allright guys and gals, based on my sig what should my next mod be.....p&p the heads or nos? i have a mildly modded bull and am looking to blow about $700 or$800 on my next mod. i am leaning towards the heads but, i don't have anyone around here that can tackle the job for me. i do think i have the mechanical knowhow to install nos, provided i have instructions. also, i can't keep the car down for more than the weekend...its my daily driver. thanks in advance, brian

I agree with the heads. But if you go for NOS, dont do what that guy did where he drilled a hole in his gas tank for it. LOL. :blink:

N2O would definitely be do-able in a weekend and within your budget, BUT I think you'd have to either pull your jet chip or have it reprogrammed. P&P'ed heads is within your budget, but will probably take more than a weekend if you pay somebody to do it. You might be able to do it yourself in a weekend, though. Overall, I think you'd get the most power-per-dollar with the nitrous.

if you decide to go nos, you should P&P the heads first anyways. NOS is nice and all but unless you have worked your engine enough it wont make as much difference. P&P, balance your engine, buy some NGK iridium plugs, maybe step up to a better ignition system, get a better radiator. I cant stress enough the importance of doing everything else you can with that engine before strapping on the NOS. I did it with my ford escort, but I got kinda lazy on the mods cause I wanted to beat those LT1s now not later. new heads and intake manifold and I learned the value of quality machining. With a turbo and a chip my escort topped out at 145+ To bad some old guy totaled it. cause that car was so much easier to turbo than this god damn no room having sable. excuse me now while I go cry at the loss of my SuperScort.

N2O sucks man...get the P&P job. You'll be much happier in the end...while you're at it, port and polish the manifold, also...

I agree with this.

But as mentioned, it is KEY to get a chip programmed for nitrous. If you will not do this, then you must at least pull your current chip, which advances timing. For nitrous, you want timing retarded.

Alberto,

I'm curious how a chip can be programed for nitrous if nitrous is something that isn't used all the time? Is it programed to retard the timing only when the nitrous is used? If so how is it aware that the nitrous is currently being used or not. Just curious about this.

There are two ways to do this.

The first, and most common, is to get a multi-position chip. When running on spray, you flip a switch and it toggles to a different program. Our chip holds up to 4 programs, plus stock.

The second way, which we only do while tuningon the dyno and only on some cars, is to useteh IAT sensor to retard timing when the temperatures are significantly low, which would happen when spraying. This will only work on warm-climate states like Florida, thatnever say extemely low temperatures. Otherwise, your car would pull timing when in winter.

Ah great. Thanks for the info. Been wondering about that for a short while now but never thought to ask until you mentioned it.

thanks for all of the great feedback!! i have decided to get a set of heads from bob that he will p&p for me. i am currently developing the possibility of using a throttle body form a 4.6 mustang. i am getting a plate machined from aluminum to help piece my current upper plenum to the throttle body. it will bolt right up but, you cannot dremmel the area of the buttefly to allow for clearance issues like you could on an aluminum intake. the thought is that i have an aluminum plate that is just large enough to allow the butterfly to open all the way and i think i have the cable routing figured out. i will have to mount it upside down, compared to my current throttle body. the cables pull from the opposite direction and you have to adjust for that. does anyone know if i would need the computer re-flashed with the throttle body or would that be just for a new maf sensor. also, will my injectors flow enough for the additional air flowing in? brian
