Turbo Upgrade

[Natedogg625]

Is it possible to upgrade the turbo in an XR4TI or SVO?

 

[Red_LX]

Yes

 

[mr_woodster]

Yes its possible, im not sure it has been done before though.

 

[SVOconvLX85]

They came turbocharged???

yeah, most of the bigger turbos are a bolt on application. Your going to need to retune the computer, but it can be done. I beleive the only turbo that wont have an exact fit is the T4, but racer walsh has a t3/t4 hybrid that will bolt on.

Uh...no, you don't need to "retune" the computer to put on a bigger turbo.

Anyway I thought he meant to upgrade the turbo itself, i.e. turn it into a hybrid, which you can do. Just not many people actually do that themselves.

I thought that because of the more pressure from a bigger turbo, it could create the problem of over-boost and the computer needs to be recalibrated so the engine doesnt shut down

i've never had a bigger turbo "shut a motor down" only thing you need is more fuel pressure when you start adding boost. an adjustable fuel pressure reg usually is a good idea to have when you upgrade...

when you overboost a turbo 2.3 you really only blow a head gasket and a few other seals....

WTF are you talking about? That's what a wastegate and boost controller is for. Plus, if there's too much boost, the engine doesn't shut down, it blows up, generally.

go to the junk yard find a cummons turbo dezel dodge and yank the holset off that.

 

[Asha'man]

Yeah, because you see so many Cummins motors at the JY. eBay would be a better bet, but you'd need a lot more knowledge and fabrication skills than you obviously have right now to use it properly. No offense, but that's the way it is.

one of the 4 bangers i have has a bigger turbo on it than it originally had and when i get over boost, even witht the wastegate working properly, the computer doesnt allow that much boost, and momentarily hesitates the engine so some of the boost goes away

 

[140CILX-Coupe]

maybe the exhaust is blocking its performance.

Oh here in nebraska I see cummins dodges in the JY all the time....
