Default 02 WRX Stock Turbo vs 06 WRX Stock Turbo

Alright, without doing much research I have a question.

I have an 02 WRX with a stock turbo and need to upgrade, however I only need to upgrade right now because my turbo is too old and I think some of the bearings are going bad, the turbo has 74K miles on it and has been pushing 18+ psi for 35K of those miles.

I kinda want to just grab a stock turbo off an 06 WRX.... what is the size difference. What turbo is on the 06 WRX?

HELP PLEASE

You might as well have some P&P done on the turbo if your going to swap with a stock unit. You won't regret it!

I have an 04 and did an install with an 06 TD04. I found two differences.

First, the restrictor pills are different. The 06 had a smaller diameter opening in the center. Caused my car to overboost like crazy until I changed it out and adjusted the wastegate actuator arm.

Second, the compressor housing does not have a slight 'bend' like my 04 TD04 did. It made the connection to the intercooler hose a little difficult, but possible.

Just my 2 cents.

So when u swapped the 2.0 turbo with the 2.5 turbo did u have to do anything with the wastegate actuator?

And how does the car feel with the turbo on it, and differences?

Why would the car feel different with the tdo4 from an 06 which is exactly the same as the tdo4 from a 2002?

Wastegate actuators also need to be swapped. The springs have different tensions.

Everything felt the same...

Very interested to know what type of research you did as these questions should not be questions if you researched.
