I would say it was all done with computer programming , if that is true about the 325 HP... unless you are going racing you will have plenty of power to get into any trouble you may want to get into...

Reports of the early test Solstice GXP with this engine said it was producing 325HP and that it was cut back to 260HP for production.

Early reports were not 325HP. The "Weekend Racer" concept at SEMA had 325HP but that was not the DI engine. The only way you're going to get more HP out of the DI Ecotec engine is with more boost and/or better flow. Intake and exhaust mods can really help a turbo car if it's choked. The problem about adding more boost is that you'll need bigger injectors and more fuel pressure at the very least. Considering the turbo is fairly small and putting out 20psi already, the stock turbo may be at the limit of its efficiency.Sky_Flyer said:Any ideas on how to get more power out of the 2.0L DI turbo engine than the rated 260HP?

I did some searching to refresh my memory and you are definitely right that the prototype vehicle with 325HP is the "Weekend Racer" and not a GXP prototype as I thought. However I am still not convinced about the engine. The specs listed for the Weekend Racer powerplant say 2.0L turbo charged four cylinder. It does not say whether this engine is Direct Injection (DI) or not. Seems like if it was 2.0L that it would be the DI engine.Mallard said:

Does anybody know for sure??
Look at the pics of the engine. The intake manifold looks to be from the regular ecotec (non-DI). The intake pipe enters the manifold from the top, whereas the GXP engine has the intake pipe enter from the bottom side.Sky_Flyer said:I did some searching to refresh my memory and you are definitely right that the prototype vehicle with 325HP is the "Weekend Racer" and not a GXP prototype as I thought.

Mallard, where are these pics? All of the web searches I have done only come up with exterior pics of the car and a writeup, no pictures of engine or interior.
Please post a link. Thanks!

Interesting pictures, thanks for posting them. I see what you mean about the intake, this still leaves me with more questions than answers though...
Several souces reporting on the SEMA show list the engine as a 2.0 liter, which makes sense because apparently a square bore engine (bore=stroke) is better for turbo charging. So is this the port injection engine with a smaller bore, or the DI engine with a different air intake that aligned better with the intercooler that they chose to use?
Another question is if this is a port injection 2.0L engine that is making 325HP, than could the DI 2.0L make more than 325HP with tuning and/or turbo mods?
I also wonder if pump gas is still being used to get to this power level?

The Cobalt SS/Ion Redline and the Saab 9-3 engine are all 2.0L and square bore/stroke. They could have taken the short block from a number of places and remained port injection. Sadly all that aluminum covers the engine and turbo or else there would be more evidence. The best bet would be to look for more pics of the intake manifolds on the cars I just listed.Sky_Flyer said:Interesting pictures, thanks for posting them.

A square engine is not better necessarily for a turbo, but it is good for a high revving engine.
I think there is a point where you have to change pistons, rods, e.t.c. The stock engine and tranny can only take so much even if you have any lean/rich conditions. Not sure where that point is. My goal would be 300 and that's it.
I would like to re-create the Ford RS 200 with it but hey

The easiest way to get to 300 HP on this engine is a larger turbo back exhust, larger intake system, and more agressive caming (with a PCM flash). Basically the only thing that would take "Work" is the exahust system, the rest of it could be done by joe blow with a wrench and socket set (yes I have completly taken apart and rebuilt an engine with a wrench and socket set and maybe a few tricks.... )
