JR80911 Posted 16March, 2014 Report Share Posted 16March, 2014 Hi guys - hoping to take advantage of the experience of everyone. I've had my sc for a year or so now and I've had no issues. But it has done 260k and I'm not sure whether the engine has every been apart. How much do you think I should budget for a rebuild? thoughts would be appreciated. I'm thinking 10k to 15k?

ByronBayChris Posted 16March, 2014 Report Share Posted 16March, 2014 Depends on what gets done Split the case and.you are up to $23 Link to comment Share on other sites More sharing options...
clutch-monkey Posted 16March, 2014 Report Share Posted 16March, 2014 how much can you do yourself? Link to comment Share on other sites More sharing options...
Russ Posted 16March, 2014 Report Share Posted 16March, 2014 does it need to come apart? keep oil changes up and general maintenance and I think you'll be fine for quite a while as everyone has said depends how much you can do yourself. Might be worth getting "how to rebuild and modify Porsche 911 engines" http://www.amazon.com/Rebuild-Modify-Porsche-Engines-1965-1989/dp/0760310874 Link to comment Share on other sites More sharing options...
clutch-monkey Posted 16March, 2014 Report Share Posted 16March, 2014 might be worth just doing a top end refresh perhaps. but then, the engine's pretty much apart anyway.. Link to comment Share on other sites More sharing options...
Pauly Posted 16March, 2014 Report Share Posted 16March, 2014 with 10-15k you could wake it up a bit. But it all depends on how much you do it yourself. If the bores are good, you probably could do it all your self. You might need to get someone to check roundness of your bores and the wear on your crank though. Other then that, everything is pretty much tightening up bolts so to say. Good opportunity to get some light weight forged piston and rods. custom grind camshaft and a bit of head work. I like to bag small items with their nuts/bolts ect and lable them. For example i had bags with: injectors+fuel rail parts head studs and nuts pulleys and nuts rod nuts griddle nuts oil pan bolts You get the picture Took a lot of photos too!

Ben C3.o Posted 16March, 2014 Report Share Posted 16March, 2014 Hi JR, Have you had a compression test and leak-down test carried out on your car? I was in you position up until last week. My car is pushing 267k and I had been told by Zag Automotive, who resprayed my car back in 2000, they recalled she had a full engine rebuild at the same time but I have no documentation to prove. Anywho, last week I dropped her off at Auto Werks for a major service and thorough going over. Having had the same thoughts as you, before they did anything I got a compression test and leak-down test done. The results were pleasing and didn't indicate the need for any major work at this stage. Great news, and gives me a nice bench mark to keep an eye on my cars engine health each service. Simon also found she has a 3.2 oil pump which tells him she has had a full rebuild some time in the past, now I have some form of proof of what Zag remembered. HTH Cheers Link to comment Share on other sites More sharing options...
JR80911 Posted 16March, 2014 Author Report Share Posted 16March, 2014 Well to be honest id love to do all of it but I'm an absolute amateur so not really that confident. Most I've done is change the oil! But it sounds like 15 k will at least do the top end. I might do a compression test and leak down as suggested at next service. I bought it from Weltmeister and they did show me results but that was a year ago. What is a "good" result when doing the tests? Any recommendations on service? I used to take it to Pacecars (don roe) but have moved to ormond. Are there any options others would recommend? Link to comment Share on other sites More sharing options...
Pauly Posted 16March, 2014 Report Share Posted 16March, 2014 We all start with an oil change. I'm pretty sure that's how it is. You think well that was easy. Then you replace a sparkplug. hey that was easy too!. You need to remove your intake manifold and realise that was quite easy also. And that's where it starts.

clutch-monkey Posted 17March, 2014 Report Share Posted 17March, 2014 and then you realise taking it apart is the easy bit.. and have a pile of porsche that has to be re-assembled Link to comment Share on other sites More sharing options...
Simonk Posted 17March, 2014 Report Share Posted 17March, 2014 My leak down results when I bought my car were less than 2% on all cylinders which is supposed to be good. I spoke to a couple workshops about rebuild costs in the future and both said up to $15k for a top end rebuild. I use Motion Automotive and a couple other guys here also use him. Factory trained back in the 70s so he has plenty of experience with the old models. He's in South Melbourne and was thinking about moving to Moorabbin.

