Ryan G from 2bartuning

I'm wondering that nobody mentioned him before. He is a genious. Just search for his Name here on imoc for example and you will find lots of interesting thread.


edit: seems I should read posts till the end first Ryan is a top man and I think would wait for him

me too

On the other hand, the fuel pressure of nearly 5bar seems a bit high at idle? Must admit I only skimmed through :oops: 5bar idles crazy (full boost could be knocking on 7bar anywhere between 2 to 3 bars were you should be at depending on mapper .. I tuned mine and i was no where near that high ... ...

Ok thank you very much. I thought the supra pump is capable of a little bit more.
My FPR is a SX Performance 15404 with 6AN fuel lines.

So the genuine Toyota fuel lines should be fine and it is just the fuel pump?

[quote="bobhattonIt sounds like your pipe work and intercooler has a high pressure drop. What is your fuel system, pump, filter, hose types and size etc.[/quote] Yes, it sounds like that. Should be something like 0.3 bar according to the boost drop. I am trying to source a free sensor Input on ...

Hey, as I now solved the problem wirh the dropping boost, thank you all very much, Inow discovered the next problem. As I am now able do drive 1.5 bar over 5000rpm my fuelpressure begins to drop and the limp mode of my ecu was activated. fuelpressure 4,8bar at 5000rpm drooped to 4.5bar at 6000rpm. I...

:D everything is fine :) so the only bad thing was taking the wastegate actuator operating pressure from the compressor instead of from the intake manifold. Bow with the higher spring rate actuator, the car boosts 1.5bar well beyond 6000rpm. Unfortunately at 61xxrpm my fuelpressure dropped too much ...

Well, that squish testing was some fun. And I still don't know, if I got the solder straight till the end, as the biggest solder I had was 1.5mm and it wasn't touched by the piston and head, so not squished. So either I have more then 1.5 mm squish, which is within possibility, or I didn't push it f...

No, unfortunately JUN didn't respond to my email. ATS answered quickly but they didn't know the lobe center themselves. They only suggested to use the backplate marks to start from and doing the rest on the dyno. But I found out that the user NoddE has exactly the same cams and he gave me the follow...

Check that the adjustment nut on the FPR hasn't worked loose :thumleft: Yep, wll do so. Checked my older logfiles. There was everything working right. So this is a problem, but a new one. Here you can see that everything was spot on (despite the quite low oil pressure :? ) some time ago: http://i28...

Oil pressure might be within the acceptable values, even if at the lower edge. I measure it at the top of the head, where the oil pressure genuinely is measured, too. With warm oil and only 2 bar at idle it is not uber-brilliant, but maybe acceptable. Which makes me think is the fuel pressure. I hav...

Sorry for the monologue but while looking at my logfiles... is that oil pressure ok? It is 10W60 and has reached about 80°C but only 2 bar on idle and 3.7 bar on full throttle.... is that ok? On the other hand, the fuel pressure of nearly 5bar seems a bit high at idle? http://i283.photobucket.com/al...

Well... had quite some research and thanks to NoddE I found the center lobe of my cams:
intake 110°
exhaust 115°

I will try to see, how much my cams are out of this and let you know

Hello everyone,

does anybody know the lobe center of JUN 264 intake (1004M-T002) and exhaust (1004M-T102)cams?
I contacted JUN themselves (as well as several aftermarket sellers), but unfortunately I got no answer

Thank you very much

I disconnected my wastegate actuator and the boost went up to 1.4 bar quite quickly. That sounds like your boost control is not working very well. Try a manual boost controller and see how your boost goes with that Yep, that was no boost control working at all. I disconnected the wastegate actuator...

Thank you very much for your explanation. Just got confused as my friend is using a 1.5mm headgasket and a stroker kit on his Skyline RB26DETT engine without any problems. ATS is a good advice as I only had negative replies by now. But well, tomorrow is the first day after the 4-day bank holiday in ...

Yes, maybe I try and post a new thread where looking for info from someone used them here. Fensport unfortunately doesn't sell these cams and I got one reply so far, from nengun telling me that they don't have any paperwork :( weird, as they sell them. I told them, that I am willing to pay for the c...

Nope. I guess there is bank holiday in Japan, as today and tomorrow were marked red like the weekend days.

I think I will try and contact several companies that sell these camshafts as well. Maybe there is one, that sells me the specification sheet separately

Trying to find some gen on setting up the JUN camshafts, do you have the part numbers your ordered? Intake cam: 1004M-T002 Exhaust cam: 1004M-T102 and now off to read bob's links. Thank you very much everybody. It helps a lot and I feel so much better after today :) edit: back and definitely buying...

Yep- looks good, just eliminating possibilities... Yes, and thank you very much for that. Always welcome. A faulty wastegate was what I had in mind some time ago, too. Maybe a crack in the seat. The wastegate itself operates fine and is completely free. Can close and open when putting pressure onto...
