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

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.

[@964Luftballoon]

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?

[@RegalAutosport]

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

[@empeg9000]

[@mikejuzenas93]

Nice work! Did you change out the DMF to something lighter, say an RS one if the engine management system can accommodate?

[@RegalAutosport]

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.

[@mikejuzenas93]

@@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.

[@yjmsrv]

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!

[@RegalAutosport]

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)

[@gavinc74]

The heater system in air-cooled 911s if in good mechanical condition and adjusted correctly is actually quite good.

[@yjmsrv]

@@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.

[@R0yL33]

Impressive gains considering no cam change. No sacrifice of mid-range power. No air filter?

[@RegalAutosport]

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.

[@bernardmclake3898]

Standalone ECU and you/owner decided to keep twin distributor set-up? Interested to hear the reasoning behind that. Love the ITBs.

[@RegalAutosport]

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]

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

@@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.

Of course, if you don't care for any of the above,it's not the upgrade for you.
