Ha ha. All done!!!! YAY!!!

Finished off all the little crappy stuff in the engine bay and under the car then at 4:30pm finally ran it on the starter to get oil flowing. Could hear every cylinder, nice.

Then started it for real, fired into life after 3 seconds : )

Drove to the servo and loaded it up on the way there and back, with the waste gates free so no boost to help bed in rings.

Came back, dropped the oil and put more mineral oil in and changed filter and hooked waste gate rods back up. Went for another drive, nice! Good to be driving her again.

Only problem may be that I need a new idle control valve :( as the engine revs (flares) by itself continuously at idle.

Sounds throatier than before too.

Thanks :(. In the end I think I owe myself 5K+ lol. Great experience, and knowing the fact you built it yourself!

Well, on the stock bottom end it was putting out 350RWKW on 17psi. So I'd be happy with the same amount (read 500hp atw). Mainly due to he stock gearbox, and I built it to handle the power reliably without worrying about what the bottom end is like.

Went for a drive tonight, and it's really smooth and sounds gutsy lol. I'm only taking it to 4500 to 5000 at the moment at part throttle. Put 110k on it lol.

I'll book it in for a tune once it's got some kays under the belt........we'll see.

great work sean!

looks nice. and i love ur display pic. car looks smooooth as!

cant wait to see the dyno results. sounds promising!

Cheers. They really like taking your money lol.

Unplug it. Need to meet up for a cruz soon when i get my car back.

I'll try it out Brad. I also need to make another dummy load for the hicas solenoid I pulled out of the engine bay to stop the computer thinking theres a fault.

Cruise, for sure. I'll do the Putty cruise in October now :banana:.

Damn Sean, very nice and very fast work - fkn great effort!!

going to bug you for a ride in it soon if i get a night out i'll bring the SLR and take some shots!

Thanks Chris. The engine covers you did for me look awsome with the polished stuff so kudos to you. When we get a chance (read time off from busy schedule) for sure.

unreal sean. ive booked the gtr in for tune weekend after the long weekend at uni group. so will all have to go for cruise very soon. i just need front bumper now!!!!!!!!!!!

I'm glad it's done. Now done over 200k, and it's smooth as. Will be great when you get yours tuned.

I'd also like to thank everyone who gave some advice and imput on how to go about doing this project. 3 months seemed forever to me but it was pretty quick in the end.

Okay! Put 1200km on it so far, changed oil and filter again at 1000k and check up and tune on dyno is booked for tomorrow morning (only good thing about shift work lol). Gonna check a/f ratios etc, to make sure it's happy when I use the upper end of the rev range :P .

It has a pretty beaty, cammy idle, only using 12psi to be safe lol. I guess I'll have to check nuts and bolts are tight too etc. Twin plate clutch is great compared to the triple I had for the street.

Also the engine has no slap or rattles when started and warming up. Engine builder I took the block and pistons to, recommended running piston to bore clearance at 3.5thou so I'm happy.

Congratulation Sean..

Amazing how quick the build was done mate specially with work space..

Looking forward to updates.

Cheers :(

Okay, got it dynoed and cleaned up this morning. Found a couple of things. The fuel reg might need changing as it's a bit sus when revs are high at full load, more fuel was added to compensate but not too bad as it's on min 11 PSI boost anyway. Ordered in one from nissan. It idles at 1400RPM, idle control valve is letting too much air through(o ring inside is non existant), and I cleaned the throttles :D even though I read a topic about not to do that years ago!! It takes the sealing coating off the inside of the butterfly to bore seal.

Other than that, all good and since cam timing is sweet the gaph is great. It'll go back to the dyno in 2000km to get a high boost tune lol.

      Low oil pressure after WOT

      By pogman · Posted

      I much prefer that to an actual oil pressure issue, never would of thought it would of been a volt drop issue but SAU brains win again. Guess ill be turning down the oil pressure limit for the track and hunting some grounds. Ill hopefully update this thread with some high oil pressure and solid ecu voltage logs.

      Question about BoV on RB25DET NEO

      By Murray_Calavera · Posted

      You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster.

      Question about BoV on RB25DET NEO

      By Kapr · Posted

      Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!

      That dirty voltage drop is the culprit I suspect
