OK, so lots of people are not liking the nitrous. I agree. Wouldn't this be better and easier?

1. 2.8" pulley
2. Bigger fuel injectors (60lb.)
3. GM extruded honed manifold w/ GM cat-back exhaust
4. Reflash

They already have everything except the 2.8" pulleys but that's easy.
What do you guys think?

 

I voted YES, as long as it would still be under warranty. Otherwise, I would just go INTENSE and be done with it, which I might still do once that warranty runs out.

 

i agree. the nitrous thing isnt cool to me. im still wanting to know what gives the Time Attack car 283 before nitrous. i thought the stage 3 was a shot of nitrous added tot he 245 for stage 2

 

^ Exactly my thoughts. The things that GM lists for Stage 3 besides the nitrous would not add up to 283, unless thats a crank hp number..

 

I don't understand why GM would even think of using NOS on their engine? I mean maybe their staff is watching Fast & the Furious and think thats what GM peps want? Personally I am sure there are better methods to the maddness, like twin charged or something of the sort.

 

that setup was intially rumoured to be GM stage 3

BTW I voted yes

 

i agree on no nitrous.... idk about that hp number either... personally... i think nitrous in any fashion is foolish and way overpriced.

 

id be MUCH MUCH happier with that rather than a package that uses the laughing gas and will make thw cabin 100 degrees plus in the summer.

 

I voted for making my own as most of you know I have done. I have ordered custom badges calling this "Roddy's Stage 5.5" which is part inside joke and my favorite number - 5.

You have to consider that the disabling the A\C works if this is used as GM intended, off road only, meaning race tracks not 4x4'ing.

 

All those parts can be perchased already, and the extrude honed header is worthless, Unless there was a major discount on the kit then I would rather make my own set up with a better exhaust system

 

I say make my own but I want that bigger better heat exchanger if it does come with one hope i can part it out

 

Sorry but thats not anything close to a real stage 3.

 

Twin charge TURBO...

 

come on Zinner explain yourself.

 

Well I would need to see pricing etc. but given a choice between the two I would go with your plan. Bottles are for babies LOL. no really I think you should modify still you are spent then put on a bottle. IMO. I voted to go on my on to make mods. then I can come up with something that works for me.

 

I think another reflash, a fuel pump, and cams would honestly be a good way to go. I dunno how goo dthe SS/SC cams are stock or how much power that can be uncorked that way. But there are still other ways to get mor eperformance out of it without squeeze. I honestly think GM is doing the nitrous because it will cool the intake as it expands mainly. Hell everyone here knows the heat exchanger is lacking once you mod the car and begin to run it hard.

 

Whoaaa there, you're putting way too much faith in a GM dealerships service bay. The local dealerships here aren't up to par with a Stage 2 kit, much less anything involving anything close to actual mechanic work. I've seen way too many scratched heads and really offended sounding "I've never heard of that"s.

 

I voted create my own..just because im going my own route with HP. and what did you mean by "bigger injectors?" 42's or the 60's? I do agree that the set up starting the thread is a better idea than no2. No2 IMO is a bad idea..

 

Good point, though the fuel pump even an idiot can do. Swapping pulleys isnt' gonna give you a whole lot unless you cool the charge though. Hice the nitrous. I bet it'll eb some real small ass shot and the whole system for injectint it will be sealed with epoxy or some **** so you can put in a larger jet without them noticing.

 

I Concurr.....

 

I'd think something more like this:

1. 2.7" pulley
2. 60# injectors
3. GM extruded honed manifold w/ GM cat-back exhaust
4. Reflash
5. One step colder plugs (NGK BKR7EIX)

This would still keep the supercharger under redline and boost numbers from stage 2 by about 25 HP and 30 TQ which would still safely be under the stock engine limit of 300 HP and the transmission safe limit of 260 TQ.

 

I think stage 3 is going to need some new parts like the 300 HP LSJ build.

Forged Pistons
Stronger Valve springs
Neutral balance shafts

The HP different between a 2.8 and 2.5 is really not much, it's just a difference in the torque.

You are going to need to break the 300 WHP limits. (which I think the 300 HP LSJ will do)...

 

Yeah I was thinking 60lb.ers for injectors. This way if you had an intake or full exhaust and what not, those injectors wouldn't even come close to maxing out their duty cycle.

 

but also if its a GM licensed stage kit they have to make it affordable and Do-able... the stg 2 kit isnt much different from stg 1, so they probably wouldnt change much for the stg 3. make it be like $1200 + install or $500 + install up from stg 2 (since its a new exhaust). You guys are acting like GM actually wants to do something that benefits us more than them... the manifold might suck, but its GM.. They wont put in NGK BKR7E's cuz they aren't GM... Pulley, Injectors, Tune, and the exhaust idea sound pretty good for GM. All of us know the potential of these motors with aftermarket stuff, but GM isnt trying to show us potential, they are trying to make money by giving us what they "think" we want...

 

Exactly. This stage 3 would make more sense.
