This post is the same as what I just posted in my car build section, but I want to keep all the engine swap/subframe info here in one place for those who are just interested in the swap process.
Well I did finish the header last week and I cut out the front tube of the subframe and made a new removable one so I will be able to take the header and the clutch slave cylinder off the car without pulling the engine. My design has the front horizontal tube behind the front bumper, there is room behind there for a tube, that is how I picked the height. There are two short tubes positioned longitudinally that I used for anchors at the front for the other tubes. Once I removed the front tube I welded some metric nuts to the back of some circular caps which I then welded into the short anchor tubes. This allowed me to construct a new horizontal transversally mounted tube for the subframe that I could remove. I will be pulling the engine soon to finish up the welding on the subframe and give it a coat of paint. I will be painting up some of the bare metal to seal it off pretty soon because I am going to have to move the Travelle"R" from my friends garage soon as he needs it for a few weeks to do some work of his own. So it will be back at home in my portable garage, so I don't want it to rust up, especially as it is turning to fall here and there will be a lot more moisture in the air. The good news is that it will be more convenient for me to pop outside and do some work whenever I have a little time.
Here are some pics.
Header done with front tube cut out of the subframe.
Caps with captive nuts TIG welded on.
New removable tube bolted on.
Couple more shots to show the little clearance there is between the front tube and the header and clutch slave.
they look so neat and strong
