changing dump - from above?
I took the hotside off the the turbo when I did mine back in the day and ported it while I was doing the O2 housing. Taking the whole hotside off allows you to remove the O2 on the bench which is nice as others have said.
take the radiator out and do it right. mines a lil dented because i was impatient at first and tried it with the rad in. i eventully took the radiator out.
and get new gaskets.
and get new gaskets.
I took off the hotside and didn't have any issues with the radiator. The only time i touched the radiator was getting the WG actuator off the flapper, but that took <1min. removing the radiator isn't "doing it right"
I think risk of damaging the radiator is greater pulling it out than sliding something in front of it to protect it just in case. Also doing the hotside method your doing 0 wrenching in the car except to remove the manifold, bracket, and downpipe (nowhere near the radiator fins). Then you take it all apart on a bench, do some extra porting if u want/can. Then put it all back together and slide back into place, its really the simplest method....but to each its own i guess
Reuse stock bolts if they are still good. In fact i would not use any bolts or gaskets that come with most aftermarket O2 housings.
On the O2 housings i have done i have always had 1-2 bolts strip or cross thread so be prepared.

Tephra- I changed mine without removing the radiator either, same way as some of the other guys just removing the exhaust manifold, splitting the housing from the CHRA, and removed the hotside and o2 housing as one piece. It took about 3 hours total, but only took that long because one of the manifold studs broke on me so I spent most of the time trying to think of a way to fix it. PB blaster and a fire wrench (aka small map gas torch) will be your best friends for some of the hardware.
