All rebuilt...runnin in...finally get a few k's on er and give it a bit.

Doesn't really splutter, more of a hesitation

Feels like it wants to go, but mellow's out.

Goin at 0.6 bar steady..so I don't think its leaking.

I have a nisdat..timings ok, oxygen and af sensors seem fine.

It doesn't seem to retard as though the knock sensors are kicking in.

New battery, newly flowed infectors, new plugs...like I said it doesn't splutter like a lack of fuel or spark.

At a guess its electrical...any thoughts

Mine feels exactly the same.. Basically no notisable problems just no power..

Id get it on the dyno and see how much power shes putting down and check the af's.. PM me if you find the problem .. :spank:

yeah about 600..but I still would have thought as revs pickup power would too.

Another strange thing...my boost controller doesn't work now...but electrically does.

Something is cutting, I'm sure of it..fuel,boost??

Weekend will reveal I hope. Got a new fuel pump happenin and another gtr to swap stuff.

If I'm game, i'll free boost it in 3rd and take my foot off as soon as it goes over 0.7 as it only does 0.6 now.

sounds like boost leak or boost control issue, are all inlet hose fitted correctly??

very easy to miss a hose!! i have recently fitted a brand new engine to gtr and

tight will very little effect on boost achievable.

i also doubt fuel is issue.

it really does sound like leak or control issue, maybe turbo actuators partially open.

also check that you blo off valves are not leaking.

Has the engine been run in properly?

 

I wouldn't be reving upto 6k inless you have done atleast 1,000k's.... Before then you should be reving to 3k.

Lots and lots and lots of theorys on how to run an engine in...

But yeah, Id say how all your little hoses are hooked up, just if stuff was working before, and isnt now, its more than likey going to be something small that would be easy missed. Such as forgetting to put a piston in, thats big stuff, it just wouldnt happen. Putting a little hose on the wrong nipple, thats easy as to miss.

      Oh, I forgot too, all the multimedia stuff captured and sold through things like people playing Pokemon Go. Pokemon Go specifically, can actually be traced all the way back to a CIA investment company too. So yep, they're watching everything. Not to mention the new stuff where they've worked out how to use WiFi signals to be able to map occupants inside of a building. That one would be something that I see being more used in public/government buildings, as you need to understand the signals when the room has no one in it first. It's not as easy as Hollywood would like you to think it is.

      Followed ☺️ Assuming those are NEO rods, then at least 400kW all day.

      Great work! Give it a clean up with some Emery paper, and I'd run a thread die over the threads too to clean them up. It will make reinstall much easier, and also life easier for the next time it needs to come out.

      I'm not a fan of high humidity, it's one reason I don't mind being further inland out Ipswich, except the last 3 odd years, the drought broke, and it won't stop raining, which is making the humidity nearly unbearable when the rains are in during summer! For me, my body hates the cold, once the cold sets into my body, I'm totally screwed. I end up with severe muscle spasm in my back/shoulder muscles, and it feels like someone is trying to tear the muscles out. I have no issues with it getting stupid hot, so long as the humidity goes away. So the last 3 years as above, have been woeful! Ha ha. However, June 1st, and I'm only just converting from shorts and a tee, to long pants and a t shirt. And that's mainly as it's a bit wet and miserable and I wanted to work on a car.
