One of the obvious is going to be at least forged pistons. I'm not sure how the turbo bolts up but you might have to lose that header, and if you have a down pipe that too. I guess it all depends on how fast you want to go and how fat your wallet is. If you do pistons you'll have the head off, I guess port it while it's off, why not cams when it's off too, then more tuning? See how easy $$ can get spent?

twincharging is a bad idea if you just wanna go fast.

Please refer to the quote from Hahn, as to why you need to reconsider your desire for twincharging.

Let me begin by offering an update on our progress to date with the TwinCharger system. I've worked on this on and off for over a year now, and while it's been extremely educational, I am unwilling to release it to the public in its current state. Why, you may ask? Well...it's just not ready for prime time, in that there are a number of rough edges that I have run out of time to smooth out. I'm a madman for details that make our products exceptional, and this one's just not up to snuff. For now, I've moved it to the back burner while we develop other systems we consider to be more viable.

For competitive reasons, I am tight lipped about just what I don't like about it. Suffice to say, we've come to a point in the development process where we are doubting that the complexity and cost of the final result will be justified by the results achieved. I think I have better work to do with this car series, work that is only being delayed by continuing to flog this (admittedly bizarre) solution. So, mothballs for now. Will it return? With the discontinuation of the supercharged car looming, the chances grow dim.

As some of you may have seen on these pages recently, our 2.4 turbosystem is most definitely ready for prime time! I agonized about releasing this system, for it was my sworn intention to get the TwinCharger out there first...since it was started first, and I didn't want to start 'camp wars' between the 2.0 SC and 2.4 groups, I delayed the intro of the 2.4 systems for quite some time. But, as many of you may also know, we've attained significant success with the 2.4 in our Solstice/Sky turbosystem line, and I could not hold back on the 2.4 'Balts any longer.

So, while we did manage to get some tasty exhaust components out there for you SC guys, the next product to emerge will be...the all-turbo conversion. We've been quietly advancing this setup, and will have systems ready for the public this summer.

I'd request you folks to ask questions on this new 2.0 turbo setup, and I will answer those that I can. I humbly request your patience with me should I decline to answer a particular question for reasons of competitive secrecy.

As for the #4 cylinder issue...my opinion is this. The problem is the #4 cylinder running leaner than the others!!

Wow! What a revelation, eh? Ah, but here's the rub...it's not getting less fuel. It's getting...more air. The design of the 2.0 SC intake manifold is simultaneously a packaging feat and an airflow disaster. I give props to the engineers who packed so many items into such a tight space, but they never intended it for much more than stock airflow, and I find it to be one of the most convoluted, odd flowing pieces I've ever come across.

Let's start here. Your turn!

Twin charge is good for originality and shows. But since there is a kit made, it kinda takes the WOW factor out. Wanna see something thats wow, go to jbody.org and look up John F I think thats his name... he twincharged a sunfire...that was sweet.
