Im parting out my other car and Im trying to decide if I should keep my turbo to use on my truck. Ive got an 03 SSS, all stock internals and planning on keeping it that way for a while. I think Im just gonna run around 10psi with a top-mount intercooled setup. The turbo I have is a Precision SC61 52E, .60 compressor housing and .63 exhaust side. The only problems are that it has a T3 flange and most of the manifolds I see are T4, and it has a 5-bolt exhaust outlet which will be a pita to make a DP for. Nevermind I think they make a V-band adapter for it I could get. Its rated for about 650 hp which is more than enough and it cost like $1000 so I dont want to sell it and lose money when I could use it... Well here it is:

 

That looks like a GN turbo. IMO that is way to small for a 6.0l. You would bo better off with a STS kit or one of KB's and a T4 or Tricks. Minimun A/R on the exhaust side of .96. IMO.

 

Too small. That A/R alone is gonna choke you down...ask me how I know!

 

Alright I kinda figured that but I wanted to be sure. Thanks-- One more thing- is my Tial 38mm wastegate big enough if I run 10psi?

 

You might give Precision a call the exhaust a/r is easy to change. But Precision units are alot more then just sizes. They have different fin designs for deferend boost pressures. Some turbos are for small engines lots of boost others for larger engines and low boost.

The gate is fine no need to change that at all..

that does look like a baby GN turbo. a 76mm is good size for your 6litre

 

yea too small, im running a pt70gts 70mm on my 6.0l and runs really strong, pulls hard on top and comes in really quick

 

Ok cool thanks for all the help, Im just gonna try to sell this one and get a bigger one when its time to put it all together.
