Nearly run in ! 909Km on the engine now.

Just about to order a radiator upgrade too. A custom twin pass cross flow PWR radiator, so i'll be ready when the time comes to do the power tuning.

The run-in is now completed and I did the oil change last weekend.

I haven't done a full power tune yet as there are a few support modifications I need to sort out first. I have changed my old single core radiator out for a custom PWR twin pass with a spal thermo as well, which seems to work very well in the tropics. I also fitted an Apexi active exhaust silencer which does well to tame the exhaust note. I can talk to my passengers now, except for when the gates are open!

Tune wise, I have the low boost/low end to about 5000 rpm pretty much sorted. That's about all I'm game to do on the street though.

I have to do a few fuel and ignition system changes before I book dyno time. My day to day work and finishing home renovations has taken priority lately though. It will probably be a couple more months till I have some actual results.

I'm having a day off work today to install some of the parts I've been collecting over the past few months.

Another new PWR radiator (first one had clearance/fitment issues).

Set of ID1000's and a new fuel system and more Tomei parts (no e85 up here, so i'll be using a 110 octane race fuel for final power runs)

DBA5000 rotors and new pads

Updated catch can arrangement (fully enclosed and relocated so I can add a new oil cooler system)

Relocated power steering tank.

Water-oil heat exchanger

Its also approaching end of financial year so I've got a mountain of paperwork to catch up on. The good news is that I am preparing to have 2 more blocks machined up, which I am planning on putting in the hands of some tuning companies down south that are interested in developing / distributing the product. I am just sourcing the composite materials that I use to partially fill the block with at the moment, and then next month it will be off to the machine shop with it all.

Renovations are going well though too! Nearly all finished, except that no rooms have doors yet.

All sounds exciting mate.

Don't worry... I had no internal doors for 6 months... now that doors installed, they are such an inconvience, lol.

I moved back into my house again 2 weeks go, and have been able to work on the car again a little more regularly.

I have been driving it regularly when possible. There is now over 4000km on the engine. The wastegates now have 1.4 bar springs in them, and I have been adjusting the street tune to a 100 octane blend. This has made the car too quick to tune on the street for high boost levels. The data logging rate can't keep up with acceleration, so its defiantly dyno time to finish that.

I recently replaced all the suspension in the car with a Tein EDFS Active setup, ditching the Nismo Stunes that were in the car. Its so much more comfortable to drive, and it doesn't try and change lanes now as it comes onto boost in the lower gears anymore. Way more planted.

The hold up now is that I'm waiting on an under car surge tank setup. I decided to go with a new Aftermarket Industries design under car surge tank with Holly 1400 pump setup. Its going to be 4-5 weeks till it arrives so I am told.

The base machining of two more engine blocks is now finished. I hope to have them in the CNC mill in a month or two, and then will be looking to put the blocks in the hands of some tuners down Sydney/Melbourne way to see what they can do with them.

Odd question, but how does it sound?

A lot of people pan the 3L conversions for losing the distinct RB26 sound. I realise this well beyond a 26, but at least you've retained the block.

How would you compare the sound or do you have any clips?

Its got a tough cam'd idle at around 1000 rpm, but its possible to tune that out if I run a richer idle, and have it idle at 900 quite smoothly.

I have a trust TI-R 90mm exhaust on the car which is basically straight through, but I also have an Apexi active silencer in the tip of the muffler to quieten it down a little for when I am driving through the city. The difference that it makes is that you can have a conversation with your passenger. Downside is that it adds 800 RPM of lag, so it makes full boost at 4000 rpm now, not 3300-3400ish.

I've been meaning to buy a go pro or even a basic dash cam... Maybe I'll get the urge to do so this weekend.

Ive put a few more thousand km are on the engine as I've been driving it every day for work lately. Surge tank/pump is still on back order so Ive decided to upgrade the ECU as well now, and ordered a Haltech Platinum yesterday. The power FC is giving me grief with the resolution of tuning being too low.

Here's a quick video I took today of a walk around the car. At a glance you can see my new closed breather setup which drains back to the sump, and the revised cooling setup with the second version of my 70mm PWR twin pass radiator plus the oil to water heat exchanger. This is the trust Ti-R 90mm exhaust with the apexi 115mm silencer in the tip too. It quite effectively turns a track exhaust into something close to legal and streetable.

Yeah... It has been ok for a beginning, but its too long in the tooth now.

Just got a call from the office and my Haltech has arrived already. Ordered lunchtime yesterday... So I know what Im going to try and get done this weekend...

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
