Porsche Cayman S Engine - Gen 1 987.1 M97 vs Gen 2 987.2 MA1 (9A1) Why is the Gen 2 so much better??

[@andrewradford1334]

I didn't realise that the engines were so different between the generations - I always thought it was just the management of oil being pumped "better" and the IMS bearing was redesigned!! Great, informative video. Nicely done chap.

[@512TXSDIY]

Your white Cayman looks great!

[@jongib6096]

The 987.2 definitely carries a premium over the 987.1 but I sleep easier at night ;) Great video sir, thank you!

[@sanjinuravic856]

In your review you should have pointed out that updated M97 engine has very improved IMS bearings. I'm the first owner of 2007 Cayman S (90 000 km) and I didn't have IMS failure or any other serious issues but at this moment my car is at service and I'm waiting for the following parts to be replaced: AOS, alternator, belt, belt pulleys and tensioners, water pump, coil plugs, spark plugs, rear brakes (1st time change). This is the biggest maintenance so far but after 90 000 km and 14 years it's to be expected.

[@NewArt1]

Having done many mods on the m96 engine followed by a couple of teardowns of the same blown up ones, I skipped the m97 series and went straight to the 987.2 3.4 DFI engine (which I haven't touched!). Thanks for this clear and well illustrated comparison! 😎

[@pl1068]

How’s the carbon build up on the inlet valves?

[@theawakenment1361]

I have a 2006 987.1 and it has the stronger ims bearing fitted as (factory) standard. The weaker ims bearing was discontinued in 2005. Saying all gen 1’s have the weaker ims bearing isn’t true.

[@The-Other-F-Word-Finances]

@Life Is Good Just turned 86k miles, only issues I've has with her was an AOS replacement, water pump was done at 40k miles before i bought it with 43k miles on her, other than that, been very strong mechanically other than normal wear and tear. Shes my daily driver and make most sure that I keep up on oil changes every 5k miles, and just drive her as she was meant to be.

[@alkoenig8519]

I have a 987.1 base Cayman from 2008 and 160.000 km on it no issues at all drive it every day also in winter these 2.7 engines can run easily 300.000 km no IMS issues whatsoever these 2.7 engines are the best ! No bore scoring at the 2.7 engines never !

[@ginotremblay739]

2006 cayman S 90 000 milles, no ims bearing problem, bore scoring maybe.

No issues with my IMS bearing. Worst thing has been the water pump at 40k and now a drooping headliner.

For over three years I have been getting conflicting reports mainly from my techs re any IMS issues with my 07 987 Cayman S. Having gone down that slippery apex with my 02 Boxster S and paying out a large sum to update the bearing what you stated is the best news.

Excellent videos, I love the way you present the info so needed by Porsche owners. Keep it up. Please tell me; is the 2.9 engine (in the 987.2 base Cayman ) more prone to problems than the 3.4 (987.2) in the Cayman S.

[@GarageTechAutomotive]

@@sg4682 hey, thanks for the comment, from my understanding I don’t believe it’s anymore prone to problems, if anything slightly better as it has indirect injection so doesn’t get as much carbon buildup.

[@sg4682]

[@weed46]

You car has in the improved IMS bearing.

[@I999-g2s]

I had understood the the .2 engine was essentially bullet proof. But, went to check out a 2016 Cayman 2.7 for a friend. For sale at a local Porsche dealer, with 30k miles and huge gap in servicing (no oil change for 2 years and 20k miles). Rattled on idle quite badly. So I took an audio recording and sent it to a 911 engine specialist - he was certain that it was due to bore scoring and advised that we walk away. I was very surprised. Now considering a 2015 S which sounds ‘night and day’ different.

[@Driftuner]

Would love such a video comparing the 2.7 to the 2.9

[@y0ungj0m]

Thank you so much for the wealth of knowledge! Been considering one and knew about no IMS on the gen2 cars, but not all the other things you've mentioned!

[@lifutian811]

thank u very much ,love from china boy. wish i own a 987.2 in 2025

[@ampark09]

A lot of people prefer the .1 cars. They are rawer and many would say the non-DFI engines sound better. If you have an 06 or later car you're not really going to need to worry about the IMS. And the .1s are much better value.

