Looking for some thoughts here. I have my eye on a performance exhaust - but before I invest - i am looking for confirmation. In what order should I look to add performance mods? Mostly a weekend street car - but about 5-6 DE events each year. It's an unmodified TT with about 16k miles.

Exhaust
Software (will be calling tony)
Turbos - K16s billet I assume
SSK
New clutch needed?
Anything else?

Does that order make sense? Thanks for any thoughts!

 

I would add a good set of intercoolers like ETS to the list.



Pm me for pricing!

 

Do you have any data on your IC's? Are they better than the 997.2 ones?

 

That is not a bad way to go. If you have already decided to do turbos, you might skip the flash with stock turbo step and go straight to upgraded turbos. You will need a better clutch after a while with flash+exhaust. I would go for one that will cover more power than you plan to ever put in the car so you only have to do it once!

 

ETS has not released any data logs yet - I will ask them about it in the morning!

 

I would definitely go for an upgraded suspension and brakes. Both of which are far more important than the engine upgrades for track work.

No doubt about that for the track... I should have clarified that I was looking for more HP! (Seat of the pants fun)!

 

I actually thought about starting w the turbos - but I suppose that would be dumb without the exhaust first... It seems that regardless - exhaust is probably first.

 

I would go with flash before exhaust. Unless you're preferring better sound, you'll get more of an HP gain that you'll feel with the flash -- especially with the 996TT. I'd also do the SSK earlier (it's relatively cheap) as it will greatly enhance your shifting experience.

 

Agreed! Do the flash first. It is the best intitial bang for the buck. After awhile add the exhaust. SSK was my third mod as well.

 

I think if you do flash before exhaust, won't you need to flash it again after adding the exhaust, right? Or does the tune automatically adjust for the more free flowing exhaust?

 

No need to retune.

 

I went with the 992 GT2 coolers, they made a huge difference. It dropped my IAT by 25+ degrees on a run on the dyno in the same conditions, the car picked up 40 kw through the mid range.

It also dropped the IAT on the strip by a huge amount as well, they are the real deal.

 

An exhaust and flash in combination have the most fun factor as feel them in everyday driving. Instant gradification at the push of a pedal. If you plan to modify for power beyond this, then give serious thoughts to your end goal. Changing turbo's opens a whole can of worm or opportunities depending on your view of thing (and your budget). Intercoolers, fuel rails, injectors, FPR, and fuel rails need to be considered depending on which turbo's you pick. The flash you did for just the exhaust will be not be able to optimize these other mods. So you'll have to pay for another flash (or upgrade of the one you have) if you don't do all the mods at the same time. With higher power output goals, you'll also need to consider a stronger clutch assembly.

The thing you didn't mention is suspension which is unfortunately usually overlooked. The stock 996tt suspension in US form is not tuned to match the stock power. What saves most people from disaster is the AWD and substantial understeer PCNA has dailed into the car. By way of example the GT2 (also known as the widow maker) with the same engine (X50 version) has a substantially different suspension including relocation of the suspension pick up points and 2wd.

I would invest some money in suspension modifications depending on your intended use. For a street only car you don't need to get too radical. The factory X73 suspension is the safest bet as it has been through all the factory testing and you know it will work as designed. PSS10 are very nice for the street due to the adjustability and if you don't drop the car too far you won't need additional suspension components. A thicker rear sway bar is alway a help with an alignment to reduce understeer. If you intend to track the car more than occationally you can get into some seriously expensive mods.

The stock brakes are fine for everyday use but if you plan to do much track time these will at least need harder pads and better brake fluid. PCCB are fine of the street but not suited for track use.

The drive train and shifter have too much slack in them which is easily corrected using stock parts. (replace with a 997 short shifter, 964RS motor mounts and a 997 tranny mount). These are easy DIY's. Less than a days work and you don't reduce the comfort level of you car like most other mods will.

Lastly the most over looked mod is DE events. It is amazing how much faster your car will go better educated and more seat time the driver has.

The point is to try to achieve balance with the car in suspension, braking, and power. Remember anything you do to increase performance will most likely decrease comfort.

 

Thanks for the information guys as TEXECH stated the exact questions I have for my list of performance items.

Can you please clarify that a clutch upgrade is needed with a ECU flash and mild exhaust upgrade - street application only?

TEXECH - where are you getting the ECU flash and why did you choose them? I am looking myself. Thanks.
