Blew my turbo on the way back from SoCal. Rather than buy a replacement turbo, I figured it's time for an upgrade.

 

So I did some research and bought the ISR(formerly know as ISIS) Performance RS3871.

 

I'm planning on doing a top mount set up and haven't seen any info on what will and what 

 

won't work fitment wise. Is it their any issues that I need to worry about?

 

I've seen photos of top mount set ups on the interwebs so I am just

 

hoping is super easy and all I have to do is buy the top mount manifold

 

and the supporting mods. 

 

BTW: these are the turbo specs

 

Compressor side 3" inlet 
Exhaust side 0.64 A/R turbine housing, Results:
This turbo is rated up to ~380hp.

@speedtech what do you mean by "space up the motor a bit"?

He means the motor had to physically be raised due to wastegate interference with the steering column. I ran into the same issue with a sr20 bottom mount setup. The steering column was going directly through where the turbo sits. So I had to go top mount Everything else is being fabbed up, so it'll be a custom fit for me.

I am running a top mount but I am about to switch to a front mount turbo right in front of the steering rack
