Picked up my car from Unigroup engineering today

Results are as follows

GCG r33 gtst housing high flow pumped out 254.7kw at the wheels but detuned to 243.8 due to intake pipe gettin vacummed sucked.

Specs are as follows

Greddy profec 2 boost controler

Bosch 040 intank fuel pump

Standard air box with filter

R33 gtst GCG high flow turbo

3inch dump pipe and exhaust in stainless with a xforce twin tip muffler for the sleeper look

Just jap return flow front mount intercooler painted matt black

Nismo 555 cc injectors

Z32 air flow meter

Power fc

NGK coppers .8 gap

Standard coils

The 185.5kw was made on stock turbo, SMIC, standard airflow meter, standard air box and 3 inch exhaust, at 12psi

Ive actually taken the time to look at alot of results, and no matter how mild or wild the setup, the exhaust cam gear being retarded 3 or 4 degrees seems to tune out that dip before 4000rpm when using stock cams.

If you check, most setups that have stock cams will have that dip bar those with the exh cam gear. You may want to look into that along with the rev210 intake mod.

Great results too, congrats :P

Thanks for support guys.

Thank God for SAU, great resource of knowledge and Top bunch of blokes.

i am very pleased with the result however i will need to sort out that intake pipe issue. i just finished reading the how to guide and its an option. Are there any other intake options available eg aftermarket.

ideally i am trying to keep the car looking very stock and sleeper looking. not interested in attention as its all about the go for me.

One more thing, the car seems to be hooking up well with very limited wheel spin. I was expecting spin city but the car feels refined and linear in its power delivery. I am running stockies and they hardly brake traction when comming on boost. A little side ways action is all i get.

have others experienced this with 250kw?

it depends on suspension setup/tyre choice/how hard and fast the power ramps up.

if i put lots of preload into my wastegate its all in a little after ~3500rpm and pushing 300+kw and steps out in 3rd but if i back the preload off and the boost ramps up much slower it holds on in 2nd fine and almost holds 1st with only 235 rubber

Got practically the same (245awkw) in my Stagea with GCG turbo and same gear as yours but chipped ecu instead of pfc (chart in rb25 section). Had a adjustable exhaust cam gear - set it to 4deg ret as per SK's suggestion and a year later when i got it set on dyno the ideal setting was near enough 4deg bang on. Stagea being awd and lsd did not spin wheels with 17/245 8in rims in the dry.

We sound very similar in that regard!

I have also been on the search for an intake pipe to connect from the airbox to the standard turbo compressor inlet. The how to guide is supposed to be very effective. I was going to spray the metal pipe black as well for even more stealth.

The only aftermarket one I have found is:

http://cgi.ebay.com.au/SILICON-INTAKE-PIPE...=item255a132f3d

When I ask him whether it will bolt up to the std airbox he keeps saying "yes it should", which is not the sort of rock solid answer I am after.

The guys on here keep saying to get someone to make a custom one up.

a few of those things dont fit at all (especially r34) so just be wary. The factory one is fine with a insert.

I have a silicone intake like this. Not the same one. It fits with the standard airbox (sorta). It moves the position of the airbox over a bit so my airbox is only held in by 3 bolts. So yeh, it works fine but just not 100% perfect fitment wise.

the metal piece you insert (the mod that's been referenced) is not really visible at all. Do that, it will look more stock than the silicone and cheaper.

Similar power to you and with good/new 225 tyres holds traction pretty well. I have noticed now that the grip isn't quite as good (tyres are now about 10k kms old, 12 mths old). Will spin up the top of first and in 2nd if road isn't flat. With fresh tyres it would hold. Be careful with the power. I have stock suspension and brakes.

Hello,could i ask how much your tune cost,i need one myself,you can pm if you like. Genelle. :cheers:

$750 standard unigroup price

These guys go the extra mile before they tune your car.

They bench flow injectors to determine flow rates and spray patterns.

They smoke test your motor to determine whether there are leaks in the piping system

yavuz has a degree in mechanical engineering and he has specialised his work to car tuning which makes him a pro at what he does. Over 15years experience in car tunning, he started on carbies. He is a power fc freak as well.

good service and very informative, worth paying the extra to know he has put the time into refining your machine. remember , tunning brings the whole package together, can make or break your motor. When he tells you he has tuned your car to be driven hard, you know it will last the distance.

Good luck

I say screw the silicone intake pipes that are out there. I thought I'd get one so that I didn't ever face the issue of having the standard rubber one suck closed. I was a bit disappointed with the fit. I tried trimming stuff as best as I could but it just didn't sit right. Since I'd trimmed it I couldn't really send it back. I also wondered whether the standard rubber one was actually a stiffer construction, it just didn't impress me (can't remember the brand so some might be better). Some silicone ones I've seen have a metal spring/reinforcement on the outside but this pipe doesn't see positive boost pressure so I'm not sure that would even do anything. The rubber one has all of the extra external reinforcement to brace it all. I just threw the silicone one out after seeing the metal pipe mod. A local exhaust shop was really good and I got a piece of 3" stainless for free. A knife, couple of hose clamps and some tools to cut/ tidy up the pipe was all that was needed. To keep it looking more stealth make sure the hose clamp screws/ bolts are underneath. Put the 2 ribbed rubber section you cut out over the pipe and match up the cuts so the only difference is the two stainless bans of the clamps showing. This is a great mod as you won't suck the metal closed and it's cheap to boot.

    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
    • Thanks for that, hadn’t used my brain enough to think about that.
