Possible build? 90 psi 2.2 ecotec?
So I'm curious to all the l61 owners I'm thinking about starting a build is there anyway to build an engine with 90 pounds of boost. My guess probably not. If I did build this what parts should I be looking for to handle 90 psi of boost. Plan:
Engine bored 30 over bore.
Eagle rods and bearings
Wiseco pistons 8:1 compression (drop in compression)
Billet crankshaft 4340
Supertech ported valves
82lb springs and retainers
Valve seals (no idea yet)
Competition camshafts (strip cams or racing cams) not fully decided.
Now would I need to have a Darton sleeves installed. What should I be looking for to push 90psi. (Actual psi 80) but 10 just in case anything goes bad. Will I have to nitro it, or could I use high octane gas. 97+?
Any info would be great considering I'm starting this ridiculous build soon.

Okay maybe I wasn't specific enough I'm running the super at 20 psi and the turbo at 30psi... What's the absolute pressure I figured it out last night it's was 5.4 absolute pressure to psi was like 78 psi of boost... Judging by the mathematics... So seriously how do I get the car to take 78 - 80 psi of boost... I'm highly thinking of darton sleeves anyone have another idea...
And stop twacken yourselves this is literally my first forum. Me and 3 other are helping with the build and I got a rough idea what im getting into. And seriously if you can have a 2000hp vw golf, 4 cylinder I'm pretty sure an ecotec has the same technology around.
Stop your cursing if you have nothing good to say please knock it off go troll someone else stupid forum about ricing there cobalts, sunfire, cavalier.

If your serious about this look at the 1400 ecotec dragsters as well as a couple if the engine build threads. Highly recommending looking at mr.b's stickied thread about the design of our cylinder heads and it's limitations since it appears that our heads are the limiting factors of our engines.
A twin charge set up won't be needed and may cause a lot more issues than it's worth

You'll most likely lift the head. Also that blower will become a restriction. Most likely need a compound turbo setup and deep pockets to get 2000hp.
I'd also like to see some proof of said 2000hp 4cyl VW, I know some evo guys can push over 1200 on custom turbos with the 4g63 block

Car throttle has an issue top 10 super sleepers. That's were I seen the vw. YouTube or Google it it should still be around. And yes I've seen that badass fmsr head... But I'm worried why are they the only ones that can make a head that pushes 60 psi + ....
Now someone please tell me I got my number wrong but if my blower is going at 20psi and my turbos kicken in 30 I don't actually get 78psi do I?

Oh and I'm sticking with twin, super hard tune. But frankly I don't care, I just hate hate hate turbo lag.. The bigger the turbo the worst the lag.

Actually if you look at the mathematics (there's a thread on here you actually can't just add them together.... ) when I have a desktop in front of me I'll quote the link to it.
Actually here's the thread https://www.cobaltss.net/forums/adva...ormula-132146/

Once you hit the 350whp/350wtq number in these fwd cars you're fighting for traction in a gear below 3rd (those in the 500 category have issues in 3rd), you go to 2000hp you will be looking at a completely custom front end to handle the correct width tire to put the power down.

Even if you were able to get all of that power out of the engine, why bother? You'll end up with a really expensive smoke machine. Every bit of the drivetrain would have to be replaced. Totally new fueling system. Etc. Etc. There are much better ways to spend your money.
BTW, FMSR is a joke. Literally.
