Thought I'd start a thread on my 1974 RX4 hardtop.
I bought around 2 years ago after previously having a 13b turbo 1973 RX4 hardtop and an '86 Series 4 RX7 turbo over the last 15 years.
The car had a carby 13b and first gen RX7 5 speed, it ran well but I needed more power. I think of the RX4 as mazdas "muscle car" so it needed a engine with the muscle, hence a 20b
The RX4 as I bought it....
Striped and painted the crossmember and replaced tie rods, sway bar and bushes.
All installed!
