New turbo, what else do i need?

**AaronB9006** · 09-08-2016,09:37 PM

Fair enough, also, my turbo makes a whizzing noise as i go through the gears, does this just mean its being stretched? (happend more after remap)

Could the extra load on older bearings on the turbo - could be un-related, depends what the map is doing. Is it delivering extra pressure or just fueling? Could just be a wearing out turbo, scored turbine etc.

I'm just curious, but define "intake" upgrade? Pre-turbo... Post turbo? Im not all that familiar with golf layout as I drive a b5.5 Passat but VW did a pretty decent job of setting up the air intake on it... Maybe the golf is different... I know people that stick cone filters on passats etc and it's a waste of time.... Just makes the intercooler less efficient as it draws air from a hot engine bay instead of a forced feed from the grille... Maybe I'm off on a tangent. Who knows... The hour is late and the eyelids heavy... Lol.

Yeah, ive done some research and a cone filter is what im looking at, looks like it does little to **** all in terms of performance, especially for the cost 1-200 squids, might give that one a miss..

A better flowing / larger intercooler, throttle bod, manifolds etc is what I would be thinking for a turbo. But the turbo will be doing the most work so probably a better inter-cooler, especially if its an uprated turbo with higher pressures. But you have to be pretty serious and on a plan to do all that work - depends if the rest can hold up to the wound up pressures also. Although for a diesel the butterfly is to stop it running away with itself.. so not sure on that one!

Im a serious guy, ive got the money, and the tools. Will let my mechanic mate at local VW do my turbo, but is an intercooler upgrade something i can delve into?

**SammoVWT** · 09-08-2016,11:29 PM

Yeah, should be straight forward to fit too, if you are going to get it mapped out

**AaronB9006** · 09-08-2016,11:31 PM

Cool, and in terms of remapping. Is it worth me buying a blue fin, as opposed to taking it to my local ECU place costing £200 each time, so i can just programme my car after i mod it, or is ECU remapping after mods much more complicated requiring a Dyno?

Personally, if I was gonna do all that work I would probably buy another engine and rebuild it from bottom up. Big end bearings etc. Start with a fresh canvass then and no nasty surprises. Second engines are cheap enough on the bay usually (engine code dependant obviously). Once built how I wanted, I would simply swap it into the car.. Cone filters on tdis are a waste of time IMO. You've got a turbo to force air into the engine... It's not gonna run out of air any more than we are. Colder the better though, intercooler is easy enough, have a look on dark side developments for a kit.

Cheers pal, and yeah, im just getting into the whole car mod game after buying a car thats worth modding for the crack, i think an engine rebuild is something ill look at near christmas time, when i know the car inside out, so i can build it to my spec. Also gotta consider insurance, sitting at 1400 in my dads name with declaring exhaust mod and alloys.
