I'm looking into a turbo winter project.
Which of these or other system is the best for a non forged (at this time) motor making 6-8 lbs of boost thru the stock motor(will lower cr thru a head swap 9.5-9.9 cr)- looking to get to only 500-525rwhp to have the motor last..

any input is apriciated...

 

TTi all the way.
The reason why I say that is due to the overwhelming majority of the guys who run the kit are absolutely satisfied.

The PTK kit has a TON of power potential but you have to wrap half the ****** engine in heat wrap to keep it from melting everything in sight.
Not my cup of tea..

 

If I ever get a turbo kit for a vette. It will be this one!

 

The APS kit looks simply amazing (And I kinda agree with you) But it hasnt even hit the road in production status yet.

I have been the test mule before, and I will NEVER do it again..

 

TTIx...battle tested (read: all bugs worked out). Powered more than a few C5's to 9's. Gets 25+mph, daily driver type reliability, oem quality (cast manifolds)and packaging. Couldn't ask for more.

 

ok, sounds like the TTI get more than one thumb up... Any pictures of the turbo/motor???
Thanks!

 

here's more on the TTiX, I'm thinking about ordering this kit as well...

The PTK isn't for everyone just as much as one kit isn't the best for everything. It makes for a great option if your a stroker or bigger cubes, but for stock cubes and those not willing to invest alot of time fiddling, the APS or TTi will do.

And yes there's underhood heat. That's what extractor hoods are for. Also, with the right preparation (and it doesn't always require wrap ) it'll be troublefree for the long haul.

 

I agree, I would go PTK as well. More power potential with that kit then any other right now.

 

What upgrades areneed for these power levels with the TTI X Stage...

1. up to 550rwhp- head to lower CR and clutch??? What else if any.
2. 600 RWhp?
3. 650rwhp?

 

1. MSD boost a pump(will work up to 530-550rwhp), 60lb injectors, clutch(depending on how you drive), stock heads will do, meth injection to be safe. 7-8psi should make 520-550rwhp..

2. ECS fuel system for 2004 FFS fuel system(good up till about 900rwhp) and the above plus 10psi.(stock bottom end not safe here). DTE transmission brace and hardend left output shaft recommended.

3. 650+. Most hit 700-800rwhp at 14-15psi. Ported heads, forged 346 bottom end, turbo cam, etc. Also oil cooler would help.
