Well, here is my plan for my AA stage 1 for my 325is
1)Get the Turbo rebuilt and have it thermal coated
a.Have the shaft lightened (this supposedly reduces a bit of turbo lag)
2)Have the exhaust manifold thermal coated
a.Also have the internals smoothed
3)Get a larger intercooler
a.Bar and plate design, 3 inlet and outlet (about the size of the AA stage 3)
b.Change over to 3 piping from the turbo to the throttle body
4)Go to a 3in down pipe with a 3 high flow catalytic converter, out to a 3 exhaust tip (no muffler)
5)Add an aquamist system to keep heat soak to a minimum
6)Get some chip tuning
Im hoping that this will net me more power and to run a safer higher boost level
I can't comment on that idea because I'm new to F.I. However, I'll be interested in the results because we have the same engine. When I went S/C, I was very happy with the results and thought that I was with the "pack" as far as HP. But now must people are talking about moving to 400, 500, 600 and even 900 HP......so you see, I feel like I have a 2 inch d--- when everyone else is packing a lot more
510 RWHP/ 485 RWTQ R.I.P.

None of that will really allow you to safely run a higher boost level, you need to drop the CR if you want to safely boost more....And the IC shouldn't be a high priority especially if you still only have the 16G stg1 turbo, You ought to be thinking of either building your engine, or swapping in a bigger one.....
If I could start over again, I would have built my engine first thing, but, I didn't so now it will have to wait....

Trash that little turbo step it up t3/t4 ball bearing 18g or 20g tight housing for quicker spool up, also install an external wastegate for percise boost. You can make power larger injectors 440cc and a larger hfm AA has Porsche twin turbo upgrade hfm that will adapt to what you have. Have AA send you a chip to get started because its all in the program. Maybe Nick G can burn you a chip. AA tuning is rich more on the safe side. You can also install a Super AFC 2 from Apex to tune Afr. I would also install an Msd ignition and convert it to wasted spark, regap the plugs .25-.28 Denso Iridium Ik22. Good luck
drop an ls1 in there for half the price
