Nowthen boys and girls after a good few months of motoring ive decided im going have a go at adding some huff and puff to my engine. Going down the old Renault 5 GT turbo solex route, got a turbo, gona fit a deep sump and extra oil cooler and pretty much got my head around the set up after many hours of research. Now this is just gona be my first attempt and I wanna do this at a low cost because if I like the way it goes I think I will sink some decent cash into a full rebuild with fuel injection......the hole hog! So Ive been thinking about timing and more to the point retarding it whilst under load/boost. Dont wanna just limit the advance as this will mean at higher revs whist not under load i,e. criusing the timing will affectively be 10 or so degs out which will cause heat and economy issues. I have looking into the volvo/saab distributors which have boost retard fitted just like vac advance in reveres not wanting to be to crude but these are as rare as hens teeth and have given up looking for one. So my idea is to use a small actuator from a turbo wastegate modified to replace the vac unit on the dizzy or to maybe actually turn the complete dizzy in the casing to retard the ignition as the boost rises. Just wondered if anyone had seen or heard of this before or please tell me if im just being mad!?! By the way I like tinkering so this aint all to keep it on the cheep i just like a challenge!
