Chad Posted September 15, 2006 Report Share Posted September 15, 2006 It gets asked often : "what is different about the magna that requires modification"?. Here is what I do to the magnas: 1- move stat housing to stock U.S. spec location 2- remove (grind off) the old housing and weld it up 3- add water port for the heater core between #3 and #4 4- add brake booster port on #4 5- drill/tap port for coolant temp sensor 6- resize old pipe nipple on new stat housing for 2nd temp sensor 7- resize (weld in) rear water port between #3 and 4 8- cut off and cap old TB flange 9- cut and weld new TB flange in for mustang TB 10- weld of throttle bracket 11- drill/tap ports for map sensor and boost/vac items (gages/FPR/bov etc) This is what Glen did/does: 1- move stat housing to stock US spec location 2- cap only* the old housing3- add water port for the heater core between #3 and #4 5- drill/tap port for coolant temp sensor 7- resize (weld in) rear water port between #3 and 4 (or he sends an adapter plate) 8- cut off and cap old TB flange 9- cut and weld new TB flange in for mustang TB It would take a skilled first timer about 5 hours to do my mods, and about 3-1/2 hours to do the Glen modifications. If you have a good fab shop, you can use these hours for estimiating cost of moficication. If you do not have a good selection of metal working shop tools, it will take conciderably longer, but is still totaly do-able. This will require TIG welding, MIG won't cut it, it tends to be a pourous weld (will leak coolant) when workign with cast aluminum. I make all my flanges, brackets and bungs. This is all basic fabrication, no tricks or special knowledge. If there are further specifics, please post here and I will try to elaborate. If I don't read your post right away, PM me and I'll reply here. Link to comment Share on other sites More sharing options...
