After installing a CAE Racing Ultra-Shifter earlier in the year, this customer wanted more from his 964 C2. The best way to improve the driving experience in many aspects is by installing an Individual Throttle Body Kit or ITB Kit. There are many kits on the market and after seeing some of the other kits on the market went for the UK designed and manufactured AT Power Throttle Body Conversion Kit.
OEM intake systems are generally designed to keep intake sounds to a minimum, meet emission requirements and hit 'a' performance requirement and not much more. ITBs improve performance by placing the atmospheric pressure closer to the cylinders which improves the throttle response as well as power and torque potential. The AT Power ITBs take this one step further with their 'shaftless' design which eliminates the conventional restriction inside the ITB intake path which is the throttle shaft, this results in even higher potential output.
At the same time as having the AT Power ITBs installed the Longman Racing ECU is installed and plugged into the original harness for the OEM features to still work but with more up-to-date control for the fuelling, ignition and many other maps inside the ECU for optimised horsepower, torque, driveability and safety.
Whilst AT Power take care of the top of the engine, at the bottom, Fabspeed Motorsport Headers are installed and complimented by a custom Alunox Inconel exhaust with centre-exit tips.
To put more of the power down to the ground, the Wavetrac LSD is installed which replaces the factory open differential. When one wheel slips, the factory differential sends all the power to this wheel, until traction is regained, frustratingly halting momentum. Whereas with the Wavetrac LSD power is sent to the wheel with the most grip and evenly across the axle, ensuring you are making the most out of the grip available for faster acceleration and cornering speeds.
Other upgrades installed include: Rennline billet top and bottom rocker covers, RSS engine mounts.
🔴 Baseline Output = 264HP & 251lbfts
🟢 Max Gains = +40HP & +33lbfts
🟢 Peak Gains = +37HP & 10lbfts
🟢 Max Output = 301HP & 261lbfts

The 964 C2 is my absolute dream car! The owner must me so excited with these massive improvements. Enjoy and drive safe!
It’s now ours too! It’s such a joy to drive, look at and ride shotgun with these upgrades ❤️
this thing is perfectly sorted - good to see the owner caring for this car this way
Thanks for the comment! He properly drive it too 🔥🔥🔥
What an utterly stunning motor - the owner has great taste, good to see it actually being driven like it should!
Thanks for watching!! He certainly does drive it HARD, perfect!
ITB's or carbs, you can't beat that old school sound & drive!
Enjoyed watching this video. I like the tutorials, sound check, and finally a test drive to showcase everything 👏
Absolutely! The sound is incredible! Glad you enjoyed the video!!
Thank you for showing us someone hooning that thing down the road. I was waiting for a few nice rips....cheers!!
Thanks for the feedback! Glad you enjoyed it! This was the owner driving the car :)
Incredibly informative video with the right balance of technical info mixed with artistic cinematography
Do it again
Thank you very much, happy to hear you enjoyed it :D
Please more of these longer videos‼️Awesome stuff as always guys
Thank you! We are working on making longer videos for our subscribers for sure!
I spend 2h per day on youtube and this was my favorite content of the week ! Super good works guys !
Thank you so much! We are happy to hear you enjoyed it and it was your favourite piece of the week :D
Lifetime transferable warranty is absolute madness. 🙌🏼. That black piggy absolutely screams now and Seth’s face says it all when driving it. Top work. 💯
hahah yes Mex, wait until you hear it at Players!
@@RegalAutosport Cannot wait.
What a tastefully modified 964 and you did a great job! At least, you preserve the original spirit of the 964 and doesn't ruin it like Singer and some other companies do. It is a fantastic 911 generation, it doesn't need to be backdated to obtain a false 60's 911.
Thanks for your kind words!!
legit work by the way
Thank you Sir
top work as always!
Thank you ❤️
Great work! My dream, A 964 of my year birth! (with same preparation😍)
Thanks for your kind words!
So nice 👌 Want a 964 bad 😬
Make it happen!
Lovely, that’s some serious ££££££’s commitment by the owner right there💪🏿, would love similar in future. Lovely setup though sounds slightly different probably to do with the GT3 exhaust system.
Thanks for watching! Certainly a bit different with the centre exit 🔥🔥🔥
That came out sweet! Needs to pic a nice color for the cage & air cool fan....👍🔥🏁
Thanks for watching and thanks for your comment!
absolutamente espectacular.
Thanks!!
Burako Bardo!
That is how a 964 should sound and drive....
Why thank you!
Sic badass
Thank you!
Great work guys. Regal Motorsport at their best. I am hoping to get a Wavetrac diff for my M240i.
Thank you! Hope to see you soon, we've got plenty in-stock!
@@RegalAutosport I live up north but was considering a trip down (when I a can) to Evolve to get it done.
Nice! Evolve are good bunch ✌️
Thank you for a great Video, this seems a really well rounded upgrade package for a C2, what changes would you make to the package if you were doing a C4 ?
Thank you for the comment and kind words! The package is similar for the C4, you can even do the Wavetrac upgrade too to improve the rear-end traction and grip.
Just like “Black Bird” in the movie “Devil Z”
Damn right.
Beautiful work! Okay all in what was the gents tab?

