JV911 Report post Posted 2June, 2014 Hi all, You may have read in the intro thread that I recently acquired a 964 C4. I had been looking, unsuccessfully, for a C2 when this one popped up. Having done a lot of reading and talking to some very knowledgeable people I’m confident that the 2 main gripes people have with the C4, i.e. understeer and extra weight, can be ironed out fairly easily with nice suspension and a diet respectively. Given it will be a street car, the extra grip the C4 offers will be welcome. The skunk works at Autohaus Hamilton have been entrusted to tackle the majority of the work. We have taken some ideas from their Group 4 car, as well as the C2 RS and C4 Lightweight, tweaked them and added plenty of our own. Here is a summary:Mechanical Engine blueprinted and balanced Custom grind Elgin cams Titanium valve springs and retainers Ported headsECU retune, MAF,Motec M84 ECU ARP rod bolts 993 head studsHeavy duty clutchRS flywheel Semi-solid engine and trans mounts Fabspeed RSR headers and muffler Billet rocker covers GT3 oil pump Carbon RS heater pipe Fuel pump993 RS valvesMahle high compression, moly-coated pistons Rothsport (Jenvey) ITBs and plenumSuspension & Brakes Bilstein PSS10 coil overs and rear strut tops Wheel alignment, corner balance and set ride heights993 Turbo “Big red” brakes, braided lines Brembo 355mm & 328mm brakes with 2 piece rotorsBraided lines 993 steering rack brace 18” Victor equipment - Zehn 18x8 ET45 and 18x9.5 ET49 Pirelli P-Zero tyres 225/40/18 and 265/35/18Panel Work/Exterior 993 Cup mirrors Rolled guards Respray (997 GT3 RS grey-black) Ducktail Ducktail grille 3.6 grille badge Engine lid hinge adaptors Replace all rubbers and seals Clear indicator lenses (front bar) Brake ducts (front bar) Side indicator delete New tail lights Rear reflector delete Headlight washers deleted New headlight lenses and HID upgrade New rear bumper for dual exhaust New windscreenInterior ½ cageRecaro pole position Sparco Evo seatsMomo Prototipo Sparco R-345 steering wheel Rennline quick release Wevo shift coupler RS door trims RS carpet Dash, knee pads, door tops and centre console retrimmed in alcantara Rennline billet gear knob & door locks Leather gearshift boot Carbon fibre console inserts New sun visors New headlining Rennline pedal pads Rennline floor boards Schroth 6 point harnesses New seat belts Extinguisher Remove soundproofing VDO headunit (CD9303UB)Miscellaneous Oil hoses Diff seals Steering rack boots Drive shafts Drive shaft boots Engine soundproofing Overhaul air-con New alternator Alarm and 3 point immobiliser And a few (i.e. many!) other bits and pieces My impression of how it will look, minus the ducky and a few other 918 inspired touches.

T-Man Report post Posted 2June, 2014 Wow!!! Pretty impressive build sheet. Copious amounts of progress shots are mandatory. Quote Share this post Link to post Share on other sites
Tit Report post Posted 2June, 2014 Yeah! That's almost the value of the car again in mods! Make sure you post lots of photos!! Looking forward to your updates! Quote Share this post Link to post Share on other sites
Pauly Report post Posted 2June, 2014 nice list. I'm not sure what "sport camshaft" means or "sport valve springs" but i do suggest getting your head worked to accommodate the camshafts with at least port work. or better, larger valves. Went through the same deal with my head. Make sure you have an idea where you want your power band too. with a camshaft expect it to move right a bit so you'll loose some bottom end torque.

"almost"? ummmm, something like that loads of progress shots to follow nice list. I'm not sure what "sport camshaft" means or "sport valve springs" but i do suggest getting your head worked to accommodate the camshafts with at least port work. or better, larger valves. Went through the same deal with my head. Make sure you have an idea where you want your power band too. with a camshaft expect it to move right a bit so you'll loose some bottom end torque. Yes head work has been taken into consideration, as has the power band. It will be a nice "streetable" engine with broard torque curve. Not chasing absolute power.

