this site is great! Thanks a bunch!

 

I believe they have different cams and turbos as far as the motor. The 6-speed has different gearing as well as the rearend.

 

Hmm, kinda looks like mine! I just got my first Supra RHD TT hardtop.

 

you guys are quick! awesome! Thanks.... Euro and JDM MK4's are the same?

 

And may I add Injectors 440 I think, No Resister Solenoid, and They run on Map sensors.

 

OOPs you are correct I failed to add these facts.



Greetings and welcome to the Forum Hin! :wavey:

 

Nope, US and Europe are ABOUT the same with some differences:
Euro spec has additional:
-hood scoop
-differential oil cooler
-retractable active front spoiler

Jap Spec has a pretty different setup than the export versions-cams are different, turbos, injectors, engine management.

Hope that answers your questions.

 

There are quite a few , obviously right handed dash parts and harness with accociated gauging eg MPH / KLM, different turbos ( manifold ?)and sum plumbing fittings , and injectors 550 low imp with resistor pack USDM and 440 high imp JDM , exhaust cam profile on the USDM and associated fuel and ignition maps plus pin outs on the USDM ECU have sum diffs. USDM 2J uses MAF , Jdm uses MAP , USDM EGR not on JDM , USDM has larger fuel pump standard than JDM. There is also variant model use of the larger 4 Piston Front / 2 Piston rear brakes supplied on all USDM TT Supra's with larger 17 inch stock wheels with JDM Version depending on Model and year can be supplied with the smaller 2 Piston front / 1 piston rear and smaller 16 inch stock wheels . Thats about all i can think of for now .

 

Yeah also sept 1997 - 2002 JDM TT supras are VVTI and use MAF

 

It's the inlet cam that's different - milder duration and slightly less lift on the JDM.

Traction control system is different on the later facelift JDM cars.

Some JDM cars came with smaller discs and sliding calipers from the factory as well as a different master cylinder. 17" wheels were an option unless you already picked the larger brakes in which case the 17" wheels were necessary.

And as others have pointed out - no bonnet scoop, no diff cooler, 440 high imp injectors, no resistor pack, larger (yes larger) ceramic turbined turbos, different exh manifold and 1st cat, no EG recirc, different plenum chamber, different abs system, different fuel pump and hanger (Walbro 342 is the correct drop in, not 341), no MAF (except the vvti's), optional Torsen differential, optional stiffer Bilstein based suspension, no rear foglights, plastic lenses on the headlights, and several trim/equipment options - GZ RZ RZ-S...

Probably more but that's it off the top of my head.
