Don;t get too excited, its nothing half as nice as some of the ones I've seen on here... However it gets the job done, hopefully without being too restrictive.
Last summer me and lawnmower boy changed the rather sick 2.25 petrol in my land rover for a turboless 200TDI. This is quite a popular conversion these days as it is very easy to do. The only difficult bit is sorting the exhaust system out. There are generally 3 schools of thought on this subject. One is to make a rather funny shaped down pipe to connect on where the turbo used to go, and then onto the standard series system, however this involves fabricating some tight bends in exhaust tube and every time it rots out, it needs fabricating from scratch. The second idea is to modify the manifold off a late 2.5 N/A diesel to bolt onto the 200 TDI head and onto the standard exhaust system, however I personally fell its a bit of a bodge, as the manifold needs L shaped clamps to hold it down when finished as some of the studs don't line up. The 3rd method is to fabricate a manifold. Having nearly fitted a Perkins diesel into FUD instead of the 200 DI, I had seen the manifolds that Perkins use on them, very simple cast item that looks like a piece of box section, which has had 4 headers welded on... I decided if that was good enough for Perkins, then it was good enough for me. Lawnmower boy got the holes hacked, sorry cut the holes in some 60x60x4mm box for me and supplied all the rest of the bits, apart from the flanges which Metalkoi laser cut out for me last year.
Admittedly some of the welding isn't perfect, I suspect because we were trying to weld mild to stainless (header tubes, as thats all we had) but the rest of the welding is very good (Thanks to Will (lawnmowerboy) for doing most of the welding!)
We checked it for gas tightness and there were only one or two little pin prick holes, so we were quite pleased! The flanges warped very slightly in welding, but they pulled flat when bolted to the engine and it seals well. Painted it with stove paint and it looks almost professional (Who am I trying to kid!!!)