Pauly Report post Posted 2June, 2014 unfortunate you're not in Melbourne. would have love to see this when it's finished. Quote Share this post Link to post Share on other sites
FlatSix Report post Posted 2June, 2014 Wow that is one hell of a list! It looks similar to my list, although I've given myself 5 years to get it done! Looking forward to see some photos. Quote Share this post Link to post Share on other sites

clutch-monkey Report post Posted 2June, 2014 that engine rebuild should net you ~300hp at the engine with a nice fat mid range, will be very nice.. Quote Share this post Link to post Share on other sites

Guest 550spyder Report post Posted 2June, 2014 Ducktail. Are we talking RS seventies ducktail? Liking it already. Autohaus will do a good job. Re your 'almost' comment, I think we can safely say this project is 'almost an investment' (in the soul). Sounds like a modern day RS 'interpretation'. Lots of tasty things on that spec list I love. I can only assume that your reference to engine soundproofing is 'removal' ! The only option now is to amend your log in name to skunkworks964. I am salivating at the prospect of this build. Bring it on. Quote Share this post Link to post Share on other sites

I can only assume that your reference to engine soundproofing is 'removal' ! The only option now is to amend your log in name to skunkworks964. I am salivating at the prospect of this build. Bring it on. Yep the seventies ducktail. Inspiration is taken from the 73 RS, 964 RS & C4 LWT, even the 918 Spyder, while keeping the clean lines of the 964. Lines that I consider the last of the classic 911s. Engine soundproofing is being replaced rather than removed. The engine mounts will amplify the noise a bit so I didn't want it to be too over the top. And "almost"...yea well you onliy live once. that engine rebuild should net you ~300hp at the engine with a nice fat mid range, will be very nice.. That's what we're thinking. Should be fun given we'll be able to pull a few kg out of the car. Quote Share this post Link to post Share on other sites

JV911 Report post Posted 4June, 2014 As promised, some pics of the donor car which is, as you can see, a rather clean and very straight example. One could be happy cruising around in as is, albeit with the various leaks etc fixed. However we have other plans It should be stripped within a couple of weeks. Excess parts (seats, wheels etc) will be sold off so let me know if you want to dibs anything. Quote Share this post Link to post Share on other sites
JV911 Report post Posted 4June, 2014 And here is the first draft artist's impression. There are a few tweaks ie clear indicators but it is pretty close to how we envisage the end result. We're looking at a couple of changes to the abovementioned build sheet including Brembo brakes with 2 piece rotors and a Motec computer for more precise tuning and allow us to de-clutter the engine bay even more. 1 Black Pearl reacted to this Quote Share this post Link to post Share on other sites

SteveT Report post Posted 4June, 2014 So is the car with the reddish interior the one that you will end up driving or is that the one you are using to strip the mechanicals out of to install into the other chassis? Quote Share this post Link to post Share on other sites
JV911 Report post Posted 4June, 2014 So is the car with the reddish interior the one that you will end up driving or is that the one you are using to strip the mechanicals out of to install into the other chassis? I only have the one car. It's the one with the burgundy interior. By other chassis I assume you mean the shell in the background which is another customers car. From memory it's a 930 being backdated to 73 RSR look. 1 SteveT reacted to this Quote Share this post Link to post Share on other sites

JV911 Report post Posted 5June, 2014 Getting close to finalising the colour scheme Oh and the Recaro seats have been ditched in favour of Sparco Evos, as has the Prototipo steering wheel. Miura Green for the highlights (cage, calipers, interior stitching). Grigio Telesto (aka Battleship grey) for the body, albeit a shade darker. And these are the brakes I mentioned yesterday. Still to be confirmed. Quote Share this post Link to post Share on other sites
Tit Report post Posted 5June, 2014 I'm sitting in a sparco evo right now (home-made office-chair). Don't know what the recaros are like, but when this evo2 was in my car it was the most comfortable car seat I've ever used... Quote Share this post Link to post Share on other sites
JV911 Report post Posted 5June, 2014 Much of a muchness in terms of look and quality but the Sparco fits me better. It's wider in the shoulders and narrower in the hips than the Recaro. Quote Share this post Link to post Share on other sites
