I recently built a CIS stroked 1.8l 8v motor with a Rajay turbo set up. I have been trying to keep this build old school, I am using the Audi 5000 WUR, Volvo air meter.
I am using a Impaco TC2 boost controller which restricts the volume of air to the engine under boost.
As things progress I am finding that I don't like how the TC2 limits the engine speed. It creates a lot of heat and it is kind of annoying when the engine peaks out a 4000 rpm under boost.
I have been looking into other boost controller systems such as blow off vales, trying to stick to 80s set ups.
I will try to post some pics soon, does anyone have any experience with any of these set ups?