I'm really into classic 911s, I wish you give an approximate cost of the upgrade bundle, that would be really helpful for followers
Awesome to hear and thanks for watching! Pricing is infinitely variable depending on so many factors which is why we don't list it, if you're interested in obtaining pricing please contact us using one of the methods in the description
I love this setup. Is it necessary to drop the engine to install just the ITB’s? Also, would the tuning differ on a c4 that has a lightweight flywheel?
Thanks for the comment! As we were installing the diff too and some other work, it was a better process.
Lightweight flywheel will allow the revs to increase and decrease faster when the clutch is disengaged
Great work. Do distributor-less ignition retrofit exist for this motor?
We can install distributor less if the customer build required it, but this one didn't
Hello Regal can the Wavetrack Diff, TB Kit and Management be fitted to my 964 Tiptronic please ? Don't laugh folk's, I'm disabled so can't drive a manual anymore 🙃 Awesome video guy's I'm well impressed 👌

I want to know more about that induction heating tool on the studs
It's an induction heater, very helpful when working with seized parts
Nice work! Did you change out the DMF to something lighter, say an RS one if the engine management system can accommodate?
Thanks for the comment and kind words! We certainly could install an RS flywheel or a billet single piece flywheel for the best engine response and rev drop/increase without clutch engagement.
Only changes for the engine management would possibly be the idle pull-away which with a flywheel with less mass would require finer tuning.
@@RegalAutosport Thanks! I found the 964 in stock form struggles with a RS flywheel, but its when the throttle drop is sudden, say you are motoring along at 3500rpm and then push in the clutch and do not touch the gas - the DME at times will not do enough to establish idle as the engine is dropping down, and so the rpm dips below where the engine can sustain an idle and it dies. A medium weight flywheel solves the problem. I recently built a 964 engine with 993 SS cams and slightly larger intake valves, and it was even more of a struggle to get the DME to "catch" the idle with a RS flywheel, so we swapped out to a MWF and it's much better.
Impressive gains considering no cam change. No sacrifice of mid-range power. No air filter?
Thank you! When the customer took it out for a drive he was particularly impressed by the low-mid end response/power, which is illustrated in the graph with the big torque gain in that range.
The air filters were also supplied with the vehicle, they are easy to fit should the customer wish to use them.
that sounds like porsche racer!!!
PURE cup car sounds!!
Fabspeed with heat exchangers in England- good luck with that- I have that same setup- the heat is dismal- doesn't really warm up even the windshiled in rain- very- very poor design. I'm about to pull the entire (expensive) system and replace it with Instant-G' s reworked 993 system with all new pipes so I can finally have heat in my car in the winter again. Trust me- those heat exchangers on the Fabspeed are far too small to produce any reasonable heat to the cabin. The ATP ITB's are bad ass though- and wow- you all much have had that car for a spell- Ash's hair went from trimmed and tight to curls galore from 8:05- 15:55- looked like we time jumped several months!
Thank for watching and the feedback! Ash did go from fresh trim to perm in a matter of minutes, quite impressive! This project was over a few months :)
With regards to the heaters, thanks for sharing your experience but we haven't experienced any issues with the heater when they were fitted through the winter (this project was from December - March)
The heater system in air-cooled 911s if in good mechanical condition and adjusted correctly is actually quite good.
@@gavinc74 Stock Porsche heaters are fantastic... no argument there- I want mine back! The FabSpeed design is what I'm talking about- for me- they don't even defrost the window on a rainy day. I live in Colorado- so I need heat- and the original air-cooled system would start getting noticeably warm in just two blocks of driving- but I "upgraded" for better performance- and now I'm taking them off (and selling them) and replacing them with modified 993 exchangers into a new better flowing header system by Instant-G- the guy that build Jack Olsen's Black Beauty motor. I have just had a terrible experience with the FabSpeed heater setup.
What front lip is that? Where can I source that?
Not sure, we did not source it for the customer. You can find the customer on IG @players_jay
What's up with the roof liner, Is he putting a sunroof in?
The interior of the car was delivered part finished and is being delivered to another company to finish
So its running without an airbox/filter?
Sure is! We did provide this customer with the air filters
Standalone ECU and you/owner decided to keep twin distributor set-up?
Interested to hear the reasoning behind that.
Love the ITBs.
Great question! There are many reasons to retain the existing twin distributor setup, the main ones being authenticity, arguably adding more points of failure (more parts) and additional cost that comes with completely changing the ignition system.
The standard distributor also has a built-in hall sensor which is effectively the cam sync, so removing it would mean re-producing a sync sensor.
Completely changing the ignition system is a lot of time and cost for marginal gains, decisions like these are made with the customer according to his goals/requirements of the build and on this occasion, an ignition system change wasn't required.
@@RegalAutosport appreciate your reply. Cheers
@@bernardmclake3898 No problem!
I got the impression from the video it works as a piggy back ecu only changing fueling, timing etc as required and the factory ecu does all its usual things.
@@gavinc74 The factory ECU is completely disconnected, in its place is the Longman Racing Euro4 ECU with adaptor loom to the factory harness
About whats the cost for that up grade

