997 Build - Page 3 - 911/Carrera GT - PistonHeads UK

Building a 997 and had some feedback to start a Thread. So here you are Found a decent C2S manual in Black and stripped it back. Will update bits as they get done. My brief is a nice road car, not after power or super lightweight, I have a 991.2 GT3 and 996 Racecar, so not trying to make a fake. I want a clean look so no wings or duck tails. Working with my race team and using only proven products. You wont see centre exhausts and cold air intakes that rob power. Taking the engine to 3.9 with new pistons and liners, work on the throttlebody, plenum and some ECU work to bump up mid range torque. We are confident on what will make and have an engine Dyno so will post REAL FIGURES when done. Not going to 4L as discussed with Porsche Motorsport and it takes too much material away. 3.9 has been done a lot in US and cars have well over 100k miles trouble free. Head will be stripped cleaned and better valve springs put in with valves reseated and replaced as required. Will gas flow but just a clean up not other head work RSS suspension components as they are amazing and dampers built to our spec. Gearbox will be inspected, LSD, cup cables and short shift put in. LWFW. New interior (going Pepita with dark grey) Colour will be revealed but will be Bentley paint (best quality) and flatted with 2 x clear coat. Wheels are Tech Art Fomula 2 (I love a deep dish!) Brakes rebuild calipers, Giro Discs, PF pads, new Master cylinder. we have the ability to change the ABS programming so will see. Lowered a bit but not too much as the rear roll center on 997 is 3:1 so every 1mm you lower the car you lower the CoG by 3mm. They are better with some rake. The look good slammed but dont drive well Front end will have new Cup car PU, rear will be standard (Follow a 997 they look great as standard) New ICE with apple car play, some carbon bits but not too many. Seats will be Corbeau, LWB, in cloth, keeping rears and re-trimming Price to all this including car 60k MAX maybe 55 if I am lucky So far car is great very clean. We need to do a small repair on front subframe or replace thats the only problem. Engine is filthy, oil pump was leaking.

ouf ! good luck with that .. looks like an interesting project.. 997 definitely finding their fan base it looks like

Its only oil, will look like my RSR bits when cleaned

So what colour Bahama Yellow Forest Green Metallic Etna Blue

Bahama Yellow- very nice. Have you seen this site? You could easily lose an evening browsing through... https://www.colors.rs/colors

Damm, I will spend more on samples now than the paint job! Thanks Chris e

Gen 1 Or 2?

Looks a fantastic project. Will enjoy following this.

Billy_Whizzzz said: Gen 1 Or 2? Confirmed on another thread as 07 so .1

Yep Gen 1, Replacing so many parts Gen 2 was a waste. They are cracking on, engine is stripped and cleaned. Front subframe strengthened.

Basic Clean up of one side of Rear Suspenion. Subframe to be cleaned and all new bushes and RSS bits to go on.

Before cleaning and inspection

Exhaust partial clean up, one side done

Jeweller70 said: we have the ability to change the ABS programming so will see. Can you re-calibrate the factory ABS?

Not an expert will find out how its done

I would think about crack testing the sub frame and links etc,its not expensive at £10 per component,great project.

Lovely! With a pepita interior personally I think Bahama Yellow. Forest Green also nice but a darker green would be better (whats like Irish but darker?). Currently run a 997.1 and am looking at the suspension. Bit of a newb... Did 4x shocks last year & top mounts, etc. Looking at doing the arms this year. From the pic posted, which ones are you replacing? I imagine "coffin" and longitudinal, what else? Edit: Actually Forest quite perfect!

Fjord Green for me, and I usually pick a metallic colour, but I cannot see past it now I have seen it, has a touch of class about it! Edited by Yidwann on Wednesday 10th February 11:03

Thanks for the suggestions Yes I run Magnesium wheels on my race cars and we get everything crack tested. The front sub-frames have a problem at the suspension mounting points they need strengthening, its an easy fix On the suspension, most of the multi link parts will be replaced. On the coffin arms we may, but its not really necessary. All new bushes and ball joints. I am worried Bahama looks good on a period car in California, may look bad on a modern car in the UK in Feb! Forest Green looks good, there have been a few 991 RS in this colour and they pop. There is also Lago and Jet. Getting a Gripper Diff made, so working out pre loads. Engine bits are here so machining and fitting liners this week, start rebuild next week. Crank is in great shape and still perfectly balanced. Head is 100% as well, will gas flow and replace seats and springs. Will be bumping redline up a touch to 7400

Jeweller70 said: On the suspension, most of the multi link parts will be replaced. On the coffin arms we may, but its not really necessary. All new bushes and ball joints. If you get a minute I'd be interested to know why yes to the links but not the coffin arms. Also what you're replacing with. I'd struggle with choosing a new colour!

