Rebuild a 2.7L or 3.0L six motor, which is cheaper? Options

[boxsterfan]

Which /6 motor is cheaper to rebuild? 2.7L or the 3.0L?

1. Assume core motor is in good condtion and no crazy findings when you tear it down.
2. Assume you are building the motor for longevity
3. You are putting this in a 914/6 conversion (was /4)

OK from Wayne's Book (pricing is 15 years old?), machine work you would do rebuilding a 2.7 but not on a 3.0.

$495 Line Bore
$350 Install Time Certs
$130 Oil system bypass mod
$29 Case saver inserts

=$1004, say *120% for today's prices = $1205

Looks like it is cheaper to rebuild a 2.7.

BTW His total was $3,300 for all the machine work (includes valvejob, rods and crank recon, etc...)

Total parts and tools was $2,872 which includes $1,400 for p&c's.

Grand total = $6200
This is a complete rebuild, only large purchase hard parts were the p&c's. EDIT-This Grand Total is older pricing from Wayne's book, please use your judgement for current pricing.

Quick note on the timecerts- They seem almost mandatory to me? The 2.7 I had you could only torq down about half of the headstuds... the other half wanted to pull out.

I'm going out on a limb here, but IMO there is vitually NO WAY you can do a "quality" rebuild of any 911 6 cylinder engine for $6200.
The prices in Wayne's book are very out of date.
Parts are much, much higher now.
Ever price a set of pistons & cylinders lately?
And easy $4-6k just there.
Depending on how
many parts are worn out, the picture just gets worse.
The big builders (i.e. Rothsport) will charge you $20k up to $30k to do a complete
engine rebuild.
There's a reason for that cost....and it's not all labor.
There is a lot of machining required, again quite expensive.

I think you're all kidding yourselves in this link.
Good condition, low mileage engines are rare as can be.
So now you're stuck with a rebuild on whatever condition engine you can fine.
To do a top end only is really a sketchy idea.
Add to this that most of us....even the mechanically adept....would be in over our heads with a 6 cylinder engine rebuild.
So much experience goes into the proper rebuild that the average guy is going to miss something during the process, and then you flushed a bunch of money down the drain.

Again all the above IMHO.
My takeaway.... rebuilding a 911 engine is not a trivial or inexpensive proposition, and not for the weak hearted.
But they are the best sounding automotive engine when done correctly bar none.

Very true, price of admission for a great builder is 20 / 30 k these days.
