turbo for a dd camaro im doing some looking around. may have gotten my handson a '95 M6.
i was wondering what a turbo would be for a 600 or so rwhp goal that can run on pump gas. also,what other internal mods would need to be done? i know most engines need a forged crank,rods,and pistons. but again...still new to the lt1 platform. dont know what can be achived on a stock bottom end. would it be doable on pupmgas at that goal? or would i just need like a set of good pistons?
ive been searching on this site and there is a library worth of stuff on an ls1 turbo setup. cant find much on lt1's that answers my questions.

The stock bottom end doesn't hold a chance in holding 600whp, unfortunately. You'll need a BUILT forged bottom end, very good heads, strong valvetrain, built transmission and rear, etc. LOTS of stuff need to be considered. This post could go on for hours but I'll leave it alone for now.

ohh yeah. i never expect to spend 30 bucks and be done. im asking now while i address other aspects. like fuel system,suspension,and everything else leading up to the build. i just like to do a lot of research before i even start to plan everything. i will more than likely buy another lt1 from the junkyard and build it in the Garage. while doing that i plan on building the car and getting it ready while i drive it. taking the weekends as time to intall various parts and upgrades. im just wondering basically wondering what would be a good turbo choice for an M6 car and the HP goal i have in mind

'68 427 BBC 4-speed chevelle. 720HP
not mine of course. but still. never had a problem with it on the street or the track. I helped him with everything and we became good friends,so he let me drive the car a good deal. even let me have the car for a whole day just so i could pick up a date.i owned an old silverado at the time....he didnt think it "helped" my cause.

Forged bottom.
Top End.
Upgraded fuel system.
Ignition controller.
Built transmission.
12 bolt, S60 or 9in out back.
Just a simple easy list that will set you back around the 10 - 15k range depending on what you pick.
Thats not even including the turbos and everything going in with the turbos.

Really the stock crank will hold that goal, that said with what that goal will cost what is an extra $600 or something on a forged crank? I would do rods and pistons without even considering trying to keep the stockers
IMO part of the reason you don't see a lot of turbo LT1 builds is the pcm's limited MAP capability. There is a 2-bar MAP swap available BUT it uses the same range as the stock MAP so you get much less resolution. It can all be worked around but it is not as easy as it can be with some other pcms.
All that said just over 1000rwhp has been done on a 355 LT1 with ported stock castings. Comes down to deep pockets and determination. Many folks I think try things and when they fail either refuse to see exactly what the problem was therefore not resolving it, or completely throw their hands in the air and scrap the project.
