Default LT1 Impala Turbo Kits?

I tried to search and if I have not be thorough enough I apologize.

I am in the market for a turbo kit for my impala(1995). Twins preferably, capable of 500whp with built 350, head work, cam. (600whp would be ideal but I want to remain beyond realistic as not to be disappointed)

I have found a couple of kits but was wondering what kits people knew of or recommend on this board and what experiences have been had with them.

Thanks in advance for your help.

The one that has caught my eye the most is the HP Performance Kit.

It appears to be very inclusive and reasonably priced but I would like to see dyno graphs from the setup which are unavailable through their website.

Also Turbo Technology Inc. however their kit is a single turbo.

But I am open to more options from more informed members

what's your reason for wanting twins? i've got a single 76GTS and spool is definately not a problem. i believe a twin setup is quite a bit more expensive also. just food for thought.

Search for RMCR and Impala SS. That's Rocky Mountain Competetive Research.

I could be wrong - they might only do blower setups.

Also try Nelson Racing.

My reasoning was simply that twins would spool quicker. My experience with larger turbos has been on small engines so as you have indicated I am slightly misguided about V8's and turbos.

Also, car is not being built for racing so I thought twins would allow it to maintain a more linear powerband to preserve street manners.

w/ the 76, i'm pretty much at full boost by 3k rpm. it's a blast on the streets, as long as it hooks. i just don't really think twins would've helped my build much unless i went w/ pretty large twins.
