I was reading the Excellence article about the budget 912 racer and the owner claims 140hp out of the engine. They didn't talk the about the price of getting that kind of output from 2 liters except that there was alot of head work and special pistons were used. ($$$$) Anybody have an idea of what it costs to get a reliable race motor with that kind of power? And, if you can do it, is it only a track motor or could you autocross it also?

All it takes is time, money, blood, sweat, and tears. Mostly tears at looking at how much money you spent...
All you have to do to get power out of a motor is spin it fast enough. The real $$$ comes in making sure that it can use that RPM effectively (that's money spent on flowing the heads, etc.) and on making sure it can stay together for a little while at your target RPM.
A "race motor" can run on race gas. I believe 105 octane is available, and I know that 100 is. So the compression will go up--and up--and up! Couple that with a very lumpy cam and heads that flow very well (and more compression because the cam "bleeds it off"), and it's not hard to get to 140 HP. The EP guys used to get 140-160 HP routinely out of 1.8 liters, so getting it from 2.0 liters should be a little easier!
It will cost cubic dollars, though. And don't expect to put too many hours on it before you need to "freshen" it up.
SWAG? $10K development, $5K+ build, a couple grand for every "freshening".

You forgot to include the price tag and build time.
Oooh oooh...Let me guess, $10k and 9 months...
That was the question in the first post, right?

I see you've been hanging out with Grant
actually, his question was a little vague, is he talking a true 912 motor or is he asking about building a Type IV?
Does he need a "race" motor or is he just using the term loosly?

shit, ill even go one step further. i have a 1969 2.0 T motor core (of same shape you start with a type 4 core) I wil DONATE to you if you can rebuild to 140 HP cheaper than a raby kit.

Aaron,
I think if you took that core all the way to stuttgart and asked Porsche to rebuild it, they'd smelt it down and build you up a new one with the metal rather than refurb it

No time line or price was mentioned by the original poster.

Look at the question in the original post.
Very specific.
"Anybody have an idea of what it costs to get a reliable race motor with that kind of power? "
that was all...

yea sorta specific but could be asking the wrong question..."why" a "race" motor when one can get that power from a street engine??
"race" engine is too broad of a term and is often misused

140hp is a well tuned street 2.0. It could be built for less than 5K if you watch where you spend your money.

Fresh meat always tastes best, its better when the blood is still warm! I
On a more serious note, a 2056 can easily get you 140 ponies with the right cam and heads, especially if running on race gas..
I honestly seldom ever look at the poster's info when making a post, it doesn't really matter because if its about HP on this forum it's going to turn into a pissing match....

Get a six, get a big 4
Either way you will spend money, those that just dropped huge coin on a six conversion to obtain 140 HP. should be proud of thier car.
those that entered the Massive Type IV club equally should be proud of thier car.
Both recipes require more money than I have. wanna go fast? buy some better tires and learn how to drive.

I'm with Joe on this one.
HP is the last thing you need to go fast. Better tires and suspension, and a lot of work on the nut behind the wheel. That's the way to get faster without breaking the bank.
