Yeah gotta get rid of it. Did have a k&n but it rubbed on the bonnet so think I'll just get an apexi. Yeah once my consult arrives I will check timing on start up. Will try and start this arve to see if starts up straight away like yesterday

My CAS was weird. Everything seemed fine but I got random knock every now and then and it was making alot of noise. Pulled it out and you could barely spin it. Car has run much nicer with the new CAS. Having said that, the old one never caused any idle issues but if you can borrow another one its something else you can rule out.

Make sure you set base timing and probably do an ecu reset as well

Just a few things...

Everyone of my RB20s (3 in total) all had a wierd surge/hesitation when coming on boost for the first time when cold - I believe one person had found a fix for it... I seem to think it was CEFFIE (or some similar user id - the guy that does the chips for the rb20 ecus)

but once they are warmish - that issue goes away.

Pod filter - I had a blitz pod filter which mounts on to the AFM - on the RB20, this ALWAYS surged and kinda jerked around.

I then used a different pod on an extension pipe and it worked fine.

see here..

Also have awesome sauce box for it..

you can have them cheap cheap if you like.

Yeah will check first Cal and then I might grab it off ya if it's the CAS. It started perfect yesterday before I drove it to site. So will try this arve and see. Haha I just finished making a box bugger. So nah thanks for the offer though. Will just go a nice apexi power funnel I think nice and stubby.

My point about the filter was having a free flowing pod right against the afm may be causing the issue as air comes in from all directions.

having a slight extension pipe so the air smoothes out before hitting the AFM might help.

Also, if you have the mesh off the front of the AFM (which helps smooth out air flow) it will also cause problems.

ive also got the same cold start issue as you. will idle rough for a few seconds in the morning and struggle to build oil pressure unless i give it a rev. it doesnt have any other sutters or problems and isnt hard to start. its a 33 n/a . hope you find a solution

Rb20 on stock ecu will feel sluggish until water temp hits 65deg. Baby it until over that temperature. It retards the timing until 65deg. I'll have a look tomorrow morning at the ignition timing value for your own info.

Past week I have been getting rough idle and dropping to the point of nearly stalling. no new mods to cause this change. Cleaned the aac and Iacv and problem still there. I wonder if it could be linked to cold start issue (which I have had prior to this idle issue)

Will clean afm and see if that's fixed at least one problem...

what price u looking at for the filter/pipe set up?

I dunno.. 50 bucks?

I've also got a consult port cable and screen thingy I'd sell..

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