HKS 3037 tuning results

[Guest INASNT]

y u got that other pipe branching off the intake pipe?

[Steve]

JasonO, apart from the manifold itself, I also had to have the aircon oulet modded so it didnt interfere with the manifold, and the power steer res moved so the turbo fitted

Pretty sure you dont have these probs with the HKS kit manifold. Mine is tuned lenght, but I think it would be better to go 3-2-1 as the japs do, that is, if you were making your own.

[Steve]

INASNT, that is the BOV return.

[B-Man]

Nice steve ! ! ! Your turbo sits heaps more forward than mine hey ?

Geraldjohn - Q45 - but is disconnected now.....

[JasonO]

Good news guys, I placed my order for the HKS GT3037 Special Turbine Kit yesterday morning :uh-huh:

Steve,

Looks sweet, thanks for the photos, you know they've saved you from having to answer a gazillion questions from me

B-Man,

Gotta love that shiny look, which exhaust manifold have you used ?

[Guest INASNT]

Steve

another question about your setup.

Why have u got a feed point just before the turbo from the catch can?

[Cubes]

JasonO,

Where did you order from?

[JasonO]

Joel,

From Sumo Power in the UK

[Steg33]

Hey Steve, just wondering what you're using the small catchcan to the left of your radiator for. I know the one at the rear is oil, but the front one?

I'm going to have a upgrade next week and will end up with a spare. Would be good if i could put it to use.

[RS500]

INASNT,

that's the breather hose from the catch-can to re-circulate the ventilated gases.

legally and environmentally, that's the proper way to do it rather than veinting it out to the atmosphere.

[Steve]

JasonO, good luck, I am sure you will be happy with it.

Steg33, that is actually the radiator overflow. With the trust plenum you have to remove the stock washer bottle, so I converted the stock radiator overflow to a washer bottle, then fitted the overflow can. Sligthly different to a catch can, as it feeds from the bottom and has a vent at the top.

[Sydneykid]

Hi Steve, when you changed from the standard RB25 inlet system you lost the cooling system bleed valve on the top in the plenum. Is there some other way that you get the trapped air out of the engine now?

[Steve]

i have no idea, perhaps one of the many others running trust plenums could enlighten you? (B-Man, what did you do with the cooling system bleed valve?)

what is a cooling system bleed valve?

how often do you need to bleed air out of the cooling system?

how does it get trapped in the engine?

why doesnt coolant displace it?

does the engine get vapour locks?

how long does it take before this becomes a problem?

how do GTRs get around this?

do they have a cooling system bleed valve?

why doesnt the cooling system get bled when the car is serviced if it is an issue?

cheers

[B-Man]

nfi - but i will ask the question.......

I did that temp on mine awhile back but when u pull the hose off the intake u get oily residue all over the intake.

[Clint32]

i thought the rb25 plenum had it in a pipe seperate to the manifold so it could be used, unlike the rb20

[Steve]

INASNT, yes you do get an oily residue, you need to have baffles in the can, or some medium to remove the oil particulates from the vapour. Works alot better that way.

[Guest INASNT]

Even with baffles u get a bit of shit going back in dont ya?

[Steve]

unfortuneately - its a matter of legality, not that you can do anything but very basic mods here in SA without it being illegal.

I hope to be going over to NSW to get it legal, one day.

[geno8r]

Thats a fair bit of extra piping just to vent the BOV back into the turbo compressor.

If you dont want an atmos BOV, why wouldnt you get a plum back?

Whats the benefits of your crazy piping, i've never seen that before.
