GM CAI and 103mm TB

Nightfire · 07-05-2021, 10:36 AM

Hey all, I have a question if the 103MM TB with fit the GM Performance CAI. I know the roto Fab would be better suited but I have the GM one know and just trying to see if it would fit or what I would need to make it fit. Thanks in advance!!

Measure the ID and OD on the tube for the GM, then call the TB manufacturer and ask for an adapter.

EDIT: now that I look at the tube, you may not be able to bend it far enough out of the way unless the adapter is very short. Might be better to sell it and just move up to the Big Gulp (presuming you're tuned).

What other modifications have been done or are planned for the engine?

Get a regular Roto-fab if you're still na and if you have a pd blower do a big gulp.

I ordered Headers and the MSD Intake. Was going to do the 95mm but not even sure that would fit. May need to pull off and measure.

Will the regular Roto need an adapter or will it just fit? What about JLT?

Regular rotofab fits without any adapters. Jlt should also fit but not much info on how well it performs. Rotofab is going to be what most tuners recommend as it's pretty much the gold standard around here. I run a msd with a 103 with the standard rotofab. If they had a big gulp for na cars I'd run that but the don't and they don't have any plans to make one as I have asked them numerous times about it.

I ran the GM and RF with a 95mm. You won’t be leaving much on the table by choosing the 95 over the 103 with that set up.
