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.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Can someone give me a list of differences in the X-51 engine vs the standard 3.4L 996 engine? What I know are as follows: Oil pan is different. Tuning is different Has a different oil pump to help with oil return and cornering issues and oil starvation Not sure if there is anything else? Thanks.

Here is the 3.6 info - which should be the same for the 3.4. PN: 000.044.100.15 new intake manifold new intake pipe supports new exhuast manifolds new cylinder heads new camshafts new inlet valve springs modified oil pan remapped engine management system 3rd radiator [edit: you will have to get the relevant parts from Europe as the 3.4 X51 wasn't offered in the US. Getting a 3.4 X51 kit to fit/work is not simple or cheap - but not impossible. I think the parts alone retail for around �7,000 ($10,000 USD), plus install and DME tuning/remapping. So maybe $15,000 USD all-in. At these prices, it makes a supercharger a viable alternative, especially when the X51 only gets you 25 HP...] -td

I was just curious. If i wanted to spend all that money I would just drop a turbo engine in. I was just wondering what they did to try and improve the power. Seems like a waste for that little gain. Thanks.

I am in the middle of assembly of a 3.6X-51 that we have taken to 3.8.. I added further head work, boosted the CR and enhanced the camshafts. I fully expect to produce 400-410HP on my engine dyno, maybe more.. We added all the updates, added Nikisil liners and designed a true 4 valve piston for the application. I would have been done with it if my Dad hadn't been in the Hospital all last week and the majority of this week.

Nice. That sounds really sweet. That is a lot more power. Now we're talking...
