-Pi heads that are ported, milled and valve job on the seats. Leave the swirl dams alone!
-Pi plastic intake.
-balance the piss out of your rotating assembly.
-Not bigger but tighter lsa cams then stock. You dont need the biggest cam a 2v can withstand.
-upgraded springs.
-flat top pistons for higher compression. 12.x compression is a even start for 93 octane. E85 and meth will allow you to use higher compression. 13.x and so.
-long tubes.... Not really a best longtube needed neither. Mac is decently priced and works.

Ntk o2 sensors are most accurate.
Ngk tr6 plugs are notably worth while...

This is not a bible but known to work.

essentially what i have, let me share my experiences with you.

Without a tune and everything he just said my car would rape alot of stuff that i had no idea coming close to.. 3v/c5 vettes/srt8 anything/turbo 4cyls etc.

now before everyone jumps this let me first say that being a honest person i will say i've lost my fair share too and know exactly what its capable of and not.

i know this doesnt answer your question because you requested a horsepower # not a gain.

A gain to me is raping someone with a "hundred more Whp" or howmuchever i know there is a +- Variable depending on the car you're racing.

Thats why when people ask me what my car makes to the wheels i always say i dont give a shit what it makes BUT heres what it can do.

i'm not against this thread in any way having built the exact same thing and loving the shit out of it every day and will forever. I just wanted to throw a curveball into this and draw a different satisfaction that you're overlooking

Good luck with your build bro and feel free to pm me with any questions, because like i said I've done it 3 times. once with my car (three motors) and two friends NPI cars too.

If you are doing the install and are going with an off the shelf cheap long tube then yes. If going expensive long tube then no.

Unless you are loaded. As long as you take care of them headers are generally pretty easy to resell so you could recoupe some of what you spend. "Some"

philly101 · Oct 13, 2012

So just go with shortys then lol

Willis_98GT · Oct 13, 2012

most short tube headers can be adapted to turbo kits too so thats another thing you can scratch off the list when you start putting parts together.

This is very true.

What turbo kits were you looking at?

philly101 · Oct 13, 2012

I was lookin at the on 3 an another one can't think of the name right now. Any one kno why my Sig is so big by an chance

foofinator · Oct 13, 2012

Boost.

philly101 · Oct 13, 2012

What are some good shorty headers

vermilion · Oct 13, 2012

-low to mid supercharging: you can use a 10.5 boost. IE basic P.i swap.
-high supercharging: 9.0 - 9.6. compression ratio. 99^ engine forged
-low to mid turbo: 9.6. the turbo will spool rather quick. 99^ engine
-high turbo: 8.x compression. forged custom.

E85 allows more boost ranges on higher compression. its cooler then fuel. it allows slightly more timing.
again this is not a bible but it works.

BigBore96 · Oct 13, 2012

I like on3. Couple local guys have their kits and have had good success with them.

Your sig is big because you need to shrink it.

philly101 · Oct 13, 2012

I think I'm goin to get the on 3 since its the cheep an I can put my money to the tune

BigBore96 · Oct 13, 2012

Just be ready wth any major addition to the car, adjustments will have to be made.

philly101 · Oct 14, 2012

What would toyA say be major upgrade

BigBore96 · Oct 14, 2012

Any type of forced induction. Any motor build, etc

Basically was just saying that anytime you do anything, something comes up and it is'nt as smooth as it should be.

philly101 · Oct 14, 2012

Well this will be my 1st piston eng build.I always had to rebuild my rotary eng every 2 years

philly101 · Oct 17, 2012

Dose any one kno if you have to use the kmember on3 has or can you use a diff one

BigBore96 · Oct 17, 2012

You should be able to use just about any tubular without issues. They generally all are the same. I believe they use a QA1.

A MM or Griggs one probably would cause issues with fitment.
