I bought the car with the kit already installed. I'm just going through the car to do what I can to get it sorted out and running well. I've reached out to them and they directed me towards the right plugs and coils to get. Car only have cyl misfires on cyl 1, 3, and 6. I'm waiting on the bosch plugs and beru coil packs to come in to install them and see if the codes clear up.
07 Cayman S TPC Turbo Kit - Engine beeped and blinked for about 10 secs. No codes though.
The car had multiple misfire codes so I went ahead and installed new spark plugs. NGK #2667 BKR7EIX gapped them at .028”. Cleared codes and went for a spirited drive. The car ran fine and on the way home, I heard a beep and the CEL light blinked for about 10 secs then went away. Drove her carefully home close by and scanned for codes. Showed no codes. I had the dash read the oil level meter and it showed about half full! I just ordered an oil change kit as well as an air old separator to be safe.
Do you guys know what that CEL meant? I hope I didn't damage anything with the low oil level =( I also have new set of BERU coil packs to install. Any ideas or inputs are greatly appreciated. Thanks guys.

Yeah, good plan. I am waiting for the oil change to come in and I will be inspecting for those things when I change the oil. AOS is also ordered so will inspect that area too. Keep posted guys. Thanks for the replies.TPC would be happy to talk with you about the codes, HA HA. Change the oil and cut open the oil filter to see if there are any engine parts in it. No engine parts, then plugs, coils, AOS and new oil. Let us know what happened. .
Unfortunately, yes. I took a chance since it was priced fairly decent. So hope it turns out ok fingers crossedRegarding the turbo, OP says he bought it this way, I hope "this way" doesn't incliude a known flaw previous to the sale.
lol the turbo kit was the reason i bought this car....we will see how it all plays out...if it doesn't pan out the way i want to, then i'll just have to get rid of it and take the hit. we will have to wait and see.If you get things sorted out and the motor is happy, I’d really consider making it happier and take all that off..
Good point. I’ll have to check with tpc how ouch qt for oil change.It needs or should be on the level… don’t mess with that one… so I’m asking how much more oil does the motor hold since adding the turbo? You have lines, a turbo.. and maybe an oil cooler?? You can’t do an oil change at oem specification and expect the level to be at the top…
Ok. Just installed oem plugs and oem coils. Seems a bit better but still hiccups at idle warm up. Haven’t driven car yet. I will tomorrow but still showing misfire cyl 1 and 6. 🤬
Not driving it at all. Just trying to troubleshoot the car. Yeah, it hiccups at idle. As soon as I drive it out of the garage, I get a CEL misfire codes and currently its cyl 1 and 6. I haven't looked into other components yet. The car is running at around 5psi when I drove it last week. That was the only time I have driven this car since it was delivered. Should I just drop it off at a shop? I don't want to be playing guessing games here. Just want it running right so I can start to enjoy it....Hiccup, so it hesitates? Have you ever check those injectors? How about the fuel pump? MAP sensor?
big question, how much boost? Probably need to stick
An A/F ratio guage…. I’m really guessing here without knowing your A/F. Be careful if you drive that right now… no kidding
Yeah, that sounds like a lot of work. I already cleaned the maf but I will install a new AOS tomorrow and clean as much carbon build up as I can. I'll report back. Thanks for your replies..That would be the best idea however determining if this is a TPC issue or a bad component issue could take some time. You have a trusty tuner/dyno shop near you? It’s probably “hiccupping” because of the misfire (unburned fuel)… so that require to hooking it up to live data… this could take some time so be patient… if it was me and wanted to keep the turbo, I’d take it all off and go back to stock…
See how it runs stock…
Then circle back around… ton of work tho…
The car already has a defi boost gauge. Thanks.My last car was a 987.2 CS w/ TPC turbo kit. I bought an AutoGage boost gauge but sold the car before installing it. I'll make you a great deal on it if you want one.
So UPDATE...
Car seems to just misfire during idle. No CEL at all today but the misfire shows in the scanners live data. Car drives perfectly fine. What's up with the oil light meter on this thing?!?! Measurement is all over the place. Sometimes, 1 bar only, Sometimes at the middle. Today, check engine oil level light came on when I pumped some fresh 93 octane. I didn't want to risk it so just bought 2 qt at the gas station to be safe. Then when I started the car, it struggled to turn over, low oil pressure light came on and shut off. I tried again and it started to idle ok with no warning. Drove it carefully home a few miles and then when I got home, I checked the oil level and the meter says full bars! How do you go from no oil and pressure in the engine to full with just 2 qt?
I'm going to change oil tonight but this thing is making me all confused....

