Huge news, convert 3.6 255 hp to 3.6 HO 275hp

[B0000rt]

Which means the Direct Injection version of the LY7 will be 300+

Here's me hoping heh

Another thought comes to mind. This might be a good opportunity to do some port matching and polishing to make sure there aren't some steps getting from the intake to the heads and from the heads to the exhaust. With a good Gardner-Denver die grinder, some carbide burrs, and some Pam spray it'd be duck soup. You might make a difference. Like the senator said, a few billion here and a few billion there. Pretty soon you're talking real money. Engine mods are the same thing. A little here and a little there. Soon it adds up.

Quote of the day right there!

I disagree! There may not be a challange in building a LSx engine, but all the HP is fun for sure! I hear what you're sayin though. There's hundreds of places that sell all sorts of crap for those engines. It was cake making 400+ rwhp in my Camaro. No challenge to it at all. The only decision I really thought about was which cam I wanted for it since it was my DD. There's next to nothing out there for this 3.6, so it's good to see people like you looking for every option out there for the people who want a better performing CTS. Even if 20hp isn't a huge gain, it's still a start.

I think you're right here. I would bet this mod would benefit from a nice custom tune. I know LSx cars gain hp in stock form from custom tunes. (sorry if I reference LSx engines too much! Other than old SBC engines, that's all I've worked on!)

This mod + a cold air intake + exhaust + custom tune could = a nice increase!

undug from the past.

lets get back on this.

that makes me so proud!!

i claim the title of "the meanest"

[FL01SS]

Man, there's an A$$ Ton of GM vehicles out there now with the 3.6 in it. There's gonna have to be an aftermarket demand for performance add ons & mods soon. Right??!? Other than the air intake & cat backs.

This would produce CTSs in the 300+ HP range, wouldn't it? That sounds exciting.

[Kael]

can someone bug lindsey and start looking up part numbers?

This will require tuning the ECM correct?

nope. this is a change to the engine components making the engine itself more efficient.

[dannoaz]

New cams and head work are an old-school sure-fired way of making more horsepower. Port and polish is too. I am excited to see things going in that direction. It would be nice to see the aftermarket step up and make some cams. Maybe Camaro will fire this up?

Does the direct injection motor get all of its power from the injection alone? That's hard for me to believe. Maybe it gets some of that gain from heads and/or cams?

I dont understand this shit..."tear your engine down and buy a ton of shit to get 20HP"...like no duh...

[TotalEclipse31]

I just read this entire thread because I wasn't around when it was created. Very Interesting. I understand just about everybody's point of view. I would try this mod ONLY if A) The parts were cheap from a salvage B) There was an EXTENSIVE write up C) My car were out of warranty. Having a friend around thats a mechanic would be a plus as well.

[nickc50310]

Wonder how much it would cost to have a mechanic put this in. Next year I am planning nitrous. This plus a 100 shot...... DROOL!!

[TotalEclipse31]

Damn nick that would be awesome.
