Hey how do you guys pass smog with like 500 horsepower cars? If you put the mid pipe back on are you ok? Or do you have to retune your car with lower injectors and things to pass sniffer test? California smog is strict. Reason i ask is i blew engine I am gettin a longblock with ported heads...

I am having my longblock built and I can only afford stage2 ported heads or stage2 cams. Car is going to be a blower application, so what do you guys think I should go with? p.s. stage2 cams idle would be awesome, but if ported heads have better gains, then those. Also Iam in california so...

I cant decide between a vortech mongoose kit or a Kenne bell. 400hp for now until i get a shortblock. In the end I want around 5 to 600 rwhp for my STREET car. I figure kenne bell with nitrous would make this. My mods are 3;90 gears, exhaust, 75mm throttle body and plenum.

I am one of the unlucky few who just installed a 75mm throttle body and plenum from accufab and my idle is off. My idle is at about 1200 and i rev and it hangs at 2000 for a sec and drops back down to 1200. How do i adjust my idle speed to get it back below 1000 rpm. 2002 mustang gt. only have...

Can I use a 75 mm throttle body and plenum with the KB and I have 3;90 gears too much for KB? Is there anything else I need besides spark plugs with the KB intercooled 1.7?

I have an order for a Vortech v1 s trim head unti supercharger and abase kit. Is there anything else I need for the install like vortech electronics or can a shop tune it without vortechs electronics?

Iam looking at a v1 s trim head unit for my 02 gt and the seller says its counter clockwise rotation, for my application does clockwise or counterclockwise rotation matter as well as straight or curved discharge?

Ok I origionally wanted a mongoose kit vortech sq. But I cant save 3 grand i end up buying other car parts. So If I buy the head unit from vortech for 2 grand. And then I buy the Base Kit from vortech(all the tubing and crap). Is that a complete kit minus the tune. And can I order a tune...

I want to get vt stage1 cams, and iam setting car up for a lot of power so I want to buy a rotating assembly from steeda so my internals are good (rotating assembly comes with forged pistons, cobra crank, gaskets, rods...) SHould I install cams and all that at the same time would this be cheaper?

I noticed sometimes when I turn off car i get out and walk to the back and a small line of smoke thin comes out of left tail pipe and then goes away after 10, 20 seconds tops. A problem> or dont worry about it?

I noticed on the freeway going about 75 in 5th gear in the upper right of my engine I hear a sort of squeak noise randomly almost like a mouse it happens randomly. Anyone have any ideas, only thing I can think of is exhaust leak at header and midpipe. I have off road x pipe steeda cat back.

Stock block 02 gt. If I get stage 2 vt cams, will it affect smog and what valvesprings should I get? And do I need anything else besides a tune?

Hey I found a vortech Sq kit non intercooled for 3000 and I was curious if i need to buy anything else for my car to keep the engine safe its gunna be a daily driver with the blower. Do i need fuel pumps spark plugs injecotrs? Or is the vortech kit complete?

Iam considering swapping out my mac o/r x for a bassani o/r x But will there be a sound difference at all? I doubt horsepower will change too.

When you buy 3:73 gears for a 02 gt after you install them do you have to set the speedometer? How and with what?

Whats the loudest / best Catted X pipe?

With the vortech mongoose kit, should I forge my internals first or will it still be safe daily driver. If i need to forge my internals what do you suggest I do to reinforce the engine? Any help would be great.

Are long tube headers smog legal and do I need shorty x pipe for long tube headers. Right now I have mac o r X pipe and steeda cat back Should I even bother with headers?
