Will it run - yes

Will it run well - no.

Change anything like a turbo which alters the airflow - it needs a proper tune. Given the size of turbo you'll also need a FMIC, AFM, full exhaust and perhaps injectors etc.

How did it go?

I Already have FMIC, exhaust, CAI, new nissan coils Blitz DSEBC, I blew the head in my old rb25 and I am in the midst of swapping it out for a neo. The engine bay is empty atmo and I thought I would take the opportunity to do a few things. Whilst searching for some bits and pieces this turbo kit came up and i just could not go past it. I will be building my old 25 with bits like poncams and heaps of other bit and pieces that I already had sitting there waiting to go on it as well as this turbo. But I thought It might be worthwhile bolting it onto the neo for the time being......

You'll get by if you set it to 8psi. Any more and you'll be well into R&R on an R33 ECU. I drove around on a close to stock ECU and it was really nice to drive, more progressive than stock, sounds deeper and louder, revs more cleanly, more lag....hahahaa. BUT you won't make much more than a stock turbo on 10psi as the ECU simply won't allow it.

Go get a Z32 ECU and add Nistune.

Turbo is good for ~230 to 240rwkw consistently. Full boost (1 bar) before 3500rpm in 4th. Heaps of torque (a bit more than GTRS) due to the fairly large A/R, but it has a bit more lag than the GTRS between gear changes.

and swapping a NEO head onto a R33 sounds like a massive headf*ck considering you don't have an aftermarket ECU.................??? :/

If you do have an R34 ECU then just ad Nistune. :whistling:

      Hypergear Turbochargers and High flow Services Development thread

      I know this one’s the BB one. My tuner did make mention about the actuator. I am curious about the VCT as well

      Might also needs a stronger actuator with the right preloading. With older 2019 built bush G3 units, BB upgrade or 21U housing down size makes a pretty decent gain in response as well.

      Need help/advice with bearing taper clearance, eccentricity and arp studs.

      By Desean Strickland · Posted

      Hey lads  so im finally putting together my rb30 forged bottom end and ran into an issue. I measured my main bearing clearance with arp main studs torqued to 60 ft-lbs using ACL H series STD size bearings and standard, un-ground crank shaft journals and got an oil clearance reading of about 1.3 thou measuring straight up and down and about 2.8 thou measuring at a 45 degree angle (just above and below the parting line). My machine shop said they measured the main tunnel and it was all within spec (they didnt say the actual measurement) and to go with a standard size bearing, which i have done and the clearance is too tight, I'm guessing because of the extra clamping force from the arp studs distorting the main tunnel. I was wanting to run about 2.5 thou main bearing clearance.  My questions are: 1. could i just use the HX extra 1 thou clearance ACL bearings? that would fix my straight up and down clearance making it about 2.3 thou, but then would the side to side clearance be too big at around 3.8 thou? 2. what actually is the recommended main bearing clearance for measuring near the parting line / side to side. i know its supposed to be bigger as the bearing has some eccentricity built into it but how much more clearance should there be compared to the straight up and down measurement? at the moment there is about 1.5thou difference, is that acceptable or should it be less? 3. If i took the engine block + girdle back to the machine shop and got them to line bore the main tunnel (like i told them to do the first time, but they said it didnt need it) what bearing size would i buy? the STD size bearing shells already slide in fairly easily with no real resistance, some even falling out if i tip the girdle up-side-down. If im taking material out of the main tunnel would i need a bearing with extra material on the back side to make up for it? this is probably confusing af to read so if something doesn't make sense let me know and ill try explaining in a different way. My machine shop doesn't come back from christmas break until mid January, hence why i'm asking these questions here. TIA for any help or info

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I bought the model back in Japan in Feb. I realised I could never build it, looked around for people who could build it, turns out there's some very skilled people out there that will make copies of 1:1 cars or near enough. I'm not really a photo guy... but people were dragging me in a group chat for the choice of bumper as someone else saw the car before it was finished as they are also a customer of that shop. I took the photo in the above post because I was pretty confident that the lip would work wonders for it. Here's some more in-progress and almost-done pics. It gives a good enough idea as to what the rear looks like!   I have also booked in a track day at the end of January. Lets all hope that is nothing but pure fun and games. If it's not pure fun and games, well, I've already got half an engine spare in the cupboard

      Well, do ya, punk? Seriously though, let's fu<king go! The colour and kit looks amazing on the car. Do you have any shots from the rear? I don't quite follow how the model came around. You bought the white kit and he modified it to match your car? Looks nuts either way!
