Hello everybody,
I've recently got my car back from BYT after installing an AutoWerks 55/57 kit along with a lot of other things, but leaving my engine internals stock. I wanted to ask a couple of questions to you guys because even if I will enjoy my car like this for a while, if I decide to change the internals in one or two years, I will have to start saving my money from now, since between parts and labor it will be several thousands.
If I do it, I'm thinking to build my engine entirely. Thinking to get the head/cams combo from zzp along with the valves, wiseco pistons, and Carrillo H rods.
First question: are the sleeves recommended? For example, the Darton sleeves?
Second question: at that point, would my 55/57 be too small for the power I could actually get (it is rated up to 535hp) or I should swap it with the 62/62, since Nick told me that if I change my turbo with the 62/62 I don't need to get another kit because it will fit with the parts that came with the 55/57 kit.
Thank you guys all
Christian

 

450 450 26psi max is what I say this engine is good for. You don't need to resleeve the motor. Buy a zzp crate motor and swap it. A 6262 is too laggy, I won't do it. I think your 5557 is already too laggy lol. But to each their own.

 

Personally I would build the motor for piece of mind....pistons, rods, cams, etc. I also wouldn't do the Carrllio rods cause they're too expensive

The ZZP rods are damn good as well and half the price and will still hold a good amount of power

The turbo that you have is good enough for 500 with the right tune, I'm pretty sure 500 would be a load of fun to so no need to go bigger

 

Build motor, go bigger turbo. Don't forget get fatter rims and tires maybe need to widen front fenders

 

Just don't forget that forged pistons aren't necessarily super street friendly. You're in NY, where it gets pretty damn cold, so I hope you don't plan on using it for a street car in the dead of winter. It depends on how you're using the car too, like short commutes, etc. Talk to ZZP. They're in a damn cold place, so they can give you expectancies on how long a block will last. Most of it will be up to you, the owner.

There is a reason why so few manufacturers use forged pistons, even in sports cars. They need their cars to work in Alaska, and Death Valley.

 

Idk about a 6262 a 5857 would be nice they are rated at 605

 

This. My 5557 I think is too laggy haha I couldn't imagine a 6262. Unless you are looking for purely a dyno queen, i would stick with the 5557 or 5857 as stated above. You have to keep your power streetable to an extent!

 

can we see some footage of lag please

 

This was early in the tuning so its spools faster now...but its no stock turbo spool time lol

Cobalt SS 5557 60-100 - YouTube

 

We were seeing full spool just over 4k

 

damn 4k of lag :/. Must have some crazy powerband.

 

Its not like there is no power and then all of a sudden a shitload lol. The car still drives around nicely and has good part throttle power. You just dont get FULL spool until 4k.

 

Thank you guys all. I've got the 55/57 because AutoWerks told me (also as shown on their website) that the 58/57 was rated to 575hp, only 40hp more than the 55/57, but the boost lag was going to be 300 or 400 rpms higher, that's why I've chosen the 55/57. Since my initial idea was to build the engine eventually, If I would had known that is is rated 605hp I would had picked the 58/57. But thanks all for the advices. Btw, anyone knows how the 62/62 is rated to? And eventually at what rpms should have full spool?Wangspeed: No I really wasn't planning to drive it a lot in the winter. But thank you for your advice, really appreciate any input that I get from the community. My idea, since I have another 2009 SS just like this, was to make this actual car a fun track car and keep the other SS for daily drive (it has Hahn catted dp and cat-back, Injen CAI and upper IC pipe, and a tune. Measured 315hp at the dyno).
I don't know if selling it and get a cheaper car for daily driving, or just keep that for it. The daily driving SS (if I keep it) still has a 3 years loan meanwhile the one that I'm building is paid off, and I would like to sell it to extinguish it and get a car for like 4 or 5 thousands for daily driving. Still didn't decide what to do.

If you do do a larger displacement motor like you wanted to, that will help spool it up faster as well

 

Yes I remember you told me that. But how much more will it be to buy the 2.4 block and build it, compared to building mine?
