Yeah had it running off the actuator and made 5 psi fine and spiked to 7 sometimes which i dont really care too much about, but it still felt slow. like it still makes boost and you can hear the turbo spooling but doesn't do much with it.

Its a stock skyline. U might be expecting too much :)

Get it on a dyno then u will know if it is making the correct power.

Yeah that is what i was kind of starting to think, but it feels slower than my mates old stockish 32 with an rb20det not a 25. its definitely not slow up top is just majorly lacking in midrange torque

Nah wasn't just going up windy point rd or whatever its called in 3rd.

Ok so took the exhaust off and went for a drive. No difference just made more boost (running off gate spring). still sluggish between 3-5000

Should probably post more about the drive with no exhaust. when boost builds the car just gets very loud and droney but once it is past the flat spot it sounds quite normal like it should. can't tell change in sound with exhaust on since quiet exhaust. So probably the timing is just hella retarded I'll hook up a timing light when I get the chance.

been a while since I posted here but I finally hooked up a timing light, set it at 15 deg, drove it, made it worse so assumed it was reading double, then tried to do it again but now it wont idle properly, like it will jump between 600-1000 rpm so i can't get a good reading for the timing. turning the screw on the AAC valve does nothing. also if i take the filter off the AFM (AFM still on car tho) it gets a lot worse, like idle drops and eventually stalls. also I connected up the VCT and that did nothing.

Ok so after doing a bit of research I found that I may not have the standard rb25det injectors.

Am I correct to believe that the standard RB25DET injectors are purple?

The plenum on the engine does not have the little nipple on the back of the plenum for the stock boost gage so I believe it may be from a non turbo rb25. (the plenum came off a different engine to the one it is on now)

The injectors on the engine now are red, As said before, am using rb25det computer so I doubt the car would run if non turbo rb25 injectors were used.

Help would be great guys

      Cleaning my wheels 😍

      By PranK · Posted

      A little follow up here on the ceramic coating.  We've had storms galore here and I've done a few ks, enough to gross them up  Consensus is that they didn't get as dirty as usual, the coating definitely repelled a little of the dirt and I think they kinda snowball. They get a little dirty and then they get dirty faster which makes sense. Cleaning them regularly would allow them to protect better.  Cleaning was a breeze. I tried first to just hose them off which, unsurprisingly, did nothing. But, making the wheels wet and then just wiping them over with a used but clean microfibre cloth was all that was required. I didn't need any cleaner at all, just water and a cloth. The wheels look amazing again.

      Gave her a nice wash today and took extra time to clean off the tree sap and tar and crap. We have a usable garage now so she'll stay cleaner longer. Took a few snaps in some nice light afterwards.

      OK, solid mount Z1 diff brace is in, pretty straightforward, it picks up 3 diff hat bolts and ties them to 2 support bolts on the subframe. Pretty sure someone else on here said they had reduced axle tramp with this but mine was already pretty good for smooth wheelspin, and still is....will see you this goes over time and whether I end up with a broken rear diff hat

      Mistakes were made, my R34 Story

      Ah yes, but the part in my hand was actually painted and fitted by me! I knew any front lip was likely to be sacrificial but I've had to fix it twice already... by the time I buy a fibreglass fixing kit, sort out sandpaper blocks, buy some fibreglass filler, body bog, spend the time and effort for a 'Greg' result... a new one being $290 seems like it's the better way to go and spray that with bedliner/raptor coat and we're all pretty again.. Would have preferred it last more than a month though. Them's the breaks I suppose.

      I find it funny that the USA is finding out all this really really weird stuff, and people from the USA are coming here treating it like gospel, yet, all the info on solving those issues is here on these forums for the last 15 odd years... Also, I know how much heat it takes to ignite the hood lining of an R33 skyline. I worked it out myself... It also took a LOT of time, and heat for it to do it... Big single, and I needed to drive the car, so retarded the timing off to "protect it". Yeah, that was a bad move for cruising on a freeway with only 15 degrees of timing on it. That was a lesson I learned around 2009. So that's over 15 odd years ago. Aligning water and oil, that's identical for any turbo engine, it's not Japanese specific. If a shop doesn't know how to make sure the core is rotated the right way, then they shouldn't be touching any turbo engine. That's not a matter of "We haven't had Skylines for that long here"...