Cool project! I would be very tempted to get rid of the PSE though, it's super heavy and easy to lose some weight going with decent aftermarket boxes. Switchable systems available too.

Corners back on with the original mutlilinks but new Dampers and Top Mounts. RSS bits delayed, will change next week. All components lose re bushing has been easy. Re bushing with Powerflex as we go Have a problem with the front Bumper as wanted to use a Cup Car Front. These need the hockey stick and wider fender and we cant make it look good easily so will chose a different front end now, anybody who knows where I can get a 997.1 GT3 style?

Doh, I meant to say REAR!

On the PSE, I may change but nothing sounds very good, I might get one made

Sounds brilliant, thanks for sharing

Some Exhaust porn, this is still 100 DB with all this, in Europe we run it straight piped and its loud............. Simpson exhausts are amazing, may get one for the 997 build.

With Pic

Jeweller70 said: Its only oil, will look like my RSR bits when cleaned Yes. Isn't vapour blasting wonderful!

Wheel Advice Got these that I like a lot, question on colour, tempted to change the centre to Aurum Gold? Wanted a dished wheel

Refurbed Caliper

Giro Discs Making a lot of progress, looking at paint spray outs next week. Engine pics next week

Colour chosen. Engine delayed a week as fitting liners needs some more complex maching. Wheels going Aurum to match my GT3.

Should look great! Green and gold - similar combo to the Snakebite car from RPM Technik

Wish I could make this sort of fast progress on my projects.

I know its similar to the RPM car colour, was not my intent. Going to some testing on set up at Bicester Heritage. We should be done in 5 weeks. We are hoping to get the sound right, larger TB and Plenum, will do the Helmholtz hack on standard air box and welded valves open on exhaust. We have some options to tune the induction noise. We want engine noise not exhaust noise. Left the sound insulation in as without you get lots of tyre noise. Doing some clever hacks to the front bumper and we have had a splitter made so front will a one off. We got lucky on the base car, the rads, condenser, water unions were all spot on and cleaned up like new. The car came apart like a dream and a lot of the bushings were still perfectly ok, but I have changed them all anyway.

Who's doing the colour change and is it very costly? Been wanting to change mine too. Getting bored....

Its someone who did a bumper paint for me before. One man band, but I like his work. Based in Bucks Happy to share when done!

Please do I'm thinking of putting a new suit on mine like this in signal or mint.

Jeweller70 said: Refurbed Caliper This is great Jeweller, really inspiring me to decide this is the way I want to go. I am probably a little way off starting! But its ideas heaven!

Nice work so far! Thanks for taking the time to write up. Watching with interest.

TB and new APR Head bolts

Heads, cleaned and ready to inpsect with new stem seals as a mimimum

Off to paint

Jeweller70 said: I know its similar to the RPM car colour, was not my intent. Yes I was just meaning it as a coincidence (of good taste ) rather than implying any copying etc. Is the speed of the project benefiting from there being no racing going on? The project is certainly moving along at racing speed.

Loving the relentless pace of this! Like the sound of how it'll end up.

Race Team found time in between jobs. They got another build now so thinking of charging them comisson. They reshelled my 991 cup car in 8 days. The little details will take time like final trimming and set up. Will be done in 4 to 6 weeks They have the set up now to run the engines on the in house engine dyno. There is talk of a boxster next, that could be fun.

Will be a bit quiet for next 2 weeks as car is painted We have figured the best engine breathing combination and will be interesting to see HP and Torque figures Torque is what we are after and hope for a good increase and flatter curve. Using 200 Cell Cats with X pipe and standard manifolds and PSE. Will map on our Frau Engine Dyno and then check on rolling road to see losses and load impact. Larger TB and Plenum as said will be the intake work Trimming is progressing with lower dash, glove box, hand brake, gear gator and centre cubby in Charcol Alcantara.

