i am looking to change my houseing to a 16 cm housing i was wondering does it just bolt on with my impeller the houseing i am getting would be empty is it just the 4 bolts and slide it off or is there more involed with it i can get a houseing online 4 $150.00 is that a good price or is there a better place to find one

 

Yes, it is just 4 bolts. It won't just slide off, there will be a lot of hammering and cussing involved. $150 is fair for a new 16 cm housing.

 

thank you is there somthing to hit and something NOT when taking off

 

Only beat on the old turbine housing. Make sure that it comes off square or you'll destroy the turbine wheel. You will have to beat on it with big hammers for about 20 minutes before it starts moving.

You were planning to take the turbo off the truck, right?

 

does it really improve my truck going to a 16 cm or is it not worth it

 

yes thank you now i am

 

On a '93 it's not a real big deal. The 18.5 cm housing isn't that bad. If you want a dramatic change get a 12 cm wastegated housing off a 2nd gen, or even the whole turbo.

 

i was told that i have the 21 cm houseing because i have a auto trans is that wrong i dont know

 

It should be an 18.5 cm on your '93. To check, get a flashlight and a mirror and look on the back of the housing. If it's a 21 cm there will be a big "21" cast in it, if it's an 18.5, there will be an "18" cast in it.

 

where on the housing i have looked for it many times

 

It's on the side facing the firewall. You pretty much have to stand on your head to see it. A flashlight and a mirror help.

 

found it, it says 18.5 thanks much

 

4 bolts yes, but if they look like mine, it's going to be a BIG pain to get it off. From the looks on mine, I'll bet they all snap off and I'll have to drill them out.
Yuck.
