Help With Rb20Det On The Gold Coast

Hello all.

Need a little help with my rb20 powered calais.

the previous owner could not get it running right after countless attempts. I have had the car for only a couple of days and have had no success either.
I have checked all the spark plugs, coils, loom and not yet found anything that could help the problem.

The problem is. Difficult to get the car to idle when warm. Idles fine when cold, sometimes it hovers around maybe 200 rpm won initial start but it comes to life and sits at a higher decent idle after about 10 seconds. If I pump the gas once or twice it gets to idle straight away, just needs a little help to pick it up.

as the tacho is busted, i can only give approximate revs. At around 3500 rpm if i try and put my foot down, it will spit and fart and cough all they way through the gear. I can not see or hear any air leaks. The only mods I can see are big FMIC , decent exhaust manifold, and a T04e turbo(lol).

It just does not want to rev freely.

What I am asking. Is if anybody in the Gold Coast area, would be willing to help me out with these problems. I have never owned an RB, yet have had many powerful cars, so I am not an idiot, just new to the RB. If someone could come around and point out specific problem areas on the RB, and give me a hand to try and find this problem, I would be greatly appreciative.

I would take it to a shop, But I am physically disabled and in no way can afford a shop to look it over.

I am happy to supply the beers to whomever comes around to help me out.

Im not a rapist, murderer, theif or low life. I have no intention of dicking anyone around. I simply want some help on my car so that I can have a car again.

Kind Regards,
Clucky-7

I have recently changed the afm that was on the car to another one. both standard afm's. it seemed to have somewhat eased the running of the engine, however still, as soon as i see boost, or put my foot down, it does not run right. There is still something wrong. I am only running 5 psi of boost, so i know it is not overboosting.

However, that brings up another thing i want to ask. Where are most people getting a reference signalfor a boost gauge from? Currently I am running one from the intake manifold. There are two on there, I am running the boost gauge off of the highest one. the one underneath has 5 cm's of pipe and is blocked off with a screw. The nipple my gauge is connected to, has a t-piece on it, one line going straight to the boost gauge, and the other side of the boost tee is blocked off with a screw aswell.

Can somebody please shed some light on where these two nipples are meant to be connected to, or what they are meant to have connected to them. Aswell as informing me of where you are getting your reference signal on your RB20DET.

Thank you in advance.

Kind Regards,

      It's unfortunate what Tomei USA has done to Tomei's name in general. I'm very weary of ordering parts from them now. I only order direct from a Japanse source (e.g Nengun). At least their logos are different, so you end up knowing what you have.

      DeAgostini 1/8 scale BNR32 Nissan Skyline GT-R Nismo

      By Rezz · Posted

      Update Issues 5 (plus #4) - 10 After making a claim about issue #4's missing part, DeAgostini Japan sent a whole new issue #4 and it arrived about 2 weeks after that. That was back in early March. It took another 4 weeks to receive issues 5 - 13 though. This update is for issues 5 - 10. Ove the 5 issues the front left suspension and most of the engine have been completed. The quality of the castings and fit of the parts is quite good, it seems better than DeAgostini's BNR34 Skyline GT-R from the Fast & Furious 2 movie, which (to me anyway) doesn't seem to have as tight tolerances or quite as accurate castings.  Each issue has a lot of info about the 1989 - 1993 Skyline range and other Nissan models from that era, but the focus is on the BNR32 Skyline GT-R Nismo and the various racing it did in Japan, Europe (Spa 24hrs) and of course Australia. I've included some text translated with Google Lens in some photos and will add to them if there's anything worth including.

      If it's for a SR20, make sure it's not the American Poncams, might as well call them Poocams. Had a set in a friend's car, all scuffed up after a few track days. Like the metallurgy Tomei USA used is junk. Went back to JDM OG Tomei Poncams, no issues till now.   Tomei USA is not the real OG Tomei.   Random rant over, fk the US of A, bunch of c u n t s.

      Most of the industry in North America either runs on Siemens or Allen Bradley. I have two redundant S7-1500's on my desk right next to me for simulation. Siemens has been losing ground though since Stuxnet, as cybersecurity is a big thing. In my line of work that is federally regulated, you must by law have a cybersecurity management program in place and its audited and inspected every so often.  I work with Emerson PLC's daily (RX3i's) and have done large biogas/refinery projects with their DCS's. Their PLC's are somewhat OK minus the way they do PLC redundancy (You have to download on both PLC's separately every time you make a change )  As for their DCS's... you'll be limited financially first before anything else stops you. Costs are exorbiant at roughly 10x what it would cost you to do with any other system (e.g AB PAC).  1990's, those suckers are brand new haha! Kraft-Heinz (An old client when I use to work for an ESP) still runs Siemens TI505 PLC's from the mid 80's. Ohh how I don't miss working with those... you could only do a certain number of online downloads until it's "Change" buffer would be full and you would then need to go offline to do a full download. There was no warning of when this was coming up and it generally would happen when you would go in at 2am to make changes before production -_-.
