The CE28's look the best I reckon... LMGT4's are definitely cool though... tough choice hey!... top shelf parts selection and you got it built at the right place... now stop holding out on us, we want to see the dyno chart!

Agreed the CE28's are my favorite wheel. :domokun:

A Power FC retune yielded a slight increase in maximum power output, possibly due to larger intercooler:

I will keep this thread alive by updating periodically

Hi,

Just wondering, this power was achieved on standard injectors or?

What boost pressure did was it on?

Beautiful 34 you got there, keep up the good work.

Cheers

Grant

Hi Grant,

The power output was achieved with standard fuel pump; standard camshafts; and standard injectors. Its surprising sometimes how good the factory stock parts work.

The boost pressure was about 1.3 bar, with NO electronic boost controller, just HKS actuators and a factory solenoid with a bung in one of the hoses.

I guess that is Racepace tuning philopsophy - keep it simple and achieve maximum result! (BTW I have no affiliation or financial interest with Racepace.)

Thank you for all comments and encouragement!

Better do something bout those brakes. Look a little small behind those rims.

Since someone mentioned brakes, below is a detailed pictorial of the AP Racing 6 pot front; 4 pot rear Formula Big Brake kit.

Stupid qestion one for the day:

What is V-cam?

V Cam = HKS variable cam on intake side for RBs

Aaron34 Posted Today, 12:01 PM

Hey, you should have just bought my car instead and saved yourself a fortune... What exhaust are you putting on it now if the RPM single is coming off?

Hey Aaron,

It would have definitely been alot easier just to buy your car, but then I miss out on all the fun and excitement of building my own car to my own specs.

In terms of cost, it ended up almost the same as the 'trade in' price you wanted for your car at that time :laugh:

One of my friends is interested in building a RB28 GTR, so I will try and convince him to look at your car if its still for sale!

As for the exhaust, I had one made similar to what Ben has in his R33

Extract from HKS European website:

Using variable valve timing technology, V Cam System evolves the RB26 engine to a new level. HKS V Cam System for RB26 addresses the issue of low-mid rpm torque whilst allowing the engine to continue producing power at high RPM.

Features:

The intake cam side of the RB26DETT is changed to allow variable valve timing. The Cam used has a duration of 248° which can seem a little conservative. However with the variable timing, power increases can be found at low or high RPM

Whether you are looking to find some time on the circuit through improve acceleration out of lower speed corners, or simply want something which can overtake with ease on the street, the HKS V Cam System provides good power from low RPM reducing the necessity for excessive gear changes. This especially noticeable when going from vacuum to boost to give the feeling of increased displacement.

Improved valve timing will allow for more complete combustion leading to improved fuel economy and cleaner exhaust emissions.

HKS V CAM System is available in 2 versions. Type A, which can be fitted to a standard engine (Valve timing adjustment 30°) and Type B, which can benefit from further valve timing adjustment (50°) through the use of HKS Pistons.

Type A was chosen as car is intended to be street orientated.

Hey Matt

Did you import the V Cam kit yourself or did you buy it from an HKS dealer here. The reason why I ask is if you bought it from o/s, you're going to have a tough time getting it tuned properly in this country as HKS will not supply the software to tune the kit unless you bought it through an Australian authorised dealer. Someone I know went and bought his kit o/s, got it installed through Bel Garage but could not get the software to tune the damn thing.

So just be wary of that.

Either you haven't got your labour bill yet, or the parts you bought are hot. At my advertised price of 89K, I'm not sure how you could build up one of these including the car purchase price. I know mine has over 100K spent on it then there was the price I paid for the car itself...

I'd love to get around to putting the variable cam set into mine one day. Its already insanely torquey with the 2860 -5s and the 2.8 HKS step2 kit.. (plus all the other top secret stuff of course) I'm still running the standard intercooler and plenum. I see you changed both of those... Is your's running yet? I heard it might be..

Hi mxfly,

I had this discussion with Racepace prior to ordering the V Cam and Ben guaranteed 100% that he will be able to integrate it with the Power FC with no software of hardware technical problems, and guess what... the man delivered! I privately imported the HKS V Cam direct from Japan. I managed to find a copy of the installation and software set up manuals in English which helped a lot.

two_evil Posted Today, 07:02 PM

yeah exactly i think you need to use a hks f con v pro to use the v-cam. other wise u can't tune it. sucks ass. i think you might be able to haltech to control not 100% sure

Hi two_evil,

I was a bit sceptical at first whether the V Cam will be compatiable with the Power FC, but the result has proven that it works very well. I was told that the Valcon does not talk to the Power FC at all, it merely acts as a piggy back computer changing the Cam angle according to engine speed in rpms.

Initially I was going to buy the HKS f con v pro, but the cost is prohibitive and HKS will not sell you one unless you purchase direct from the Australian distributor and on top of that, no one can tune a F Con except the distributor in Sydney.

I took a bit of a gamble to outlay the cash for all this V Cam stuff when I only had one man's word that he can make it work. It just shows how much I trust my workshop.

Hi Aaron,

Your car now at $89k is an absolute bargain for what you get! Back then when I inquired you about it, you were a lot firmer with the price.

LOL regarding the 'hot' parts.... I actually have good contacts which allowed me to get exceptional deals on JDM car parts, besdies the Aussie dollar at the time was in my favour. I must admit the labour cost was the killer. Don't forget your car has fully tuned suspension, drivetrain etc. which my car does not.

The car is running well, I will post dyno graph soon.

Matt

I hear it is awesome. We should meet up and swap some knowledge. I'd love to suss out the VCam and I'd be happy to take you over the rest of my car and where all the time and money has gone...

Beno knows how to hit the bullseye with all of it now, but it took time. The 33 is a totally different chassis. Great thing with Beno is you feed back the cars behaviour and how you want it to behave and after an exchange of time and money, you get exactly what you want. I don't know anyone else that can do that as well.

I've only put about 3000 ks on mine in the last 20 months, basically since the build. Damn waste. Winton in a couple of weeks should be a good test for it...

Hey Aaron,

The issue I have now is that the car is too fast for me to handle safely, I get scared when I go full throttle. :)

I wish I had driving skills like yourself, Chris and Jack.

I need to learn how to drive the car! Definitely catch up.

Cheers

Matt

    • I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....
    • So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.
    • our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
    • What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
    • Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.
