Its a "rising rate" fuel pressure regulator, senses the manifold pressure and adjusts the fuel pressure to match the increase. G60 is the way to go if you have all the parts. Keep us posted, am interested in your project. My 16V engine is now built and the turbo is on its way ;D, Steve.

interesting stuff MK1. I'd be interested to know how the 2 litre Gets on when its done. I always thought that when turbo charging you have to fit a thicker head gaket or a spacer to lower the compression ratio so that your not gonna blow/quote]  you could take out your conrods and have a machine shop knock up some offset small end bushes this will lower the pistons and effectively lower the compression.this will retain the strength in the piston crown where you need it most on a turbo engine

Agree that the small end mod is a more stable way to go, but I looked at the the bearing and 2mm would not leave a lot of bearing, so the piston it was ;). Will let you know if I was wrong ::). Steve :)

Machining bits off sounds a bit iffy?

The pistons have been machined by the factory to clear the valves, so I saw no problem taking some off the crown to lower the compression. I know that forged pistons are the way to go, but I want to keep the cost realistic. If it goes well and melts a piston, a set of forged pistons will go in. The small end bush is also under a lot of load when boosted, what would you do?. I am using what I have, and the resources availible. ;). Will keep posting progress for those who are interested, and if anyone has any ideas, please add to this thread  :). Steve.

I would put a thicker head gasket in and some decent pistons. Otherwise its bound to go bang sooner or later, probably sooner  ;) Good Luck  :D

Thicker head gasket would mean vernier pulley, pistons may come yet ;). Will post as I go. Steve

I would think thicker head gasket would be essential to stop it going BANG!  :o   What engine you putting a turbo on, 9A?
