Ferrari Mailing List: Re: Converting a US 308 motor to a Euro 308 motor

[Martin Stark (mstark]

It's not really the bit more power it's the way the engine accelerates coming off idle with the better timing and no air pump.

There's a simple timing change (to Euro spec) in the TR that grabs back about 5 or so of the lost HP.  Though slight it is seat-of-your-pants noticeable.  No problem with 93 pump gas. Driving my TR today in Boston traffic - very well behaved.

You serious about the TR power difference?

Wow, I never heard that. Pretty crazy.

I think with 308s, it's possible that there's a healthy gap as well probably because of the smog equipment and how it was dealt with. At least on the carbureted cars....the injected shouldn't be too far off. 

And agree about the displacement. Now that a lot of equity has been made owning a 3x8 car, makes a lot of sense turning one into a 3.4 or 3.5 liter beast.

10bhp is what Ferrari claimed was the difference was between the US and Euro spec TR.

Felt like 50bhp in reality...

If you are rebuilding already...why wouldn't you punch the displacement out a bit for more power??

Perhaps I am being crass, but the difference is only a claimed 10hp, which probably translates into 3-5hp.  Not noticeable.  Go for the best engine you can easily find.

Just thinking out loud.

 

My car has a Euro 308 motor and I'm glad to have that potential extra power. I need to replace rings in the motor, and as Clyde astutely pointed out, the labor of that type of job is likely to FAR outweigh the cost of getting a replacement long block and dropping it in.

 

It is easier to find a US 308 motor, so if I were to purchase a US motor, what would I have to do to make it a Euro motor? Obviously I have my euro cams already and could drop them in if that's about all it took. How much more involved is this job f converting a US spec motor to Euro spec?
