Of course GReddy doesn't make a piping kit that is specifically designed to fit with the ARC SMIC. There are many ICs out there and GReddy certainly doesn't have time or interest to make piping kits for them or test if one of their existing piping kits fits (and then be responsible if the end user has trouble). One of their kits might fit just fine, or perhaps with a little modification. But expecting them to have something specific is not very reasonable.

For the intake, cut the back out of the intake box and replace it with one that has a connection the same size as the T78 compressor inlet. You don't want to choke the turbo with a small diameter intake pipe.

Just a suggestion, the greddy and arc stock mounts are way too small for a single turbo.

Agreed, the smallish ARC SMIC isn't even big enough for running decent boost on the twins, let alone a T-78...

The regular ARC SMIC is SMALL, not much bigger than stock. You can most certainly run an SMIC with a single, just not one as small as the ARC regular model.

here are the specs ont he reg ARC IC

H 260 X ------ INCH 10

L 500 X------- INCH 19

W 70 X------- INCH 2.7

NOW THE RACE VERSION IS SUPPOSE TO ALOT MOR BEFFY SO AGAIN WTIH TECHNOLGY AND WITH THE MAJORITY OF JAPN RACER USE ARC COULD THIS WORK, AND I WAS TOLD THAT THE STOCK LOCATION WAS A REALLY GOOD PLACE TO BE IF YOU CAN GET THE AIR TO IT BY OPENNING UP THE DUCTING I DONT KNOW I COULD BE WRONG

The regular ARC SMIC does NOT have a 19" wide core, I'd put money down on that. ARC makes FMICs too and those dimensions make a lot more sense as an FMIC.

So, are any of the dimensions you posted correct for the race version of the SMIC (if such an IC does indeed exist)? 12" across sounds VERY much like a nearly-stock sized SMIC. Do you have a picture of the IC?

For less money and better results, you could get a GReddy FMIC with piping that mates right up to the T78. If you are intent on using an SMIC, the ASP units are the best available anywhere, though they might not fit with the ARC intake. And like any non-GReddy IC, you will need custom piping to match up with the T78 (or at least you will need to take responsibility for finding some pipes that work -- no one is going to sell you a T78 piping kit for their IC except for GReddy).

You should try and get the size of the actually ic core...not the entire ic. The core is what really matters. It needs to have at least a 10x10x3 core if your going to run a single with it.
