the pulley is a 3" & injectors are 42 lbs right? i tried using search but didnt seem to find the info

 

yes, that would be correct.

 

whats the smallest pulley you can run with the 42's? only the 3"? or can you do a 2.9 or 2.8?

thanks for info btw, im new to the sc eco world lol

 

Stage 2 is not 3"

stage 2 is just under 3.1"...

Stage 3 is 3".

On the stage tune, dont go any lower than the stage 3 pulley.

if your getting a custom tune, a 2.8 is the lowest you can go if your tuner knows what hes doing.

 

stage 2 has 42.5lbs injectors, and the pulley size is 3.065 to be exact. i know there are people here running 2.9 and 2.8's. 2.8 IS safe.... until you get to higher rpm's, like around 6,000. at that point you're maxing out the injectors. 2.9 i've heard maxes out the injectors around 6900-7000rpm, which is when the limiter cuts in anyways.

i'm waiting for a custom tune and 60's before i throw a smaller pulley on... though a 2.9 is tempting since i just did exhaust. lol.

 

stage 2 maxes the injectors over 6500 , on most 05~06 cars

 

so a safe way to go would be just do a 2.9 with 42's & a good tune? lol. is there a chart or a ruff guess what psi a 2.9 would kick out?

 

16 psi around there depending on elevation.

 

y would you need stage 2 your have an ls

 

im trying to get all the info all together because i plan on getting a M62 for it

 

why not just buy my car? i have a thread for it...

 

lol, i want to build my own. make it unique. but thanks tho & gl with the sale

 

eh...it was worth a shot lol

I'll stop thread jacking. A couple of my friends just recently s/c'd their sedan. They're actually the COTM this month. Feel free to PM them all of your questions. They will be happy to answer any of your concerns.

 

hey man im running a 2.9 on 42lb injectors i havent had probelm yet i got it custom hptuned

 

Skip the GM Stage 2..

Go with OTT stage 1! you will be glad you did!

 

or skip ott and gm and do a 2.6-2.7 with 60`s a h/e,exhaust and methanol.

 

If he has the means to tune it...

 

if he wants to go boom. He's (no offense) just an LS. Going stage 2 is already going to put him over the top, unless he decides to do something about his internals

 

the 2.9 with 42's & a trifecta tune on stock internals is much as i want to push it. (untill some day down the road ill get rods & pistons) i talked to vince (i think his name was) from trifecta & the tune wouldnt be a problem at all.

 

if u get that i would get another h/e mine get heatsoated bad i gotta get another one in few months

 

Oh, I didn't see that!

 

there is more then a few ppl running 2.2 blown with no problems on stock internals. like i said im not going to be doing more then a 2.9 with 42's & a nice tune. also im planning on running a zzp cooler not a stock one.

 

never said anything about running boost on stock internals. It's when you put an OTT stage kit on those stock internals.

 

oh ok, yeah i wouldnt do that lol. when that time in point comes i will do the motor up the right way
