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

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.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure

      Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.

      Starter motor replacment teeth count.

      By oHBoy. · Posted

      Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15

      J50 clock date suddenly reset to January 1

      Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.

      8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
