    Red face History of 3.4 Engine

    Trying to get a handle on the 3.4 motor used in the Cayman S (mine is a 2008). If this the same motor that was in the early 996 series 911? If not what are the differences? If it is the same did the 996 have the oiling issues that members in this forum have experienced? If not why not? Just trying to get a handle on the history of the motor. Found a 2008 911S with 3400 miles and I am considering trading for it. The dealer price is $76,900. Is this a good price. Not giving up on the Cayman, but always wanted a 911 and this one has the new motor with direct injection. Any and all information will be appreciated.

    If it has DFI then it's a newer 9A1 engine with no IMSicon or the accompanying failure problems. That's a fairly good price on the low mileage 2008 911S. I'm assuming 6 speed? The 9A1 engines didn't appear on the Cayman until 2009. The only lubrication issues with the new 9A1 engine are due to high sustained turning forces during racing conditions.

    A 2008 911S wouldn't have the DFI engine. Only 2009+ cars have DFI.

    Not the same engines the 911 had the M96, no variocam-plus and it too had oiling issues but they were less prevalent because the engine is in the rear and turned around so the scavenging pump on the heads worked where oil would pool. When they turned the motor around to go into the Cayman they forgot that the pooling would happen in the other head where there was no scavenging pump so the oil starvation issues became more noticeable. A 2008 911 is going to have either a 3.6 or 3.8 engine depending upon if it is an S or not, you said S so that means it is the 3.8L engine. DFI was introduced earlier in the 911 than in the Cayman, but I've also heard some of the early DFI 911's have had problem with fuel pumps, etc. since it was a new system. Given that the car was probably $90-$95K new, $75k seems HIGH to me because in the past year you could get discounts on NEW 911's of $10-$12k, meaning a brand new 2010 model would not be much higher than a 2 year old used one that you are referring to. If it were me I wouldn't trade as you've described, but of course that's up to you.

    Re: History of 3.4 Engine

    Are we certain a 2008 997 (built in 2007 or very early 08) has DFI ? It does not seem that long ago to me that DFI & the 91A unit was introduced...

    I'm pretty sure the DFI came with the 2009+ models, along with a bump in horsepower. The 3.6L went from 325 to 345 and the 3.8L went from 355 to 385 hp.

    Re: History of 3.4 Engine

    Want to thank everyone for the feedback. It seems there is some differences of opinion as to whether the 2008 911 had DFI. All the checking that I have been able to do indicates it came with the DFI. I'll have to do more checking on the pricing of the 911. The retail on the 911 was $98620.00.

    The disappointment with my CS is that the dealer has not been able to realign my suspension to meet my autocross requirements. I will be going to another alignment shop to see if they come up with the same results. If so I will then write Porsche about my dissatisfaction with the car. Wrote a previous thread on this. It seems the dealer can't get the rear alignment set to the factory specs. I realize the front negative camber has it's limitations.

    I agree with K-Man S on the high price. Check the latest issue of Excellence for the used 911 buyer's guide. It shows low and high retail pricing for all recent 911s.

    '09's were the first year with the DFI. I think...
    '11 Carrera 4S. Black with black standard interior, adaptive sport seats, infotainment package, sports exhaust, PDK, auto dimming interior, heated seats, 19 turbo II wheels, wheel center with color crest, sports chrono package plus, extended nav 3.0, bose, xm, 3 spoke sport steering wheel with shift paddles, aerokit, illuminated door sills, tinted windows.

    Re: History of 3.4 Engine

    One year ago I looked at a very slightly used 2008 911S with MRSP of 98K. The BMW dealer had taken it in on a trade; asking price then was high 60s. I knew the car had no adverse history and was surprised at the amount of depreciation on a then 15 month old car. I thought it was a good price, but wouldn't consider black and really had eyes on 4-door M3.

    That same dealer is now asking 48K for modestly equipped 2008 CS.
    The 48K is high, as is the money being asked for the 2008 911 you are looking at, IMO.

    Re: History of 3.4 Engine

    Just read a good article on the CS 3.4 L motor in "GT Porsche" July 10 issue. I will see if it is available on the internet. Good information. This is an English (British) publication.
