Bolt on HKS turbo kit for RB20/25 FS

[Guest justengt4]

As the subject suggests i have a HKS kit for sale. Uses a HKS tubular (but cast for strength) manifold with HKS external wastegate. Garret TO4E turbo with 0.6 comp and big turbine. Kit is pretty much as new. Turbo just come back from a Garrett dealer with a thumbs up and the whole things has been cleaned and bead blasted (looks like new). Pic attached and plenty more on request. email me on [email protected]

That was clever, forgot the price duh.

Asking $2000..... bargain

[rob77]

Any idea of how much HP it will flow?

[Guest justengt4]

Rob, good for between 400-500hp depndant upon boost. The 57 trim TO4E wheel has a wide efficiency island so you can run it hard or easy and still get good figures from it.

BOA2ME, Yup the turbine is fairly large, set up for top end drags. No prbs getting a smaller a/r turbine though, TO4's are pretty common. Comp wheel is pretty standard size for 400+, i have similar on my 3SGTE (2 litre 4 cyl)

what rmp would this thing spoolup on an rb25det. looks mad.

and with an external wastegate, and manifold, $2000 seems an awesome price.

[Guest justengt4]

Thanks DABIGBOLF (?),

It is an awesome price. I've just bought a house and need every dollar i can scrape together, hence this an many other very nice bits i had stashed away for a rainy day have to go asap. Just the HKS wastegate goes for nearly a grand so yes it's cheap.... but good

This thing is laggy in it's current form as it's set up for drags. With an electronic boost controller (Power FC). Full boost (1.3 bar) came on around 5000rpm. There was usable boost below that but the full boost hit was pretty hard. For drags and burnouts and general hoon fun this is a great setup. For strong mid range i'd advise finding a smaller a/r turbine.

Hi justengt4, was that on an RB20DET?

[Guest INASNT]

damn i would love this turbo but full boost by 5000rpm? damn to high in the rev range for me:(

[adam 32]

ive got one of these on my car and just downsized the exhaust wheel from a 2.24" to a 2" to increase driveability. cost me $340 for wheel and shaft - full boost by 3800rpm (1bar)

[Guest justengt4]

This setup was on an RB25DET. Yup, as i've said it is currently laggy but gives awesome top end. To get better response it's just a matter of changing housings, you wouldn't need to change the shaft and turbine wheel, it's just the current large a/r. Exchanging the housing would set you back maybe $200 depending on where you could source it. If anyone is serious about a purchase i'm happy to help them source a new housing if they want one.

At this price you're practically getting the turbo for free, a coupla hundred bucks invested in a smaller housing shouldn't be much of an issue?

[Guest justengt4]

I just got off the phone to Bill at ATS in Adelaide (turbo guru) and he gave me some interesting advice. While a smaller housing is optimum he said that just blocking off one of the twin entry ports with a thin sandwich plate is a surprisingly effective way of achieving the same result (faster spool up). I commented that it sounded a bit agricultural and he agreed but said you'd be surprised how effective it was. I guess it's like log manifolds, a bit dodgy but work 90% as well as a full equal length systems. Anyways, i thought that could be a could intermediate measure for anyone interested while they waited for the right size turbine housing to turn up. Changing the housings over at a later date wouldn't involve any extra fabrication as all the mounting points are identical. Food for thought.

I got a standard (i think) t04E on my RB25DET.

it's got a A/R 60 on the comp cover.

it hits full boost about 4300 - 4500.

on the RB20... the turbo i have spools around 5300.

But again the exhaust end of things can be modified to suit.

The car made 190 Rwkw on 9 PSI at 6,600 RPM

Car is super driveable and economical if your just crusing along.

And heaps of room for improvement with only 9psi making that power.

Got damn it hits hard... would recomend this for a serious upgrade for RB25's.

$2000 g's is mighty cheap too..

*free plug from my own enjoyable expiriance*

[Guest justengt4]

Thanks Nismoid, Yup boost did hit hard. Lots of advice to buy but no takers ? :-)

[R31Nismoid]

Ohh.. yeah, boost hits hard and hold solid.

just fry's tyres in 1st on 9psi at about 5500... and that's just from a dead standard launch and just putting foot to floor...

on 15 psi i'd guess 1st/2nd/3rd no worries

What 1/4 time did you pull if that RB25 was in a Sky... ? (on a side note)

[Guest justengt4]

The car never made it to the track (officially), was never registered actually. Did have quite a bit of illicit fun in it though. G-tech gave consistent sub 13's (all over the 12's) but we never the had tyre/suspension setup even close to sorted. Hmmm wheelspin, pretty much in any gear if you wanted it :-)

[sycorb]

can u tell me what size waste gate and will u sell with out waste gate ,how much cost

[rob77]

I agree this is an excellent price. I would buy it now and change the housing to suit so I could get full boost around 3500-3800rpm, but I wont be looking for a turbo for about 9 months. Still plenty of mods for me to do to prepare my car for the turbo Shame, as I've been looking at new garrett turbo's with an internal wastegate with a t3 flange so they bolt onto the stock manifold for around the same dosh as this one which has external wastegate and manifold. Great price, wish it was 9 months down the track unless I win lotto this weekend

[MrMayhem]

if sycorb wants teh snail and teh manifold alone id be interested in teh gate

[Guest justengt4]

Sycorb, from memory it's a 35mm gate but i'd have to double check. Dropping the gate... i guess $1700 for the rest

MrMayhem $350 for the gate. That's the beauty of buying it as a package eh :-p Maybe you and sycorb should get together

[Zila33]

Is the Turbo still for sale????

If so i will take just the turbo byitself pls let me know either way. thanks.
