The DME was replaced, of course, and it cost big bucks, but what a cool way to embarrass any Corvette in town.

More $$ because regardless if you are e-gas already or not your DME version can't run the newer systems that are in the 3.8.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi, My buddy hit somehting last night asn Porsche is telling him that the engine is trash and will need to be replaced. This is a 2002 Targa, Is there a larger engine he can upgrade to while he is at it ? I was thinking you can put a 3.8 in the car, but I could be wrong I really live over in the aircooled world , so Let me know Also what was the cost of the two the replacement 3.6 and the 3.8 Thanks

POST 2Original post

Not easy to do. One would need a fabricator to do the work and you would have to replace most of the engine electronics. $$$$. Not really recommended. 3.4 --> 3.6 is much easier to do.

POST 3Original post

Quotes source post: 5323692

really? I thought it was the other way around. The electricals (especially e-gas) are more similar in the 3.6 and 3.8, I thought. My indy has two 3.8 engines he bought in case someone wants to upgrade from the 3.6.

POST 4Original post

deoxford, The shop that did my 3.4 to 3.6 swap is in Atlanta. They can do the 3.8 as well. More $$ because regardless if you are e-gas already or not your DME version can't run the newer systems that are in the 3.8. 3.4 to 3.6 is pretty straightforward. 3.4 to 3.8 involves a lot more electronic systems including swapping to the newer instrument cluster and hvac, etc. PM if you want their contact info. -Paul

POST 6Original post

there are a handful of companies who will sell you a remanufactured 3.6 bored over to 3.8 or 4.0L english one was named...

POST 8 / ORIGINAL POSTEROriginal post

Does anyone have the companys , He decided to go ahead to replace it with the 3.8 ... you know while your in there..

POST 9Original post

Try http://www.rufautocentre.com/ I am sure they can do it.

POST 10Original post

u are talking big bucks here. ruf is great but terribly expensive and autofarm is in the uk...the exchange rate will kill u plus the cost of shipping it here. alot of money for +/- 50hp increase, not worth it imo.

POST 11Original post

3.8 into a 2002-on car is a simple task. Todd

POST 12Original post

Todd is correct, I have one in my 02 c4s, which I was able to do myself minus the tuning.

POST 13Original post

$$$$KA-CHING$$$$ That's all I have to say. C.

POST 14 / ORIGINAL POSTEROriginal post

Guys, Just a update, I have discoverd that the 3.8 is simple for this car. And I have found a shop here in Atlanta that does it. Matter of fact it is my shap and they have a Cayman in there right now with the 3.8 I am waiting to find out the cost. I am sure it will be cheaper or the same as what the Porsche dealer was saying for the 3.6 replacement ~12k

POST 15Original post

That's good news. I may do the same thing one day, but hopefully not soon.

POST 16Original post

what are you getting...a 3.6 bored to a 3.8 or an actual 3.8?

POST 17Original post

Quotes source posts: 5326079, 5326032

Did you guys drop in 997 3.8s or 3.6s bored over? I've heard there are DME issues with the 997 into MKII 996 but never looked into it beyond that (I'm not considering it but always curious) If you have any links to your respective installs I would love to se how you pulled it of cleanly.

POST 19 / ORIGINAL POSTEROriginal post

Ok, going to pull the trigger on this repair. Sunset is telling me that the 3.8 is really the X51 package is this correct. they have it price for $7820.00 -3.6 $2363.80 Core $8518.85 -X51 $2566.24 Core I just to make sure that the X51 is the correct engine And there are no issues with the swap Thanks for your input

POST 20Original post

Quotes source post: 5459139

An X51 kit is an upgrade that includes intake, exhaust, cams, lifters, and heads, as well as some other goodies. It does not include more displacement. X51's were available for 3.4's (not in the US) and 3.6's, and for 3.8's.

POST 21Original post

Derek, Just make sure to tell Sunset what Car model you want the engine from. The US choices are, 996 3.4 996 3.6 996 3.6 x51 997 3.6 997 3.8 997 3.8 X51 Just to confuse things there is also a Cayman 3.4 which is not the same as the 996 3.4 The other thing they likely didn't mention is that the core price you list is something that you pay additional if you don't have an engine just like the one you are buying to return to them. So if you want a 3.8 X51 you need a broken 3.8 X51 to turn in or pay the Core fee. Good luck!

POST 22Original post

Just re-read your original post.... since your buddy "hit" something I guess that he has a hole in the engine. That by Porsche's definition is not an acceptable core. The golden rule told to me was if there is a hole in the engine block that came from the inside out then it can be a core.. The other way around... no core.

POST 23Original post

wouldn't a 3.8 x51 in a 996 widebody be sweeet.....

POST 24Original post

FVD sells a crate 3.8 engine...it's has a 2 year warranty.....up to 381 hp.....

POST 25Original post

Quotes source post: 5459525

For the low low price of $26K installed

POST 26Original post

FVD in Pompano dropped a 3.8 into a Boxster. I was able to drive it - it is an amazing car. The DME was replaced, of course, and it cost big bucks, but what a cool way to embarrass any Corvette in town.

POST 27Original post

Quotes source post: 5459525

Was this ever done? If yes, was it worth and how much...? If I may ask.

POST 29Original post

Quotes source post: 5459664

A good supercharger kit would add more HP and cost a whole lot less

POST 30Original post

Quotes source post: 6328686

Sometimes that is not an option, for example because of inspection *****.

POST 31Original post

I have been researching twin turbo engine swap, looking for donor car

POST 34Original post

Quotes source post: 6329692

In some parts of the world aftermarket SC's are prohibited w/o exception in pollution controlled vehicles, and cars are inspected yearly. You really can't hide a SC. And if you import a 996 turbo, you'll pay about �34k in tax... In this case an engine swap is costworthy option.

POST 35Original post

Quotes source post: 6331246

Like in California - you can't smog a supercharged 911... thus you can't register it.
