I ran a search and was surprised not to find a thread addressing this.

I am trying to decide on my next mod: 1. upgraded turbos or 2. upgraded ICs.

current mods are softronic flash and sport exhaust system. I know it would be best to do both turbos and IC at the same time, but i cant financially swing that.

Any advice on which to do first?

 

IC's

 

I would certainly upgrade your intercoolers prior to swapping out the turbochargers.

Definitely ICs especially if you plan to upgrade your turbos down the road.

 

would logging the iats in typical driving tell you if you were pushing the limits of the stock intercoolers?
I was on the SPI website and their SPI 650 kit has upgraded vtgs but i/c aren't part of the kits until the
next level up.

 

Depends on how you define "typical" driving...lol.

 

ha, that's true. I guess I'm just wondering if the datalog can tell you if the
i/cs are the bottleneck?

 

why ICs before turbos? i am really confused about this.
also, i am trying to decide on who locally to use to work on my car. I've narrowed it down to two guys, problem is that one of them recommends to do IC first, other guy says to do turbos first.

 

Easy decision. I would not use the one who recommends turbos first.

 

You wouldn't benefit new turbos unless you do upgraded IC's. The ECU will pull back timing because of the extra heat that new turbos produce, so you won't get the power advantage of the new turbos. By doing IC's first, you can now run 'safer' and a little bit faster especially on these hot summer days, and whenever you do the turbo upgrade, you could fully take advantage of it.

 

How bout a $300 Water/Meth kit instead of IC's. I ran one in my old car with an intercooler and the IAT's would drop when the pump came on

 

Thanks for the good info.

 

Besiktas is right I think...
My 997 is "only" VTG's upgraded with exhaust and headers, but it only really performs very soon in the morning... (lol)
I'm now making my choice for a pair of Ic's, all shows me the Ic's are the "key" to really obtain performance with a 997TT. (or any turboed engine...)
More, I noticed the stock 997TT Ic's seem to be really quickly heat soaked.

 

ic's without a dout!!!!

 

A properly designed IC setup should cool IATs without the hassle of installing an aftermarket spray system.