[@allthingsaudio3840]

What did they improve in the 06 for the IMS?

[@bhopindermahal6481]

The main advantage of the gen 2 the engines is the elimination of the issue of bore scoring which was particularly prevalent in the 987.1 4.4 Cayman S engines. The base 2.7 engines didn’t suffer anywhere near as much as the 3.4. IMS issues were more of an issue with the 986 and 996 engines.

How many kW does the 2nd variant engine have in the Cayman S.? How do I know as a layman engine variant 2. MA1 ?? Thank you

[@White1404]

Hi, I enjoyed the vid v much. I have one question. Can a Gen 2 987 Caymen, with no Limted Slip Diff be retrofitted with an LSD? How difficult or easy is the job?

[@GarageTechAutomotive]

Hey, yes they can, will need the gearbox removing and a new Diff/LSD fitting. Not a job to do at home unless you have room and also some of the measurement tools to ensure correct fitment.

[@richfixescars]

Thanks great video, makes me pleased I have a 2.9 Cayman.

[@niallanugent]

2006 987.1 Boxster with 110k kilometers. Small wiggle movement on tach at all engine speeds and bit of smoke on startup. Isolating the AOS solves the issue (appears to be failure inside AOS). Part purchased and ready to be replaced. No oil leaks. Bit of water inside cabin solved by replacing inner door skins which come pre installed with gaskets. Otherwise car is mint and drives great.

[@whateverrrrrr123]

could you do the comparison between the 2.7 vs 2.9 and 2.0t (all the base model)?

[@MrComvalRacing]

I have an engine failure on my 987.1 cayman s. Considering swapping the complete drive train to a 987.2. Do you see any major issues with this? Thanks

[@andywu593]

Great video! I've been thinking about picking up a 987.2 base cayman. Not much information on the engine is online but i heard that all porsche 6 cylinders share the 9A1 basic architecture. Does this mean with modifications I could convert my port injected 2.7 in the base cayman to the direct injected 3.2 in the s cayman? Or eve (theroretically speaking) the same engine as the 911 GT3Rs??

[@GarageTechAutomotive]

Hey, without looking into all the technicalities, I’d say it would be easier to do a straight engine swap. I’d suspect the cylinder heads will be different, plus you have a high pressure fuel pump etc. different ecu, wiring. I did a video on the difference between the 3.4 , 3.6 & 3.8 . They are more similar than the base and a S

[@brutallyhonest9140]

The Gen 2 is almost double the price of a Gen 1. The failer rate of a Gen 1 does not justify paying double the price. Only a person who has money to waste would think that paying double the price for something that never really happens is a good investment.

[@Dholi1]

That's what people say until it's you that has to face the bore scoring, IMS, or oiling issues. A low chance of failure doesn't mean it never happens.

[@xkitejunkie]

Super interesting and helpful thanks!!

[@HellaRandomVideos]

The new engine design is far superior.

[@steverichardson6920]

I thought the primary reason for having the IMS on the earlier motors was because Porsche saved money by using the same heads for left and right banks which meant the cam wheels were on different ends requiring the IMS to drive the cams at either end of the engine……..

Very informative, thanks.

[@1ROCKY89]

I bought a 987.1 and I’m glad I did it’s awesome. 35k miles and no IMS work. My question is what will happen if the IMS fails? Does that mean I need to purchase a new engine for $10k or so? Is that the worst case scenario? Or am I just wishful thinking because I enjoy driving this car so much lol thanks in advance for any reply see you out there Porsche brothers..

[@thedudeabides1443]

The likelihood of the IMS failing is exceedingly low but yes, if it does happen, your engine is toast and will need to be replaced.

Great, I’m not gonna worry about it at all, what a car for driving anywhere with turns, this is my 4th Porsche.

[@Sank1982]

I have a 897.1 had it 3.5 years with no problems. IMS is not a problem on Caymans they have the larger bearings. Regarding bore scoring I had mine scoped at purchase which was total clean from bore scoring, I have regular oil changes and services. Mine as been super reliable. Also Gen 2 are also showing bore scoring now so not a bulletproof as people thing. The only reason Gen 2 are holding the price better is because their newer.

