Thanks mate lot of research and hours gone in as always with modding. Just don't get carried away with hp numbers...Aussie vs US you'll be disappointed. Look more at the hardware and go from there. I am 99% track use and my setup is built around this.

MT are hard to find. Finding a clean one low ks will be hard.

 

headers are not worth it intake is not much improvement either but inlet hoses are a decent improvement.

exhaust, tune, inlet hoses k16 billets, billet diverters, and some intercoolers you'd have a quick car and alot of fun.

 

Welcome!

Second everything Saintly said.

I went with Kevin at UMW and I believe Saintly has as well in the past, can't say enough about him and his tune. My 996 runs his K16 housing zero clearance turbos and has better low down response and higher top end than stock. It traps 127 mph at WSID (Sydney Dragway) and put down 345kw at all 4 with the A/C on at the last dyno day at Advan in Sydney.

Good luck on finding a nice 996 and finding a tuning package for it! The fun begins! Where are you located? How much are you looking to spend and how quickly are you ready to move for a white/black manual 996TT?

 

I'm located in the Hills district.
I missed a very low km manual (yellow) 996tt recently that was for Sale in South Oz.
It was a private import from the UK (one owner) and it had been tuned.
It went for a bargain as the owner had to go urgently back to the UK ($65,000)
My budget is around $80 to $85,000 which won't get me a low km 996tt in the current market.
I have been keeping an eye on the 996tt market for several years and the prices have gradually been coming down to my affordability realms.
It wasn't too long ago when the cheapest 996 turbos were going for $120,000
I don't think the low end ones will drop too much further in price in the next 12 months.
My mortgage is close to being payed off and I told the wife a Porsche 996tt was inevitable.
My first drive of a 996tt was at the Porsche driving experience at Mt Cotton in 2002.
I knew after that day I had to have one.

 

Would you say that the inlet pipes could potentially increase turbo spool rate by 200 to 300rpm?

Can you upgrade the inlet pipes easily without dropping the engine?

 

The hardware in the US is much better value than Australia.
I have bought quite a few go fast bits from the states before and it all worked out pretty well.
I'm not overly keen to ship turbos and ECUs over to the states to get worked on though. It would be a nightmare if the parts went missing.
My preference is to get the best value parts from overseas and have a local workshop fit them then dyno tune the car.
I'm not chasing a specific HP readout however it always helps with bragging rights at the pub.
I'm more interested in improving overall drivability by increasing torque across a wider rev range, improving top end performance without creating lag, better grip and cornering performance and overall power down.
My friends 997 turbo has had about $25K spent on engine and suspension mods which is a lot more performance than what I need (initially )

 

yes it does help with spool.

it can be done without dropping the engine but you have to cut the stock inlet plenum to do so. it has been done by many but you cant return to stock unless you repurchased those parts.

i have a core inlet plenum if you need it to send to one of the vendors that makes the inlet pipes.

Sounds like a tricky upgrade with the engine in.
I think I would wait until the engine had to be dropped then do a few other mods as well like injectors and fuel rails etc.


Thanks for the offer for the parts too!

 

hey buddy,

I live on the Gold Coast

I have a Markski tuned 996T with k16 billets built in australia 911 tuning inlet pipes ipd plenum gemballa exhaust injectors 1 bar waste gates 3.5" coolers and heaps more. Over the years I have spent heaps, my car is very quick with maybe a little more to come which i really dont need in aussie with the go slow speed limits.

In my honest opinion and if I had the opportunity to do it again I would go with a Markski 911 tuning stage 4 if i got a car with k24's or a stage 3 if i got k16's plus injectors and a sachs clutch and gt2 clutch conversion just have the turbos built in aussie place on the Gold Coast did mine.

If you want to know more about what u getting into PM me and if u on the Gold Coast any time Im home Ill take you for a run and show u.

Cheers,
Tim

 

Awesome. Thanks Tim.
I wasn't really sure how the US tuners load programs into your ECU and wether they had 98 Octane Maps available.
All of my built cars have been dyno tuned with the factory ECU re-calibrated for the mods.
Do you plug your laptop into ECU and upload a new map?

 

The UMW website seems to be broken.
I haven't come across Zero clearance turbos before and am very interested in the concept.
I'll keep trying the website to see what Kevin offers.

 

He has never bothered to finish his website. His turbo's are great pieces of work. Your better off emailing or calling him when the time comes. I have all his hardware and I have zero complaints! Just my 2cents.

 

Tim, any power or performance figure's from your mods?

 

yes mate plug in laptop with a durametric cable and upload your protomotive tune

 

no not yet but its a lot 550+hp and 600+ torques atw I guess.

its a lot more than i had before which was 400hp and 640 torques atw i think my old dyno sheet is on my profile

after high flowing turbos fitting inlet pipes injectors and marks tune the car is insane
