Removed new carburetor, found casting defect

The LC Engineering tech suggested that we remove the carburetor, to check that the throttle butterflies were centered.  We found that the secondary was not.  We also noticed a small casting defect on the throttle body.  Further inspection found that the hole went all of the way through, so we had to return the carburetor.  I called LC and they shipped a replacement that day.  I also emailed Weber.  Weber wanted the defective carburetor, so they offered an upgrade to a 38.  We had that in our hands the next day!

Installed Weber 38

Image
Today we installed the Weber 38 that Redline sent as a replacement for the defective 32/36.  Both Redline and LC Engineering were extremely helpful with install and tuning questions.  Unfortunately, the adapter plates had an issue which caused the recess for linkage clearance to be oriented wrong. This is the proper orientation of the plates (notice, the center bolt holes don't line up) Grinding to make room for the linkage. Our linkage extension tube Our linkage adapter

Installed a Pace-Setter header

Image
When we purchased the car, the previous owner gave us a header that he had planned to install.  We looked up the model number (Pace-Setter 70-1188) and found out that it was intended for a mid 80's 22re powered pickup.  That's when we decided to use the stock manifold.  We changed our mind and purchased a stainless steel header, cheap on ebay, that was supposed to fit our '07 Celica.   Today we found out that it would not clear the steering box on one side and flywheel housing on the other. When we tried the Pace-Setter, it almost dropped right in (but the stock down pipe heat shield was just touching which kept the head flange from fitting over all studs).  Removing one (top) and loosening the other two heat shield bolts was enough to free it up.

Weber Carburetor install

Image
Today, Kyle and I installed the Weber Carburetor that we purchased from LC Engineering.  We also removed and plugged various obsolete vacuum ports and a few unused water temperature sensor ports. The linkage adapter that was supplied with the kit was too flimsy, in our opinion.  The weber carburetor linkage is about an inch farther away from the firewall, but the stock linkage was able to hinge enough to connect to it.  That hinging seemed to be causing a little binding, so we figured out a way to extend it (not pictured here, should be posted soon).  We decided to reuse the stock linkage connector, which was not keyed.  Since it needed to be keyed to prevent slippage, we cut the keyed section out of the Weber linkage and tack welded it on over the existing hole. The new carburetor has issues with its linkages sticking (not returning completely to the stops).  I plan to call LC tomorrow morning to find out how we can remedy that.
