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.

Cliffbraun,
If I were you I'd get a few more than 22 posts under my belt before making such a post. People might take you a little more seriously that have been on these boards since they were started... At this point you just seem like someone that hasn't done their homework on what we create and wants to throw more fuel on the fire with your opinion. You have zero first hand experience with my creations and your knowledge of who and what I am is probably limited to this post only.

As far as the "God" approach, well that type of attitude is what pisses off guys like Grant and thats why I like to employ it, when necessary. It really gets them going and it has obviously has worked with you as well. Meet me in person or talk to me on the phone and you'll never guess that the person you have read about here is actually me..

But with you being an ME in training, we aren't supposed to get along anyway. I look forward to future debates with you :-)

At any rate..

My post to Chris that was "pure shit" was meant to explain that an engine as large as a 2.8 is not necessary to make a broad power band with tons of useable power while tipping the scales at over 200HP from a 2316cc power plant, on pump gas.

One of the biggest issues we have to contend with from a consulting standpoint are guys that make the engines too large to be efficient. For years the idea was to build the engine as big as possible and it would make power, but thats just not the case. Those big engines are very difficult to equip with heads and exhaust that will be effective enough to create power or to put that power where it needs to be in the operating range. This is why 95% of my engine combinations utilize the 96mm bore as it provides the best mix of performance, reliability and cost when the sub system requirements are factored into the equation.

To me a "Big 4" is anything beyond a 2056, it doesn't have to use a huge 103 or 105mm bore to make big power.
Now as far as making big power on Alcohol:
We don't build drag race engines and no classes that the TIV competes in will allow the use of Alcohol. Most of the race engines we build are heavily impacted by rules that dictate displacement and the largest "race" engine we build is 2013cc for SCCA E Production. The range is pretty much 1500cc engines for Land Speed Racing (the current 1500cc record is held by RAT power) as well as 1832cc engine for SCCA F Production.

My focus always has and always will be on street engines that are capable of being dual purpose competition engines when the driver wants to attend an AX or a DE event. We turn down competition engines on a near daily basis because they are both not our specialty and they also take up a ton of our time that can be used to develop new technology for the MassIVe 4 street engine or to help educate the following on the proper methods of manipulating or tuning their own engine.

That said, the 2.8 engine thats been the topic of this thread is more than likely mis-configured and makes less power than a properly enhanced 2.3L engine. Thats the way the ball generally bounces.
