheel you can use that, just be sure to get it resurfaced. Most people prefer to upgrade to an MWR or Fidanza unit for quicker response and improved acceleration.
  • Wiring – your stock 1ZZ engine wiring harness will work but you’ll need the MWR VVL connector kit to add the VVL connections.
  • Header – Celcia GTS, Matrix/Corolla or Lotus stock header or PPE 2ZZ Celica Header. If using a stock header and engine has air injection, header must have air injection.
  • Midpipe/Catpipe – Celcia GTS stock or aftermarket midpipe to match stock Celica GTS header or PPE midpipe to match PPE header. Some have adapted the Celica GT midpipe to make it fit with stock GTS header but the flanges do not match and the GT midpipe and cat are smaller so power is compromised.
  • Air intake – Any Celica GTS cold air intake will work. Celica GTS stock air inlet tube and air box also fits. GT airbox or cold air intake will not work.
  • Alternator – the 1zz alternator bolts up fine. There have been a few reports of 1zz alternator failures so some people prefer a 2zz alternator.
  • Mounts – the three transmission mounts are the same for 1ZZ and 2ZZ manual cars. The one engine mount is the same as well, you just need the steel engine-side part of the mount that comes with the 2ZZ engine.
  • Gauge cluster – the stock GT cluster works fine. The tach only goes to 8000 so the needle will stop climbing just before you hit the 2ZZ’s rev limiter. You can swap in a GTS gauge cluster but your car’s odometer will no longer be original and will display an incorrect mileage.
Transmission

Your stock 5-speed will bolt to the 2ZZ and work ok with no modification. The 2ZZ is normally paired with a 4.5:1 6-speed transmission with close ratios; this suits the 2ZZ’s peaky power band MUCH better and you’ll find it’s a lot more fun to drive. Upgrading to the 6-speed is obviously easiest at the time of the engine swap but if budget doesn’t allow for that you can always do it later.

  • Toyota MWR transmissions – choose from 3.9 , 4.3 and 4.5:1 final drives in these brand new affordable 6-speed transmissions which available with or without a TRD helical LSD. These transmissions come ready to install .
  • Used 2000-05 Celcia GTS 6-speed transmission – get it from a trusted source; high mile or abused transmissions may have synchro issues. A Matrix/Corolla transmission will not work in the Celica.
Your GT is an automatic? That’s trouble. The GT and GTS use completely different automatic transmissions. You can’t run a GT auto trans with a GTS ECU. Even if you get a GTS auto trans you still have some serious wiring problems. You’re best off sticking with a 1ZZ engine or tackling the difficult job of converting your car to 2ZZ manual. 2ZZ automatics are generally no faster than 1ZZ automatics anyway.

Uh... Pretty sure he was just asking about mating a c60 to his 1zz engine... Not a complete 2zz/c60 swap.

This of course would be a great time to upgrade your clutch and flywheel. At the very least, replace throw out bearing, clean up the moving parts inside the belhousing and relube pivot points.
