I might have missed it but are you running some type of piggy back fuel computer or is it all on the stock Aristo ECU? If so, how does it run?

Nice outcome on the swap. Make sure you post more pic of the GS on the ground and the FMIC.

No piggy back or anything. All stock swap other than a FMIC, and a full 3in exhaust with a 2.5 inch restrictor in the middle. Need some back pressure so I dont over boost. I can only work on the car on the weekends so I have some fab and fitting to get done before I take the care off of the jack stands. But I will get pictures of the FMIC and other little things I do. Hopefully I can take her on a test drive this weekend!!

All I have to say right now is wow!! The swap drives and feels soooo smooth! It's a little weird being an automatic but, I'll get used to it! I like how I can constantly hear the turbos spooling up!! I haven't really got on it yet but I'll tell you one thing, it got up to 80mph really quick!! I still have a few things to finish up on it. But once it's set up right I'll get some more pictures up.

You get the random revving to 3500 problem solved? If so what was the issue.

Congrats, your gonna love it. Keep an eye on the heater core connections as the motor can move quite a bit and since it's so close just check for any signs of rubbing.

If you have an open element filter and aren't using the stock airbox the turbo's can be heard quite well. I give it 30 days and your gonna want more power!

The 3500 rpm issue is some what intermittent, it only happens every so often. When it does happen I just shut off right away and restart. It does it once or twice in a row when it does happen and then quits. Hopefully its something that will go away......lol yea right. As for the heater core lines, I actually decided not to hook them up. I just recirculated the line back to the engine. I saw how it was going to rub and decided I didn't want a mess or to loose all my coolant on the highway. I will come up with a plan before the fall when ill need the heater to work. As for the more power its too late. I already want it. I got on it today for a bit and enjoyed it quiet a bit. I can totally see the potential for more power! Im going to have to start my reading on going single turbo now. Id like to get one that will give me more power than the twins and with out having to change out the injectors or up grading the fuel pump. So far Im not having the fuel gauge issue with the Aristo fuel pump assembly. Ill keep everyone updated on that.

I do have a couple of small issues. The first issue is, when shifting from park to drive or drive to any gear, the transmission shifts kind of hard. Any ideas? The second issue is, when getting on the gas the car kind of sputters a bit. Not too hard but kind of annoying. I had a similar issue with my SR once. Id romp on the gas and the car would sputter at a certain RPM. After some trouble shooting I found out it was one of my coil packs. ??? Maybe I should order some new ones. Any Ideas?

Oh and one more thing, As for something rubbing, The rear turbo rests right on a wire bundle on the fire wall. I tried to shift the bundle up and it didn't move at all. Theres no play in it. Has anyone had any issues with this that you might have heard of? I can see this possibly being an issue in the future. BUT not if I go single!

I've learned a lot in this thread. Really gives me a heads up on what I'll be running into when I do my swap.
