Turbo's

Ok here goes for a really stupid question, on this webpage http://www.scoobymania.co.uk/performance_info.asp?c=4 they have turbo's for sale, i have a standard uk300 producing about 212bhp, if i bought the turbo here which quotes 340bhp, is it reallly as simple as removing the old one and replacing with the new turbo to give me 340bhp?

As you can tell im no mechanic

No

because you would need surrporting mods as well

reminds me of when i used to see ads in Fast Ford for 380BHP chips

i used to think fitting one of those would give me 380BHP on its own

You would need a lot of other mods like
FMIC, De-Cat Exhaust, Fuel Pump, Injectors and a Remap.

Oh and then to stop BIG BRAKES

A FMIC wouldnt be needed i woulda thought

a STI 8 TMIC with tray(imporant part that is) would be good enough

ok im a little lost now, so even if i chip, full exhaust and induction kit my car, i would hopefully like to see around 260-280bhp, so then if i bought that turbo would that then increase the bhp to over 300, would i have to get another remap?

Turbos are only efficient based on there size they will run within certain bhp limits dependant on their size and ability to flow air as you increase boost - take any given object air can pass through, at a certain pressure it will become inefficient due to it getting choked up(it will only flow so much based on the space/design) also producing more heat-not good at all, thats how i see it.The bigger the turbo the more lag or slower spool up at the bottom end hence the need for antilag on serious bhp cars.By the way mate it aint as easy as just picking a turbo-me mate with a pulsars found that out spent a grand on one only to find it came on boost about 1000rpm later than the std one-speak to a specialist first you dont wanna be suffering from overkill by putting on a larger turbo than u need.

anyone feel free to correct any of that but thats how i see it lol.

If you fitted a 340-350 bhp turbo It would have to be mapped to alow for the extra boost/air you will be using. You mapper will then tell you you do not have enough fuel getting to engine so 550 injectors should sort that out. Your mapper will then tell you the airbox is maxed out and induction kit is really requied. So on goes the induction kit. You will then find the MAF is right on the limits or even maxed out. So aftermarket ECU is required to do away with the MAF. It goes on and on. Untill you find 350 BHP is just not enough and you require more...
