does anyone know if something like the MSD timing retard device will work on our 1.8-2.0 engines? If I got the BEGI kit I'd want to run 8psi using a bigger IC but FM says I'd need to retard the timing to be safe/reliable.

yes it's true, when I see a pic of a Silvia or even a Ecliple I have - intercooler envy.

 

I have one for mine but it's a first gen with distributor but i think msd makes one for the coil pack. Ask any supplier of Msd. There's one guy here in Quebec that runs a turbo mp3. Check in the members ride his name his Stou. http://www.100megs12.com/%7Ecpq/www/index.htm
