About the mods and performance info I promised, here is a quick rundown of what has been done so far. Just remember this is a work in progress.
I have port matched the intake manifold to the heads, the exhaust manifolds to the heads and the plenum to the intake manifold. I opened up the intake and exhaust ports for better flow and matched and relieved the TB's. I have removed the air restrictor in the intake tube and installed a K&N filter. Removed the muffler under the seat so there is nothing but pipe between the cat and the resonator. With these mods I average around 23-25 mpg in the city and 32-33 mpg highway. The car is a whole lot quicker(0-60 in 7.5 secs) and the top end is incredible. I am working on a true dual exhaust, 2 1/2" pipe from the exhaust to the tailpipe. Not sure what type of muffler to use. I also have been working on a complete cold air intake from the TB's to the filter. I will keep you posted on how these mods come along. I run Bosch Platinum 2 plugs and have had no trouble at all.
