Hey all,

first off i'd like to say, begin a new member here, that this site is definatly a huge help for rb newbies like me at getting to know your stuff. I think its cool that everyone here can share their advice and help out others.

ok now to my problem.

I got a 1990 R32 GTS-t Rb20Det Auto Sedan, only mod's being a chipped ECU (bought with it) and a Blitz POD Air Filter, It doesnt have a BOV. had it for about 4 months and most things running/working fine. Had to replace Water pump and radiator about 3 weeks ago, looked like a seized bearing in the water pump that caused that problem. any way all fixed untill 1 week later when started running rich, chewing fuel and dumping a heap out the exhaust untill running to work oneday she just cut power and stalled all together. This was after about 30mins driving sitting on 80-100ks most of the way. Could'nt even get it running again till after a week of tinkering with injectors, the rail and fuel pumps we got it ideling. Now whenever we give her a stab it stalls when backing off as the rev's fall.

On 1st thought we thought we had stuffed the timeing when changing the water pump, then looked at the injectors but they seem to be ok. after looking through a few forums we thought the AFM was bugged but just got word back that its all working good, we have checked pipeing for leaks/cracks. It's still over fueling and stalling and my brother and I are stuffed for answers and my cars been out of action for 3 weeks now.

Any input, hints, tips, answers... new engines would be greatly appriciated

naa it wasnt the head gasket, that was one of the first things we checked :) thanx for your idea though. Im not blowing any white smoke out the back so dont think its water. I am blowing/backfireing thick black smoke. raw fuel? expensive way to re-paint the workshop walls!

I'v just got it tow'd again! to a Skyline specialist. (tow bill is well into the hundreds now) hopefully they can find what's wrong within the next few days and I get it for the weekend. will keep you all posted as im sure this has happened to someone else.

worm.. if I had compresion lockup i wouldnt be able to wind over and all my valves would be bent.. thank god it wasnt that serious. It's been Fixed!

Turned out to be the fuel pressure requlator and the cam angle sensor was shagged. Luckily the guy had some there and everything was under $300. I get it back tomorrow.

thanx worm and youngcodger for your input/concern/random comments...

    • From what I've seen and experienced first hand with those powder extinguishers, they're good to use to break a window and escape the car, and half the time then do f**k all to stop a fire. You just need much more than 1KG worth of powder. Not to mention, half the time it's an engine bay fire, and you can't easily, and do not want to completely open the bonnet, so you're left pretending to be an American Infantry... Spray and Pray baby!   And then 100% that shit is really destructive afterwards!   Realistically, those little ones at a race track might help you keep the fire from growing and give the fire marshal / truck a chance to actually get to you with their multiple large bottles.   For a road car, these days, prepare to deboard as quickly as humanly possible, and move to safety. Allow insurance to fix replace it (unless it's like a rare classic etc, then do nearly everything possible to save it!) Keep the little extinguisher with you to help protect other things around you from burning while you stand there singing "How can we sleep while our beds are burning?"   Secondly, powder extinguishers I freaking hate for indoor use, (this isn't really relevant to a car) as you will get a powder fog around you, and it can be disorientating.   When I did fire training when at BlueScope Steel, they have (had?) their own fire brigade on site. We did all the training, and at the end we were told, "If it's an indoor fire, and you need to use a powder extinguisher, we as the fire brigade would rather you just exit the building, you're more likely to get lost in the smoke and powder fog than do much help, so just GTFO" And pretty much that was what they said for most other fires too, grab extinguisher, if it's much more than paper in a bin fire, use extinguisher to get you and others out of the building to safety...   Part of me wishes when my Skyline caught alight many moons ago, I let insurance sort it out, instead of putting the fire out... part of me now says "But I've saved a classic before it was a classic!"
    • Hi all,  I have a older model of the Greddy Front facing intake on an RB25DET NEO Head. I've bought aeroflows fuel rail and injector kit (1000cc Bosche injectors) and I'm unsure if the fitment is correct. The injector o-rings fit in the intake hole but it's not snug. I can very easily rotate the injectors even when the fuel rail is mounted. The kit also came with multiple adaptors, they dont make it any more snug and using them raises the injectors up and i cant mount the fuel rail. I hope this makes sense I've asses a few photos.    Thanks so much guys. 
    • So, to run the 4g aerials to the booster, I had to get access to the rear bulkhead....bit of a mission. Hot tip, don't offer to help change the rear shocks for a mate with a v37.... Remove seat base, 2 clips that slide forward to release it the it lifts straight out Fold down rear seat (pull in from boot) The side bolster of the rear seat is not connected to the middle parts that fold. To remove unbolt at the bottom bolt then push it up off the top hook Then there is a plastic surround behind the seat back, 2 pop out clips, 2 bastard clips, some swearing at it is out Pop the rear seat latch surround off Remove door surround lower trim then side trim  Remove c pillar trim - 4 clips, pull inwards not forwards Remove metal brace - 5 bolts 1 nut Then you have got to the rear strut top...what a pain!
    • If you really want squish back, you can have it put on the piston (at least to some extent).
    • Impressive. He's very very smooth.
