what could i expect power increase from my99 uk turbo 218bhp standard after i have fitted a cat back scorpian system and a green cotten filter??? i wouldnt expect much but surely a bit?

 

5bhp

 

**** all ide say

 

ok ill take the 5 bhp lol will a walboro fuel pump on top of that help at all

 

no mate things like that will only help if 1. your pump is knackered. 2. you need the extra fuel flow after a map or bigger injectors/turbo

 

decatting it will release a fair few ponies though

 

nooooooooooooooooooo i must not get into the modding war again on this thread

 

I'm sure we've been over this before young man.

1- exhaust system (preferably de-cat but sports cat would be fine)
2- walbro/HRC 255 fuel pump
3- decent panel filter
4- remap by one of the known guys

Will see a healthy increase in power (maybe in the region of 280) but more importantly will dramatically transform the drivability.

If you want to help it a bit more then a bigger top mount intercooler won't hurt along with some fresh plugs and a good service..

Another thing worth thinking about, by adding modifications to a car without having the fueling etc adjusted (ie mapping) it can sometimes actually lose power. Now with just 218 bhp I should think your already struggling to keep up with modern traffic so the last thing you want to do is lose anymore ......lol.....

 

Save up and get it mapped, that's the best possible mod

 

The mods won't add anything to the car standard but once it's mapped it would help.

 

yeah i know we have been over this old man all those need doing before map though just wondering if it will malke a difference before map or it will dmage car????

 

Here's the best bit of advice you'll get.

Buy all the bolt on goodies you want and store them away in your garage/shed/bedroom or wherever else you keep stuff. Take your time, save up and buy the best bits you can as rushing and buying cheap crap will be a mistake.
When you've got all the bits you want you'll need to save some £££ again, this time for the mapping. It's expensive but worth every penny. Once you've saved enough then call one of the many experienced mappers and book a date.
A couple of days before your mapping date you can bolt on all your goodies.
Get the car mapped and enjoy your new car.

 

 

Everything you need to know OP

 

thanks people looks rather pricey my friend has just broken his scooby and donated me a hand made cat back stainless for NOTHING in good condition too so downpipe now needed its a 2.5 inch centre section so take it i need a 2.5 downpipe cos ive seen loads on 3 inch advertised

 

3" will be fine as long as it tapers down to 2.5".
