killinprixs Posted August 14, 2008 Report 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
MonteCarloDude Posted August 14, 2008 Report 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
Brian P Posted August 14, 2008 Report 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
BIGBULS Posted August 14, 2008 Report 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
1QUICKHATCH Posted August 15, 2008 Report 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! Quote
