Which would you choose?, Subie w/325 hp or 2.8 massive IV with 225 hp Options

[hot_shoe914]

Okay I have come to a point where I am in a delima. I have a '73 2.0 car with the appearance group package that has had all 911 suspension upgrades and I will also be adding GT flares. I was originally going to put a 2.8 IV in it with about 225 horses but now am considering a subie engine putting out about 325 horses or more. I have always been a purist but there is something to be said for smoking the competion through the curves and also being able to dust the muscle cars down the highways. I can get into the 2.8 for around 7000.00 for motor and tranny minus installation. I can get into the subie for about 4800.00 minus installation.

What are the thoughts and opinions out there along with the pros and cons for each. All input would be greatly appreciated.

I think the real question comes when you ask, when is it still a type IV, and when is it something else?

Thats why we have been referring to our engines for years as "MassIVe 4s"

How much less originality is present with a chopped up and modified to hell engine, versus just replacing it with something else similar? Where do you draw the line?

A Subaru isn't similar. A Porsche 6 cylinder only shares it's cooling medium and the fact that it is horizontally opposed with the "MassIVe 4" or the Type 4.

Do I still have a type IV when I've cut large amounts out of the case to fit my huge cylinders?

Thats why we don't do that. Most all our engines make their power with a 96mm bore that slides right into the stock, non machined case.

How about if I weld up the heads to move the exhaust ports

We don't do that either, in most instances..

What if I replace the heads entirely with aftermarket ones?

Don't do that either..

If you follow this road to it's logical conclusion, you end up at http://www.pauter.com, making over 900 horsepower for drag racing 4-cylinder cars.

You said it "Drag Racing". How many teeners drag race?

Their shit is expensive, but it's only money right? You'll always make more.

Thats right.. And thats why my Wife's twin plug 2.9 Liter street car makes more power from less displacement than Don Pauter's Ghia street car that uses one of his "Big Block" engines of greater displacement (3140cc Vs 2866cc). Her engine also gets better MPG (even using 52mm Weber carbs Vs EFI on the Pauter engine) and utilizes STOCK TIV head castings with the only welding being done for the second plug modification. The Pauter engine uses an aftermarket head with much bigger valves and ports.

The stock TIV case is a great foundation. We'll be making over 1,000 HP from a Porkies head equipped, boosted twin plug roller cam engine by years end- if all goes as expected.
