been thinking about a turbo upgrade, and was looking at the one on my truck , noticed that the housing has 1.00 AR stamped on the housing????
I had the understanding that the stock housing was an .84, I've attached two photos, any tech help on this would be a great help.
I'm not sure bud but it might have something to do with the area the truck was originally delivered (air density, humidity etc..) Are you the original owner? if there was a previous owner maybe he upgraded the housing already :dunno:
^^^ Correct. The 1.00 AR is on the wrong side. it's a stocker. Put a Banks Bighead and a ATS ported housing on it unless you plan on going big on injectors..
Can I get in on this thread? I too have an 02 7.3 and I'm wondering what's this about the Banks "Big head" and ATS ported housing? Please explain what these will do for jhp7.3 and me.
The BBH has a very stiff spring and it adjustable to dial in the exact maximum boost that you want. Even removing the "Red line" the stock unit will start to open as the spring is weak.
The ATS housing will eliminate "Surge" that is associated with performance tunes.
Sounds like a fair amount of work for a bandaid but I guess it could be done. Driving the stocker without the wastegate can be a little rough on the turbo but it can be done as long as you do it knowing that you are shortening it's life. By how much, I don't know.
I agree i wouldn't want to do away with the waste gate completly, but holding it closed a little longer seems like a good thing, plus the map sensor will defuel @27 psi
hey guys..what is the stock boost level of the truck? Don't these high performance chips increase the boost past 22lbs? If not..how do you get around this?
Also I was curious if you upgrade the turbo without injectors but have a TS 140HP tuner chip..will that supply enough fuel? If not what will happen.....either way if you have a upgraded turbo at stock boost levels wouldnt that lower EGT's and be benificial
yes the chips increase boost past 22 psi and to get around that, you need a MAP fooler.
as for the turbo questions - i'll let the other guys answer those
