how much horsepower would a CNC Ported Head, add to a ss/sc with ottp stage 1, cai, 2.7 pulley, exhaust??

30-40ish. depending on a retune to get the most out of that 2.7, and intake/exhaust

at the wheels?

you'ld be surprised how well our heads like to be ported

but since you already have the ottp stage1, 2.7, intake, and catback(guessing) it won't be THAT much. but it will definitely be worth the money. get retuned as well. get all you can out of that 2.7 and intake

thats what im buying
but i havent installed anythign yet, i was thinking i should install my intake, then exhaust, then headers, everythign else should come after right?

You'll pick up quite a bit... depending on the aggressivness of your tune, and such!

I would imagine 20-40 depending on valve, spring, and cam options!

sorry im new to tuning, what does valve spring and cam options do for the car, are they necessary? is it necessary to change my clutch if ill be pushing 300+ whp?

clutch is not necessary to change. but recomended if you ever plan on going to the track. valvesprings/valves are going to be able to hold a higher rev limit. cams will alow a higher lift/duration of those valves to allow more clean are to enter the cylinder, and more "dirty" air to leave the cylinder after combustion

im gonna set the rev limit to 7000, i want to keep my car reliable.

7000 is very reliable with a fully built head. i would probably set my limit at about 7300 and shit about 7000

a fully built head, im not so sure what that means... can you explain?

upgraded everything pretty much

i dont think im gonna do that, ill start off with:

1. injen intake
2.mandrel exhaust 3" (borla muffler)
3. cnc ported head
4.ottp stage 1 (2.7 pulley)
5. ingalls torque dampener

i wouldn't get the stage1 if youre gonna go right to a 2.7, i mean their tune is for the 2.8. and especially if youre getting an intake and ported head, youre gonna need another tune right away.

and btw, when i said "upgraded everything pretty much" i was refering to that as being a fully built head

whats the power difference between a tuned 2.7 and a tuned 2.8?

well its not much really. its just the fact that the stage1 from ottp is tuned for a 2.8 and really no other mods. youre going to have a 2.7, intake, exhaust, and ported head.

how should i go about getting a tune for that, how much would it cost?

find someone around your area that has hpt and is good at it lol

whats hpt lol? sorry for all the newb questions

to be perfectly honest. you need to do some more research into your project. there is a lot of catch 22's with the lsj that people over look a lot
