Bolt on turbo upgrade
#21
XXL put the K04 on his, but is no longer on the forum, haven't seen him on the cobalt site either. If I remember, he said is came on a little late--not much more at the low rpm's but held nicely all the way past 6000, with a peak at 5500, I think... but he was running all sorts of mods... HPT, Cryo2, MethInjection, custom dual exhaust, dual CAI's, etc.. But the last post I saw from him had him fighting a nasty wiring problem.

I'd be curious about the first couple of guys to bite the bullet. Add tranny parts, half shafts and other weak links to the bill, cause you know a lot of the stock drivetain parts can't stand the strain[especially a auto trans], then see what the total bill for parts will be.
When you dance,someone has to pay the piper. Been there, done that, got the t-shirt to prove it.
Also for a DD, traction on the street will be non-existant with 400 HP. Tire spin means "You lose sucker".
This will be worth watching in the future. "Moon"

I wonder if companies like Level10 have looked into building a strengthened auto tranny for guys like me who'd like to have that kind of (350-400) power but are limited by the auto's limits...

I will be one of the first (if not the first HHR SS) to run the turbo if the results come back good

I know someone that's ready to buy it right now, but he doesn't have a hhr. he just got his cobalt and is already winning trophys at the track with a tune gms1, dejon intake, and hahn 3" exhaust. but he also has ordered full boltons for it, just waiting for them to arrive.

For that kind of power; I'd be willing to bite the bullet cost wise to build up my Auto Trans and get better rubber. Even if it destroys my warrenty. However I dont want to destroy my entire HHR by getting the turbo and nothing else.

Does anyone know how these hold up in our cars or in the TC Cobalts?

Someone lied to you, our engine is a very high tech piece, probably one of the most high tech engines GM develops. You don't need to worry about anything till over 500 whp. There has been a few cases of broken piston skirts like 8 out of thousands of tuned cars (probably defective castings).
Unique LNF features[1] include:
a twin-scroll turbocharger
cam-driven high pressure gasoline direct injection fuel system
dual camshaft continuously variable valve timing
sodium-filled stainless steel Inconel exhaust valves
low-friction cast aluminum pistons with oil squirters
forged steel crankshaft
forged steel connecting rods
cast stainless steel exhaust manifold

However, the concern comes in the form of structural breakdown of components occurring as a result of time and stress. It's not just one or the other. My attempt was to caution if the car is driven often, with this much power, parts have a tendency to break faster.
