Hello All, it's TurboKits.com here to gauge the interest in a Forced Induction set up on the 3.8 Coupe?

Single? Twin? Price Range? HP?

What is everyone wanting?

Recap of info:

Quick teaser pic of the turbo we are using... We should be able to post some better progress pictures by the end of the week, beginning of next. It is coming along great!

Stay tuned!

Update - We have baselined the GC3.8. We'll keep everyone updated as the build progresses!

Thanks
Here are the pics of the kit we are working on. We are waiting for a few custom machined pieces to come back from the machine shop and we'll be able to move onto the next step... What do you all think?













Here are some finished pics from other projects so you can get an idea of what the final product will look like :)







That's all for now, we'll update the board as thing progress.

Thanks

I typically hate getting into the WHP argument. DYNOs vary, conditions vary, etc... For example, we have a Mustang DYNO, which is considered a "low reading" DYNO. The Gen Coupe ran only 242/237 to the wheels with a full CAT Back exhaust. That equates to a 25% driveline loss (242WHP/.75 = 322 | 306HP+15HP = 321). We just ran the car today, to get a baseline on our DYNO. Because I know the inevitable battle between SFR & BTRcc results will come up and I wanted to have a solid baseline before BTRcc tuned it. So here it is 395/374 @ 8.5 PSI on our Mustang DYNO. Yes, that is lower than what SFRs DYNO reads. That is typical with Mustangs they can read 5-10% lower than other DYNOs. So do the math, add back the loss and we are back inline. Which I also want to remind you, IF we do say 380WHP on our Mustang DYNO as a conservative tune w/ BTRcc, that may very well be 400+ on another DYNO. The proof of results will be in the gain. What you started at and what you ended at on the same DYNO.

Start = 242/237
End = (Currently) 395/374 to the Wheels - add 25% driveline loss back that equals 526/498 at the Crank
End = (Conservatively) 380/360 to the Wheel - 25% loss back = 506/480 at the Crank

Those numbers are well within the 100 - 150 WHP + TQ gain that is typical with V6 NA to Turbo conversions and well over what an out of the box kit will do on a 350Z/G35. Not to mention what was overwhelmingly asked for in our poll at the top of this thread.

Anyway, Battle on, just my $.02

Plus a quote from Jay at SFR about the kit's driving characteristics.

There is almost no lag and TurboKits.com did a great job choosing the turbo for this car. It can be daily driven without any problems. Gas mileage seems to be pretty good, too. Of course, do not expect something like stock mpg but after 50+ WOT runs on the dyno it only sucked up 1/4 tank of gas. We've tuned the car to run just like factory AFR while it's not in the boost ...So gas mileage should be OK considering it has aftermarket bigger injectors.

Twin. Price $10! :D Hp: +12000whp!!

On a serious note, Single and Twin would be nice. Price range for single about 7k. HP, maybe 100+ whp unless u start upgrading internals.

I would prefer a single turbo. The the turbo kit should be reliable and a good bang for the buck .

Poll added, thanks

Currently, it seems most kits being built out there are "show" kits. Big twin set-up costs upward of 10k$. The 3.8 is craving for more "down to earth" options, single modern turbo...

As much as we love the show, our goals will be a kit that can be boxed and shipped globally :)

Don't get me wrong, it doesn't mean it will not be a great looking and performing kit, but our HP goals will be realistic, the install will be as simple as possible and the price will be attainable by most enthusiasts... Deal?

^^ I second this. If I had another 10K laying around I would own a different car.

That's hard to know until you blow one up... Typically 50% gain in HP is fairly easy on most stock motors. I would bet a well designed and tuned kit at 8 PSI would put down 125 - 150 additional HP and be plenty safe on the stock motor.

I wonder if the 3.8 can handle both options. How much power before it needs engine work?

All depend about the final price! single or twin turbo vs SC! What kind of modification we can do before touching the inside of the engine! How much lbs the block could accept and so on!

It was clear, before I put anything on my car, it need to me safe to drive (without always to be at the garage for adjustment or reparation) and can be do long drive like is possible today!

i voted for single turbo bolt on, but what would be the advantage of a twin? If both kits are going to be putting out the same power? Will one spool quicker? more efficient at cruise?

Poll added, thanks
see look at the output you have gotten so far and i know i have a 2.0t but i would go with the twin but for no more then 3k and 100hp and i say this because for the 2.0 we have kits that will give you 100hp a atp turbo for 1200 and thats why i say 3k

No advantage if you are keeping the motor stock and around 400 hp
The gt35 is the best option for a single turbo for the v6.
You will get positive manifold pressure at around 1800 rpm and full 8 psi at around 2900 rpm.
Your effective compression ratio will be around 16.1 which is very conservative when putting a turbo on a NA car, 18.1 is still safe to give you an idea.With this setup you should hit about 370 whp.

I would rather s/c over t/c, but if I were to t/c I would prefer a twin turbo set up with 1 quick spooling small/medium turbo and 1 slower spooling medium/large turbo to pick up where the smaller one maxes out.
