my last post was clear as mud, the point i wanted to make is that its like shifting a truck with the low rev limit.

i havent been that gentle with it :) my question is do i raise the boost/rev limit or wait till 1500km?

How much head work did you get done by Greg @ proengines...?

I have a 30 built by Greg and just sent a 26 head over for a little upgrade. Will be interested to see how your setup goes.

I will be running a T51 with 1.05 rear and C4 auto.

im running stock valves, 14hrs of porting was done blending bowls, open exhaust ports, spot face for larger lobes, match port manifolds and full service head

if i missed anything im sure greg will correct me

All calm...sorry Shane...buddy cuddle?

Nothing DiRTy about a 30...lol...ive just bought a nice set of Argo's...hehe

Yes Marko...give it some stick!

ok paul, but be gentle :)

Paul, that forklift is a diesel, maybe you should post it in the diesel block thread? :)

:(

At least the Nissan is infront of the Volvo.

Yeah Marko/Greg that would be good, im looking for someone to do headwork for me very soon, my normal guy is tied up for ages. Looking for max flow. I know a mob in S.A. have got some good numbers, but local would be nice

steve, flow figures should only be used as a guide, if u go chasing 'max flow' u'll prolly find the head will be worse than a stocker.

the results u get from a flow bench are only static volumes, i.e flow in cfm is only measured at set lift heights and they dont take into consideration the rapid change of lift variations from an engine running in the real world (valves open/closed thousands of times and varying amounts)

have a look at the thread i posted about a head i had done recently

hey nick - jim wants me to take it to 1500km, he will then raise the rev limit from 5000rpm to probably 8000rpm? he will also raise boost to 13psi & lean out the fuel, as advised.

he then wants me to take it to 5000km then perform the final tune with full boost & dialled cams...jim is being overly cautious which isnt a bad way to operate.

...im not waiting that long, as advised by greg @ proengines, do the 1500km then let it rip - the block was 'tunnel honed' which helps rings bed in.

Add me to the Paul and Rob list. I've posted it up eleventy billion times, run engine for 20 minutes, until it is nice and evenly warmed up to operating termperature and change the oil filter. Then drive to Bathurst, have breakfast with the guys to let the engine cool a bit and then drive back, that's around 450 k's. What I don't see on the list above is the next step which is "check the leak down". That will tell you if the rings are beded in, the bearings were run in by the time you got it out of the driveway. If the leak down test is OK, then drop the mineral oil, change the filter again, fill 'er up with synthetic and off for the final tune. This pussy footing around for thousands of k's achieves nothing.

Cheers

Gary

a. the 1st 300km i ran run-in oil

b. im now running a new filter with mineral oil

c. next change @ 1500km to full synthetic

im doing the bathurst run tomorrow :( with a mate who owns a worked Ford XBGT, nice car rumbles like thunder (harley equivalent on 4 wheels)

rob & paul...am i really that bad with my emails :) u've given me a complex, i feel like a STOONK C*NT

Marko, that was torqe plate honed. As I said, oil change @ 500, one after that and let rip.

I saw a car driving along the shoulder of one of the parkways here doing about 20km/h with RUNNING IN on a big cardboard sign in the back window. sometimes you've got to laugh.

^^ Yep..thats the correct way to break in an engine properly.

All my engines in the past were fired up on the engine dyno...oil temp reached,then start giving it a few pulls under load to 5000rpm..then pull the string and give it everything .

Engines leak down perfectly.

No way would i be pussy footing around for hundreds or thousands of kays.

Start giving it boost & rpm.

Motor initially run with penrite mineral oil ..half a dozen full power pulls made..then oil & filter dumped switched to royal purple 10-40,then back into it with full power runs.

Only way to do it .

And i have seen hundreds of engines dynoed & run this same way..all with the same results.

i remember coming across this article a while back when i had my bike - there are a few guys on gixxer.com which swear by this method - it is a good read

told you you'd like the clutch.....

good work Marko

dennis, its drives like a normal clutch, i gave it the wife test and she couldnt believe it as well, after having a triple then twin plate i will never go back. ive been questioning JB clutches and had the opportunity to get 1 two times in the past but i chickened out my mentality was "as if an aust single plate can hold like a jap multi plate"...i should have listened to paul from the onset

it feels like a standard gtr clutch just a bit springier (for lack of a better word) - you would never know its modified.

after looking at it, i think its the way he utilisies the thrust bearing on the clutch fingers as it sits closer to the tip of the fingers on diaphram then what it did on my previous twin plate.

its get more leverage like this & it feels nice with the 4000lbs pressure plate - maybe u should speak to jim berry direct about this, he'll chew both of your ears off :P

definitely do not wait 5000kms to give it the full tune and full boost. the engine will be half worn out by then let alone run in!! lol.

listen to greg. he built the thing. between 1000kms and 5000kms nothing is going to be achieved by running on a rich, conservatively timed, low boost, low rpm tune. except frustrations and boredom!

if you've done 1000kms then it's well and truly ready for the full ponies! :( get the wick turned up and enjoy. :)

how light could it be? The NPC Twin plate we have in the race car is lighter then the single plate in my road car....it shits me, because it shouldnt be like that!

Is that the solid or sprung centre NPC twin plate?

Looking Good Marko!

Where'd you get the silicon hose cooler kit and fuel rail from?

Thanks

    • No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️
    • Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney
    • I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"  
    • Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

    • Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.
