Turbo differences

[Texas Flyer]

I recently bought a 2000 F350 7.3 truck. Several friends of mine have similar trucks, but their turbos appear to have smaller housings. Mine looks like theirs, they all say Garrett on the side, but mine is visibly larger. Does this mean its an aftermarket turbo, or did Ford use different turbo housings in different years?


Thanks for the info!

What years are your buddy's trucks?

IIRC the 02-03's have a slightly bigger housing.

My friends have trucks spanning the whole range of 7.3s. One is a 99, one is a 01, and one is an 02. They all have much smaller turbo housings and pipes going around to the intercooler. Also, the smaller ones seem to build more boost pressure than mine. I can only get up to about 12 psi on my Isspro gauge when I'm really on it.

I'm thinking about putting the smaller system on mine to get better boost and EGTs. Any thoughts?

With out a chip your not going to push more than 18 psi. Post a pic of your turbo and hoses. What all does your truck have done to it?

I'll try and upload a pic tomorrow.

I've got a big boost and a Hypertech Extreme program on it. I was running it on stage 2, then I just upped it to stage 3 today to try it out. I just got the Isspro EV2 gauges put on yesterday, so I'm just starting to see these readings for the first time. I'm learning as I go!

Ok, here are a couple of pics I took today of my turbo. I'm hoping someone can tell me what I've got. I hope you can see in the pics how much bigger the housing is than the others that I've seen. I think I may want to get the smaller turbo installed. If I do, it sould produce more boost and give me lower EGTs, right?

Looks stock..

Looks stock to me.
The 99 could be an e99 which would have a smaller turbo.
