Think I'm ready to finally pull the trigger. Car currently has upgraded clutch, Kline 2.5" exhaust, umw tune. Has had new oem fuel pump put on as well in last 18 months.

I'd like to get around 600 Hp. Car will be mainly street driven. I know I'll also need to do injectors.

What's everyone's recommendation these days? I had been looking at Sam's 1668's. Not sure if there are better options now for bang for the buck.

Kevin's stuff to get to 600 hp is the way I'd go.

I have Sam's 1668 turbo along with his mafless tune and a slew of other goodies. My estimate is I'm somewhere between 600-700 crank hp. Kevin's work speaks for itself as does Sam's. My feedback on the 1668 turbos is that while they get wheezy at the very top end, they react like a v8. Anything above 2200 rpm and there's plenty of power on-tap, great for squeezing the throttle a bit to make a quick pass.


I should add, I run the Siemens 60lb injectors because they came with the car and my fuel rails were already modified so when I did the turbos I just sent them off to be cleaned/calibrated. If I were to do injectors from stock today I'd go Cobb/ID 1000 or ID 1050 if you couldn't find the ID1000 anymore.

As much as I like Sam I think even he would tell you there is value in sticking with a single tuner IF you already have a good working relationship with them. These packages (Marski, Todd @ promotive, Kevin @ UMW, Sam @ ByDesign) all work as an ecosystem. An apple iphone works better with a mac computer than a windows PC.

My experience with UMW has been great and was based on what I'd researched here for a long term reliable scenario. Powdrhounds info got me started and after working with Kevin the past 3 years I've been very happy to get his help in other areas as a customer. This has saved me lots of time and $ that is really unquantifiable but clear once you're into these cars.

I recommended Kevin since the OP already had a UMW tune, and because IMO Kevin builds great turbochargers.

Yep, i'm open to sticking with kevin, and sam's also been a solid asset for me. Fully understand if I go away from kevin i'm ultimately losing the UMW tune, which isn't a huge negative. Whomever I buy from will require a new tune so that's in the equation for me.

I just want to say here that we are lucky to have excellent choices in mod guidance. Can't go wrong with Kevin or Sam.

I love my K24/18s. I know not the newest and hottest stuff, but really, and I mean really gets the job done.

Where in the powerband and how much power are the things a good tuner can manage for you. My desire for big block feel on a track with some low speed corners to keep up with others was exceeded with Kevin's ZC turbos. Before, a C6 Z06 would walk away from 40mph, about 80 I'd be gaining, and into braking close the gap. Now there's no gap

make sure you know what your goal is and do it once. i have k16 bases billet and hate the fact that it falls off around 5 to 5.5k or so. it hits strong low but you really end up short shifting....in my case should have gone k24 based billet

Whose tune do you have?