Nice, really looking forward to next installments, particularly that interior.

Material arrived, I thought about Pasha, but went with the classic

Will be going back to bare metal on a lot of the car

Enjoying following your build - impressive momentum!!

Paint is cracking on, car is primed. Body was good except bonnet Hint on the interior with the seat, wanted lightest possible.

May I ask : what is the specific seat model? it looks great / as does the whole project.

It’s the EVO RB, custom made with Pepita.

Jeweller70 said: Paint is cracking on, car is primed. Body was good except bonnet Amazing progress.. Very interesting Project What was wrong with the Bonnet..? Dent repaired & filled etc.?

Like the way this is heading, no one seems to take these engines apart much unless for repair. Are there no upgraded camshafts to fit 'whilst you're in there' are you upping compression with pistons or anything or pretty much a standard rebuild in the end? It'll be interesting to see the results on the plenum/ larger TB too, the fella that mapped my old bmw specialises in Porsches too and categorically says they dont work as marketed and he can do better with the original. He did a big post on his Facebook page a couple of years back with a lot of backlash from people that had bought them. Love the colour combo and those seats, it'll look cracking.

Don’t want to change the drive ability so leaving Cams. Key with any breathing is to do intake and exhaust. TB and Plenum paired with 200 Cell Cats will improve breathing. Will soon see by how much.

Have you seen the x51 carbon airbox. You'll need some tissues handy before you do.

My opinion is wrong ? What ???? Because I don’t sing to your tune I’m wrong and you’re right ! 😂 You sound like one of the 996 experts off the 911 U.K. forum 😂😳 You’re obviously quite well respected by some posters on here, no doubt giving Kudos to “Slippy” gives your loyal band of minions some presence !

I really like what the OP has done with this. I've found it quite inspiring. I'd love to have a go at something similar but would have to start with a more modest base car. 996 or 987 could be a great starting point for developing something personal. Ducktail and Fuchs falls into 'should be wrong but it's right' territory for me

Ducktail and Fuchs falls into 'should be wrong but it's right' territory for me I don't think the mid engine cars work well with these larger capacity engines as they seem to struggle to get rid of the heat as well as the rear engine layout.

Got the lighting correct

Jeweller70 said: Got the lighting correct I'll be honest and say that I wasn't totally convinced by the earlier photos but in the above shot the car looks absolutely fantastic. The colour scheme works really well and it looks very retro in an unfussy modern way.

Echo the above, that looks bloody fab

Jeweller70 said: Looks brilliant

Agreed, that looks lovely! Very nice, look at that brake diameter!

Looks fantastic!

PGNSagaris said: You’re wrong. Ducktails are cool Evening Fantastic tread each to their own but....... Ducktail Love it

Done about 600 miles now. Gearbox is now great and brake feel spot on. Handling is as I want it but ride is too firm we are going to drop the spring rate about 10 to 20%. Car has settled a bit so will raise 5mm or so as well. Clutch is too aggressive so we will replace paddle clutch. Still not mapped but so much more mid range than standard. We backed to backed with a standard C2S and in gear the car is much stronger. The more I see it the happier I am. It’s the right amount of HP and involvement for the road. I enjoyed doing it and the feedback has been very positive. Signing off for now unless I build another one😀

Try switching to decaf perhaps? And using fewer exclamation marks

Really enjoyed this thread (well most of it!). Really impressed at the pace you have made it all happen. Enjoy it!

Great thread. Thanks for sharing.

Jeweller70 said: Looks fantastic a really nice custom build. My only dislike is that rear badge which looks cluttered like the newer 911s. Personally I'd declutter with a 911 badge. Perhaps in the same gold colour would finish it off well? Looks retro a little like this. Anyway still stunning in it's own right!

Jeweller70 said: Congratulations to your new toy! This was a speedy process The dark green with gold looks the dogs! Whilst I am a sucker for R stripes on 991s (I mean, just look at Cheib's Lava GT3 with them and don't be blown away), I'd have your car without them. I may have missed it: Which suspension did you go with?

