Engine rebuild - taporite6 - 02-02-2013

It all started when i drove to vegas last year .When i arrived there my water pump broke

I have 200,000 mies on the odometer i think it was time for an engine rebuild

What a project, ended up costing upwards of $19,000 and growing

Runs better than before but like dominoes one thing leads to another transmission had to be

repaired i replaced all of my bushings to polyutherne rebuilt steering rack

Engine Transmission and Suspension are all better than when i first bought the car

Up next my interior replacing dash probally going with a colored dash as opposed to a black one

( i think it gives the car a more modern feel)

Just hope i never get hit from the front will be sad to see grown man cry like a little girl

Lol

Did you add any performance upgrades as part of the rebuild?

Engine rebuild - taporite6 - 02-02-2013

not relly but will get a chip next month

any suggestions

Engine rebuild - tbillow - 02-02-2013

Flash has super charger kits in stock.....

Wow...19k sounds like an awful lot for an engine rebuild. I take it you did not do any of the work yourself? Did you have the dealer do it?

Engine rebuild - flash - 02-05-2013

nope - that's about right if you have to pay a shop and they need to change out pistons and/or rods. it's maybe a bit high if they are reusing that stuff, but only about $2k or so.

Engine rebuild - hot968 - 02-05-2013

I am right behind u brought the car in April 2012 put 267 miles on it since then. it is a '92 has 63,000miles for $15,000. Have put in 12,000. so far for repairs some I did myself and some at the shop independent shop but Porsche specialist. These cars r money pits! BUT the joy of driving them in priceless <img src="/forum/images/smilies/968/clap.gif" class="smilie" alt="" /> <img src="/forum/images/smilies/968/EmoticonCar.gif" class="smilie" alt="" />

Engine rebuild - taporite6 - 02-11-2013

after i did the engine the transmission started giving me problems

next is my bow for the top ans seals

Engine rebuild - Oily - 03-12-2013

I'm doing an engine rebuild myself. Only part way through the project.

I am not a master mechanic, but time to do the work has been:

Engine out of the car - 5 hours

Ancilliaries off engine - about 2 hours

Cylinder head off and stripped ready for new valve guides, skim and reseat valves - about 2.5 hours.

[Image: 9March13489_zpsd42f1a6c.jpg]

Time wise, it will take me slightly longer to put back together, so say 30 hours in all. I am a beginner at this, so an experienced professional should be able to do this in less time?

The parts and engineering work will be about £2,500.

I hope you don't get disallusioned with the 968, they are very rewarding cars to drive.

Cheers

Oily

Wow, good on ya for tackling that yourself.

Engine rebuild - Lear35A - 03-12-2013

Heck, it can (should?) take 30 hours just to clean parts.

Engine rebuild - Cloud9...68 - 03-12-2013

Took me over a year (most of that time being waiting on the machine shops I used - good ones are few and far between in Austin, and have insane queue times)

I cringe when I read how much people spend for shops to work on these cars. Personally I can't imagine owning second hand cars and not learning to do the work yourself. These are fairly basic cars. Rebuilding these engines, or even a transmission is not rocket science. You need time, patience and the right tools, but those are hugely cheaper than what you spend on shop rates.

Do people accept these costs because they think spending this kind of money is all part of the Porsche mystique? $19,000 for a basic engine rebuild?? If you can afford it fine, but surely that type of money is best spent on new cars with warranties if you don't want to do your own work.

Engine rebuild - flash - 03-12-2013

you also need a LOT of very special tools, unless you plan to farm out steps. i've been building engines for over 30 years, and i know what went into mine. i did a lot of the menial work, and it STILL cost me almost $20k. granted, a lot was new parts that aren't a normal part of a standard engine rebuild, but i still spent about $2500 on machine and balance work alone. another tidy sum in the blueprint and flow work. it adds up.

sure, you can slap something together, but time is money too. it was a LOT less expensive for me to pay the builder his $140/hr than for me to turn down work at $400/hr.

i'm just saying

Engine rebuild - Dubai944 - 03-13-2013

Sure, I'm not suggesting everyone sets up their own machine shop. You of all people on here know full well what parts and machine services cost. And you know that if you were going to spend that type of money on a rebuild, and you have, you would make sure you bought the best parts you could and had the machining done exactly how you want it. I've built all my own engines for years, including the one currently in the race car. Spending 20K on an engine or even more is sometimes what it takes to get things just right.

But what I balk at is the average person who just gets ripped by a shop who really only provide a basic rebuild, change a few bearings and gaskets, use the cheapest parts and most basic machining and still charge these types of prices. I think that type of rebuild is far more common and people don't realise they could be getting a lot more for their money, or doing the same average quality job themselves for half the price or less.

Engine rebuild - flash - 03-13-2013

yeah - that kind of rebuild should be about $10k.

figure 10hrs out and 10 back in, with another 5 to take it apart, 10 of cleaning and prepping, and 20 or so assembling and setting up. that's 45 hours at average of $100/hr. $4500

balancing and honing and such $500

valve job $500

rings, bearings, gaskets, yada yada $1500

parts you really should change while it's out (motor mounts, hoses, etc) $1000

i'm at $8k and we haven't dealt with any stuff that needs to be replaced because the owner waited so bloody long, so you can see how it can easily become $10k.

but i agree that it should be a pretty special build, or something really wrong with the engine to get much beyond that.

Engine rebuild - WJH - 03-13-2013

If it cost over $10K to rebuild these engines yourself, mine will be for sale in a few years. I love the car, but on my income I couldn't justify that cost unless these cars become way more valuable. I have a nice shop and have always done all my own car work, otherwise I couldn't afford to have this car. I'll enjoy it while I can.

Engine rebuild - Lear35A - 03-13-2013

In my opinion doing a rebuild on one's own is a combination of personality, opportunity and financial circumstances.

Some people like mechanical stuff (I fit here), yet some don't. (Some people garden; I don't.) This is the "different strokes for different folks" area. Thank God for these differences, but some just don't have the aptitude or interest in doing something like this.

Some people have the space and tools to be pulling motors and such. (Luckily I do.) But some may live in apartments or have other circumstances that would totally preclude taking a car apart. We all agree that doing a rebuild takes time, and a car down for an extended period is a no-go for many. Also for those that use these cars as daily drivers the uncertainty of the time required to do-it-yourself is an additional issue.

Taking an engine to a rebuilder can be expensive, but as Flash pointed out some can be making $400/hr while paying someone else $150/hr to do the engine work. That would make financial sense. I would say though that if you have the personality and the opportunity, there is a (perverse) sense of enjoyment in doing this work.

One good thing is the great resource this (and other) board is to help those that want to give it a try. I had no intention of rebuilding an engine, but with the help of others I pulled it off several times. And I'm glad to help others as payback. All you have to do is ask.
