They are CT12s. Trust me, if you have ever attempted taking them off, you would NOT want to put a bigger set on there. Say it with me guys "JUST GO SINGLE"

they're not t3 or t4,they have 3-bolt ct flange and no garrett turbo is bolt-on,best way to modify it ,is to put single turbo and tubular headers

it's a lot of work, after fighting with it for hours i just pulled my engine. the manifolds would be hard to modify. A adapter plate would push the turbos out far but with lots of welding and money it could be done.
a single kit would be about the same money and work better

Dont know about spinner but I have a budget+single=no time soon. I was looking into having them upgraded and rebuilt or CT12B heard their a PITA but its light modification. Even if I did go single I couldnt afford the turbo I want car is a daily. If I do I it I have about 5 days to do it in the street before alt. side takes effect.

There is a writeup on how to do the ct12 to ct20 conversion on SF, and a little more information on it here.

I had to buy some ratchet wrenches, all the intake pipes. i had to fit everything then tighten all the bolts to get it all lined up right.