[@s4ms0n1t3]

Gen 2 base seems to be the sweet spot of reliability and performance

[@HellaRandomVideos]

Yes! 3.4 vs 3.8 please! Thank you

[@pjay3028]

The reality is that a 997.1 Carrera S has a totally reliable IMS bearing and if you can get a car with Nikasil coated cylinder liners such as fitted by Hartech in the UK, you have a completely reliable engine that will not get IMS or bore scoring problems. This has the further advantage that the M97 has more of the traditional noise and characteristics of a 911 which unfortunately the MA1 lost. I would argue that a Hartech rebuilt M97 3.8 S engine is pretty much the best NA engine you can get in a Carrera. Buy one while you can!

[@michaeledwards5241]

The only problem is that the cost for the 3.8 engine is £11,000. A revised IMS bearing, new liners and pistons is £ 9,000 from Hartech. You will end up with a fantastic car if went down either of the modifications/ repairs but cost wise, a gen2 is the safer bet.

[@pjay3028]

@@michaeledwards5241 that's why you find one for sale that's already been upgraded. For some reason they're not much more expensive than standard cars... At the moment! Surely that's going to change?

[@GarageTechAutomotive]

Thanks Uncle Sam, the 2.9 is very similar, only it doesn’t have direct fuel injection

[@stephenauty2402]

It's not "so much better" it's slightly more reliable I suppose but the Gen1 is fantastic and failure rates are very very very low. Also you can buy a Gen1 for about 30% less (like for like)

[@Dholi1]

It's much better if the second generation doesn't experience IMS, bore scoring, and oiling issues. Those are 3 major issues. There are KZbinrs with the 987.1 S that can't even track their cars because of oiling issues, even after spending thousands on a deep sump.

I think you will find there is much more to bore scoring that you explain in this video. The move away from Nikasil coating to a much cheaper coating is the pivitol reason. Bottom line, there is a very high probability all MK1 car will suffer from this complaint.

Yea I kinda wish I got the gen 2. I don't really care too much about the IMS since it was absurdly low failure rate even on the 987.1's, but the bore scoring has me worried.

Nice to have a update, how is the car

[@MrSlowestD16]

@@newpatchincoming6574 Eh, well no signs of bore scoring yet, but I've also put maybe 500 or 1000 miles on the car since that post. I have like 5 cars & a few motorcycles, and that + work from home due to COVID means I barely put any miles on anything the past few years. Probably like 6k/yr total. I still have the same opinion, the car is worth like 20k, it's hard to justify 12k or so for an engine if it fails, but a 10k loss also sucks, so it's a pretty big weak point. The internet probably makes it seem more common than it is - you don't hear about the many instances that don't have bore scoring, but it's something I'd rather not deal with. I'm going to sell it soon, but I think even if the bore scoring issue didn't exist I'd be selling it soon, rest of my stuff is newer & faster and it's an extra mouth to feed in terms of reg, insurance, oil changes, etc. if it's not being driven much.

Two years after my first comment, I have now owned 3 Cayman S's. All manual cuz, duh... An 08,11,06 in that order. I prefer the looks & sound of the first Cayman. Even the designer Pinky Lai says there is only ONE Cayman. I was also fortunate to own a 997S & Cayman S at the same time and I can say unequivocally that comparing the Cayman & 911 is extremely foolish as they are completely different but equally brilliant & I can guarantee you will giggle with joy driving either car. If the 3.4 ever blows up in the Cayman, I will absolutely replace with a 3.6 or 3.8. If I could try & put it into words, I'd say that 911 is the best example of a true sports car, & the Cayman is a brilliant, but underpowered, race car. BTW, the chicks don't know the difference----in the words of the great Dave Chapelle----GOTCHA BITCH!!! PS A young man pulled up next to me at a light in a BMW.

Wrong, I have 2 Caymans a 987.1 CS and a 981 CS. There is nothing to worry about with the 987.1 if you are smart and know what your doing. The 987.2 also have reports of the same “issues” by the way. I spend a lot of time around Porsches and these issues are blown way out of proportion, especially by people who never own them. Every Porsche model has its “things to beware of” If I listened to experts on the internet I never would have bought my 993, 997TT or my R8. The 987.1 and .2 are still one of the most fun cars to drive. Bore scoring affects less than 5 percent of 987.1 and IMS less than 1%
