20th February 2007, 18:08

20th February 2007, 18:10

becuase im gunna start moding my new vts soon and was just wondering what bhp increase im guna get for different mods

20th February 2007, 18:14

normally

induction, full system + 8-9 bhp
add a decat and manifold + 15 bhp
add cams and remap + 155-160 bhp
add bodies depending on cams 165-185
can go on

20th February 2007, 18:16

do u know aproximatly how much it would cost for cams n remap ??

20th February 2007, 18:19

buying and fitting them + map, looking at around 1k

20th February 2007, 18:21

would u have to get other mods done b4 that so it dunt cock the engine up ? cant u tell im a noob

20th February 2007, 18:24

no mate, cam belt change when change cams, thats about it. engine will be fine their bullet proof

20th February 2007, 18:40

sweet. what ypu done to your car? and what about ecu upgrade?

20th February 2007, 19:50

my car is induction, manifold, decated system, cams, head but not mapped.
you can map the standard ecu or buy standolone management (new ecu). that way you can add bodies after as you cant run them on standard ecu

20th February 2007, 21:48

how much u spent on it alltogether and whats ur current bhp

21st February 2007, 08:30

pretty spot on from bullit, each car is individual though

21st February 2007, 13:44

Yer I think its safe to say that most people will only take engine mods to the Induction kit, Exhaust Manifold, Decat and performance exhaust as them mods could see a healthy 130bhp-140bhp depending on the parts used ie quality and the engine as even standard engines can vary in performance.

The mods mention above could set you back anywhere between £300-£400 for budget items or upto £600-sky's the limit really thats why most people stop at these mods as they turn there attention towards suspension, wheels, interior and other mods which they feel the money could be better spent than further engine work.

Really it all depends on budget - Speed is simply a question of how much money you have :-)

21st February 2007, 16:26

well i dont wanna go crazy on the mods at first, im getting viper induction kit and a costom decat exaust from man bak with twin exits, got quoted around 3-400, any recomondations on the man??

21st February 2007, 16:28

If budget is a concern then people get good gains throughout the rev range with the raceland 4-2-1 manifold. Would complement those mods better than a 4-1 IMO

21st February 2007, 16:33

well i dnt reali wanna go cheap on it, one of my friends recomended a janspeed one, but im not reali all that good on what to buy lol.

22nd February 2007, 16:32

anyone else have any sugestions, i do have quite abit ov money to spend.

22nd February 2007, 17:29

i have around 140, spent around 2k.

if you want all out bhp i wouldnt have a viper as they have metal casing around them so heat up.

how much do you have to spend now?

22nd February 2007, 17:33

enclosed filter
decent manifold
decent exhaust

thats what i have and thatc ame to about £700 odd

depends how much you have

22nd February 2007, 19:15

i have about a grand to spend at mo, hopefully get exuast sytems and viper ind it outa it

22nd February 2007, 19:19

22nd February 2007, 19:28

Raceland mani and a 2nd hand BMC

22nd February 2007, 19:44

well im getting a custom made de-cat man back system with twin exits, a few ov my friends have had these with brill results, can get it sounding exactly as i want.. that will set me bak around 350- 400 then 240 for viper ind kit, gives me around 300 for a manafold?

23rd February 2007, 18:04

anyone got any ideas?

23rd February 2007, 18:19

custom exhausts are invarably loud and shit. Viper ind kit is average.

How about a decent exhaust, keep an eye out for a used BTB? and then maybe a good induction kit, say a BMC and then a GMC manifold?

And less of these pub figures please. Adding 10bhp here for cams and 5 bhp there for an exhaust won't help you. Being completely off the wall, finding out where improvements can be made and, here's the crazy bit, understanding what each component does will in fact get you a better car to drive. BHP figures are for the pub. Which is where I'll be as soon as I can get out of work

23rd February 2007, 18:27

was gonna mention zorst but ive said twice about the filter dave so gave up.

23rd February 2007, 18:33

if ya like get ya head skimmed to 2 mil you get an extra 2bhp from that alone dependin on mileage if it over 90isg it wont make a difference but otherwhiles it well worth doin !

yes. Great. I'm off to spend the day ripping the head off my car to skim it for the sake of two lame ponys

24th February 2007, 02:03

nah the place near me have had very good results with there custom exausts, and they get it exactly how u want it to sound, my friend is getting his done on his vtr tuesday so i will c the results, 350 for a man bak decat system with twin exits iant a bad price. he also has a viper induction kit so i will have to c what hes gianed

24th February 2007, 09:44

i know u really want that exhaust but peoples opinions are well worth listening to on here as a lot of them have been there tried that already. so u speaking to people who havea great deal of experience on this. just summit to think about before u buy things.

for example the viper. u need an induction kit which will resist heat as much as possible otherwise there is a possiblitly that u will actually lose bhp not gain it.

24th February 2007, 17:04

well whats the best recomended induction kit on the market at the moment, if moneys no object???
