I recently purchased my 951 in October of this year after selling my "S" that I had for 4 years. It came with a MAF Autothority setup / Stage 2 chips but I'm looking to do some power mods this spring and wanted to start the planning now in the winter months....looking for the best mods for the buck.
Any suggestions, be specific.

For power mods, I would suggest - in order of best 'bang-for-the-buck-quotient' - cat delete, adjustable boost controller, DP wastgate, then larger exhaust. Do you already have a 3bar FPR? Also, FWIW, I would invest in a WBO2 sensor and a boost gauge before adding any other mods.

first, before you start power modding and stressing the motor and related parts, go through everything and make sure it's all tip-top.

i wouldn't be surprised if this alone costs you $2k.

I would ask WHY do you want to do mods? What are you looking to get OUT of the car? If it's something like track driving, then your money is best spent on seat time to make you a better driver... If it's to impress bench racers, then go for bling. If it's for a dyno shoot-out, dive into the engine mods. If you're looking for handling, start with the best wheels and tires you can afford, then move on to suspension.

Just wait for someone to sell their already hopped up car. You will get the mods for free.

I'm still learning about the turbo and I'm not too familiar with everything yet but the PO already did a MAF setup , chips and installed a custom boost gauge infcorporated on the front pillar. He also installed an adjustable boost controller that he told me was set @ 15. The boost feels great as compared to my "S" and the car is pretty quick as it stands right now.
I'm probably looking to do something with the exhaust...possibly headers and 3" Lindsay exhaust. I also don't want to mess too much with the emissions stuff but I'm willing to swap out the CAT once a year just to pass inspection.
I'm looking to keep the total cost of mods to under 1K...not looking to spend more than that.

Buy a Zeitronix wideband lambda with EGT, boost and o2-sensor and save the rest of the money. Then fine tune and find the next thing to upgrade.

Btw, what kind of chips is in the car? There are a few that are stone age tech.

??? Sweanders...you're talking greek to me...
Stage II Chips

turboted

Looks like you already have a wideband. Does the lower gauge in your A-pillar pod read numbers that vary with engine speed and register 14.7 at idle? Next step is to determine whether or not the PO upgraded your wastgate or not. The LR 3" exhaust is a very nice peice (and affordable) but a PITA to install (be warned). I have no experience with aftermarket headers, but personally feel your money could be better spent elsewhere, as the power gains are not THAT significant. As far as your chips and MAF, the Autothority stuff does not enjoy the best reputation on this forum as the technology behind them is a bit outdated. I have the same MAF and stage 2 set from APE and plan to switch to a different set of chips soon. I expect this alone will make a significant difference. My $.02.

the lower gauge in the a pillar is the autometer run-o-mill narrowband.
Tial 38 + sfr adapter + boost controller + 3 bar + wideband (Innovative, AEM, Zeitronix....)
well...if i had bought a running car that's what I would have done just as a band-aid for boost addiction.

Stage II what? Autothority?

I suggest that you search this forum with a list of words and read every thread containing them. It will take you a weekend or so:

I would second bacon its a great modification. However, I think you just need more octane.

PorscheDude1

I love bacon. Unfortunately, it make my car a little slower.

sweanders

Ok, after doing the bacon mod search for lexan and carbon fibre

Hey Peter, Since I had similar mods to yours I would agree with others get rid of the cat and put my exhaust on. Don't waste your money on headers, yours are not leaking. If I had the money and I wasn't modding my suspension at the moment, I would do a Wide Band O2 and get rid of the narrow band. Then after that I would do the wastegate. I did what you have first and wished I had done the suspension stuff I have now first, realy changes the car. Since you already have the maf (jealous) I would do the 3" exhaust next about the price of just a test pipe. It would get rid of almost all of your lag.
