SIX VS. FOUR, when does the six win? Options

[Trekkor]

Some say go six, some say stay four or go BIG four.

At what point does the SIX take over?

I run a 90 hp four and have been told that my 'lil SIX will make me slower with my 130+ hp. PO says 245hp. Won't truly know 'til dyno day. Which may sway me.

What kind of weight increase are we talking about?

Will I enjoy the car more on the street with the SIX?
Because let's face it I run 1-2 a/x a month compared to my 200 miles street driving.

a/x season is coming to an end soon. I'll finish with the four.
My project will be during winter. If the SIX is bogus I'll put the four back in. (IMG:style_emoticons/default/confused24.gif) Only my time with my car hobby has been spent. ( A few bucks, too. ) (IMG:style_emoticons/default/idea.gif)

When does HP win out?

Up to 2,7 ltr both engines can be made equally strong. The six will however always be heavier and therefore needs some extra hp to be equally quick.

The difference will eventually be reliability. The six will always have more reserve with that aspect. The four needs way more tricks to be reliable at the same hp rating. A big four will be high strung, whereas a six is just mildly tuned with about the same power.

Strangly (or logically) enough, thats where budget comes in: With Nikasils (standard on most sixes), dry sump (standard on sixes), mods to make the outdated underhead valvetrain lighter (well, you know what Porsche did for that one), a big 4 can be made very reliable and then probably costs about the same if you let others do the engine building for you.

Although this reaction may lead you to beilieve otherwise, personally I like the type 4 better. A lighter car (especially a type 4 with Nikasils) is always more fun to drive fast (IMG:style_emoticons/default/smile.gif) and as stated before, a type 4 can be build more easily by oneself than the six IMHO...

Good luck,
Walter
