Hello,
I am new to forced induction.
I have a 347CI LS1 that I will be installing a forged bottom end on.
What is the most powerful turbo I can use on this engine?
Thinking 76 or 78MM. I am thinking Turbonetic T76 or TC78.
I was told that even with these turbos I dont want to push over
700RWHP due to backpressure.
Can anyone tell me who has a great deal on a turbo head unit?
Any wholesale or group buys?

im also looking to do a 347 with a turbo. i was thinking about a tc78 but i dont know if that will be quite enough, and i think the pt88 might be a tad to big and laggy. im looking to spend around 1k on a turbo, also my car will weigh a max of 3200 lbs. ill have a 4l60e. whats a dam good turbo thats bigger and is as advanced as the tc78 but not as big as a pt88

I would get a borg warner unit. S475, 600 bucks, capable of 950 or 1000hp. http://www.forcedinductions.com/productsborgwarner.htm
Dadkins on here is using an S372 on his GTO and making 825+ to the tires with a stock LQ9 long block.

You will not beat the spool up characteristics, compact size, price, and power potential of the TC76 or TC78. They are perfect fits for 347-370 cube LSx based engines. I have persoanly pushed these turbos to thier limits. Been 9.70's with a TC76 370 combo. Same car later made it to the 9.20's using the same TC76 370 combo.
The TC series of turbos are rated for 3" Down Pipes. I never had back pressure issues with my setup.
