I quickly modified the drawings to better represent what actually got made lol.

Hopefully that will help. Just gotta be aware that not all the 4" clamps are the same, so these rings might not fit a different clamp, though they would go close.

Mufflers came in on friday. They are different to the 3" mufflers in regards to the internals. The 3" had three perforated tubes welded together in a triangle form while these 4" ones as you can see have one big 4" perforated tube in the guts. I guess this one will flow better.

Only took a week from order to delivery. Quick!

I also spent the weekend finishing off the exhaust ports in the head and I lapped all the valves in. All came up pretty good. Though the valves and seats were all cut last year so its no suprise they seated nice and easily with minimal work. Only spent about a minute on each valve with fine compound.

The exhaust ports and bowl area took me about a full day to finish off.

Should get my block back today for o ringing then back for hone and then ready to assemble. :)

Cheers mang! Im trying!!!!!!!!!!!!!

So, no reply to my pointless email friday morning punk! Whats the deal????

Sorry brother, I was spinning out on Friday from the previous two days in WA...

Those mufflers look much better and a much better option than butchering the other ones. Are they standard size valves? Are they OEM Nissan?

Understandable mate.

You are right about the mufflers. Im happy I aborted the dodgy option and did it properly.

Yeh the valves are factory. Stock standard RB25det valves.

Mufflers look good.. were they made in aus? if so by who??

Nice little clean up on the head too-

Twin charge- I'm loving it.

Justin, the mufflers are American, Borla is the name. Come on mate I thought you would have known that! :P They are very nice and all stainless, so well priced too.

Yeh, nothing too radical since im no pro. That was my first attempt at actually cleaning up the ports, matching, and some minor blending. Its amazing how bad it is inside there.

gonna be loud with that low level of deadening material

who is brett? should we call him? :P

is that pen holder made out of old muffler perf?

Yeh I reckon it will, so im running two in an attempt to reduce the noise. Though I have my doubts that it will work, however, performance first!

It looks like it! I got my nice string of paper weights, a CP piston, PPG dog ring, bottle of oil , 1mm oversize inlet valve inside the perf tube, further across are some valve guides and spark plugs you cant see.

lol. go for gold, so long as your not in Perth, I dont think it would matter!

  • 2 weeks later...

lol. tell me about it. Im still waiting on getting my engine back from machining. Was supposed to be last friday. Now it should be middle of this week. There will be photos when I get it all back and start assembling. :)

How was your trip?

Sorry I thought they were custom done locally, re-using the borla outer shells-

So borla made them in 4" for you... cool- loud though.

Your assembally photo diary should be pretty damn good.. I havn't seen a good, step by step bottom end build log on SAU yet.

They werent custom or anything. Just off the shelf mufflers from summit. Yeh, im worried they will be quite loud being straight through :(

I'll do my best to outline what I do when I check it all and put it all together. Though I'm no engine builder so no doubt it wont be as detailed or accurate as one from someone in the game.

pretty awesome thanks :), good to get away from everything for a while.

my machined bottom end has been sitting around for ages, need to find some time to get into it, hope that doesnt happen to you!

    • 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. 
    • Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.
    • Any G40/1000 or G40/1250 results out there?  
    • You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
