Hey guys, My engine started playing up at the end of last year after some tune and spark issues. Compression was showing that each cylinder was still making reasonably healthy compression, but there

Thanks mod’s for approving :-) Firstly, I should explain that I’m running this build in ~3 stages Engine build & tune Cosmetic refresh (touch-up to paint, rims, nismo MFD etc– generally stuf

Sure did ;)

Oh fair enough what you aiming for?

Yeah he was quite proud of that head.

No real aim, she should put out around 350awkw, but my jap spec catback might be restricitve so i'm prepared to be disappointed. Once i get around to getting the 4" exhaust, finishing the fuel system and adding E85, it should churp out 400awkw.

with my jap spec exhaust and baby -9's I got 340kw. You will be fine :)

That's got my hopes up :woot:

Sounds like a cracker love to see it in action bro :D

I'm sure you will see it out and about very soon. Say g'day if you see me :cheers:

Also, forgot to mention that's it booked in for some work and dyno time for the week after next. Should be ready when i come back off shift on the 16th.

Thanks mate,

Failed springs arern't fun :-(.

I'm using Tomei Type B's with the titanium retainers. Didn't go with a dual spring set-up as the engine redline will only be ~9000rpm and the cams are still relatively small.

The tomei's are proven to be very reliable in similar set-up's so hopefully there won't be any issues.

Whats your reasoning for Tomei B springs with poncams. I used A's with 270/10.8 procams for 6 years and 80k kms still like new.

Swapped out for 260/10.25s procams now with new A type springs. Cheaper to!

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.

      Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
