now for the question that i have that im confused about.

1. where can i get the right spark plugs?

2. will the lsj H/E work untill i can get a bigger and better one such as zzp?

3. injector harness? iv yet to check out others how to's but how is this done do i need to cut the lsj harness?

4.. which option is best?

option b?
dual pass without option b and with a 2nd H/E?
dual pass with option b and 2nd H/E?

5. map sensor - heard so much about you needing a 2 but on alot of the list iv seen a 1? so which is it.? some of these how to's are confusing

6. do i need to get a better header/dp and catbak? eventually i will but for now?

7. should i get a tranny cooler since im an auto?

8. should i use 2.9 pulley with 42lb injectors? i want this to remain as safe as possible someone told me 3.06 pulley is good enough with my motor

thanks for looking and any info and help threw out this will be really appreciated. im hoping to have all the parts before the end of the year only bc i now live on my own and to every1 else that does knows how hard it can be to do mods and pay bills lol any1 with parts let me know thanks

getting a downpipe and exhaust would help alot after your boosted.
you can get NGK spark plugs from zzp
you need to cut the injectors connectors from the lsj harness and switch them out with your stock harness.
I will be going supercharged in acouple of months two but i dont think i will be getting a tranny cooler.
dual pass with option b and 2nd H/e would be the best,but you can still be good if you just get a second H/e .

Any Autolite spark plug that list for the 2.2L is 2 steps colder.I am running the Autolite Iridium XP.Anyone know of a copper plug thats meant for the 2.2L?(25mm reach,taper seat,2 steps colder)

Edit:I am a 2.2L on a 2.9 inch pulley just to clarify

would any1 mind explanin what the dual pass with option b with 2nd h/e consist of i understand how it works but any more info about it?

iv heard alot bout the zzp spark plugs so ill prolly be getting them. as for now im looks for parts seperate rather than a whole kit hopefully start this at the end of the year but if the price is right then of course im willin to buy now.

yeah the lsj injectors just to need be cut and two different wires need to be switch im pretty sure thats how it was done.

btw any1 who is boosted thats a 2.2 plz post up what else you have done performance wise to the car iv noticed that our cars can only handle like 250 hp without buildin the motor more so wouldnt you reach that supercharging the car and the tune? if any1 has a dyno sheet that would be awesome.

also if you have a list of the cost of the sc kit that would be great to so i can make sure im gettin good deals.

M62 SC, 2.8 Pulley,60lb Injectors,Injen CAI, Ingalls TD, OTTP 4thGen H/E, 2.25 Catback, Trifecta Tune..and now Im buying parts to build the motor..not sure of hp...Roughly around 1900$

heathkidder

iTrader: (20)

yeah my kit will def. be way cheaper than that lol ill make sure of it. i mean ill get the parts at the right price or ill wait is all. yeah u may wanna make sure ur hp isnt close to that cause once u go over ull start havin major problems so iv heard. thats why i wanna know what other ppl have done and how much hp there puttin out at those mods. so i know exactly what can be done thats why i think ill wait to do bolt ons after so i know how much hp i have left to work with

Good luck. My sc build has started. Step one put money in the bank. Lol

Glowbalt

True true, that's why Im not putting anything else on until my internals are installed..Then it's go time...It's good that you have that kind of patience

1LowLS

My SC kit was Free 99.I have full bolt ons on a 2.9 and tune.My buddy has a Auto 2.2L SC and he dyno'd 240WHP and i put like 3-4 cars on him.Im 5 speed.

heathkidder

iTrader: (20)

so you have the full bolt ons with sc and hes jus sc'd at 240 hp? is ur motor built at all or else arnt u worried bout sumthin blowing

my patience actually suck lol i have the money but i also have other bills i should worry bout first

heathkidder

iTrader: (20)

btw since im pretty new at this are there any parts i should be concered about when i buy it i know most of the lil things will be new bolts and gaskets but how can i tell if the m62 has been abused or the intake mani and such any1 have any info about that thanks

1LowLS

No he's fully bolted on as well.Everytime I go WOT I worry about it blowin haha.I usually drive it nice unless I need to get on it.Im on stock internals.....for now.Him being auto and me 5 speed i SHOULD have a little more power to the wheels.Unless its my gear ratio's giving me the advantage.

heathkidder

iTrader: (20)

iv heard that auto is better with this m62 though than 5 speed idk if thats true or not but i think ill do the build and get dynoed and if im close then im not gonna do any bolt ons unless i build the motor which i dont plan to do unless its a few years down the road