T-Man Posted 17March, 2014 Report Share Posted 17March, 2014 I'm trying to understand what has prompted the question. Is the motor burning oil, and if so how much? Does the car feel down on power? Is it blowing smoke? Quote from a Rennlist thread on leak down numbers from what many consider to be a leader in his field. 2%-5% is very good 6%-10% is OK 10%-15% requires some further investigation for the source of the leaks 15% or over requires close attention to find the source of the leaks and fix them. __________________ Steve Weiner Rennsport Systems Link to comment Share on other sites More sharing options...
9fan Posted 17March, 2014 Report Share Posted 17March, 2014 If it is only a year ago ask Weltmeister for the records ! Link to comment Share on other sites More sharing options...
CarreraG50 Posted 21March, 2014 Report Share Posted 21March, 2014 You could try one of these, not sure how you would go for warranty, I would guess freight would be around a $1000 (I really have no idea) but for $10500USD (plus freight) your getting a rebuilt engine. OK link not working google-: vertexauto.com engines they also rebuild gearboxes Link to comment Share on other sites More sharing options...
JR80911 Posted 22March, 2014 Author Report Share Posted 22March, 2014 @ t-man: nothing particular. Engine is goog great. Probably needs a service soon but no leaks no smoke. Just making sure I have an idea if cost if it goes. @ 9 fan. Yes true. Might give that a crack. @ Carrerag50. Yes. Things seem to be much cheaper. Always an option. Handy info though. Thank you.

Tit Posted 22March, 2014 Report Share Posted 22March, 2014 I used Michael at Autoart in preston for my top end rebuild. He was very good and his rates were very reasonable. Link to comment Share on other sites More sharing options...
oldslappy Posted 24June, 2014 Report Share Posted 24June, 2014 I Purchased Wayne Dempsey's book (which I highly recommend) "How to modify & rebuild Porsche 911 engines." Then whipped the engine out & dismantled until I was left with 2 case halves. I had a machine shop fit new valves & check all measurement were within tolerance. Then re-assembled it. The most money was spent on shipping parts!! I think I spend around $5000 in total. BUT If I were to do it again I would take it somewhere, I may have saved a bit of $$$ but I'm sure the whole ordeal of the rebuild took years off my life & left me with significant hair loss!!!

OK link not working google-: vertexauto.com engines they also rebuild gearboxes is that you send your motor over and they rebuild it and send it back? at $14k for a full rebuild here there's some savings there if you're able to get good shipping rates, may be close though. similar to slappy's post the last refresh (top and bottom) i had a hand in was about 8k in parts and labour, maybe a smidge more. pistons were still good etc, nothing had lunched itself, or it would have been a different story..

CarreraG50 Posted 24June, 2014 Report Share Posted 24June, 2014 is that you send your motor over and they rebuild it and send it back? at $14k for a full rebuild here there's some savings there if you're able to get good shipping rates, may be close though. similar to slappy's post the last refresh (top and bottom) i had a hand in was about 8k in parts and labour, maybe a smidge more. pistons were still good etc, nothing had lunched itself, or it would have been a different story.. No thats for a complete rebuilt motor, if you send an exchange "core" its $8500 for the rebuilt motor, not worth it, just buy the motor for 10.5.

Is the savings you get from buying a complete rebuild engine going to bite you in the ass when it comes time to sell and your car is no longer matching numbers?

CarreraG50 Posted 24June, 2014 Report Share Posted 24June, 2014 Well you will still have the original motor, even though it needs a rebuild. The purchaser could rebuild it while still driving the car. Selling point car comes with two complete motors (Small print 1 is shagged) Link to comment Share on other sites More sharing options...
Russ Posted 25June, 2014 Report Share Posted 25June, 2014 I don't know if it's been established if the engine even needs a rebuild there's kits online for seals/bearings which is an 'engine refresh' kit for $979USD. Pistons are about $2500 and then whatever head work you need. Then if you need barrels and other misc stuff that'll be broken/worn out/improved I'd probably budget another $2000 for that I think I could do a rebuild myself for $5000-$7000, but i'd be attracted by a drive in/drive out option with warranty on my existing engine Link to comment Share on other sites More sharing options...
