350z diff and shafts in R32
Butters replied to Komdotkom's topic in Suspension, braking, tyres and drivetrain
@GTSBoy posted a good link, happy to answer any questions that thread doesn't. -
Gearbox rebuild/upgrade Getrag v160/233
Butters replied to Diomedes's topic in Suspension, braking, tyres and drivetrain
Neat as posted rebuild them. They are noisy as heck though if you don't have the factory damper flywheel. -
I hear this a lot, specially from motivedvd but rarely see any data. It's also not usually all gains , some trade off is at play. So its about getting a setup fit for your purpose. I've had really good success with smaller .8 rears on RB26's, always wondered about going larger but a back to back test is very expensive. Be great to see some data to sway the expense. I'm not in the 1000hp plus region where i suspect larger rear is always going to be better.

On G series ? or more in general , any back to back dyno sheets kicking around ?

Normally really informative videos from Real Street but this was another advert

He has stated in previous video that the brace was built for 4wd adaptions. Then they noticed blocks crack less. Yes walk is it's feature but also this from the PRP site. "Aftermarket diffs crack blocks! it’s a fact, the Platinum Block brace will not only stop block twist, but stops the diff snapping the block under load, energy is dissipated through your 40mm thick integrated and webbed brace, blocks cracking and snapping become a thing of the past!"
-
So this was a fun watch. Seems a lot of value in an N1 block over a standard, specially for the power levels that are not going to split bores(1200 + ?) . It does make you really question the value of a brace.
-
Bit sad really, turns you aware from what actually might be a good product.

Watched this yesterday, a lot of BIAS as they are now selling them but given how little info around I thought I would share. They claim 15% power increase ... yer I wish, love to see this comparison if anyone has seen it. So far the advantages over a 6 boober seem to be : Comes with a gate flange Lighter - 5kg ish ? More compact - better AC and would help reduce heat transfer Has a heat blanket option Downsides : Clearance of studs(6boober has this too) Higher cost Reverse rotation turbos only( big issue for those that have a turbo)
-
The heat blankets have a price now . Seems very reasonable in todays world. https://artecperformance.com.au/products/nissan-rb-v-band-reverse-rotation-thermal-management-blanket

That was my first thought also. I dropped coin on a frenchies kit, which is really awesome but be nice if the factory stuff all fit better with 6boost. Not sure how I feel about the compressor outlet being so close to the manifold though. Very keen to see one of these with a heat blanket over them.

anyone on here ?

Speedo WTF?! Theories please
Butters replied to GTSBoy's topic in Suspension, braking, tyres and drivetrain
Wouldn't reducing the gap between the magnet and cup increase the reading ? IE some metal filings finding its way inside and would give an intermittent experience depending on where it is sitting. The other failure point would be the spring ? -
I am using this one - https://raceworks.com.au/catch-cans-tanks/catch-cans/external-breathers/1-6l-black/ I have both breathers plumbed into the front inlets. The I have one of the top ones blocked off, the other into my inlet. Being on e85 and a street car i breathe a lot and despite the low baffling it catches most of it. Fills it on a night of roll racing.

And looks like they just released the big daddy RB version https://www.facebook.com/PlatinumRacingProducts/posts/pfbid0zrf5V3ne4bxAsqd4giMwcMKnxABZiy9qGNKweusafPMGckw18VWFy6e5fA1cqpFTl

You can get two different sized titanium nut kits(different makers), can't tell from pics but I assume yours are the 12mm ? Please keep posting pic's keen to hear / see all the good and bad ! Seems like you have a lot of clearance to strut tower, this is in the 32R ? Also interested in seeing potential space for a new turbosmart straight gate Also looks like so so much room underneath compared to a 6boost, not sure what you would use it for but I am sure the AC lines would appreciate it
-
Not sure what you would gain by swapping to the g35-1050, your result is very good and kind of better than my g35-1050 (.82) on a rb26. Stick with it I say.
-
Please report back here the results ! Also if you could throw them on some scales the verify the weight that would be awesome.
-
Anyone have any experience with these ? https://artecperformance.com.au/products/artec-nissan-skyline-rb-exhaust-manifold-v-band-reverse-rotation What got my interest was the 7.1kg, my last 6boost was solid 12kg. Not to mention it didn't fit... wait i just did I also like the off the shelf blanket option. I've had real heat issues with my current setup. The reverse rotation is a bit tits as it means new turbo and new piping.

frustrating fuel pressure issue
Butters replied to damnonrs's topic in R Series (R30, R31, R32, R33, R34)
As others have said, HP sold is not HP tested. 1050cc injectors are the first tell, a setup for 650 crank, not wheel really. The 044 should be able to get you to 600rwhp ... JUST. The bigger thing here is the fuel reg, you will need to squeeze those injectors and need an adjustable reg to do it. I've also had fuel regs run higher pressure at idle due to being faulty and then drop pressure when demand is on. I got suckered into upgrading fuel lines and pumps when all the time it was the faulty fuel reg. -
Zero point modifying it for power if you want NA. P plate legal by chance ? You can modify it for sound, 6 throttles, cams and extractors. You might make power, you might loose power. I have really wanted to see a G25-550 e85 setup on an rb20 neo, I think that would be killer. Please do that, so I can see it.....

MotiveDVD/PRP RB-block comparison
Butters replied to K_arlstrom's topic in Engines & Forced Induction
I found this recently too - https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ Have to scroll way down to get to the testing data. Some different results and calls out the difference between old and new blocks. -
Between the big exhaust and gearbox the trans tunnel in my car gets very warm, nice on winters day but not so much in summer. I lined the trans tunnel with stick on reflective heat shield, mostly at the top with a bit down each side. Huge improvement ! I know this doesn't fix your "hot box" problem but if you consider the temp normal, it fixes your experience. This is in my Cefiro but its the same trans tunnel as a 32R.

Need to give that 700 hp a bit of a dyno haircut as its on standard smoothing. Still very impressive even if it is 650's on an SAE CF.

So far seeing the pulsar make the same numbers as genuine and some big ones and big boost at that. They seem to be lasting too, yet to see a failure in some abused setups. Given they are 35% of the price it does make me feel a bit foolish paying so much. Happy to be educated otherwise , my experience is limited but with the above I am seriously considering buying one for my bigger HP setup.
