Turbo upgrade MY05 GT

[KiDo_Tuning]

Yep. Stock injectors will be mint. I think you will run out of stock fuel pump at around 170kw at wheels.

On pump it's more like 220kw

Yeah nah.

We are talking about fuel pumps here. Mine flopped at high 170s...

Usually is due to injector duty tables Seen plenty run out of fuel with bigger injectors in this power region due to the fuel pump duty being on 66% on full boost.

Doesn't the stock pump only flow 155lph?
And isn't it only really good for 43.5psi + manifold pressure?
Mine ran out of pump with stock injectors and a vf34 running 18 psi. The worlds most expensive pump, the AVO drop in held on to about 265kw on e85.

I thought this too but have also seen a few WRX dudes run stock pump and E85 on their 52s with ID1000s. Same pump?

Better pump in the post-FL?

I just put a DW65C in mine because it ran perfectly fine in my Foz for ~220kW on E85 (ran out of turbo)

I've decided to grab a new fuel pump off JacksGTB just in case. They're relatively cheap anyway, so why not?

[kiahatsiu]

Good thinking.

Due to lack of income at the moment, I can no longer test out the Kinu 20T as hoped

I have stumbled across some helpful information though. I found a dyno plot of a guy in the UK running a JDM Spec B LGT with the (stock????? So he says) TD04HLA-19T. Seems over 300 bhp atw is achievable (he does have an STi8 bottom end; I'm guessing this is one of the "forged" EJ207s...)

Above is also a forum member on here: JMlegacy or something similar

[Sean82]

Ah OK
Thanks Mick

That's some pretty impressive power from a stock size twin scroll. Boost looks like it's on nice and early at ~3,000 RPM and holds relatively well.
Would be plenty of fun on the street I would think

I was under the impression that the stock TD04HLA-19T didn't like high boost very much?

I'd like to get around 200awkw out of my Manual Liberty wagon and assumed I'd have to take same route I did with my old GC8 WRX by upgrading the fuel pump to a Walbro 255lph, Turbosmart FPR, TD05-18G turbo and turbo back exhaust.

According to Kinugawa, their 19T outflows all the single scroll VF turbos (only by 10CFM though). The VF turbos can get an 08+ WRX or 04+ Foz XT to 200 without too many worries (auto sees about 20-25kW less)
So I would say the HLA-19T and -20T, getting 200 from the better EJ20X is very realistic...

[SHIZNT]

I can see it making decent power with the higher compression ratio netting a few extra kw but it would take a whole lot of boost being pumped though the relatively small TD04HLA-19T on pump fuel. Also the other question is how long would it last at high boost levels?

I would think a bigger turbo making the same power on lower boost would be a more reliable setup.

UK use BHP which is ENGINE power not WHP

Caught me out the first time I tuned an SR20 over there and it made 225 BHP from an NA 2L SR20VE.

[SHIZNT]

Makes sense, an VF34P18 on a EJ205 barely makes 260hp on pump fuel. Couldn't imagine a TD04 making that much hp at the wheels.

Update time:
Can now 100% confirm that the TD04HLA-20T from Kinu bolted onto my auto 05 GT Lib with no problems.
Had to use drain pipe from the old turbo (not the new one supplied) and another water line and everything else was spot on.
So basically, vf38 comes off and this one goes on except the stuff mentioned above.

Got a tune from Matt too and the car is much much nicer to drive and goes pretty well too.
Peak around 18-19psi falling back to 15psi at the higher rpm.

No dyno number yet or qtr mile mph yet but hoping to get something in the next month or two to confirm power.

In terms of speculating for now what power it puts out, based on standard sized injector duty cycle (92%) and another similar car (with an auto) that matt had tuned on a dyno recently its 'probably' around the 170-80kw atw mark...and it feels it too.... but again this is just speculation and will have to confirm most likely with a qtr mph number.
