Thier FAQ is dated? It just came back up after being revised.Chucky Doll said:I'm running the HKS Type S FMIC. Very nice IC that will give you more power. MKIV tech data about sticking with the stock SMIC is dated. Don't get me wrong the factory IC is a good, but you will gain performance from a Type S or a Greddy 3 row IC.
Walser said:The Greddy sidemount is the only stock location replacement IC that I am aware of. Flow rates have been done with it, and it did no better than stock. The stock IC takes up all the 2D surface area in it's location. A deeper core IC adds heat-absorption at an increasingly less-effective rate. It's surface area that you want for most apps. The Greddy sidemount might be good for a road race car on stock turbos, but that's about it.
With a stock turbo car, a front mount IC will help, and turbo lag will be increased a little. But you will be faster. The info on mkiv.com is a little dated - that earlier recommendation was done with advice from a very small sample set. Back then, a 550 rwhp Supra was cutting edge. I think we have like 10 of those in this town alone now. A good IC is the Greddy 3-row: it provides good stock turbo charge cooling but can be retrofitted for big turbo duty. SW, Clint and I run that one in our cars.
