Amazing info. I keep learning more and more about the differences between the gen1 & gen2 cars. I owned an 08, & now a 2011. Thx for the video

Love the details and the diagrams. Always wanted to know more about the MA1 and Auto Journalist never get into details like you have here. Great video! Great topic. (I've had my MA1 for 9 years and love every minute behind the wheel!)

This is such an amazing video !! Good job .. that is some epic knowledge and detailed explanation

Decent review , nice to hear about the engine's rather than the usual Cayman reviews 🤙

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!

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.

Your white Cayman looks great!

Very well explained, makes my decision easy which generation I'll be picking.

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! 😎

Absolutely brilliant video, thank you

thanks for the video, i like that you explained what those differences mean

Great video ! Just over the moon I have the gen 2 Cayman 2.9 six speed box. Without doubt the best car I will ever own ❤️

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.

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.

Really an interesting video!!!! Thank you

Super interesting and helpful thanks!!

Great info thanks GarageTech. I knew about the IMS and seal which is why I steered clear of the 987.1 but good to know of all the upgrades and re-engineering that went on. I adore my 2011 987.2 Cayman S which I've owned for 3 years now and plan to have for many more.

Great info man. I'm looking into buying a 987.2 great stuff!

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

Very informative, thank you

Great video! Since you asked ... how about a deep dive on all the differences between the 4.0L NA engine in the 982 GT4 and the 9A2 EVO engine on which it is based? Differences between the former and the 3.8L NA in the 981 GT4 would also be interesting. Thanks!

Can you please make a video regarding carbon buildup on the DFI engines? Thank you 🙏

great info thank you for sharing it!

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.

Would love such a video comparing the 2.7 to the 2.9

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.

Yes! 3.4 vs 3.8 please! Thank you

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.

2008 CS..no issues here. Tuned and having a blast. Steal under 20k...good hunting

thank you sir good info question: what about the Cayman 981 engine, is that same ?

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

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??

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

Great video, I always wondered if I had to replace my 2008 987.1 engine, would the newer 987.2 M engine fit in its place?

I have a 2007 cayman s 987.1 with 92 000 miles with the original ims bearing, i drove it for 7 years no problem at all. I live in Morocco there is no possibility to get the ims bearing changed...

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. The car has been rock solid reliable to me but I've only had it for about 1.5yrs. Def. worried about the bore scoring though. Especially so since I have the "S."

@@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.

I have a Supra though which pretty much fills the role of that car exactly (2 seater, it's faster, '21, better in the twisties, still under warranty, etc.), so it's hard to justify keeping it specifically because of that car. I've been saying I'm going to sell it for a year though, so talk is cheap, lmao. We'll see when I actually sell it.

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……..

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

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.

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.

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)

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

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.

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.

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.

Direct injection, a ticking time bomb 😬

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. He yelled "Hey man, I love your car!" to which I replied, 'Thanks man!' He then said 'All us guys driving beamers want a Porsche' I smiled and replied "All us guys driving a Porsche want another!'

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%
