wrx turbo

[Guest]

i need a little advice on what sort of turbo i should run on my wrx its running a 06 2.5 block atm with 800cc injectors top feed fuel rails and a link g4 tdo5 20g witch made 200kw atw at 12psi but i want more power LOL i was sort of aming for 400hp maybe LOL

any ideas ?

[Koom]

How about an HX40 Holset?

Google Image Search Mines smaller than the 40. My 2.0L would never get it to spool up.

200kw atw is still pretty safe for that at 12psi. I got at 21psi 221kw atw with my td05/18g and that was limited due to fuelling issues and that was on R.E sinclairs rolling road dyno.

Turbo's though, hmm heaps of offers. Personally Im looking at a garrett 3076 however if I can get a td05/06 hybrid for a good enough deal I may go down that road, but so far cost wise it's almost better to go down the garrett road.

Holsets that Koom mentioned is another great option, very good price and built reliable. It's an option im certainly watching

a 3076... ehh.. why that big? interesting choice, watch this space for my tune results.

Seen it done many time before, it's a known combination on the track that works very well.

fwiw

12psi on a 2.5 is pretty close to 18psi on a 2.0 engine

Bit of a supporter of Holset eh Koom

Na I just like to encourage stupidity along the same lines as what I've previously convinced myself of...

Ever seen a KKK on an EJ?

No I haven't actually. Seen the odd Borg-Warner/Schwitzer on one or two down here though. As with the Holsets though, there's a myriad of options to choose from at your peril.

12psi on 2.5 is close to 18psi... Ok me lost lol would you be able to elaborate on that as I never realised it made a difference between 2.0 - 2.5. Always thought u could just put more boost through the turbo or has it something to do with greater amounts of air being pulled through due to it being a 2.5 or something hence limiting what boost u can goto?

yeah dont you know that if you want a true boost reading, you have to order the special 2.5l boost guage! A 2.0 guage wont tell you the truth...

He's talking about air flow. i.e. a 2.0L @18psi will have equivalent cfm to a 2.5L @12psi. And airflow equates to horsepower.

So, a 2.5L @ 12psi will make about the same power as a 2.0L @18psi. All else being equal.

[Guest]

yep thats what i was talking about.

12psi on a larger engine is alot more flow - so altho it sounds low if your use to 2.0 boost levels it may not be on a 2.5.

[funkytown]

question, coz i don't know.

isnt the nominal flow just the same? but relative to the boost pressure its more?

Are you asking something along the lines of this;

2.0L @18psi will have equivalent cfm (volume flow rate) to a 2.5L @12psi [at the same rpm points]

[Guest]

Its more what ?

Yes the airflow is the same.

A compressor can make the same flow at different pressure ratios.

Sweet gotcha
