couple of questions...

i have a 94 f350 7.3l idi that i have been wanting to do minor mods to.

i have done research on a diy intake but have inly found them for 99+ psd.

i was wondering if any of the fellow idi owners have done this and if so how? could it be made out of pvc?

also has anyone installed a downpipe on their idi? can you tell a differnce in power? what about ease of installation?

ive also been thinking about exaust. maybe straight pipes but i think itd be too loud. any comments?

any input would be appreciated

Sounds better than before and I can slightly hear the turbo if Im standing next to the tailpipe. Sounds nothing like a 6.0 but, much more reliable.

It should be fairly simple to do a DIY intake. Either use PVC of exhaust tubing.

Yes actually they do make a type of kit it from K&N. Here is the link 85-1060 - K&N Other, Universal Plenum
Jst make sure that u measure your flange size but it is the same size as a normal 4 barrel carb. Have something similar to this on my 1993 idi!

DIY is fairly easy, just think up something and make it. Everyones is different.

This is my truck, straight piped. It has a turbo kit thats like the factory turbo, except better downpipe (which yes, it does help hp, but also lowers EGT's.).