TPC still exist as far as I know. I do reach out to them for some questions. Sometimes they reply, sometimes they don't. I didn't get a chance to change oil tonight but I will tomorrow. That way, we can make sure that the right amount of oil will be in there. I am still waiting to hear back from TPC if the oil capacity has changed from stock. For now, I'll just put in the stock amount.Stock setups don't usually bounce around the level that much. My guess is that this has to do with the TPC setup. The car was built with a certain range for the oil level, and I expect that's no longer valid or appropriate for the TPC changes.
Still, FWIW, the stock setup on a 987.2 says it's about 0.42qt per bar... so if you put in 2 quarts, that certainly seems like WAY too much. Again, not knowing what TPC did, we are just guessing... but if you did that to a stocker, then you're likely well into overfill and are risking damage to the AOS (new or old).
It sounds to me like this is not something you have the desire or ability to work on, which is fine. But it's going to be an expensive proposition. Like others said, if you really want to keep it, I'd pull the TPC stuff off, as it's a big risk without having the support you need. Alternatively, if you can find a shop willing to tackle it with this stuff, then have at it. I imagine most won't want to do this... and if they do, it's going to be expensive simply because it's going to take a good deal of time to figure out what's going on, without proper support from TPC.
I'm coming into this blind - does TPC even exist anymore? Can you contact them for help at all? From what I have read "between the lines" they aren't around?
Just changed oil. The oil sump looks stock. So just filled it up increments until I got the oil bar just shy of full where there’s 1 empty bar left but right at the top arrow.
here’s what’s happening. Car idles with a bit of hiccup (sometimes cel would come on with misfire codes, usually cyl 1 and 6) and runs perfectly fine and strong. However, during driving, CEL would blink about 10 times and go away. This happened a few times on way back after test driving car after oil change. Pull into garage and check codes now more cyl are misfiring codes and also o2 sensor showing up too.
Code 2231 short signal bank 1 sensor 1
and the usual 030x code for cyl misfire.
Should I start looking into other things like o2 sensor? Are the cats bad?

Yeah some plugs were fouled. I don't quite remember which cyl it was but it might the 6 cyl. Injectors might be next to look into. I'm trying to find a good indy shop here to trouble shoot this for me. Any link to how to replace injectors in these engines?When you changed plugs, did you notice any build up on plugs for 1 & 6 cylinders. Just wondering if its the injectors for those cylinders that have gotten their spray patterns changed, maybe due to the installation as they are port injectors.
Yeah. I'm leaning towards injectors. I also have been working on many tuner cars since mid 2000s. I have had many cars from japanese turbo cars to european turbo cars. I haven't had a car since 2018 because I was tired of working on cars. But now I got the itch again hence the current car. I am quickly reminded the pain of working on the cars because of things like these. You never get to enjoy the car but just spend so much time and money fixing them.....it never ends =/
I'm going to get the car looked at a local shop near me. I really just want to start enjoying the car so hopefully they can pinpoint it and just fix it. I'll keep you guys update.

Don't remind me. Thanks lolThat’s why I don’t work on them much anymore.. it’s not worth my time.. I haven’t had an import for 15yrs… well guess I had my V6 MR2 5yrs ago. I’ve always had two hobby cars… usually a Porsche and the hobby hobby car…
Anyway, injectors, good place to start… fuel pump too…
Good thing you bring up imports tho… because you could probably buy 10-15 used motors for the price of a Porsche rebuild… food for thought
I'm in Orlando, FL. Driver's Choice seems to be the go to place here but they said they don't work on non-oem cars.
UPDATE....
I changed the drive belt today with OEM PORSCHE belt. The old one was also OEM PORSCHE but not sure if it has been changed yet. Regardless, I haven't gotten any misfire codes! I was reading other people's misfiring situation and one post came about how they have seen many cars witth the same issue as mine be the drive belt. Where they were putting on non oem parts and causing issues. In this case, it was oem but maybe it was time for a much needed replacement.
I'm happy to finally gotten rid of the misfire codes. I'll update if anything changes.
