That magazine writer don't know **** about 928 engines so please do not use his words to make 928 sound bad. You have demonstrated time and time again that you can dig up other **** which will make any and all 928's sound bad purchase so use that data instead if you feel like you have to find something to make 951 look superior. And don't even bother responding anything about my comments of cracked 928 blocks in thread you give link to. I do have 951 block in garage too in which there is almost fist sized holes on both sides of the block. 928 is not only engine which has issues.
Have a nice day, take a chill pill and fix your non running 928
lart.

- They have the same valvetrain,
- Both have the same rod bearing issues (actually 944's are fare more prone to this over 928's).
- They use the same rod bearings.
- Neither have main bearing issues.
- The 928 clutch is far superior and easier to change than a 944.
- The 928 transmission (even the 5-speed) is far superior to the 944/951 trans.
- Are you able to do full launches with drag slicks yet Lart??? Didn’t think so. Nice R&P you got there in the 944. I have never heard of one going on a 928. Even with 700+hp.
- Electrical issues? They are both Porsche’s so it’s a draw.
- Both have the same water pump / timing belt issues.
- The 928 fuel tank is a bitch to change, so you got me there
- The 928 radiator is a bit expensive, so I hear. 100,000 miles on mine no leaks (knock on wood)
- Early L-Jet cars (with the barn door…) have the more expensive style injectors. I cannot remember the last time anyone needed new injectors, but I guess it could happen.
- When it’s time to change plugs / wires, the 928 will cost more since you are buying twice as many spark plugs and wires. $1.50 per spark plug I’m not losing any sleep over this.
- Doing a head gasket is a bit more difficult on an early 928 versus a 944, I’ll give you that.
- Head gasket issues are the same……almost the same gasket!!!
- Yes most 928’s are automatics. Both of mine are 5-speeds so why would that bother me?
- Synchros on the early (pre 85) transmissions are a bit weak. They are the same synchro on common year 911’s. 100k on mine still original. I chalk it up to people driving too long on worn clutches. Just a theory.
- Ball joints - tie with early 928's.
- 944’s do have more headroom (at least over 928’s with sunroofs)
So what issues are you talking about? Please let me know since 20+ years of 928’s under my belt I’m worried about these issues I’ve never known about happening to my car. Please save me Lart – please!!! I’m begging you!!!
I own both (ok, not a turbo).
When most would have parted their 944 out, I’m still putting mine back together. Why? Because I love 944’s.
Why do you have to be so negative all the time? It’s not healty.

928s will burn. That is true of any 25 YO car, I don't care if it's a Toyota or a Ferrari. 928sRus has a nice, low cost fuel hose kit that should be mandatory for every owner.
They do not crack blocks. The block and head of the 928 is about the most robust part of the engine.
As for the poll about non-running 928s vs 951 or 944 or whatever they are, I think this is prolly fairly accurate. There aren't many guys that buy and use a 928 as a daily driver. Non-running can be anything from a car up on blocks, missing lots of parts, to a car that's down for a new AC evap unit. The 928 is quite often a second car, or a weekend car whereas the 944 types are often the only means of transportation for many owners. I'm a good example. Last three years my 928 was my daily driver. It wasn't down at all. Then I did a track event and suffered the 2/6 rod failure. Now, it's down for repair. But guess what, I have a backup car and it's also a 928! So, I have one down, and one running. In a few weeks I'll have them both back up, and the world will once again be spinning in greased grooves.
The 928 is more complicated is some areas, but not extensively so. It is significantly more car than the 951/944 genre, as defined by both it's price, speed, and market position.

check this post by one of the guys advocating the 928 on this thread, ironic isn't.
I rest my case.
Judegement for the plaintiff.
check this out, I have not insulted, or attacked, or demised anyone, yet these guys are going to accuse me provoking the 928 guys, but all what I am doing is using their own quotes and statements against them.
I am out before the ban, have a great day gentleman.
I have two 928 blocks in garage which suffered serious cracking problems. At least one was caused by head gasket failure. This allowed water to leak into combustion chamber and was away oil film from cylinder wall. This in turn heated up piston which then cracked cylinder in nice straight vertical line either at 12 o'clock, 6 o'clock or both when looking cylinder from above on exhaust side. It seems on at least one cylinder crack started in middle of cylinder tower but did not reach all the way to the top. On other cylinders crack lower end is about same position while they get to all the way to top.

