ive been hearing a lot about the hahn turbo it and the price of that is 4k. plus you need to up grade your pistons and maybe rods. the easier and cheaper way is to get a newer saab manifold.(thay invented the ecotec). and you could build a kit for less than half the price. im goig to be doing this over the winter. next year twin boost.

 

Cool. Good luck!

 

thanks.. its actually going to be easy. the hardest part is to run the oil lines and upgrading the after cooler. . the spercharger heats up the air so much that it is hard to find a better way to cool the air
