The Teg's have hundreds of kits to choose from the best ones I've heard of come from GReddy, Edelbrock, Turbonetics, Top Fuel, and South Florida Performance (SFP).A T04 turbo is common place, very reliable turbo. Intercooler wise ARC, GReddy, PWR are pretty good.As for ECU's HKS & AEM.Kits are always better though because they were built to specific tolerances. Not to mention that you need to reinforce your block also.
