yeah mine too, im talking from a standing start. hold the foot brake on (not the parking brake) and floor the throttle, mine will start spinning about 3 seconds later. as soon as i let off the brake, the fronts grab and the occupants of my car get whiplash lol

I don't get it though...I've dropped it down to 2nd gear when i'm at say 60 and planted my foot. Can't get the tyres to chirp. Car just takes off like a rocket...

Probably because your stall converter flares like mine till about 3,400rpm therefore your have more of a slingshot rather than a chirp....unless of cause you have locked it.

i think the quality of your tyres are actually 'too good' to do it..

that and i have a shit suspension set up.

i reckon it will go away with the 19" and BC's(when I get around to owning them)

and yeh, i have a torque converter lock up clutch locked on mine...

With regard to what Iain is saying, I'm not sure "easier" is the word, because it happens at much higher speeds and loadings.

I think because it is so much more consistent, you can invoke certain handling traits, like oversteer, much more safely; in that you know how the car will behave every time.

lol i know how to drive you ass hole..

i think one of my front struts are blown. its clunking every now n then.

so my next pruchase after these wheels are on are the BC's. then i can drop it on its ass again lol

On topic, (calm down ladies) I dont think you need the restriction removed unless you get a highflow as I can bag the wheels up now at takeoff (stock turbo), it is very different with a highflow and most likely gets worse the larger you go. Most likely I will hate the Garrett until the remap is done.

sorry i didnt mean you cant drive, but youll need to adjust the way you drive as the car handles differently.

dropping it on its ass wont help handling BTW

lol i know it wont help handling. i was joking.. mines dumped right now and its a frikin pain. shouldve listened to scott lol

Nice work Leon!

I asked a mate to look into this also, but after everything thats gone on, and your testing, its clearly so much bigger than we all thought!

It's funny how nothing seems easy on the M35. Maybe we should be all driving C34's :laugh: .

I'm now considering this a challenge and will pursue it to it's completion, be it successful or not. With knowledge comes (power?) the ability to find solutions to other needs/wants/problems that may crop up in the future, plus I love to learn.

It has also occured to me that if I have the ability to open the throttle a little more at say 20% (where I sit most of the time on the freeway) it will make the engine more efficient. If, as a byproduct of this, it reduces the injector pulse width with no or little change to cam timing I could have a sweet spot set up for a lean cruise mode. The point being, even if I'm not 100% successful in beating the throttle restriction above 80%, there could be an indirect benefit of this R & D work.

Is the throttle restriction in all gears and at all speeds or is it just first gear and under roughly 30km/h as it feels?

Perhaps it would be possible to trick the ecu into thinking it was in a higher gear or already going faster whilst still in first?

Does the throttle body ever open 100%

I like the way you think -outside the box. I'm not sure if that is a viable solution but I will ponder the implications & anything else related that comes to mind during the week. It seems that almost everything in our factory ECUs are tied to something else. Thanks for your input Steve. Oh, and max throttle I've ever experienced according to the informeter is 85% I think. In the last couple of weeks it's been nothing over 80%. Again, it's so many other factors which determine what the ECU allows you to do.:mad:

As for you other guys - you crack me up :rofl: It doesn't take long to degrade into a free-for-all lol.

      Can't you put the pistons to TDC and then do the valve seals? Or will the drop down too far to pull them back up?

      Replacing turbo water line - any recommendations or advice?

      By sunsetR33 · Posted

      One thing I can tell you is, do it properly the first time. If you encounter unexpected problems just let the car sit for a week or two if you have to get some other parts or figure stuff out.  I'd have said go and use as many OEM parts as possible but since you want to change the turbo later on a custom kit is probably the better choice. Since I have no experience with RB25 just compare parts diagrams and images before buying a line kit and it should be easy to see if it has everything you need. Amayama has very good parts diagrams and part number lists, that is what I used a bunch to figure out what I might need. And don't forget to plan ahead and possibly renew other stuff that's easy to get to while you're in there doing the turbo lines. Happy wrenching

      Update 4:   Hi all, good news. Engine is running and all the gaskets and seals seem to be working as intended. No leaks so far, even the JB Weld seems to hold. I flushed out the old coolant a few times and put in fresh coolant, not Nissan stuff, I decided to try the Ravenol Protect FL22, they claim it works for a wide variety of JDM cars and the opinions on it by some people were pretty good. And it has the nice poison green color! And man am I glad I bought a coolant system tester earlier this year, vacuum filling works wonders on this engine. I can definitely recommend this to anyone still doing it the old school way. All you need is compressed air supply. Will have to do a small test drive as soon as I can, I removed the gauge cluster again as the tacho needle was still bouncing around a bit but it was much better than before already.  I also found some cracks on all 4 tires inner and outer sidewalls. Apparently these tires should 't be parked on for extended periods or be kept under 0 degrees during storage, which I did not know. Clearly the previous owner didn't look into those details either, he probably bought them just cause they are cool semi-slicks. I'm just wondering how tf I am supposed to reach 30-80 degree tire temperatures on the public road consistenly, these tires were never going to work for my use case. I'll probably order Continental SportContact7 ones as these are the best allround summer tire available right now and I don't think I'll need anything crazier for now. Do let me know if you have experience with various tires and which ones you recommend.

      Not going to pretend I didn't do a bit of junky work this time around, but mostly due to the fact that some things I am not willing to spend days fixing right now, like wiring. I try to do most things properly the first time around.
