Questions about my SPS 66 turbo

[E7mack96]

Today, i finally got around to installing the SPS66 turbo. I was under the impression that it had a true 4" outet. Mine has a 3. 5" outlet. They did sell me the downpipe that works perfectly with it. I really thought that they said it was a 4" exaust. Am I on crack?



Also, that thing is one badaasss turbo. i literally put the truck sideways on the highway the first time i rolled on the throttle. I was rolling about 55 in 6th, and the thing pegged at like 39-40 psi and broke traction. :--) Oo.

Also the entire ATS manifold / SPS66 turbo changeout took like 2 hours total, except the oil return line took another 2 hours. I even thought that one of the 10mm return line bolts fell into the line itself After looking from the topside it was found between 2 parts of the frame, thank god. !!



Did everyone else have a hard friggin time putting the drain line on the turbo? That inside bolt by the wastegate diaphram is about impossible.

You put the drain tube on the turbo before you installed it right??

Should be a true 4" OD since you can run the stock downpipe (and turbo cast iron elbow) on a 2004. 5 with it.

luken - no i did not, as i unbolted it from the original and removed the original turbo and manifold as a unit. I did mount the turbo to the new manifold before install, however.



Next time, I'll install the drain tube first.

your 03 should be 3. 5 inch exhaust up to the cat i think... . i could be wrong.



HO 04's and 04. 5's started the full 4 inch system... . again, i could be wrong...



this is the turbo i have been thinking about going to.

i did the same thing. bolted the turbo up and had everything complete except for the two ten mm bolts for the drain. i got one started and then couldn't get the other one started. owell i finally got it.

I like my SP66 pretty well. EGT's are a lot higher than I think they should be, from what I was told when I purchased it. And towing with it takes a little getting used to. When you change gears, the turbo lags a little, then BOOOM, 40 psi!. With 20k behind you, you kinda wonder when the transmission is gonna explode. The 6 speed is definately tough so far. I actually barked the tires in 2nd and 4rd with 16k on the trailer last week. My buddy wanted me to "show him what it will do with a load".

I noticed higher cruising EGT - but lower overall EGT



But I think thats normal... My biggest EGT reduction was adding the Injectors...

03 & 04 HO's are 3. 5" to the muffler, no cat.

04. 5 is when the full 4" started... with a cat. The 03's and early 04's have a 3. 5", no cat.
