Turbo Options

[muzziak]

Hey guys, I've got a KLS power spirit turbo A/R .63 running around 15 psi at the moment. I was thinking of getting a new turbo but I've been reading lately that they're actually not too bad and can handle 350-450 hp range and should provide 230.5kW at 12psi. I've got all the other usual mods, ecu, splitfire, fmic, turbo back etc etc. was just wondering if it's worth upgrading to a garrett 3706 or kinugawa tdo6 or just keep this turbo and work top end. Thanks in advance for any advance

No need to be snide, im somewhat new to the whole car scene. Well the cars a daily, so I'd like a bit of extra power but responsiveness as well. Budget around a G or little more, the lower the better. And meant 3076R

[muzziak]

Well that's what I'm confused about, I've read a lot of different varying opinions on the KLS, some say it's shit, some say it's not bad, so I'm not sure

[GTSBoy]

Well, the thing that interested me was the precision of the estimate of how much power the KLS should make at 12 psi. I mean, quoting power to 1 decimal place shows a lot of confidence.

But, apart from us being snide, you haven't told us what engine. 20, 25, 26, 30? Or something else? Also, no mention of if the power levels you're talking about are at the flywheel or on the road. We can guess, but we could just as easily be wrong.

And I think you can take it for granted that with very few exceptions, eBay turbos like the KLS thingo (I can't help hearing

when I read that) are generally poorly matched not quite good turbos.

I suggest that you look for the Hypergear thread for some guidance on what can be done in the $1k region.

[hypergear]

For 1K. I can supply you a high flowed Rb25det turbocharger. It will beat your KLS unit in Power, Response and Longevity.

[Blackkers]

^ Do what this man says.

21u highflow lowmount IWG is the best turbo for a daily

[75coupe]

1k min for turbo, plus tune plus other bits and pieces, and there will be bits and pieces along the way, so budget 2.5k

[muzziak]

Thanks GTSBoy, it's a 25det and had dyno paper at 220Kw in 2013, lost the paper though. Well that's the worry, who knows how credible their information is,thought I would ask. So as a starting point, would you recommend me changing the turbo or working top end, eg injectors, cams etc. and what would make the most difference performance wise ?

[GTSBoy]

Short version......never "work the top end" unless you are on a full out build.

Shorter version. How much power are you actually after? Usage model?

[muzziak]

I want to get around the 250kW range atm, so bump it up 20-30kW. Would a turbo upgrade provide that or should I do something else

Grab a beer, start from page one.

[75coupe]

Hmmm only want 20-30kw ...

First time huh, cute!

[muzziak]

lol initially from the next upgrade yeah hopefully. More later on
