We are looking into the possibilty of bringing more potent turbos to the LNF market. If we design these new turbos from scratch, we can include new features and push performance levels far beyond anything currently offered without requiring a whole new turbo kit. To start, we would cast a new exhaust housing that bolts to the factory exhaust manifold and O2 housing. This would allow people to keep their upgraded downpipe if they already purchased one.

The purpose of this thread is to find out:
How many people would be interested in a fully upgraded turbo option?
What features would be popular?
Wastegate options?
What max HP potential should we target?
Would more people be interested in a group buy? Or would more people prefer to wait for completed product and pay retail?

Let me know what you guys think.

 

What will you guys do about fueling? Just curious on your ideas.

 

On the note of retail vs group by. I'm sure noone just wants to pay retail if they have an option of lower cost.

I am looking for a good kit myself. Around 450 hp and 500 tq. I'd possible. But I know I will have to start building by motor. And new clutch. Ect.

I am interested. But what type of pricing? Fuel mods? What is required for these numbers.

 

if i had a tc I would be for sure interested in this idea.....but being as I dont I will just keep my mouth shut.....


free bump

 

X2... Very good question.

 

Fueling is something that has to be addressed regardless. I'm sure we will be investing a lot of effort into this as well. Then there is the clutch, and everything else requiring upgrades. It sounds like we need to get busy as a community if we want to put down impressive numbers.

 

i want 400 hp

 

Pistons anyone?

 

BTF has already produced a GT30R/35R upgrade that is basically the same thing.

Bolts up to factory DP location, factory Charge piping location, factory Air Intake location and directly to the factory Exhaust Manifold.

 

^^^ TRUE

I wanna clutch lol...and fly
help

 

pistons are almost to market, i was in contact with several suppliers for a part search for a local 30r LNF car.

however, if you can keep KR down and out then these hyper-cast pistons will carry a large cylinder pressure. KR will destroy them in a hurry tho.

fueling is the main issue, with this car relying on available fuel load per stroke time (intake only) you quickly hit the point at witch a much larger DI injector is needed.

 

This will surely need a lot of effort, finding higher flowing gdi injectors seems impossible now.

For what? Have you noticed any failing yet?

 

I'm pretty sure theirs is more of a conversion than it is a direct bolt-on. I'm not knocking it, just saying ours would be manufactured as a direct bolt-on.

 

good job there! lol. im sure i sound patronizing...but good job not bashing the other product

More options are always nice. As with any turbo swap, keeping the spool time pretty short would be a massive plus (look for more twin scrolls?). this beastly low end power from the LNF has spoiled a lot of cobalt owners, and im sure they would love to keep that low end power. Obviously, no one expects a 500hp turbo to fully spool at 2000rpms, but you get the idea

 

Are you implying using a stock turbo with a bigger compressor/turbine wheel, or a totally different turbo that still bolts up to the stock parts?

 

500+hp bolt-on, wow.

Like has been pointed out I would be much more concerned about sourcing/developing an appropriate fuel system, since that will be the largest hurdle imo.

Whats the logic behind developing a new hotside that bolts to the stock parts? (as opposed to fabricating a tubular manifold that uses readily available turbos)

 

About the same logic as destroying the stock EVAP system to run a vacuum line to the fuel tank, as opposed to just running a return line.

 

Huh? whats going on with the EVAP system mods?

 

the only down fall for having lots of power int he low rpms is that u just roast ur tires like no tomorrow on a fwd if it was a rwd then it would be good, it would b like the supras (ok mayb not exactly like supras but u get wat i mean) and cars that are for roll racing. people will think that they hav u and then spoooooool and here comes the cobalt lol!

 

We would obviously have to make a trade-off there. The tiny exhaust wheel in the oe turbo is great for instant spool right off idle, but backpressures are far beyond reasonable levels long before 500HP. I'm thinking we would offer different combinations based on power goals.

A completely different turbo that still bolts to the factory manifold and O2 housing.

Easy bolt-on upgrade, possibly lower overall cost. Factory look for those who prefer it. You can still add a tubular manifold if you prefer, but the factory manifold will support 500HP, so there isn't much reason to upgrade there.

 

No offense taken It is direct bolt on with full boost by 3400rpms with yet more tuning to come


Have a looksie https://www.cobaltss.net/forums/2-0l-lnf-performance-tech-153/gt3076r-kit-complete-149712/


Still more mods to come (Converting to a blow-thru style MAF, VTA BOV and custom Intake)

 

I've seen the pics. It is not a direct bolt-on. It requires some type of adapter or replacement manifold. I'm pretty sure it also costs a lot more than our replacement turbo will.

And please don't spam in my thread.

 

Not trying to spam your thread at all. Just trying to pass on some info. And again, it is direct bolt-on.

 

all your bolt-on are belong to us

 

You posted a link to a competing product. Hence, "spam."

So you are saying that they have a turbo that bolts directly to the factory exhaust manifold and stock o2 housing with no adapters required? I ask because it looks nothing like that in the pics.
