Iwg works, but it can be prone to boost creep on smaller turbos with engines that pump a lot of air. Ewg always allows better boost control. Boosting the 7at has its own issues which have been well documented at this point.

I have looked into it and I am going to purchase a boost controller for the same reason but just wanted to clear that out from experience turbo users.

A boost controller will have no effect on boost creep. That's a mechanical issue. No guarantee it'll happen, but its possible.

Downside is the extra cost to keep the 7AT alive.

Just make sure that you get a transmission cooler and either the Transgo or GTM valve body upgrades and you should be fine.

Correct.

I would also suggest that anyone who is going with a much larger exhaust, ie. 3" would probably be more prone to boost creep with IWG's. I haven't run a search but has there been much of a history of boost creep with 370Z/G37 TT installs? I don't remember seeing mention of it.

OP, make sure that you install a good boost gauge and set alarms. If you find that the boost is creeping consistently then you can look at either porting or swapping to EWG.

I have a feeling that once everyone starts their GTM installs and run them for a few months, we will start to see what issues are common across the setups. If 50 kits are installed then we should have several thousand miles worth of 'real world' testing done within just a few weeks. :tup:

There's not a history of boost creep, but the 16g is the smallest turbo I've heard of being used so far.

Glad I chose to go with the 18G then! :happydance:

Yea I went with the 18Gs for the same reason haha, but yes I already have a Tranny cooler, VB, and workin on getting my gauges to have prepped before I get my kit...and yes I didn't go 3" on my exhaust seeing as you still get pretty solid numbers with 2.5" :D But thx for the info guys I just have a quick question though, have any of yall looked into Zeitronix Dash Daq XL?? Or should I stick to regular Gauges?

I was just going to go regular but I saw a parrot system on here with a GTR your load out.

Anyone know the turbo size the gtr?

Copied from GTRlife

I had no idea it was a pair of 2006 Sti turbos. That's kinda cool.

That is crazy I thought they would be a Garrett type or something.

Isn't the hot side cast into the manifold?
