thats what im running a 92MM NW but its so big i can fit my fist in were the throttle blade is.

i know FAST makes a adaptor plate to run the stock 78MM TB with the LSXRT thats what im goin to try nexted. if that dosent work im all done with this intake and putting a TBSS/NBSS intake on it and calling it a day.

 

There is 1 video on youtube, mrbgray30, truck has borla xr-1 in video, all other videos are magnaflow muffler.

The TB's are known to create driveability issues, but to me it sounded like a big vaccumm leak you had.

 

I just orderd a adaptor plate from CBM motorsports to mount the 78MM TB to the 102MM intake well see what happens

 

I don't think 92 is too big... I have been running one on a TBSS intake with no issues at all.
I think it's these wacky intakes not sealing...

 

Twolow- did you try to torque the lower half of the shell down first and then install the upper half? When I called fast that's what they recommended to me when I called about my intake. There was a slight gap the size of a business card.

 

Yup I torqued the upper half to the lower half before I installed it on the truck then put the intake on the truck and torqued it down to the cylinder heads just like the directions say to do.

I also applied small amount of silicone to the back rear section Like the directions say to do.

 

No torque lower half to engine then upper half to lower/ engine.

 

Don't know how that's possible since there's no way to get to the three rear bolts once it's on the truck.

 

True, I'm gla I didn't tak his advice. I already have it sealed up ready to install.

 

im pretty fed up with comp cams there basically useless in my book
