so i have two setups in mind and i want to pull the trigger on one. FI is new to me so im looking to the experts and expirenced here for advice. currently my car is 01 ss ls1 with lid, 85mm tb, bbk ssi intake, bbk lt's with a cutout and corsa catback. full suspension.

so heres the two setups first is a sts rear mount turbo, would be getting the basic kit and the upgrade to the intercooler kit, i know about the oil problem and would be getting the mocal pump and doing the restrictor. although i would hate to take off the bbk lt's i just put on a mere week ago (stock manifolds wrapped to contain heat is higly recommended and makes turbo spool faster). with this setup i would also get better springs, rods and rockers and a high flow oil pump.

setup two
recently found a magnuson mp112 supercharger (roots style) kit that fits under ss hood with minimal mod to hood. with this i would be getting new rods and springs and maybe new rockers as well. id get to keep my bbk long tubes but id have to get rid of my bbk ssi intake, which was put on at time of headers, a week ago. w/e lose some win some.

im leaning more in the direction of the supercharger ive heard alot of things about sts failing and breaking and frankly the supercharger install just seems easier. stock bottem end for both setups and stock heads/cam. will do heads cam later. thanks for reading a long post and i really need advice. thanks

From what i know and its not much, turbos are more efficient than superchargers, and ive only ever owned a cetri supercharger but i know roots style is better IMO due to alighnment issues and so forth.

It honestly all depends on the main purpose of your car. A car your going to drive alot id lean more toward the turbo for the fact of being efficient IMO
If tracked alot id go roots style blower due to (depending on size of turbo) no boost lag and i think superchargers are more maintanable than turbos are.

Im sure someone who has a turbo ls1 will chime in and same for a s/c ls1 member, theyd be able to tell you more about the realistic pros and cons more than i would

Are you sure that the supercharger will fit under the cowl without modification. What would be the cost to HP in just building a HC 383 stroker.

yes the kit fits under hood. A 1/4" drop kit of the K-member and cowl notch kit are included to accomodate the blower. from the outside you cannot tell that the hood was messed with

you can never go wrong with a s/c. plus that way you can keep your exhaust
