Hey guys I'm new to this tuning stuff and have a few questions to ask. First off here are the parts I'm looking at:

Comp Cams 113450
ZZP Long tube header package with offroad downpipe for 2.5" exhaust
TWM Short Shifter
GMPP Exhaust
GM Stage 2 supercharger and change to a Smooth Flow 2.9" Pulley
K&N Typhoon air intake
ZZP heat exchanger
Snow Performance MAF Stage 2 Water/Methanol Injection Kit

My questions are if this is a quality build list, What would you guys change about the build, and how much power would I expect out of this build?
Any help would be greatly appreciated thanks again!!

I'd go with ZZP s2 cams so you don't have to mess with lash adjusters.. Definitely get an interceptor and wide band gauges if you don't already have them.. Not sure what a "gm stage 2 supercharger" is... I'm assuming you're talking about the gm stage 2 kit? Thats just a pulley, injectors, and a tune.. You don't want that. You are gonna need injectors for all of this though. Id go with 80's

1. you need injectors
2. do you know what tune you are getting?
3. what are your power goals?
4. you dont need cams with this set up
5. i cant tell you what you will gain because this is missing a lot of info.
do yourself a favor, read through the forums, go to the lsj page and read all the stickys. theres
a very a good modification thread you can learn a lot from there.

TStone- I will look into the interceptor and wide band gauges are there any two that you would recommend? and I will go with those cams. Why wouldn't you do the stage 2 kit? cause with changing the pulley cams and injectors won't I need a tune to go with it?

07LSJ- the stage 2 kit comes with 42 lb injectors and tune the Mod guide says the 2.9" pulley will work with 42lb injecors and I have also read that with the 2.9" pulley the gm tune will work for it. And I wanted to get cams for the torque benefits or is it not gonna help much at all? and I would like to make anywhere from 260-290

ehh, it will probably help a bit, but for the money maybe do something else???
go 2.8" pulley. try to get 60# injectors. the zzp longtube headers w/ dp. good intake, and a good hp tune you should be around 245-260whp.
to get 290 you're going to need e85, aggresive tuning and maybe even ported head.

Or TVs..

I would recommend the interceptor and a wideband. Interceptor is 1 gauge and a wideband is another gauge. And the stage 2 kit is pointless if you're already buying a pulley, and the injectors it comes with, won't be enough for you. So, you might as well buy a pulley separate and buy injectors separate.. and yes you'll need a tune. Look into going with a custom tune via HPTuners.. Look for someone local that can tune you or travel to someone with it, or buy HPTuners yourself and have someone remote tune you. But along with the cams, you'll also need neutral balance shafts (or balance shaft delete) and valve springs.. But honestly, if all you're looking for is 290whp.. Just get a TVS, basic bolt ons (intake, exhaust, dual pass), and throw some methanol in there. With a solid tune, that'll put you well over 290whp.. You can even forget the meth and probably break 290..

What brand of injectors would you guys recommend? and I have looked at the TVS just not sure if I would want to bolt that on or build up the m62

What is the advantage of balance shaft delete btw?
You"ll need cooling mods too btw, not just heat exchanger and meth. Well i guess you could do well with meth but you'll see, if its hot outside and you're temps get high, you will hate your car because it will get really slow
For the low price, i would recommend a zzp dual pass and phenolic spacer. Well worth the price

kmcnish

Also what if I did the zzp stage 3? it comes with pulley, injectors, dual pass, tune and tensioner

i have that kit and it is amazing. although if ur debating building up the m62 or slapping on a TVS... go TVS all the way. u won't regret it. but as stated before u will want cooling mods. zzp dual pass with option b, heat exchanger, phenolic spacer. intake, headers and dp so it can breathe and u'll b good and a tune obviously

insylem

Id go with the ZZP intake instead of the K&N.. My K&N was rubbing my brake lines
Both intakes dynoed the same anyway on my car.

kmcnish

Thanks for all the help! What kind of injectors should i get though if i dont do the zzp stage 3 kit, and like micogab asked what is the benefit of a balance shaft delete?

Melon

zzp sells just the injectors on their website. u can just pick them up separate if u choose to go another route

TStone

Just skip the stage kit.. Don't even worry aabout it. Forget it. Just order a pulley and the injectors from ZZP. But a Heat exchanger and the dual pass endplate will be beneficial. Also, look into a phenolic spacer. Can never have enough cooling mods.. And the balance shaft delete or neutrals is benefical because it's less weight, therefore less rotating mass when you're spinning your engine to higher RPMs.

kmcnish

I am going to just skip the stage kit completely cause it would end up costing more money. And I think I will just skip the cams as well if there won't be much benefit. Don't wanna spend that kind of money if its not gonna do much for the car

TStone- what mods do you have done to your car other than the TVS. i watched a couple of your videos and your car sounds great!

TStone

iTrader: (2)

Oh Cams will benefit you TREMENDOUSLY.. it's just they require neutrals or deletes.. and I have a 2.6/TVS, 80lb injectors, 14gph Nozzle for my meth, ZZP S3 Heat Exchanger, Dual Pass + Option B, ZZP 3” Intake, Bad Mab Header, ZZP 3” Catted DP & ZZP 3” Cat-Back Exhaust

kmcnish

would the neutrals or delete benefit more though?

TStone

iTrader: (2)

Deleting the balance shafts all together is the best route. Doing neutrals is just simpler.

kmcnish

Alright and I'm gonna need valve springs and rocker arms as well correct? or could I do without?

TStone

iTrader: (2)

If you do cams, you need valve springs. If you don't do cams, you don't need springs or rocker arms.

kmcnish

how much power do you have with your tvs?

TStone

iTrader: (2)

No idea. I would guess around 330whp.. which is not enough

This thread has all the info you need.

TStone, I almost have the same setup as yours, some parts still not installed tho So just wondering, for our setup (I'm planning on running on E tho) what kind of improvement could we see with cams? I'm guessing we could also rev higher also (8000+) and shift less often in a quarter mile? Thanks