So there are no air filters on the car now? Is this a road car?
We supplied the customer with the option of some air filters should he with so install them.
Can it be modified to be distributorless?
Yes of course
where did you source the exhaust system
Part custom and part Fabspeed
Who did custom work?
Wow incredible. What was the cost of the total package ?

Nice work but why not clean the engine when is out the car?
Thanks for the comment, this was not on the schedule of work
Blackbird?
.
I see you are a man of culture
Why remove ac
Because the customer requested it
Yo is that Seth Rogan
ahahaha!
Holy shit the hair change throughout the video lmfao. How many weeks did this overhaul take?
ahaha! Lockdown hit some people harder than others.
This upgrade took a couple of months to complete from start to finish.
You brits must be quite reckless, I've never seen so many safety warning decals on a 2 post hoist.
hahahaha
More work less talk.
Thanks for the feedback!
I don't know. Plowing money into old platform sounds uneconomical. Wouldn't it be better to buy a new model Porsche and get a lot of the benefits immediately?
Hop in a 964 and then hop into a 992, or even a 993. They are all very different experiences. If speed is your only goal, then for sure just jump into whatever 911 turbo you can afford, but it won't give you the experience as a 964 on throttle bodies
Lol Billy boy I bloody hope that's sarcasm.
He just needs to tidy up that rear bumper. That’s really annoying me !
thanks
$15-20K for 40HP. LOL!!!
Gotta pay to play
It isn’t always the hp that matters the most, it’s the feeling that you get using that hp. The sound and improved engine response is amazing
@@hardforeveryone118 exactly this, the driving experience is improved ten fold which can only be appreciated really after living with a stock car like this and then wanting to improve certain areas.
We've improved the throttle response at all loads/engine RPMs and improving low-end torque WITH top-end power.
and then you get the intoxicating intake sound.
Of course, if you don't care for any of the above,it's not the upgrade for you.
So you buy this super overpriced sports car, with rust, torn interior... Pay just as much to get it presentable. And then you have to re-engineer the diff, intake and exhaust for another 20 grand to make it a sports car. Porsche people. Gotta love how detached from reality they are.
Is everything okay at home?
@@RegalAutosport You know it's true, the rich have inflated 964 bubble beyond all reason.
