Title says it all: need to make my Z compete with my dads 2009 (997) Porsche 911s. Compete meaning that it can keep up, isn’t a convertible (ouch) and has a similar/better power to weight ratio. This all happened because me and my dad got into an argument about whether it’s better to build up a cheap car or drop a ton of money on a newer performance car. Doesn’t make sense to spend double the money when you can get a similar and more unique result by building a car yourself. So now I have to show him why he’s wrong (hopefully).
So I don’t really want to blow him away, as I do daily drive the car and don’t want to break it trying to make 500hp, but I do want to make around 425 whp. Now I have posted about building up my Z to around 400 for a while and now I’m actually going to do it (I have money). What I need to know is if the list of performance upgrades below is sufficiently accurate in creating a Porsche “beating” Z:
What I got (not much lol):
- Megan High flow Cat-back exhaust (only 2.5inch)
- 17inch wheels in front and back with some pretty decent rubber (inch wider than stock)
- s*** cold air intake
- 2.5inch downpipes
- New stock sized CHRAs
- Stock everything else (timing and intake butterflies have been messed with for better throttle response)
What I need (I think):
- JWT Dual intake/Dual MAF setup
- Electronic Boost Controller (Greddy)
- Bigger injectors 615cc or 740cc with adapter kit (Would be nice if you guys could give me some reference on what size injector I should go with)
- ECU Chip (Also wondering on which one to go with, was thinking Z1 or JWT)
- Push the stock (but new) turbos to about 15psi
- Do some deletes such as: Carbon Canister, AIV’s, Spare Tire
- Maybe a lightweight driveshaft and lightweight pullys too
ALSO:IMPORTANT QUESTION
If I was to do a build like this, what other auxiliary gauges should I install other than a boost gauge. Thanks
This sound right to you guys? Let me know, I really want to start throwing this thing together soon.

Re: Need my Z32TT to beat 997 CARRERA S to prove Porsches are OVERRATED
*whoooo boy*
I'll post more detailed response later, but you're not outperforming a Carrera with ebay parts on an antique Z32. Period.
You also didn't mention what "winning" would mean. Road course lap times? Quarter-mile? Top speed? Autocross? Skidpad? Does Pops have any track time under his belt? If so, the better driver is a bigger factor than the car.
"Pretty decent rubber" - What does that mean?
"Megan exhaust" - No improvement over stock (and 2.5" is plenty, btw).
"Timing/intake butterflies have been messed with" - What does that mean?
You're absolutely right, that it's more rewarding to build something unique and cool - but it's a 30 year old car.
Restore it to as-new condition first instead of worrying about keeping up with a completely unrelated car. If you've never driven a brand new Z32TT, it's a formidable car in its own right. Compression test, new bushings, replace all wear items, and enjoy the car for what it is. All those cheap mods are doing is destroying the value of a classic car.
Welcome aboard!

Re: Need my Z32TT to beat 997 CARRERA S to prove Porsches are OVERRATED
p.s. Just saying "Porsches are overrated" kills any credibility you may have had. It's an overly broad, nonsensical, unsupported statement.
Re: Need my Z32TT to beat 997 CARRERA S to prove Porsches are OVERRATED
A couple things to clarify:
One, I am a huge fan of Porsche in both racing and their domestic vehicles, I'm literally planning on getting a 917k tattoo in the future. When I say overrated, I'm referring to all the a** kissing that surrounds these vehicles. They are fantastic, don't get me wrong, but they aren't perfect either. Two, I should have been more clear with the point of this build. It's never going to be a 997 killer with bolt-on parts, but the point of the build is to make something with a similar power to weight ratio that's a bit more fun to drive. I'll never beat a PDK 911 with a 20 year old 5 speed and VG under the hood on the track, and I'm not trying to. I want to show my dad that having all the new tech and go fast engineering is cool, but something a bit older with some tuning can be a lot more fun if you don't care about track times or 0-60s. The car as is is a ton of fun, but getting to those higher speeds a bit quicker wouldn't hurt the fun factor.
To address your questions AZhitman, "pretty decent rubber" refers to the fact that the tires are literally brand new and are Michelin Pilot Sports (not amazing but decent considering I'm 18, in school, and don't have a career yet). When referring to the timing and butterflies on the intake being messed with I am talking about the throttle body. If you don't know what I'm talking about here is an article where a guy did it to his 92: http://s95014253.onlinehome.us/63104/182732.html . As for your idea of restoring it, I've done it already. In the "What I got" list I didn't mention the fact that I have been replacing everything on this car slowly over the past year or two. You're a 1,000% right btw, the car in stock form is a hoot. That's not what I'm going for though. And as for beating the Porsche, I don't mean doing a full tear down Rob Dahmn style build like his RX7, lol. I just meant that I wanted to show how these cars can be a lot more enjoyable than some new preformance cars that focus too much on numbers and not feel (especially because the man never drives the god dam thing anyway!). I've driven the 911 countless times at speed and can say that I love the car (with the exception of the convertible top) and would consider buying one if they didn't cost so much damn money. Hope that clarifies everything, I don't mean to sound condescending in any way to you guys here or the Porsche guys, just wanted to make sure that someone would actually read this thread unlike the three billion other "How do I get my Z to 500hp" threads that you always see (that why I dropped the "Porsches are OVERRATED" line in there).
Thanks for responding though. I'm excited to see your full response later, and I really cant wait to work on this car more, I love it!

Re: Need my Z32TT to beat 997 CARRERA S to prove Porsches are OVERRATED
Also I could care less about the value of this car, it's gonna be mine as long as I can keep it around. I'd rather have more fun driving it with tasteful mods than worrying about keeping it brand new.