Bilstein PSS9

Maybe worth having a look at Tractive in Kings Langley

My team have been offered a tractive set to test I may put that on

Jeweller70 said: My team have been offered a tractive set to test I may put that on "To test" ? Your team needs geeing up, they are about 5 years behind the curve Edited by TB993tt on Tuesday 8th June 09:33

Ahh the joys of Pistonheads I didnt want active suspension. Having raced many cars for many years and tries every kind of suspenion I do have a understanding of what works. Most of applications dont need active and as we can get bespoke builds from Moton and Ohlins to our damper curves there is no need. I am sure tractive are good but on a road car in the UK a good passive set up with the correct springs will be fine for me

I am sure tractive are good but on a road car in the UK a good passive set up with the correct springs will be fine for me Tractive's active is particularly good for a road 997, one can have extremely soft springing for low speed crappy roads with the damping giving extra assistance and control when needed and multiple damper curves which are selected on the fly, it is revolutionary for road cars hence why they all have some form of it from the factory now.

Think that's a subjective call. The sort of solution you talk about is certainly in vogue at the moment. But personally, really, really dislike setups with soft springs and increased damping to compensate. For the road, I much prefer firmer springs and just enough damping to control the them. The opposite, in other words. Hence, don't much like PASM and similar active setups. Current have a 9x7 gen 2 car with PASM, and tbh I think it's pretty crap. 9x1 cars are a bit better, but still don't like them. Personally don't think you need soft springs for a reasonable ride on UK roads. It's damping that causes most of the ride issues, in my view and experience. Not springs. Which isn't to say that's the 'right' way to go, just that there are alternatives.

I get tractive at end of the month via 9e. Can't wait!

Ohlins or Nitrons would be my choices. And please accept my apologies for having briefly derailed your thread earlier on

The ps9 are a good damper, it’s springs and the ride had settled, may be getting cool bound so raising up next week. This is too low

Not weighted yet will get it on the scales

Hi Jeweller70 Just wanted to chime in and say how stunning your 997 build is… colour choice is perfect. Obviously I’m massively biased, as I’m extremely local to you, running a 996 Turbo (I think 1 in 4 ever made in UK in that exact green colour). Yours looks flawless in the metal though… makes me want to re-spray mine (added to project list!) By chance did you ever settle on your seat choice? I saw you mentioned Pole Positions as a consideration. I’m sure with your racing exploits you’ve done some seat time in Recaros finest, but if you ever wanted to wiggle into a set of Pole’s, I’ve got a set in one of my 996’s and I’m literally 50ft round the corner mate (how’s that for online stalking taking to new levels!) lol Seriously just message me anytime if it helps you. Anyhow my friend, genuinely lovely project… keeps my Porsche Project passion alive whilst I’m committed to house refurb and banned from any Stuttgart based thoughts! Best wishes, Nath

Nath went for Corbeau as I know the MD and don’t want to much bucket for the road. Pop round you can have a drive....

Jeweller70 said: Nath went for Corbeau as I know the MD and don’t want to much bucket for the road. Pop round you can have a drive.... Hi Marcus, You’re too kind. I would definitely love to pop round soon for a chin wag and admire the project. Really interested in a few points as they’ve been on my ‘project list’ and it’d be great to get your thoughts on what you’ve achieved. Speak soon (in person!) Best wishes, Nath

Initial Dyno reports in after run in. Fully aware all dynos are different. They key is the difference not the absolute number We are comparing to a base run an standard low mileage C2S 3.8 (standard 27k miles) The 3.8 gave 330 hp Our 3.9 gave 351 Torque is the biggest gain with 30hp more from 3k and 35hp more from 5k. There is more to come as pre cat lambdas need to be renewed as not reading well. We feel 370 will be possible and 40hp up in the mid range Will post the charts when we do final runs. Fixed ride as well with raising ride height by 15mm

Goes off to look at 997 cars for sale...

OP, Just wanted to say I absolutely love it, congratulations on an epic car. I think the colour combinations of the exterior and wheels with the retro interior are really classy. Looking forward to future updates.

I did it on the 996 airbox first and it improved the sound for almost no outlay, the 997 is about the same I would say but I also had a 3.9 engine which makes a slightly deeper note anyway

Thanks, I'll try one out then.

Back with some updates Fitted Tractive and had more dyno time, suspension is very good and we have another 20bhp at the top end with new O2 sensors and a remap Going to redo the interior sold mine and have a back dash and new black carpet set to go in. Got some new retro bucket seat frames and looking at Cognac with black accents, and retrim the whole car
