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Therefore I assumed that searching for old threads would be semi-pointless due to outdated information, etc.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

    • So, before putting them in I need to understand the stock ride height. This is how I measured it: First, check the diameter of the wheel's centre cap, it was 52mm. Then put a piece of masking tape approximately across the centre and measure 27mm (half) from at least 3 sides to get a reasonable idea of the centre of the wheel cap. Mark that with a horizontal line as one measuring point. Then, directly above the wheel on the guard, put another piece of masking tape in approximately the centre. Use a string line to find out the point on the guard above the centre of the wheel cap and mark that. Then it is simple, just a tape measure to check the distance from centre of the wheel to the centre of the guard. Final results where  LF: 381mm RF: 379mm LR: 401mm RR: 400mm Pretty even considering they are 120,000klm old factory springs, lets call that 380 front and 400 rear.
    • So....knowing that I have a problem with power steering temps on track and another Wakefield day booked in next Friday, I've done the obvious thing They are very reasonably priced at $1650, considering they are a big monotube shock, double height adjustable (don't have to change pre-load to change ride height), one way adjustable damping and standard sized and customisable springs if you want something other than what comes with them. They come with 9kg/mm front and 4.5kg/mm front and I went with that as a starting point because I'll add adjustable sway bars too https://justjap.com/products/bc-racing-coilover-kit-ds-ds-infiniti-q50-v37-14-current#description Unfortunately they didn't come with rear strut tops so I've re-used the factory ones which was a bit of a pain. Also, the adjuster for the rear shock will be an absolute nightmare to get at, and while there are extensions in the kit I can't see any way you can actually attach or use them
    • I also had 2 bulbs blow at once, years ago in the stagea. made for a fun drive home. The issue was the voltage regulator had failed in the alternator and it was giving 15+ volts. Really, I was lucky all that was fried were the headlight bulbs. So, I'd suggest you check the voltage across your battery terminals with the car running and warmed up. Yes, you will need a multimeter to do so, sorry.
    • Good work to think to check that, and thanks for coming back to post up the outcome.
    • Given it happened suddenly, and when you come on boost, I'd check all your inlet - hose clamps in place and no split rubber or silicone hoses. Even the hard to get to ones near the intercooler. It's possible air that went past the air flow meter is being dumped out a big hole.
