people that have swapped turbos...what would you do different?
If you want to be fast on a Road Racing track (in my area, that would be BIR, Road America, etc), I would stay with a K-16 based turbo. The K24/18g's that I had were pretty severe when leaving tight corners, etc. If you are a highway hero (which gets old) then you want the biggest, highest flowing turbos (whatever those are today, like the K24/20g's as an example) Those I believe are one of the few turbos that have hit 200mph in the Texas Mile. The handling mods and brake mods, really make a difference on these cars that are really too heavy to be a serious track car. They are so capable in a variety of areas though.
pick the proper tuner and engine builder the first time. conservatively i have wasted 15k$ on stuff that either didn't work, broke or just sucked. find a proper builder , tuner and listen to what they have to say. build it once and leave it alone. ( could have saved thousands if i just kept my own hands off the car! but i can't leave well enough alone)

When I had my 18g setup I was still running stock ic. I had to let the car cool down in between pulls due to heat soak. It's hard to quantify the heat soak but there was a significant difference in power. So to answer your question, yes you need ic when you upgrade your turbos.
Tuning Options
For all those located in Colorado, I own a German tuning shop and would love some 996tt business! My shop is ABS Motorsports. If you look at our reviews, you'll see that you'll be hard pressed to find another tuning shop with better prices or better service. Sorry to solicate on this forum but we rely mostly on customer referrals instead of spending 5 bucks for every click someone makes on Google.
Anyway, like others have stated, it's EXTREMELY important to work with a tuner and let them know your goals. A tuner will have experience with different sized turbos, different engine setups and accommodating mods. Forums are great to get a rough idea but dealing with a tuning shop will help you pinpoint exactly what mods will be good for you depending on what type of driving you'll be doing, what levels of lag are acceptable and most importantly, what your budget is. Whenever you do a build, always allow for the unexpected. When you pull everything out of your car, you're bound to find more things that need attention that you didn't plan for.

If I was doing it all over again I would just buy a 997.1 GT3 RS and only do a few minor tweaks to it and have a bunch of extra cash in the bank from the money I saved by not moding a turbo. Yes the car would have been more but I would still be ahead over all and I would have a car that fits better with my road coarse track racer personality. I feel the 996 market has gone to a freeway roll on racer / ricer moding mind set which really makes me want to puke.

but wouldn't a modded & stripped down turbo give you the agility of a gt3 ( or close enough? ) with the added breakneck capability of the turbo's? i can see the difference and would like to be able to strip enough off the turbo to have just that. but i guess it'll never be a gt3 just like a plain ol turbo won't ever be a gt2rs. dammit.
i'm *almost* at the point psychologically where i can imagine myself beginning to physically tear out of the car the last of the creature comforts of the car and with it the last vestiges of both streetability as well as salability. one of those two is a word lol.
as it is, it would be a tough sell for anyone wanting to tool around town and i haven't been done much, let alone stuff thats irreversible.
i know from stock. i know from x50, and i know from 16/24's. just wish i had more seat time in an a28 car with supporting stuff or even those new turbos, whatever theyre called again alpha 3076 rotax'? rotors? whatever. lol. i bet i would like those too

Engine Guy did say with his driving preference (track time) that a GT3RS was the hot ticket.
For me ? I bought the turbo to be a GT car and ended up wanting more power and have now gotten into semi-silly territory . Yes, for the guys making 900-1000 bhp, to me that is silly territory
I was recently told my car in its current state is resembles a car that sounds "angry" and wants to be driven like that with belly button shaking hands with spinal cord on every WOT on gas pedal. To them I say its an addiction to turbo spooling.
To OP, somewhere up the top of this thread, do your research to what driving style you want to develop into, get a ride in some of our cars to see differences and keep notes, then do it all one time if budget allows and come back and tell us your experience.
