1/07/2007 - GT40 Intake - 70mm Throttle Body - Drive shaft test fit - Finished TKO Mount |
|
 I ran across a GT40 intake on a local board and couldn't resist the purchase. The intake included both top and bottom pieces and a 1" Phenolic heat spacer. |
 I always really liked how this intake looked so I am happy with the purchase. The intake bore is 70mm which matches the EGR delete and keeps me from having to port the stock intake I was going to use. |
 With a new intake I couldn't leave the stock throttle body as shown in the first two pics on the car. It just didn't look right and would kill most of the benefits. I ran across this Accufab polished 70mm version on the same board. Notice a little difference in the bore size there?? lol |
 Here is the new throttle body installed with a cleaned up and polished idle air control solenoid. Much nicer looking. |
 Since I am eliminating the EGR for various reasons I purchased an EGR delete plate to mount the throttle cable, etc on. However the plate interferes with the stock fuel regulator on this intake so I cut up some 1/2" spacers and polished them to move out the linkage. It should work fine. Only possible throttle issue is the pedal to throttle arm ratio appears to be different on the original carb vs EFI. You get full throttle with less throttle pedal movement. I might have to move the connection point down on the throttle pedal. |
 I also drug out the old drive shaft that I used the last time the car was running (I think this is the one??) and was pleasantly surprised that it is near perfect in length to use with the TKO. It does use a smaller U Joint but I have run mixed U Joints in the past and will again. In fact the rear joint on this one is a mixed size to allow connecting to the existing 9" rear. |
 Speaking of the drive shaft... here is the difference between a C4 output shaft and the TKO 5 speed output. Just a little bigger. |
 Here is the finished modified FMX cross member. I added the support across the bottom and a T brace not shown here out of .125 steel. I also seam welded the mating surface (not shown here) of the spot welded two pieces. |
 Final work for the weekend included bending up the monte carlo bar out of 1 1/8" pipe to finish out the home made EFI export brace. I tested getting the distributor in and out and plug wires on/off without problems. |
 Rear/side view of the EFI export brace. I like the beefy pipe myself. Just need to pull it and final weld it now. |
