Value of a 7R case? Options

[Wegeng_Haus]

I'm looking for opinions on the value of a 7R 911 engine case, fully machined and Case Savers installed by Ollie's? Thanks. (IMG:style_emoticons/default/icon_bump.gif) (IMG:style_emoticons/default/confused24.gif)

2.4 or 2.7?

2.4 or 2.7?

Starting point, perhaps.

If you have receipts for machine work, and detailing what was done; probably $8-1200 depending. This is hard to research fair market value. You might call Ollie's and see if they can help put a value. Pelican or Early S page is probably going to be a better site for it selling it though.

Is this Dave?

I know that I paid about $2000 to Ollies to have my 7r cleaned, fully machined, case savers and bypass modification. That was just for the work so $1200 for your case seems low to me.

Funny thing is less than 8 years ago I could't give away a known running 2.7 disassembled core with a std/std magnafluxed crank for $1000 (asking was $1200).
I just said fuch it and packed it away, it's my backup engine or hopefully I'll find a home for it one day. I pick away at small jobs on it from time to time, heads are half done and I'm collecting small parts.

With all the other cores becoming spendy the 2.7 is finally getting some love.

[BK911]

A 2.4 7R case is worth some coin.
At least $2k as a core.
2.7 not so much.

why do you say that?

why is one 7R worse a than another?

iirc - a late 7R with the upgraded oil passages or mod is about the best of 'em

Most consider the 2.4 to be potentially less stressed than a 2.7, both physically and heat stressed.

I think that if it is a good 7R (with all the studs) it is worth at least $1000 plus the worth of Ollie’s machine work. These things work fine for a street motor build IMHO.

This also assumes that you have the rest of everything you need to put the whole thing together. Trying to piecemeal one of these together gets very pricy. Better to start with a good long block core. There was a recent thread on this in the classifieds

[jasons]

The 2.4 is just way more rare. I think they were only around for half of 73 for the short run of CIS 2.4's. Because of the bore size, they are the case of choice for people looking to build hot rod 2.4ish motors. The rarity of the bore size drives the price, not better or worse.

I sold a 2.4 7R long block core to a member here for like $1k a bunch of years ago. That was before the Porsche price bubble. Ironically, the engine code on that one was MFI so it must have been right at the cut in of MFI to CIS.

also the 2.4 case has small spigots and can be down sized into 2.0
The 7r case 2.1 race motors are stronger than a 3r/5r race motor

Multiple people are getting into the replacement case market. Billet aluminum cases. Heavier than Mag but much stronger and ready to build right out of the box. Won't be cheap but Mag has a short working life that gets shorter when heated. The aluminum cases should last our lifetime and beyond.

I’d check with the folks on the Pelican Parts 911 Forum for opinions as well.

There's a guy touting his replacement 6 cylinder cases but as yet not one has been produced for the market.

Billet VW cases are another matter. Were I in the market to do a hot rod I'd consider the 914 4R"000 Build" in the latest 000 magazine. Shooting for 1700 pounds.

From the article the author makes a valid point that the six is around 110 pounds heavier than the 4 and it only gets heavier with displacement.
I'm not a POLO engine buyer because the output doesn't justify the price. A FAT engine suites me. I know they work from my friends experience with his 2.8 which was the scourge of the autocross scene and FTD at the PCA Parade in 2008. They've only gotten better.

That's more of a 4 vs 6 thing. 99.99% of 911 owners will never put a 4 in their car and the PO is asking about the value of a 6 case. I think the more desirable cases will become less desirable once the replacement 6 cylinder case market opens up. Every other part is now available aftermarket so it was just a matter of time before cases were made. I know we are talking about an upscale market but that is sort of the definition of Porsche.

The 962 at our shop uses a 3.0 turbo case as a base for it's 780hp. The new billet cases should be even stronger.

I paid $1,500 for a 2.4 7R case with no machine work done to it 2 years ago and that was a deal.

[brant]

the 2.7 case is still not a high dollar or high value case
reworked helps a lot
and most people will no bother to build a 2.7 when they can buy an aluminum 3.0 motor for less than the rebuild.

some folks that are racing a specific class, or going for originality will use the 2.7 case. but its not the most desirable case unfortunately.

[seanery]

Tell me more, where I can I research these?

This post on pelican list a couple of the guys doing it.

The downside is that you could get the case for free and you are still looking at an expensive engine to build. Crank, rods, heads, pistons & cylinders, dual dizzy, fan & shroud, bearings, oil pump, ect. will still cost tens of thousands if you buy new. Even if you buy used parts it will be $10-15K aditional. We did a 3.8 for a customer and it was $80K in parts. I learned from my cycling days its always more expensive to build piece by piece than to by a product and modify. If $15-20K for a 3.6 is beyond your budget, building on a new case makes it look cheap.

But I love that these guys are bringing more product to the market. There will be plenty of people who can afford it.
