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. Donald (IMG:style_emoticons/default/confused24.gif) |

QUOTE What will you guys do for heads? Anything special to get 8000 RPM? Creating an 8,000 RPM 2 liter is a lot easier than an 8,00 RPM 2.4 liter. Our off the shelf LE 200 heads have enough flow for 8,000 RPM as they flow just a tad less than the E production heads on Kevin Groots engine that revs clear to 8,500 RPM and is stock stroke with a 95mm bore per the SCCA rule book. Thats a 207 HP engine from 2013cc. The rules have changed in ECTA this year, allowing up to 2015cc from the 2.0 class. This will allow me to build a budget 71X95 bored engine for Land Speed Racing where RPM is everything. I plan on running a very small chambered LE 200 twin plug head, 51mm carbs and see if we can top 155 MPH. That will take 9,000 RPM sustained... Big engines, especially those with stroke enhancements make their power lower and thats why the 2374 AX combo is so effective. With an 82mm stroke and a 96mm bore that combo really rips in AX. The stock stroke has lots of benefits, especially since the right rod and piston combo can create an engine more narrow and lighter than stock. There are many ways to design these engines..
