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.

      It's the adhesive holding the ceramic wheel to the shaft the fails on 90% of them.

      Foreign debris, physical shock, boost leak, could be anything honestly. The danger in taking all the timing out of a tune/hitting the R&R corner is that even if the engine doesn't detonate your turbo is taking a lot of abuse from high EGT. Also, even if nothing goes wrong it is a journal bearing that is spinning at 100k RPM on boost. Eventually it goes through enough cold start/pressure cycles to wear it out.

      Possible option to replace central computer 370 V36

      By Vee37 · Posted

      I kinda accidentally saw this, and was interested, but It actually seems to replaces the whole center computer, using the existing screen and buttons. AND it may only be for a G37 and not compatible with a Japanese 370. So its not for me, but someone else may be interested to look into it. Its about $680USD. If I am understanding it right, it basically replaces/installs and android pc that integrates with the existing screen. But I could be wrong. https://gromaudio.com/vline/ The video I first saw was the following, with very little and unclear details.     Even if your not interested in the system, the video on their site was pretty comforting in showing how simple the whole centre comes out

      Import insurance in 2025

      I’m with Shannon’s for all 5 of our cars. Agreed values seem fair, premium price is okay. ($210 ish a month, all comprehensive).  Have claimed once with them for a not at fault claim with another car where my car had no damage. Was one call after the incident and an email after. Deemed not at fault so premium didn’t go up either.    I have called up and spoken with people who are not familiar with certain cars and didn’t agree with me on value or let their personal vehicle preferences effect the call. But called back later and got someone else who was more agreeable.
