Some of you might be asking why is he removing the hotside well heres the deal. WHen i was putting my licp on when i had it i stripped out the bolt holes on the compressor housing where th licp pipe bolts to the turbo and i believe i have a leak there. Which might explain why my times are so crappy. So i bought a used 03-04 turbo off here and going to be putting my 10.5 hotside off my 05 turbo on there. I see where alot of people strip the studs and bolts out. What do i need to look for so i dont do this or my buddy thats actually going to be doing the work. Any help would be appreciated thanks alot

Matt,


I have assited on the removal/installation in two diffrent ways:

1) dropping the turbo/manifold assembly
2) Without dropping the turbo assembly

Either way is tricky. For one, you will find rusty nuts on the o2 housing. If you decide not to remove the turbo assembly then be carefull with the radiator clearance.

Drop some special antirust oil to get the threads lubricated for a few hours prior to attemp the removal of the nuts.

Also, let the car cool down. Reroute the o2 sensor wire so that it does not get pinched anywhere. Get yourself a good o2 sensor socket. I also suggest putting some antirust/anticorrosive paste on the o2 sensors thread.

Last but not least take your time, it is a heck of a lot easier to do the removal and installtion slower and safer than breaking a nut on the o2 housing.

If you decide to drop the turbo assembly pay attention to the gasket for the oil retun line. Also pay attention when removing the header, it could scartch the top of the valve cover and also damage the radiator.

Good luck!

that was a good write up i really appreciate it any other opinions on this??? im also installing a manifold and 02 housing the same time.

 

just do the same as the write up on this forum. Buy some bolts that are the same as the studs, bolts are much easier to deal with. 10 mm x 1.25 pitch x 35 mm ....i think is the right size.

as soon as you try to reuse your studs, they will more than likely strip out and then leave you to do some re-threading.

long story short...use the write up and stainless / automotive grade bolts

 

soak the hell out of the studs and nuts with penetrating oil (not wd-40) the night before. Use the WD if you have no other choice but I would go with some aero-kroil or mouse-milk (which I am not even sure is available any more)

I stripped out one of mine and ended up just buyin the new hotside. I was able to repair the old one but didnt want to use it....also I wanted to change to the dual-flapper 10.5

 

wow this scares me going into it haha

 

I also broke one of the bolts holding the manifold to the hotside and ended up buying a new HS. I think it's pretty much the luck of the draw on if you will experience any difficulty removing it so best of luck.

 

looks like the car might go in thursday and pull everything off then friday put it all back on so i can have the bolts soaked

 

Not to sound rude, but why would you buy a 9.8 hotside to replace your stock 10.5 hotside? I know it is not that much more to buy a new 10.5 single flapper.

 

well my plans were to replace the 9.8 hotside with my 10.5 hotside that way i could avoid buying a new hotside when i already haev one!!!!

 

Oh sorry misread on my part. I read it fast, thinking you striped one of the studs on the hotside. I see now that it was where your outlet pipe bolts to the turbo....

 

yep no prob

 

yea the best way i think is the unbolt the dp, unbolt the manifold and all the lines to the turbo and pull the whole thing out. Also lubricate the bolts before all this. Buy new bolts and studs from your local dealer and once the whole thing is out unbolt the manifold and the o2 housing and all that stuff and put it all back on. BTW you will need more than one person to make it easier and it will take a few hours because youll come to a problem i garentee you.

 

when you say unbolt the manifold, do you mean unbolt the manifold from the block and pull the whole turbo up, or do you mean to unbolt the turbo from the manifold and drop the turbo down?

 

I would (and did) pull it up, exh mani and all. Put some cardboard over your radiator too to avoid damaging it.
