Porsche Turbo Upgrade Help

[Marcone]

I have another new 944 turbo this time... Mint condition . I would like to Boost the hell out of it.. This is my first actual turbo for my self... the turbo S is no longer in my posession..

what are my quickest upgrades to make it a bolt on blast?!

This is a Doctor Driven Garaged Show piece... but i want it to have a stupid scary option when you push the pedal down...

P.s. i would search..but the search function makes my browser blow up every time i touch the button 'search'.... sorry

Realistic budget, horse power goals? Daily driver, weekend, track only?

All of these are important to making a decision.

BTW, another important thing to think about is what you want the powerband to be like. Do you care it comes on late but very hard but with an anemic off boost character or do you want a more linear powerband.

[Marcone]

I just want this car to be impressive... it will be a daily driver/ only summer time.
Hoping on 300 hp area
couple grand upgrade price if possible... once again money isnt the issue.. feasability is....

im getting a good deal.. i dont mind spending a few extra dollars.

P.s. I will be tracking the car too...

Look into getting a good wastegate, boost controller - MBC or EBC, a turbo suited for powerband conducive for street use and a set of chips to match. You'll also want to look into upgrading your exhaust.

I'm currently running a 50 trim standard bearing turbo in my car with the mods I've mentioned. I'm also still using the factory AFM and must say that the car performs well. In comparison to the k26/8 that was replaced, my setup pulls hard out of the hole and doesn't taper off at the upper revs.

The latest BB offerings from Garrett are definitely a cut above in terms of quicker spool time and transitional boost response, but they are a bit more pricey. A solid 300hp car at a reasonable budget is definitely attainable.

[Marcone]

Now, do turbo's come with chips to match? or is this buy a piece from one place then another from some where else..

will i end up having to buy new piping and things i see tons of extra pipes on these cars compared to my N/A cars...


Its a nice one eh?

[Techno Duck]

300whp is about the absolute limit of the stock K26/6 turbo, which is what i am assuming you have if its not a Turbo S. You can get to the 300bhp level with less than $1500 in parts. Pauerman has a good list there. A good wastegate (i suggest a Tial 38mm), manual boost controller, GOOD chips (tune is essential), 3.0Bar fuel pressure regulator and 3'' exhaust (with test pipe) will get you in that area assuming the engine is in good condition to begin with.

Anything more than that, you need to move to a larger turbo.

[Techno Duck]

Stay away from the generic Weltmeister, Autothroity chips. They are tuned for a very generic setup and do not offer good AFR's. Look around at Vitesse or the MaxHP chips. These can be tailor made to your setup to get your car tuned properly.

Intercooler pipes are not really necessary, but some claim better spool up, less boost leaks (which is true) and they look much nicer when painted / polished up.

[PAUERMAN]

Typically, when picking up a larger turbo you're obligated to pick up a new set of chips that are matched to the new flow specs. Some guys mix and match where they get their hardware and software from, but most vendors sell turbochargers with matching software as an option.

You'll be fine with the factory airbox and boost tubes. You'll need to modify your rubber J-boot by adding an adapter pipe if you plan on moving to a larger turbo though.

GREAT HELP guys!! thank you!

So around 1500 dollars and im in for a nice ride.. good...That is absolutely perfect!

so what about the extra 600 i had in my head for the job... (originally i assumed it would cost me around 2100 ish area... )
can i get to 350? 400? too much to upgrade then?
will that be able to be done Reliably.. or am i getting too cocky?

[Techno Duck]

300whp is the limit of the stock turbo. From there you can consider picking up a MAF which will further improve spool up and maybe marginally help with power. Personally i would look into suspension, or just saving it for maitenance.

If your looking for 350 - 400whp, its time to start looking for a bigger turbo and injectors.

[Marcone]

I have a track suspension that is ready to be put in.. bilstein gold cup or something.. with coilovers on the back ...

i didnt save the money for the job.. i have money to make this a nice little mover.. lol..

so... bigger turbo .. will mean what else bigger? will that need other parts to re-enforce the larger turbo.. or is it straight exchange one turbo for the other.. and a few chips?

what does a bigger turbo go for? and what is needed in that area?

If not ill just stick with the 1500 dollar step up. but i dont mind spending 2500 area if it can include the bigger turbo setup .

Take a look in the turbo section.

If it were me and I was doing it I would.

1) get a bigger turbo (Pm me if you want more info) May possibly need a new crossover or mod one along with a downpipe
2) get chips for 20 psi form Russell
3) bigger injectors from source not vendor
4) either modify the stock W/G or get a Tial
5) get a better clutch

I really wouln't bother messing withthe K26 b/c even though you can make close to 300 it is only at a short area in the power band.


If you are really looking to make power jump right to the turbo.

I just made over 400h/445tq with about $600 myself although it is very unorthodox

[Techno Duck]

You can very well bolt on a new turbo and go..but i would consider bulletproofing the engine a little. Replace the headgasket, redo the vacuum lines..etc.

A new turbo will vary in cost depending what your looking for, but plan on $1000-$1500. A few rough idea of what you need to support a bigger turbo are bigger injectors, a proper way to tune the car (piggyback type setup) and gauges to keep you from blowing the car up (boost, wideband).
