G'day Guys,

I thought I would post in this section regarding an issue I am having with my 32 Skyline (1993, Manual, Exhaust, Intercooler, Pod - 170,000kms)

I haven't driven the car in roughly 3 months since I am afraid I will break down on the way to or home from work (There is no areas to pull off the road due to so much construction).

The issue started on a Thursday where I was in very heavy stop & go peak hour traffic I got 1/2 way home then while sitting at some lights and about to start going again the revs were fine to about 1,500rpm then it just cut out and stalled. I started it back up and would just keep cutting out till finally feathering the pedal and riding the clutch pulled off to the side of the road and around the corner the car stalled, I sat there for 30 seconds and started the car up again and it was idling normally. Luckily I got the car home I had one more little hiccup but while going about 100km/h down the high way.

I took the car the following day to the mechanics and they checked it over and found the fuel filter was a bit grubby and one of the fuel lines was unhooked from its rail and sitting higher up which was thought to be the problem.

I then started driving the car to work again Monday, Wednesday then Thursday. Yet again on Thursday the traffic was stop go and the exact same thing happened it cut out while taking off from a set of traffic lights to describe it feels like a learner bunny hopping because of not enough accelerator (It would feel like it was going to go then all power is lost then feel like it is going to go and then cut out or keep hopping along). Again I was able to mange pulling the car off the road left it off for about 5 minutes then started it up idled fine and left it idling for about 10 minutes. I was able to get home again.

So both times the exact same scenario the car doesn't seem to like stop start traffic.

A couple of things that come to mind is you can hear the fuel pump sometimes it gets rather loud when stopping and going you hear it buzzing away then it gets a little louder like it went into a overdrive and pumping faster (Sounds like its pumping then it is just picking up air and spins really fast) - This is what I first thought was the problem.

But now I am also being told is it most probably is the AFM, I haven't touched the car in months it is just in the garage with a flat battery (Going to charge it) - Picking up a new AFM on Saturday from the looks the original AFM is still on the car.

No traffic / Light traffic / Highway use its fine - Long periods of stop start it gets upset.

Anyone's advice would be greatly appreciated since I am a little stressed from possibly replacing the AFM and it happens a few days down the track but also it could fix the problem.

Cheers,

Chris

      RB20 in need of modest love injection

      By GTSBoy · Posted

      As you're looking at using a Link ECU, then large injectors are not a problem. But there's not really any need to go 1000s on an RB20 unless you're planning >>600HP on E85, which would seem unlikely. There are other options for injectors. The Xspurt ones are available from a number of places and you can get them in the mid 600s and 725cc, which is probably a sensible place to be. These are all EV14 based. If you are not using the stock AFM (at all, which would be the case with a Link) then a large turbo intake pipe to suit the ATR turbos is not an obstacle, so you should use one instead of a highflow. Results will be better.

      RB20 in need of modest love injection

      By QB6SAGR · Posted

      Hey guys,  I'm after some advice and this here is the best place to get it imo. I was a member a looong time ago under another account, with a lost email address. Its nice to jump back on and see some of the same names still giving good advice.  I mothballed my car when i moved to perth in 2013, and after getting towed across the nullabor a few times it has officially done more km's on a trailer than under its own power. Now that i have started the process of tidying up and modifying it, i see the fruit available (and the fruiterers selling the produce) is different than back in the day. hence my questions, as i used to 'know' what to get and now, i'm not so sure. Engine wise the car (92 gtst) has a walbro 255, k+n, fmic, cam gears and and turbo back 3"exhaust. Wish list is a Hypergear high flow or ATR43G1, Link G4x and some newer injectors before a tune up. My goals are modest, only low 200's power wise. i know i could achieve this with less, but i've been swapping out old for new where i can. Every cooling hose has been replaced, along with mani gaskets, WP, thermostat and radiator, fuel pump and timing belt, tensioner and idler, and i rebuilt the steering rack. Regarding the injectors, the fruiterers all seem to sell what used to be considered quite large injectors. There are a lot of options for bosch 1000cc EV14's, and i would like to know if that is a suitable choice for my build. Is modern injector design good enough to run these at the low duty cycles that i likely would be? is there a downside to running a too large injector these days? or, would there be an upside to running a smaller injector at higher duty cycle? I can see that there are smaller injectors still available, but the ones i have seen specifically marketed for RB's are pretty large (see: https://golebysparts.au/collections/fuel-rail-injector-kits/products/nissan-rb20-fuel-rail-bosch-980cc-1150cc-injectors-turbosmart-fpr800-regulator-kit), and i dont know enough about them to say one not marketed for RB's would fit or not. I have searched the forums, and amongst all the posts on older tech, I did see gtsboy recommend EV14's, but no size was mentioned... again, i'm not clear on if the smaller size bosch injectors are also EV14's as they do look similar.  also, if someone can recommend a tuner familiar with RB's in the Geelong or West Melbourne area i'd appreciate it. Thanks in advance guys. Cheers, Rowdy

      R33 GTR lift points for hoist

      FWIW the depth of the groove in the rubber pad is not super essential, the blocks are rubber and squish a bit. If you are worried an angle grinder will make a deeper groove quick smart

      I mean, if you were to move the jacking points away from the original location, that is, away from the wheels and closer to the centreline of the car, then it will be more likely to overbalance and tip off the supports. Same as we talked about before. I was talking about moving for-aft. If the sill is bent outward or inward, then the car would obviously look unstraight from the outside. Hopefully that hasn't happened either. Again, you can do comparative measurements from the chassis rails to see if there is much deflection.

      Can you elaborate what you mean with your first sentence? I meant move as in the bulge kinda seemed like it got pulled "outward" meaning it got pulled down and to the side with the jacking rail itself, so the load bearing bulge now sits lower than usual and is not level with the sill on the other side of the jack point. Either that or the jacking rail just got pushed in a good bit.
