killinprixs Posted August 14, 2008 Report Share Posted August 14, 2008 does anyone know what throttle body is on the TGP 3.1? I was going to order ported upper/lower intakes from 60degreev6 and it said optional porting for 56mm tb, what is it stock 52mm? Quote Link to comment Share on other sites More sharing options...
MonteCarloDude Posted August 14, 2008 Report Share Posted August 14, 2008 I know the 3100 TB is 52 mm and the 3400 is 56 mm, so my guess would be 50 or 52. Quote Link to comment Share on other sites More sharing options...
Brian P Posted August 14, 2008 Report Share Posted August 14, 2008 yeah stock 3100 W-body, N-body is 52mm, the A-bodies got that weird TB with the built-in MAF and was even smaller! Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted August 14, 2008 Report Share Posted August 14, 2008 All of the MFI TB's were 52mm IIRC (whether turbo or not). I know Mantapart sold/sells 56mm TB's and RSM had 59mm TB's for the 3.1's............ Quote Link to comment Share on other sites More sharing options...
1QUICKHATCH Posted August 15, 2008 Report Share Posted August 15, 2008 all of the 2.8/3.1 mpfi's got 52mm with or with out turbo. I am getting a local machine shop to bore out a stock 3.1 TB for me soon for a 56mm plate. If your interested let me know I can probly get an extra one done at the same time!
