i really wouldnt mind having a 928 but it would have to be a 5 speed- they sound awsome but ive never driven one. I imagined they would be like my old supra turbo but a friend of mine said they are way nimbler and lighter than my 3600lb supra- surprised me! They are not much heavier than a turbo! Theres a guy here locally that my dad met w/ a 928 track car- but he pulled the motor(running) and swapped in a chevy motor claiming its "more reliable and cheaper to fix". blastphemey!

Buy a 5 speed. The auto is no fun to drive. Even the 79 928 with a 5 speed has 951 horsepower and much more torque with none of the lag associated with it. It does weigh about 400 pounds more.

If I ever get a 928 it will be an s4.

Everybody who has posted here has it wrong. Now that I have your attention:

There is NOTHING wrong with having an NA in college. It's NO slower than a Scion or other popular college-kid car. Sure, I'd like another 50 horsepower...but friends with Fox body Mustang 302s who drove my car refused to believe that I had a 4 under the hood.

Don't forget that the 32v 928 and 951 will require premium gas. That's an extra few dollars every time you fill up...it snowballs.

I seem to recall that you posted about having trouble paying speeding tickets you racked up in the 944...how much worse is it going to be in a faster car that costs more to maintain?

Get your education, save your money. In <10 years' time, I'll be able to easily afford the car I want (pre-99 911). I think that's a whole lot better than having to worry about a fast, trouble-prone 20 year old car in college.

If you think I'm posting this out of jealousy...the past 2 summers' income for me, properly saved, could've purchased the $7k 67k mile S2 I found for my uncle, maintained and insured it for a couple years, and taken it to a DE or two.

A $6-8k 928 is going to be a 1979-1986 model, or a very tired 86.5 - 90 model. You will not find a late model(S4) 928 five speed for that price. You're much more likely to find an early 928 five speed for that price. All 32 valve engines are interference. All Euro engines are interference (have XXX in the VIN). 16 valve US 928s are not interference AFAIK.

The level of support for the 928 on these forums, and from various suppliers is fantastic. We have many owners in Canada too. The best search in your price range is prolly the S2 from 1982-1985-ish. They have a later style fuel injection (not CIS) and better gearboxes. If you find a Euro 928 from 1982-1985, that has 300HP, is not too heavy and has the S group body options. I know where there is a rough one for sale for under $2k, would need a lot of love.

PPI for a 928 is a must. And it should be done by a 928 savvy person. The TB and water pump change is well documented, and not difficult for the DIY if you take your time. They are comfy for long distances, and can be very fast at the top end. It is not a stop light racer. I don't even know how to spell 951 so I won't compare them.

I've had some turbo cars that never needed repairs too but I think by and large you have to agree: The turbo system adds failure points and complexity, and underhood heat. The turbo, wastegate and boost control solenoid never fail on an NA car. 's truth.

my old boss at work had a 951 and it also burned lol. I guess that is a easy preventable fix though by just replacing your fuel lines which doesn't cost that much.

before I bought my 944 I was looking at some early 928s also and both the early 928s with 5speed trannies I looked at had bad synchros so grinding.

one of them was being sold by a guy that races 928s and he told me that pretty much all the early 928 5speeds have bad synchros and will grind gears.

not sure if that is true.

yeah the early 928 still has 220-230 hp. with a nice exhaust the 928 sounds pretty sweet but I like the look of the 944 especially the 951 better than the early 928s. the early 928s can look better with boxster wheels / a spoiler.

Jeff did replace the fuel hose not too long before his car burned while he was driving. He drove the car while it was smoking because where his car burned he could not pull off to the side. Then he finally got out of that tunnel under the Long Beach airport and watched it burn. He no longer posts because he sold his Callaway 944 and his 85.5 944 and bought an early 911.

Early 928 that is raced will have bad synchros. My friend's S4 does not but had to replace a bearing one time. I had a 79 with bad 2nd synchro from the owner before me who was a strip club manager who knew about as much mechanics as Tony Montana.

damn that sucks about the 951 burning down. Seems like it's actually pretty common.

think I'll look for a 16 valve 928 this summer. I want to buy one from the Seatle area, (I'm in vancouver Canada) as they are cheaper down then I have to figure out how to import one into Canada.

probably hard to find a good 5 speed early car. Most 928s are automatics. An automatic porsche just seems wrong...

thanks for the comments.

Sad when people talk without "facts" there was a poll on the OT forum which is only for paying members about Porsches reliability here are the facts:

There was a total of 105 guys from the 928 crowd that entered the poll
only 61 stated that their 928's were running and 41 stated their car were broken down.

Out of the 58 guys from the 951 forum 50 stated their cars were running and only 8 reported their car innoperable.

That's 11.61% of 928 broken down and only 2.27% of 951 that weren't running.

Here is the link for the paying members.

Also there was a thread in OT about burned Porsches and I saw 928's on fire but no 951's, but I know for a fact that the fuel dampner hose burst frequently on the 951's.

Also there was a significant thread on the 928 forum about a magazine that stated the following:
"ANY 928 IS A CRACKED BLOCK WAITING TO HAPPEN". He goes on to say "the 928's reliabilty issues are now so well documented there are tribes in the Congo who still think the world is flat but understand that any 928 motor is a cracked block waiting to happen"

Let me state that I drove my 951 for almost 4 years at boost levels from 21psi to 23psi withouth any reported problems, that block from my car was used by special tool to achieve 540rwhp in his car.

here is a link to the thread if you don't believe me.

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.

lets face it any porsche can burn and its happened- i put a hood on harry's 912 that was from a nice 911 that burned from a cracked fuel line. The hood had the paint bubbled on the rear edge- it went up pretty good! Most of the 951's ive seen burn all the way were from leaves shoved up under the bellypans starting a grease fire. Yeah there have been plenty burn from the fuel jumper but there was a recall and people refuse to replace the line because its $80 - first thing i do an every car i buy- three or four by now.

Bingo.

My 928's have been far more reliable than my 944S and plenty of 951's my friends own. I also know people who have 928's that are complete basket cases.

Let me know when you find a cracked one. So far 24psi has not been an issue.

Sure run it dry of coolant something will probably crack. Try the same thing with a 944 block

Let's try it again with a public poll and see how the results change.


Quick Reply: which is more reliable, 951 or 928?
