First thing... you cant just bolt up turbos onto a SL engine... the compression its different than the vr4... if you put turbos on a stock SL engine you will ambey make it a mile down the road and it will throw a rod or detinate and blow a hole in your piston. Used tubors are really cheap. you can go to DSMtrader.com and find some 13bs or 14b for like a $100 bucks a peice... but seince your a SL this is what will be involved to comvert it to turbo.
First off your compression needs to be lowered... that is something you cant really do your self... so you would have to have it built to 8:1 compression. then once you have that done you will have to then but new exauhst manifolds that will allow the turbos to bolt up. new downpipe, intercooler/s, and new intake lines, and then once you have that done you will have to get it tuned with a piggy back MAPing system (MAP-ECU) because it will have to be running just right not to destory the engine. all in all i mean thats about a $7000 - $10,000 conversion (the right way) and if you where geting new turbos then it would be alot more ALOT. and thats just to get it running... to get it running like a vr4 you would have to get alot of stuff... the SL throttle body is much smaller than a vr4s and the intakes is smaller too... i mean once you get into it... it is a very pricey thing to do... i can go on forever. you would be better off going and buying a vr4 or a JDM vr4 engine and drop it in.
