Hey everyone,

I'm clueless when it comes to most of this stuff.

Just wondering whether this is a 'good' turbo for it's price:

http://justjap.com/store/product.php?productid=16693&cat=294&page=1

Also wondering if anyone has had any experience with this product too.

Looking to replace my stock turbo and was linked this kit.

Thanks.

The GTRS is a great turbo, and designed specifically as a bolt on skyline kit, but it is three times the price of an equivalent Hypergear swap. Even an externally gated Garrett and custom fabricated exhaust/intake would probably cost less.

^^ what they said.

Remember that if you car is stock (or mostly stock) then its not as simple as 'just upgrade the turbo'.

You may need a number of supporting mods to be able to run it smoothly.

Its all in these forums so practice using the search function,, A LOT! =)

Cheers for the replies.

I read a few pages into this section of the forums and discovered that a lot of them were created years ago haha.

Therefore I assumed that searching for old threads would be semi-pointless due to outdated information, etc.

Also from what I know, all I need is a bigger fuel pump and I'm good to go.

If anyone is able to show me a similar or equivalent turbo which scotty nm35 mentioned, it would be greatly appreciated.

As I said, I'm a noob when it comes to most of this stuff haha.

Read the rb25 dynov results thread. start at the end

Will do.

And then join the hypergear revolution lol

Well if it's as good as everyone's saying it is haha.

You will need an ECU, fuel pump, injectors, intercooler and tune with any turbo you choose in that HP range.

Got everything except the bigger fuel pump then the tune afterwards.

Also, better off buying HKS turbos from Nengun/Greenline/etc because it ends up being a bit cheaper

Just Jap is great for most things, but found the price of the HKS turbos a bit much

I'll definitely check Nengun.

Thanks for all the responses.

Really do appreciate it.

Hypergears new highflows would outperform the GTRS, way cheaper too. Spend left over cash on Injectors and pump and convert to E85 :P

Not to start an arguement with you, but please justify what you mean in terms of out perform?

Are you meaning straight out power figure? Dyno king

Power curve will build sooner?

Torque builds faster?

Boost to power level, meaning same boost and engine stress?

Street driveable to track?

I only say this as i dont like statements that simply say 'out perfrom' or 'better' without any imperical evidence as it can mis-lead people into making a choice that might not suit what they are chasing.

Similar to people chasing power figures rather than a target of driving experience.

This is by no means me suggesting HKS or Hypergear, i say each person is different with different goals in mind, so find your end goal and build to that with price as a secondary option.

Hence why he said it was better as a blanket statement.

Again i see an opinion and no imperical data of back to back tests or 2 dyno charts to prove this with all other factors being equal.

Do you have any charts to prove the curves do build quicker, more boost at same RPM, more power at same boost?

To clarify i dont have any that prove this wrong either.

I am an engineer so like to see evidence of what people claim, as i can claim anything i want as long as i dont need to prove it.

You should check out the hypergear thread, there are more dyno graphs than there are sheets of perforated toilet paper on a roll.

And yes a SS1PU Hypergear will out perform a HKS2535, I dare say even a GT-RS

OP: If your dead set on a HKS turbo kit. I have a HKS GT2835 KAI kit for sale. I'm just using the intake for another 2 weeks or so. PM me if your interested. I've gone a Hypergear, but only because I wanted more power. If your only after 250-260rwkw then the 2835KAI is pretty spot on for this

Never had my eyes firmly set on the kit, just curious about more info about it haha.

Does look like I'll be getting a Hypergear, just time to choose which one is best, as from what I've seen on their site they're around $900-$1200 too which is awesome.

Cheers though.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
