That's good you found it.

Did you have a bit of flex pipe between the waste gate and returning back to the exhaust?

No soild stainless steel 304 pipe. Thought it would be fine. Guess not. Might just change it to a screamer pipe. Never worry about it again

Yeah neo heads are good for 22.0 psi but damn if you touch 22.1 all your valves will melt.

nah the neo heads are awesome. much better than the R33 item.

This car has an entirely stock neo engine and 26psi or something:

28psi on high boost.

if it's your tuner and in specific reference to your turbo that's fair enough then... I'd imagine the tiny little rear housing will get pretty hot too...

In any case you are building a 3.0 and it's not my money so boost it till it pops and post vids

Was told that by 999 automotive. If I run 98 don't go past 22psi and if I run e85 then not to go past 26 27psi.

The guys at 999 Automotive don't know shit, not to mention they sell exhaust parts that don't even fit or line up.

What a croc of shit, I've run 24psi on 98RON through my stock as bat shit motor on pretty low timing (7~8 degrees) but was pointless because the manifold was glowing red as EGTs were too high.

yeah lol at set PSI, ok I'll run 22psi on a 70cm turbo from a mine truck, it'll be fine.

I love the neo head as well, simon doesn't like them though as they tend to ping more than the r33 one but they make more down low with a nicer torque curve due to the better VCT

Might be too much power for this thread but:

Neo head is good for 28psi. Or possibly more, This one haven't melt yet.

Running our very first ATR45SAT prototype turbo, externally gated off stock exhaust manifold. Stock standard, Unopened Rb25det Neo engine.

LOL go Stao!

is that your modified manifold or did you switch back to stock?

Thats actually pretty impressive for any 25..........be even more impressive if its a daily driver and lasts.

Still...they all said that 300 was too much for std motors but look at the number of owners doing that and the sky didn't fall.

So 400 is the new 300!!!

    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!
