Cartuning Performance 3800 Turbo Kit



3800 Performance is very excited to introduce the Cartuning Performance 3800 Turbo Kit, the first turbo kit on the market for the 3800 powered vehicles. We are currently offering this kit on a pre-order basis, with the expectation of first orders shipping to customers by 8/1/04.

We are taking pre-orders for the 1997–2003 naturally-aspirated 3800 L36 Grand Prix GT and Buick Regal LS models. Additional naturally-aspirated vehicles to follow in the near future are the Impala, Monte Carlo, and the V6 Camaro and Firebird.

The Cartuning Performance 3800 Turbo Kit has been in the works for the past 18 months, being extensively researched, developed, tested, and tuned. This kit wasn't just thrown together, and it shows! The kits come COMPLETE with everything needed, with expected installation time of less than 6 hours. The vehicle does not get modified in any way that does not allow it to go back to completely stock. All factory parts remain perfectly in tact with no cutting or modifications to the drivetrain or exhaust!

Now what everyone is wanting to know... on a completely stock L36 vehicle (which makes 160 HP on the dyno, 200 HP to the crank), the Cartuning Performance Stage 1 Turbo Kit makes 280 HP to the wheels and over 300 lb-ft of torque to the wheels. That is 350 HP to the crank, which is a 150 HP gain over stock!! How's that for one day's worth of work? The Stage 1 Kit is completely streetable, and is suitable for customers that want to bolt-on a turbo kit to a stock L36 vehicle that has little to no modifications and wants an exciting daily driver without having to modify it for months and months (sometime years!) only to get minimal performance gains. The Stage 1's turbo is good for up to 425 crank HP with additional supportive mods.


This is only the beginning though...

- For those needing more, you can upgrade the Stage 1 turbo to a custom-built Precision Turbo unit, which is capable of producing up to 700 crank HP!!

- A Stage 2 Kit is also being developed, for those customers that want to take their vehicles much further in the future, or that already have numerous mods that support more breathing. The stage 2 is currently being tested, but yet to be dyno tested. More info is forthcoming.

- Coming VERY soon is an adaptor plate to make the Turbo Kit work perfectly on a supercharged L67 Grand Prix GTP and Regal GS.

- Also coming soon is add-on front mount intercooler kit which will be a direct bolt on.


List of Components:


The Cartuning Performance 3800 Turbo Kit can be pre-ordered for $2999.99. The advantage of pre-ordering is that it locks you in at this pricepoint and places your name on the waiting list. Each customer who purchases this kit will be personally contacted to get details of the specific model and year of your vehicle, and what mods you may already have.

For any questions you may have related to the turbo kit, please email turbos@3800performance.com to get all the specific details answered.



NEWLY ADDED UPDATES!!

We have been getting several emails each day asking to see more images of the Cartuning Performance 3800 Turbo Kit, so we have created a "Media Page" of all the pictures, dyno graphs, and drag strip videos. Click here.


Frequently Asked Questions about the Cartuning Performance 3800 Turbo Kit
- written by Kevin Margitta, owner of Cartuning Performance

Q: What about headers? Why does your kit only use stock manifolds, and what should I do with headers I already own?

A: This seems to be the most popular question as of yet. Interestingly enough, the stock manifolds can support enough horsepower and torque to stress the limits of your powertrain beyond that which most people would like. If you could make 600 crank HP with stock manifolds, you’ll be more worried about the transmission, axles, pistons, etc. After extensive research, we decided that having the factory cast manifolds provides a very reliable setup (expansion and contraction of tubular headers on a turbo setup is quite stressful to the metal) while supporting enough horsepower and torque to satisfy just about anyone’s needs. Add an intercooler, cam, heads, etc… and most people won’t be trying to make more HP, but rather keep the transmission reliable as a daily driver. Also, by the time you are reaching the 500’s in HP, you are testing the limits that your stock bottom end, pistons, etc. can withstand. Already own headers? Well you could always sell them and recover some money to offset part of the cost of the kit. Most people who have headers, still retain their factory manifolds. If you have sold yours, then make a deal with the person wanting to buy your headers and buy their manifolds from them. Or even better, purchase WPI Ported Exhaust Manifolds, which will be available very soon. Our custom crossover pipe is not a modified factory piece, but made from scratch (mandrel bend) 304 stainless “Y” pipe which eliminates cross pulse issues, and directs exhaust gas to the turbo very accurately.


Q: Doesn’t a turbo kit NEED an intercooler? Is it safe to run your Stage 1 Kit without one?

A: Here is a very interesting question. If you have a kit which comes with say, a fuel pressure riser and no PCM tuning whatsoever, then I’d say the kit was unsafe for the engine with OR without an intercooler. However if the kit was designed properly, like ours has been, and the PCM was tuned for all the changes made, like we provide in the kit, then it’s perfectly safe. A turbo outputs air much cooler than the stock M90 Eaton supercharger does from GM. I don’t recall the factory giving you an intercooler! We’ve tuned the car to use 91 octane, and have allowed for 15 degrees of WOT ignition timing, along with many other fueling and transmission changes and see absolutely 0 degrees of knock retard. The Stage 1 Kit is perfectly safe to use without an intercooler. The addition of our forthcoming Intercooler Add-On Kit will allow you run additional boost, additional ignition timing, or a combination of the two, resulting in much more horsepower.


Q: What about camshaft selection, and can I use my SC or NA cam with this turbo kit?

A: The answer here is that a turbo cam is quite different from a SC cam. In general, any aftermarket camshaft for a SC or NA application will not work well with a turbo installed on the vehicle. Having said that, any factory cam will work considerably well (as our dyno numbers have proved), but of course a future upgrade to a turbo spec cam will certainly help the breathing of a turbo'ed engine. We will be working with 3800 Performance and Comp Cams to come up with a turbo cam that will match our current and future turbo kits.
