This is an awesome turbo setup at a very good price! I know when I bought my turbo, the RRP was near 4.5 - 5k from HKS Australia (BD4s)!!!

Don't forget it's a HKS unit not a Garret, which makes this turbo even better. Whoever buys this will not be disappointed, good luck with the sale!!!

Free bump

HKS Rate this turbo at 480 Hp @ 14psi. I have a different opinion but thats another story.

Yeah it should be sooner on a RB20 or 25

infact there is a guy on here that has posted graphs on his car

but he is using the smaller, internal wastegated HKS 2835 PRO.

Lots of area under the graph...

MattR, hope you have a good supply of gearboxes:)

I have one, fitted to RB25 with a 0.61 turbine housing 1bar at around 3000rpm, it was like a switch. I now have 0.87 housing and have 1.2bar at pretty close to 4200rpm. Great turbo for SR20 or RB25, maybe a tad big for RB20, but I suppose that depends on what you like.

ed, SR20 has more torque than RB25 - so you cant assume too much there:)

If anyone is after a turbo for an easy 300rwkw, with good response, this is your baby.

Will it be able to fit on a GTI-R or is there not enough room up front?? im looking at getting a GTI-R and have a turbs like this on if it will fit

I would think that it would fit.

It is 20 cm long and 18cm in diameter.

HKS seem to make turbo's physically smaller then others

but with a high power rating.

If you buy one of those cheap manifolds from Ebay and modify it with a wastegate

you should be OK.

What I would do in your case is buy one of these $400 manifolds, run a 2'' adaptor with GT25 flanges that go straight up. Then weld a wastegate pipe into it to suit. I think this would be neater then to mod the wastegate into the exsisting pipework.

Then it is just a matter of heat sheild, new dump pipe, etc.

The good thing about doing it this way is:-

1 You can high mount it and run a decent size exhaust dump pipe.

2 You don't have to be an expert to do this yourself.

3 selling it at a later date would mean that you can unbolt the whole kit.

4 No major modification cost.

I would not worry about the gearbox thing unless you plan to abuse it...

Steve, one thing is that the RB motors may not have as much peak torque, but they sure have it a lot earlier then the SR20.

It is because of this they will come on boost earlier compared to teh SR20. Everything is a rapid succession after each other. Just like a well designed FMIC will bring on boost earlier due to the denser intake temp, providing better combustion, faster meaning more power earlier.

I think a lot of people fail to realise that and with this day and age of budget kits like the Hybrid IC kits, more and more people will not realise this.

What sort of Grunt are you making?

Yep, hybrid cooler (outlet sayed icy even on the dyno during tuning - so its not too bad)

I made 270 at 1.1 bar, 285 at 1.2bar but after that it started choking with a legal exhaust (enrico can tell you how quiet it was), peak was 309 at 1.7bar. I have since fitted a new exhaust, and now she pulls even harder - I love these turbos - absolutely killer.

EDIT: cant wait for a redyno, feels stonger than 309 now:)

    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
    • Welcome mate. Any pics? Even with a DE I'd be well happy if I had that as a 1st car.