Good thing you are not a lawyer
Wanna see the four scrapped, beyond repair 944 blocks I have? Two from head gasket failure, the others from rod bearing damage.
Try again.
So if I take the time to dig up how many hundreds of posts where 944 engines failed that suddenly means what? It doesn't prove a thing and you know it.
EDIT - this took about 60 seconds:
Compared to a Peugoet?? Ouch.

What’s this? According to you a cracked 944 block isn’t even possible

A sad end to the 944...if you're faint at heart read no further:
After dealing with the overheating on and off all summer, and changing hoses, thermostats, etc...I got in the pcar today and heard a loud "click-click-click" sound as soon as she started up. Having just changed the oil less than a month ago, I got curious and checked it out. I discovered that the oil was now a brown muddy mixture of oil & coolant!
Basically the block is cracked and the heads are blown, and I've been told that I'll need a whole new engine! Since I can't afford to buy an engine that costs more than the price of the car, I have no choice but to send her on her way.

not to darken the mood buy 2 years ago I thought those were symptoms of my car as well, I changed the oil cooler seals and the problem returned. I took it to the porsche shop and I had a blown HG and cracked block. cost me 5 grand to get rebuilt! (drop in another motor if you can.)
How deep was the water? I would also be concerned with cold water hitting a hot engine block, causing a crack. Loss of coolant usually means blown head gasket, cracked block, etc. If you are fairly certain you pulled water into the cylinder, you could have compressed the water, and blown the head off-
Is it holding coolant now? Is the new oil turning foamy? I'm afraid it doesn't sound too good judging by your description-let us know what you find.

yeah, sounds like a head gasket or cracked head/block. more likely block if something's cracked, due to cool water on a hot engine/shock cooling. now, do what they said and contact your insurance about repairs, if you're on your own, start with the headgasket, and if its plainly blown (sounds like it, motor will run poorly and shoot white smoke if you're burning your coolant) you'll certainly be in for a less difficult fix than a new/rebuilt engine block.

There is a reason why fart951 is on my ignore list. He is argumentative and loves to insult people. His arguments never contain any facts. He's also famous for posting things and then deleting or changing them, along with his infantile photos.

I have 6 engine blocks in garage, one 951 and 5 928 blocks. Out of the 5 928 blocks 2 are bad and 3 are ok. This means failure rate for 928 blocks is 40% while for 951 blocks its 100%!!! There are 2 928's and 2 951 in out small garage together with one early seventies 911 and S class MB. One of each type front engined P cars is currently drivable, one 951 has gearbox and some suspension parts out. This means in both cases 50% of cars are unreliable. When engines in these friends cars are also included into count results are 2 dead out of 6 928 engines and one dead out of 3 for 951 meaning 33% problem rate for both models.
Just for the record, working 928 has SC and almost twice the hp compared to either 951, and those 951 aren't stock either. So 928 being stock NA isn't explanation why its still going strong at 120k miles with original engine internals. Last 10k is with 8-10 psi boost.

Sound reasoning.
As for the topic, they are both 80s porsches, subject to abuse and improper maintenance from the PO. Perhaps more 951s are running because they are easier and cheaper to work on. Just another perspective.

Todd (owner / builder of the car) has been unable to fit the proper sized turbo's for this much boost without radically modifying the car.
Not to mention the efficiency of these new blowers is so high, he’s not even looking into the turbo option anymore.
