Switch to a twin turbo.

Just kidding.
Smaller pulley, fuel system upgrades, better engine management. There are a few guys on the forums that made high power on built motors.
If you want something low budget and about 400whp, contact a member named LiNkS and ask him.

 

i was confused between the aps single turbo kit and vortech.
but i ordered the Sc P
i'll contact links ! 10x man

 

I'd first install a quality set of headers like strup, DC, nismo, crawford. If you still want more power, new pully and UtEC, if you still want more, JWT cams, and then if u want more, built engine w/ Ttrim blower +bigger IC + bigger injectors

 

should i replace stock pistons?

 

won't do much. if you want real power like 500+ i say you contact someone on the boards by the name "Booger". I believe he has a built motor, T trim blower as wellas a bigger i/c. hes up there in the HP range.
You can also swap to a 3.9 FD which will give you a 10% boost in acceleration (not power)

 

Headers and breathing mods are the first thing I would do . Then you can go to a smaller pulley [ 3.12 ] will add around 25whp . The [2.78] pulley will get you another 25whp . Some claim much more than that . The 3.12 pulley can be run safely on the stock kit . But when you go to the 2.87 , it can be run on the fuel system , but I would think about going with a upgraded fuel system . And lastly , you can go to a different EMU for more control of the timing and fuel to gain a few more WHP

 

im running 400 wheep hp at just under 8 psi. Mods are vortech with 3.12 pulley, dc sport headers, test pipes and borla td exhaust, tuned by cpracing. i guess i had some belt slipping when the new pulley was put on or something but now im hitting between 9 and 9.5 psi. I havent re-dynoed but hoping to very soon. one day i'll jump down to the 2.87 and also a nice return fuel system. I would honestly like to get just under 500 hp but i know i'll need a few more mods. Plenum being one of those, cam's wouldnt hurt as well.

 

XAV, all u need are headers, test pipes, and a plenum spacer or the intake plenum itself, then if u want more gains, go for JWT cams. This is what i have done. I hit around 400 whp with stock boost

 

alshawi,mabrook that you hit 400whp,any dyno picture you have and did you upgrade your VB,TC?

 

thanks blackend, its actually just a bit more than 400, and i have ordered a new tranny from the dealer so i can send it and the ecu to forged internals, it should be in bahrain by 2 weeks.

 

did you dyno the car?what max psi you reach with over 400whp?cause same your mod we done alot of them but never hit over 400whp,did you use the tuner kit?it is amazing that you hit as you say more than 400whp,what is your tq?

did you order new VB?or the hole tranny and how much it cost you,,,at least post your dyno

 

i guess i m gonna order headers , cams , brake rotors soon.
u guys recommend any dealers out there?
i ordered the parts from mynismo.com , but they still have their site down...

and 10x for the advices !

 

If you want some good headers I would look at the Crawfords. He just came down on the price too.

 

post 666 at that

 

i have the HKS Dual Hi-Power Ti Exhaust on my z , which headers will best fit????

 

I know there's been debates here on headers before but I can't remember who with ... from what I understand (not speaking from experience) is that headers will only gain you 2 - 3% gain hp for a very high cost. Just my $.02

 

Headers will only get you a little (if anything) on an NA car, but once you go Supercharged... "you're gonna want those headers"
- Bruce Dickinson

I would definilty recommend going with JWT cams. I they'll get you a pretty substantial gain w/out having to run more boost. That was the route I took. Praying for a stock motor that will last me a long time, be problem free, and smog legal.

 

i agree with dimebagdolf, people with sc's make a lot of power with cams and headers
