Thoughts on IC size for a stock turbo?

ETS only has 3" cores in stock and I was hoping to order a new IC this week.

I was planning to get a new ETS bundle which is there #1 package or some shit.

It comes with the intake, UICP, LICP and the FMIC, all of which I need to get my car running again and its a pretty good deal. ETS recommended to me to go 3.5" even though their 3" is rated at 700HP. They said the extra cooling will be necessary with the extra hot air I will be pushing with the stock turbo at 30psi+. To be honest, I am not sure the stock turbo will make 30psi on my setup as I think it will be maxed out but yea.

So I am struggling on whether to wait on ETS to get more 3.5/4" cores in stock or risk the 3".

Some people i have talked to said just stick with 3", less weight, plenty of cooling for 400whp and cheaper. Others have said you want the bigger IC's for more cooling and denser air etc etc.

I could look at getting a different IC besides the ETS to get a bigger one I guess, but I like simple and ordering a package deal from ETS seems simple and I wanted to do it this week so I can get my car running soon.

Also I have heard conflicting information on pressure drops and what not.
