Are there any owners of Porsche 997's (naturally aspirated) who have installed a bolt-on turbo kit by Prototech (located close to Fort Lauderdale, FL) that can provide any personal opinions based on experience? Please provide any comparisons if possible and opinions on reliability.

Prototech does sell a kit. It is a Twin Turbo bolt-on for the 997S that costs $15,000 for parts plus labor and your cost to ship or drive. It offers more HP than the TPC and can be installed on a manual or tip tranny. I thought about maybe just buying a used 911 Turbo (2007), but these kits seem to provide more HP than the 911 Turbo if fitted on a 997S.

Original Post:
Does anyone know if Prototech have turbo kits for Naturally Aspirated 997's? My local Porsche Mechanic mentioned that these are one of the best. But I believe they only do mods for 997 Turbos.

 

We have a thing called Google. type Prototech and they have a website. and best of all a phone number. 954-771-2654.

Sorry i don"t mean to be such a d*ck. but... some of these questions are answered by a simple online search. Now if you had some technical question as to who has this kit installed and wanted some reviews.... then I totally understand.

Again Pardon my Rudeness....

 

Soo rude lol

 

Good boy y2kgixxer

 

Yes, I'm pretty familiar with the "thing called Google", which is where I found "this website" called Prototech.

· Did it have answers to my questions? No.
· Did I want to call and get a bias opinion? No.
· Was my question too general? Yes. My bad.
· Did I need a rude answer? Not from a group I would have expected a respectful response.
Which is why I turned to Porsche 997 enthusiasts who may have purchased, inquired, and installed these kits; with the idea that someone could offer a few technical reviews, comparisons to other bolt-on Turbo Kits such as TPC, and related opinions or experiences with this kit.

So let me make my question a bit more clear so my thread hopefully receives valuable responses and not primitive IT guidance.

I have not found any comparisons with TPC's 997S or Non-S bolt-on Turbo Kit. I am planning to purchase the TPC, but my local Porsche mechanic mentioned experiencing a rough fit with the TPC, but that was on a Cayman install. He has done upgrades on Porsches, owns a Porsche shop and his family has raced Porsches for years. So he has a pretty good knowledge on the 911. However, he could be partial to the product due to his experience or professional relationship with them.


Any information, guidance or reviews from others would be appreciated in order for me to make a decision on what to purchase.

 

A few things to consider and I'm not debating which kit is better just some advise from someone who has rebuilt over 300 cars in the last 20 year including the one in my in my photo (which including the car now has close to 300K invested in it and it is worthless to mostly anyone) Is your car AWD (mine is not a getting close to 600hp to move in a car that weighs a little more than my Fiat Abarth takes practice and if my car had traction control it would never move at all ) Unless you plan on keeping this thing for a long time I would advise against doing it. There is more going on than just bolting on a kit and the results will NEVER feel the same as factory. My car uses a modified supercharger and luckily I have 3 other cars since almost no one ever gets in it for a second time. I am glad I built this thing but Porsche dealers call it a kit car and for the most part that is what it is. In the end you will be much better of in a turbo (get a tune, plenum, valves, exhaust etc) and you will get yourself another 75hp. When doing stuff this extreme to any car you better know what your doing if something goes wrong (which it does and it has for me in many many cars). Good luck.

 

agreed, you can pretty much google anything these days , so why have a forum? Oh yeah, so we can talk about cars with fellow enthusiasts. The rudeness is why i left 6speed for a few years. Good to see that some things never change. Imo, for the price of adding the turbo, you could get a 997.1 tt and retain some value. We have a 370z here at our shop with an aftermarket supercharger and with the money he spent , he could have gotten a gtr. Its on consignment here and no one has even looked at it, much less test drive it.

 

well after a quick google search (like MENTIONED above) lol there is not any info about there kit for a non turbo car, and to be honest I have never heard of an off the shelf tt kit for a 997 na car. TPC does build a single turbo set up that works great. Now when you said that one kit makes more power than another your obviously moving more air flow and feeding more fuel. You could simply increase the psi however the TPC kit is showing a 100hp increase at a relatively low psi (6lbs) I believe. Plus there are plenty of the TPC kits being used.

 

Agree, plus it's cheaper and it's proven. Mine was installed in Oct 2009 and it's still running great w/o any issues. There are quite a few of us on here, not one complained about it. For all we know, OP's mechanic could be a family member of Protech's. I go with what's proven, TPC could give you as much hp as you want but they will not warranty it, they will only warranty it at minimum boost (< 6psi). They build it to be reliable.

 

Thi is the best and most knowlodge post I ever read here, in few words you said it all. I also have been making many mods ever since 1998 when the Boxster came out. I had a TTP turbo kit installed on the 2.5L engine that blow few years later and then I put a 3.4L 996 engine on this same car apart from many other mods on several cars. You really need to know what you are doing and expect to have some headackes in the process, it´s part of it. These 9x7 engines are not prone to receive force induction, for some reason Portche choose the old engine to put a Turbo on the 997 & 997 series.
