My car has a v8 in it but used to have only 175kw which is pretty s**t but now i did some mods
3 inch exhaust 4-1 Extractors , high flow cats Cold Air Intake K & N Air Filter Stage 2 Adjustable Shift Kit Monroe gt suspension superlow Kings springs how much kw does all those mods add up to and whats the next best upgrade to do on it to get it to 220kw |

the 175/185kw has std gt40p heads, single valve springs, std rockers, 9.0:1 compression, 65mm throttle body std cam.
the 220kw has gt40p heads, larger valves, double valve springs, tella terra roller rockers, 9.4:1 compression ,port matched manifold, 70mm throttle body and different cam. given that you have headers, high flow cats and 3" exhaust and cold air intake you might have gained 15-20 kw.. the rest of the mods don't really add to the cars power out put.. |

not much more you could do with that amount of money..
other things like cam. head work . j3 tuning will cost more than $350. you could get msd coils to add a slight improvement.. but it wont be much, lucky if 1kw would be gained imo.. |

if irsquote="Capative Pit"]how much would it be to install a ts50 wing or lower it on ulralow spring(i have the springs) rear only[/quote]
thats open to debate.. also depending on if you already have the wing and wether or not it needs painting.. most panel shops would paint and fit a wing for around $200. to fit the rear springs depends on wether it has irs or live axle. could cost anywhere from $70 to 150... if you like playing with cars you could do the rear springs your self. If irs you will need a spring compressor.. |

Underdrive pulleys can be found cheap.

From reading up on V8 mods, a lot of guys in the US say the Ford springs are not good enough when the hp is increased. I've just bought a set of the Crane beehive springs for the GT40P heads for a bit over $200 (as I can't afford a few grand for aluminium heads at present). If you're going for an aggressive cam later on, you'll probably need double valve springs.

Au v8's are very very slightly underdriven from factory so much so that i wouldnt consider them under driven at all.
If some one made a set for the au id have bought them, i believe what stops everyone is the crank pulley has the encoder wheel attached to it. Underdriven au pulleys from factory... myth busted... |
