You need to get and engine management system so you can retard the timing for boost, without that u will develop engine knock
If you buy the twin turbo setup it will work but you won't pass smog,(you may blow clean through the machine, but you will fail visual everytime....
the only way the twin turbo setup will work properly is send ur computer out to get retuned or run water/alchol enjection, this will make it possiable to boost more than a few lbs (2-5lbs) without retarding the timing..... I say get the twin turbo setup and get the water injection, boost 5lbs to start then, go for up to 10 lbs ish if the engine comes with forged crank, but atleast forged pistons stock internals which I believe it is, ull need bigger injectors for 10lbs
