Sti Tmic???

Hey guys, I'm looking to upgrade my turbo to the vf39 or vf43 and I was also looking at getting a new IC. I know it's not a necessity, but should I get the STI Top Mount for $265 or should I go with something else? Give me your opinions! Thanks!

Running the STI turbo with the STI TMIC would be fine, especially depending on the EM you are using. For that price thats not too bad. Unless you can find a bigger/"better" one (i.e APS, Perrin) for that priced new or used would be the only other way I would go.

I think flow rates and pressure drops are the most important factors to consider when shopping for an upgraded TMIC. Just make sure it will more than fit your application because you definitely don't want to pay good money for one only to find out that it would be your limiting factor (as far as power is concerned). I'd suggest going a little bigger than you think you'll need - or a lot if you think you'll ever do any major upgrades in the future. You could probably even use the biggest TMIC you could possibly find and it wouldn't hurt (except maybe your wallet) but just remember, more surface area = more cooling power & shorter pipes than an FMIC would require = less lag = good stuff

A STi TMIC is fine with a 16G..... Just wrap your DP and get the 16G coated and bagged.

You can run a 20G with a TMIC, seen it several times. Just control as much as the heat soak as possible.

wouldnt having a FMIC eliminate the problem of heat soak and leave room to upgrade to a larger turbo?

as said before wrap your downpipe, putting a turbo blanket on isn't necessary unless your running a much larger turbo that can put off much more heat but it can never hurt either. As far as heat soaking your intercooler, make sure you have a heat shield over your turbo.

I know as far as "growing" or putting a bigger turbo isnt in my books. I will get one, and either be happy or deal with the fact I didnt get the right one the first time. But as Reno said, take the necessary steps to "protecting" agains the heat and things should be fine.

is it possible to modify the stock turbo heat shield to fit an aftermarket one?

Yep. Get a set of tin snips or dremel tool or some other kind of cutting device and cut it until it fits. It's just a piece of metal, so it can be molded into any shape you want. I think there are even a few diagrams out there of exactly how to cut the stock turbo heat shield so it will be compatible with an aftermarket bellmouth downpipe. Here's a pic of how one guy cut his. You could roughly follow that or just keep test fitting it and cut little bits until it fits. Or you could save yourself the trouble and buy a Cobb or SPT turbo heat shield
