I detest the 'normal' routing for FMIC pipework on these cars. It's like spagetti all round the wings.
The setup that has really caught my eye is the RS500 where the FMIC pipes go over the top of the water rad so routing is as short as it can possibly be. This is similar to a setup I saw years ago in a very small shopping car with a tiny turbocharged engine.
I know Edd (Treacle) has done some research on this and I think it looked feasable on a 205. I also know that a guy on CCUK has found an alloy RS500 coolant rad to be better than standard or alloy 185 rad on a rally car build so should be adequate.
http://www.celica-club.co.uk/forum/inde ... ld/page-12I'm planning to go for this style setup on my 185, but I'm expecting to need custom radiators as the 185 has an inch or 2 less height available.
