So its been a few months now of having the hypergear turbo installed in my series 2 rwd. Nuances aside like needing a new oil line and minor install issues i must say it is so far the best mod i have made to my car!!!!!

I have a few supporting mods - zorst, fmic, t-boost controller, walbro pump and safc neo. So far on 10psi i'm getting 186rwkw which is great. Im only on 10psi as the R&R was kicking in with anything higher.

Their is a little more lag than standard, though once on song the turbo reaaly pulls hard to redline. For the money i dont believe their is much else on the market. Service by stao at hypergear is great!!

In the next few weeks i will be booking in for a nistune at status tuning ala trent. if i could get around 220rwkw before maxing out the injectors i'll be very happy.

If i'm keeping the stock injectors would their be any other mods that should be done to get the most out of my tune? ie z32, new actuator, plugs, coil packs?

If your on a budget and want a highflow, go the hypergear!!!!!!!

Nice result allready!!

Ive been looking at these turbo's, hoping that the stock turbo on my R34 wud go so i cud replace it. Sounds like they offer a good "step 1" increase which is all id want.

You can get good results with FPR's and you can also end up with a bad result like a lean out. I think on a NEO with a FPR you should be able to get a safe 220RWKW with a nistune espicially with a good tuner like trent.

There's a bloke over here in WA getting near on 380rwhp with stock INJ's with a FPR and its in a drift car.

The only other mod id consider would be a EBC and maybe some splitfire coil packs as your gonna need em eventually with a NEO.

Interesting to see your results, keep us informed.

i'm a bit surprised your gains are'nt greater with the hi-flow at 10psi, i,m running basically the same mods but with full ces system for a return of 189rwkw on a stock turbo tuned by matt spry at pits, i,m interested to see what happens with more boost and r&r sorted what type of power you can really produce (i'm ready for turbo upgrade just not sure what direction yet)

goodluck.

Thats pretty good with 10psi. My stock turbo made 190rwkws at 14psi and the dam thing lost its turbine wheel on the dyno. Keen to see what happens with a better management system and more boost. Does any one know if the Nistune Chip works with the R34 Stagea ECU?

Does any one know if the Nistune Chip works with the R34 Stagea ECU?

I believe it works for R34 ECU (Series 2 Stagea) ....you will need to email the Nistune authorised dealer your ECU serial number to confirm.

[JECS ECU only] (RB25DET)

Don't think it is available for R33 engine management (Series 1 Stagea).

Well iv'e booked in my nistune with trent on the 8th of april. Hes going to change the plugs as well. I mentioned about the fpr and he believed that it wouldnt make that much of a difference with the tune and seeing as though i might get some new injectors in the future i might hold off for now.

As for the 186rwkw at 10 psi, i was a bit dissapointed with this figure myself as i had 185rkw with the stock at 12psi. I think with a quality tuner i would have a better figure but i was always was going to get the nistune. Regardless of the figure though the car feels so much stronger in the midrange and doesn't drop boost like the stock turbo did on mine.

I love the whistle as its spooling up as well!!!

i'm researching a valve body upgrade as well. its either going to be through rvo or maybe i'll get one sent over from mv autos and get someone to install it.

Depends on the turbo's efficiency range to. At say 10-14psi it may be similar to stock, probly only difference be a lower discharge temp. Then as you increase the boost it will pull away substantially.

A good tune getting rid of the SAFC will unleash a heap more to.

Below is a dyno sheet with Boost map of The ATR28G3 based on a worked 1.8L CA18det starts from 17psi to 24psi in a .64 T28 rear which is roughly size of OP6 (I don't think they are .63 thou) T3. This might not be relevant but I don't currently have any data of it running full potential on RB25det engine. RB25det Neo it should pickup roughly 20% more in response and 10% in power.

    • Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!
    • Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers  
    • This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?  
    • Sorry for reviving an old post, but I'm having the same hot idle tick issue. Did anyone ever find out what it was?  I have checked/ replaced Injectors Coils checked Lifter clerance (is at zero) Checked Cam lobes Replaced exhaust gasket and studs Would appreciate any advice this is driving me nuts
