help with supercharged 2000 ls1?
I purchased a 2000 Corvette convertible that was purportedly customized way back in 01-02, by a place called Karl's Kustoms in Des Moines Iowa, they basically converted it to a z06 underneath and installed lth, full corsa exhaust, high flow cats and everything, probably since they also own Karl's Chevrolet and they wanted it to be compliant if they sold it from there, it was also given a lingenfelter intercooled supercharger kit, Magnusson with Lingenfelter programmer to install their tune. It only has 44000 miles and the custom paint still looks like glass, they painted rally stripes out of red fire mist or something similar, against the raven black they look awesome, also the factory wheels appear to be powder coated black. The car is super nice, and i'm sure back in the day she was a veritable rocket ship. But fast forward 22 years later and i just want to be a little more competitive on the street. A little more oomph if you will. It is a 6 spd M6, and has 3.42 rear gears, so low end is incredible with the supercharger. I am at a crossroads, the notorious piston slap drives me absolutely crazy as i had a 67 Chevelle ss 396 that had a spun rod bearing that sounded similar. The ls1 in this car is strong and the knock goes away after about 30-60 seconds, never to be heard again, until the next time you climb in your super hot sexxxy corvette, in front of everyone and start it up and it sounds like it is about to creator. so i have 3 options that i have looked at very thoroughly. 1. get a 6.0 short block and put either tsp or trickflow heads and cam, the pros to this, no more p.s., a newer block, with newer rectangular port heads. the cons, trying to find a good 6.0 that has been rebuilt correctly, with enough compression as to not lose power over my ls1, and losing boost because of the larger cylinder bore. I have tried to find a larger front pulley for my Maggie and they don't seem to exist anywhere anymore. 2. rebuild with new pistons, that costs about as much as a built 6.0 shortblock, might as well stroke her while i'm at it, but then it has even more cubes than the 6.0 so back to way less boost as i understand, almost negating having a s/c. 3. i found a 2015 zl1 lsa complete from gas tank to radiator, including the tr6060 transmission which i can't use but can sell to recoup some money. But i just read that the LSA motor will not fit in the c5 due to the steering rack location.
Open to suggestions, or ideas but have a few questions as to why the lsa will not fit, but you can run an lsa s/c on your ls1. If the crank pulley is what is hitting the steering rack, because of the c5-s "corvette" feed, why couldn't i just transfer all of my old pulleys to the new block to get the same distance from the rack, and if i did that, how on earth would the "fixed in place" supercharger pulley line up with everything? and doesn't that mean that it wouldn't line up with an lsa supercharger on an ls1 if it sticks out so far as to change the lower crank pulley location that much? Just getting more confused, to the point i'm about ready to just put a cam and heads on an engine that sounds like it is chewing on marbles.
