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,

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit?

      What should I do next to hold the head on

      By Gareth87 · Posted

      Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!

      I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!

      I don't care for these at all, but at least the underside looks straight and not rusty. A good basis for a long life. Many cars from Japan have been lifted with forklifts and f**ked almost irrepairably.

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      Yes, but it's not dumb or dodgy. You can build a perfectly good boost controller from a pressure reg, a relief valve (looks same same as a reg if all from Norgren or SMC, for example) and a check valve. I ran one for years. Only superceded with  EBC because I could get one for cheaps and wanted finer control.   THis mod is certainly not a sketchy boost mod, provided the boost is kept below the "spin to death" threshold of the turbos.
