From France

I run with low oil level. So the crankshaft was too damaged (engine had 146 022 miles).

Now, the MR-S is back with another used engine, witch came from MR-S 2003 with only 104 000 miles.
I've founed the Celica C63 gear ratio little bit too long. So I bought another Celica GTS reconditionned transmission WITH LSD this time.
Here the video with stock ECU :
I installed Lotus S2 rear diffuser on the back of the car. I had to cut the rear bumper and made home-made bracket.
That wasn't difficult. The 2 holes fit with the stock "plastic diffuser" screws. I painted the diffuser in black paint for BBQ high temperature.

The result is not perfect. It really look better without the cuted rear bumper. As the car and diffuser are black, it's not so flashy.
The main goal is valided : it's efficient and hot air don't stay in engine bay. Of course, it not working without cuting rear bumper.

Some news here :

- replaced the steering wheel by 330mm. The hub is from Toyota Celica 1998 (modification needed to fit).
Steering requierd more force to turn, give quicker response and add feedback.

- reinforced the under chassis by installing Roadney Racing under brace (made in France).
The chassis is stiffer, especially on bumpy roads, LSD engagement is smoother. Doors closing is slightly better.

- replaced the factory bulbs by red LED bulbs (bought in Canada). Seller checked fitting before sending the right LED bulbs.
Lighting night is a huge improvment (even on lighter setting). On sunny day, the higher light is helpfull to see the tachometer.

- took time to repaint tires letters in yellow and putting reflective tape on the side of the OZ wheels and rear crash bar.
Reflective tape are illuminated by direct AND indirect light. Most product are "direct light" only. Small thing but expensive.

- bought an extremly/expensive rare front hood from Japan. I could buy another MR-S in bad shape for the price.
Fitting is very good and quality without reworking on the fiber is almost excellent level (~20% lighter than OEM).

I've bought a Amuse R1 Extra Titan exhaust.
It's a street legal muffler that weight 3,85kg (packagging with muffler weight 4,11kg).
I like the sound from exterior (come from exhaust tip), but in car it sound different (come from the muffler).
Titanium exhaust smell too, I'm not kidding. It's like weld smell but smooth until it smell "fine" to the noise.

There is no drone. From exterior, anyone can hear that this is not factory because of more decibel.
It's enoughly quiet to drive without annoying sleepping people at midnight.

Compare to my Malian, the Amuse add instant throttle response and more torque.
This is not a placebo effect. I could really felt it in the seat and on rainy road.
I could hit far less pedal gas to make moving the car.

I removed it and re-intalled the Malian Race exhaust.
The Amuse is too quiet for me so it's for sale.

I bought a Zero Exhaust header + sport cat. The brand is based in UK.
Good product sold with almost anything except of the exhaust header gasket. Welds are good.
I asked to have two more bungs > AFR sensor and for the O² sensor in case I would keeping linked O² sensor.
Zero Exhaust is not installed yet.
