I have just bought a 1986 astra with a et pulsar turbo motor... it has full 2.5 inch exhaust and is running 7 psi.Have a return flow intercooler that i will get piping made for soon aswell. Just wondering what i need to install a t25 instead of the stock turbo.. thanks guys

You need just the turbo & thats it, t25's run oil & water lines but the water isnt overly necessary on them aslong as you let the car cool down for a short period of time, you can also put the t2 compressor housing on the t25 so the piping stays the same as the t25 have a 3 bolt flange from the compressor housing that comes up into like a 2" pipe, so if you can swap the housing over id suggest doing so, I did this to my exa a few years ago & the boost comes on every so slightly later than the T2 but pulls through more of the rev range

hey guys.
i have just recently purchased an n12 exa turbo. car is standard, but the turbo has shat itself.
wanting to install a T25, any requirements needed for me to do this?

u will need to rotate the turbo from rwd to fwd setup then the actuator will need to be modified then u will need a custom dump pipe cause t2 4 bolt and t25/t28 is 5 bolt then u will need to shorten the cross over pipe from tb to turbo and shorten the pipe from log to turbo pretty easy job just time consuming goodluck
