Plus I'm working on a VNT .82 rear housing for the G3s hopefully getting SS1PU's response with 330rwkws top end.

Eagerly awaiting results for this. Been tossing up between SS2 and G3 since we spoke but I'll watch how this devolps, VNT sounds like it will be pretty unreal to drive with.

Keep up the good work Stao :thumbsup:

with the SS2 and G3, do i have to send my turbo to you? i cant decide what one ile go for lol

Stao develops and produces them from scratch. send your turbo to him if you want it highflowed etc

G'day all,

Well I was going to wait until it was all done and dusted, but it would be the epic post of 2012. So I thought Id break up my Hypergear experience into a couple of posts;

Car is a Series 2 R33 with the following relevant mods

- 3" exhaust with metal cat

- Blitz return flow front mount

- Xtreme Cushion Button clutch

- Splitfire coil packs

- Alloy intake pipe with standard airbox

After running the standard turbo at 10psi for ages, I decided to try a Hypergear and bought the following goodies for the upgrade;

- Hypergear PU highflow (non SS1)

- S15 450(480)cc injectors

- Z32 AFM

- Gizzmo boost controller

So the car was pulled apart and turbo ordered. It took around 3 weeks for the turbo to arrive which gave me plenty of time to deal with some other little jobs;

I decided to replace all of the exhaust studs, as 2 had snapped in the head.

- Action Thread Repair came and pulled the broken studs out for $150

- New studs and a manifold gasket from Hornsby Nissan (great blokes) came to around $150

- The manifold REFUSED to go back on, so i needed to die grind the bolt holes out. This irritated ths shit out of me, as the manifold CAME OFF THERE a week earlier. Anyway, beware of this!

I also took the time to fit new injectors and seals

- Full set of Injector seals from Hornsby Nissan was $67

- One broken pintle cap replaced

Once the turbo arrived it was fitted up with relative ease. I note the following in terms of fitment;

- The water lines need to be 'encouraged' to fit. Mine seemed to fit okay with only a bit of massaging.

- The standard oil drain fitted and worked fine

- The dump pipe comes close to, but does not touch the air con drain. I heat wrapped the downpipe anyway.

- The whole exhaust was pushed backwards about 0.5- 1 inch

- It came with a standard compressor housing so my existing metal intake pipe fitted, but made it sit a little higher than normal.

With the piping all back on, the only fitment issue was with the whole piping arrangement now sitting higher. This meant that the standard crossover pipe does not fit down flush with its mounting bracket and the airbox snorkel no longer fits without hitting the bonnet. However, I'm sure I can massage/ manouevre it all to fit!

With it all fitted and running, the only noticable difference was that the exahust was alot deeper and louder. Oh, and that heatwrap f*&%ing stinks.

With that all done and sorted I had TOSHI come out to fit the temporary ECU before dyno tuning in a couple of weeks. TOSHI is a great bloke and I look forward to working with him in the coming weeks!

First run on the road and the car feels pretty good. There is nothing under about 4000 RPM, but from there boost builds quite quickly and it feels pretty quick. I am hanging out to get it tuned!!

Ultimately, it has been a little more costly than anticipated (to date) but that is to be expected. Hopefully all goes well on the dyno and no further headaches arise!

Anyway, just thought Id put my $0.02 up here in case anyone is interested.

Ill post up pics once it's all done.

Cheers

Chris

Highflow = standard housings bored out to fit larger wheels.

Highflow PU = standard housings bored out to their limits with even larger wheels. It's laggy but it does make a lot of power.

SS1 (super street, version 1) = a small, responsive turbo like the small HKS turbos ~230-240rwkw.

SS1PU = same turbo, sacrificing some response for more power ~250-270rwkw

Stao should make a chart detailing the product family and what the numbers/letters denote, because it can be confusing, but if you've been following the thread from the start, it does make sense. PU = powered up, like the "R" version of a turbo.

around 280rwkw easy?

lol

how will his "Hypergear PU highflow (non SS1)" make 280rwkw easy when everyone elses larger turbos are averaging 260?

LoL

I guess you didn't follow up this thread. the PU high flow is a ATR43G3 turbo built with a stock compressor housing and a .82 rear.

Means it has larger guts and bigger turbine housing then all of the SS turbos. I've made 287rwkws relatively easy out of it, the average I'm seeing is 280rwkws.

I've tested it. it made less power through out all rev range based on same boost. It just acted as a massive air leakage. Anti surge comp housing is not recommended unless the turbo is surging.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
