964. Time to shake her up a bit.
Discussion
Extra power doesn't have to cost a fortune. It's quite common to find pitted cams and rockers when these motors are stripped probably due to modern oil and the low zddp levels. My engine needed two cams and several rockers, two aftermarket cams cost less cost than one new cam from Porsche. Other small mods done during the build added up to a much stonger engine.

I'd keep the engine standard providing the compression test comes back good. These engines offer a poor bhp reward per £ spent. I'd drop the engine, change to a LWF and change the clutch while you are about it. These cars respond well to weight savings and sharper brakes and suspension. My build is on here somewhere. It may prove a useful source of information.
Good luck - and dont forget to keep all of the bits that you remove during the build
Thanks Steve. I will read the thread on your build with interest.Good luck - and dont forget to keep all of the bits that you remove during the build

Interesting. May I ask who did the work on your car ras62?cornershop said:
Thanks for that. Like the idea of throttle bodies and this seems a good bolt-on alternative to the full set up. Might give Crawford a call.Lungauer said:

Interesting. May I ask who did the work on your car ras62?Throttle bodies a waste of time and money imo. Great for max power but at the expense of usable torque which is exactly what a road car needs. If you're ever up around the Cheshire area you would be welcome to try the old girl.
Missed that ras62 but thanks - and thanks for the offer of a drive. Would love to if I'm up your way.
Spoke to Chris at Fenn Lane Motorsport yesterday, who seems to be the nearest of all the suggested specialists. As an earlier poster said he was very knowledgeable and keen not to spend other people's money unnecessarily, a rare and valuable commodity these days. He suggested a compression check and if there is a problem using K-Line bronze liners in the valve guides. Anyone have any view on whether this would be a good solution or would it be better to have the engine out and replace them entirely?

Depends on the rest of the spec IME, as ITBs alone won’t dictate where the power or torque is created. Eg below, not mine, but a 3.2 short stroke using motec and the same ATPower ITBs i posted before. Absolutely not peaky and a flat torque curve:
Firstly, thanks Steve for your kind offer. It may be difficult as I'm on the other side of the country, though I do have family in north Essex which is not too far from you.
Also apologies for not replying sooner but I've been suffering from some existential angst about the 964 which has led down a not entirely smooth path...
Buoyed by all the encouragement on this forum I decided the first thing I should do is get the health of the engine checked on the basis of establishing a starting point. So I booked it in with Fenn Lane Motorsport and spent a happy afternoon with Chris Lane discussing all sorts of car related stuff while his engineer did a pressure test and whatnot. Happily the car was deemed strong and Chris's advice was to leave it alone and mod around what we had.
It was rather too easy to get carried away with everything he could do. Throttle bodies, lwf, remap, exhaust, stripping out sound deadening, bucket seats, sunroof delete, removing side impact bars from doors etc. etc. This gave me pause for thought because the danger was that the car would become both too far removed from original and uneconomic when looked at purely in terms of investment (which possibly should not enter into the equation). It may become better but would still never be an RS.
Now I had very fond memories of a Cayman R I had back in 2011 and it occurred to me that this car did pretty much everything I was looking for a modded 964 to do straight out of the box. Relatively light weight (GT3 doors, buckets etc), enough power for road use (330bhp), LSD and so on. Well the long and the short of it is I bought one, somewhat impulsively, and so was back to two cars.
At this point I convinced myself that two cars was too many and that a softening market meant that the 964 should go. And this is where things get a bit sticky. I mentioned to a well respected dealer that I was looking to sell and, after sending photos and some detail, he suggested it might not be the best time (he also had a couple of 964s in already) but that he would bear it in mind if he got any enquires.
Doubts were now surfacing about my decision and with winter approaching I was quite glad that nothing was likely to happen. Needless to say the fates intervened. The dealer had a call from someone looking for a dark colour manual 964 which he was planning to put Fuchs wheels onto. Mine being black and with these already fitted, suddenly the car was provisionally sold. With an increasingly heavy heart I dug out the files of history and gave the old girl a clean prior to the dealer travelling to look at the car. On the brake-drying drive I realised I had made a terrible mistake. The car was manufactured the year my son was born, was my daughter's wedding car and once gone there would be no way I would be able to get another I liked as much. Having agreed verbally to sell decided I could not go through with it.
Pulling out does not cover me in a great light, I know. I would stress that no money had changed hands with me - the car had not even been viewed, nor was anything signed. However two parties were let down and for that I am sorry. But what else could I have done? Gone through with a sale I didn't want just to keep the other parties happy? At the moment I've decided, not for the first time, not to mod the car. The CR will be the b***s out hooner and I'll continue to enjoy the 964 for what it currently offers.
Sorry this is a long and rambling post. Probably I'm looking for some affirmation that I haven't been a total heel. The jury, I suspect, is still out.

I so nearly bought a black / grey trim ( dire trim colour ) J reg 964 in 2006 in the west country. It was up @ circa £13,000, but it was cosmetically scruffy, so i walked.
During the summer months i often see a red 964 which has very obviously been “ tweaked”. Looking forward to coming up along side him in the Griff......

I was reading this and was taken back to 2002 when I first got my 964 C2.
In respect to mods sure you can blow a lot of money getting it to go slightly faster but based upon my own exprienced my recommendation would be.
1) remove the Cat, replace the middle silencer with a Cup pipe and retain the final silencer (assuming you don't want to track it) - mine produces 108.5db at 3000 rpm.
2) fit a KN filter - don't drill the airbox.
3) lower the ride height and have fit stiffer springs (I used Turbo springs)
4) fit a strut brace.
5) get it chipped - mine has a Ruf chip
6) Fit 993 or 928 4 pot calipers to the rear.
7) Install a LW flywheel and Clutch - this is by far the best mod ever 😀
8) I removed over 25kg by going on a diet - cheaper than a set of Pole Positions and new interior, thinner glass, etc. More weight reductions are planned with the removal of the rear wiper and AC unit - because I use neither. I would like a rear seat deduct, but not convinced that the performance would improve significantly.
Currently the car dynos at 289bhp and with the dropped ride height feels and handles like a go cart, hence 70mph feels like 100mph. 110mph+ feels scary. It's not exactly comfortable but for a weekend hoon, it's a blast.
Good luck with your project.
