Ramana SP Rally Car reprep 2012

Conducting a full teardown of the Super Production STI which captured many Rally-America wins in both 2011 and 2012. Few people know that this car used to be Ken Block's "Trax" car and was outfitted with tank tracks in a prior life. Scot is overseeing rebuild duties.

Evolution VIII Hillclimber- Kih

Kihurani brought us his Evo VIII for a Rally America Super Production class build. A year later the project took a new direction as he chose to become more competitive in the PA Hillclimb Championship. In 2010 the car was stripped and a full cage was fabricated. In SP Class, only the engine management and exhaust can be modified. A 34mm restrictor has to be installed which requires machining of the compressor housing. A Vipec V44 ECU was installed and Bill fabricated a Group A type exhaust with double slip fit connections, a 100 cell catylist and a small resonator. This year we're starting a new stage of development, no longer restricted by Rally America Production class rules we're upgrading the turbocharger to a Garrett GT3076/ Tial Housing, tubular manifold, custom downpipe, AMS moustache bar eliminator, removing EVAP system, Ralliart bushing kit installation, Bosch ID 1000cc injectors and remapping. We'll be adding all power-supporting parts to the build along with an intercooler and pipe kit from AMS.

K24 Civic EG

Robert brought us his pristine Civic hatchback to make it go around Lime Rock Park faster. We took some steps in the right direction. On the first visit to the shop the car had an engine prepared by another company. We have since removed that D Series motor and we're installing a K 24 with no turbo this time. The k series motor will make more power with no turbo than the D series did with a GT30. The K series is a collaboration between the best Honda builders in the country. We are working with Benson's, Laskey, Endyn and Hi-Tech. Benson's did the sleeving. Laskey built the short block. Endyn is completing the cylidner head with a custom set of cams and a matched header by Hi-Tech. It does not get ANY better than this for Honda. DSG is completing final long block assembly in house and conducting tuning on it's dyno under Matt Koestner.

4G63 Powered BMW E30

Adding this to the album for nostalgia. This car was built in my driveway in Newton MA. It spawned a new confidence in what could be achieved on a low budget and taught us a lot about cars, in more ways than one. The bimmubishi was built with basic tools and a 135 amp mig welder.. nothing special. It was a decent early attempt that sub came to constant gearbox problems (no one made transmission adapters back when I built this car) I am of the belief that it's the very first 4g63 powered BMW in the world.

It held it's own but proved far too unreliable for a race car of any stature. It was retired and the shell was reused for phase II, the SR20det motor which worked much better but was only a small step up in the large scheme of things.
