Honestly i would expect better from a mod but come on the guy asked a pretty simple question.

What is the recommended spark plug gap for the RB25DE is it really that hard to answer.

Maybe he wants to change plugs who knows his post didn't really leave mush for detail but he did ask what gap he should run.

For the record i have NGK BCPR6ES plugs i would also like to know what gap i should be using

well you can expect all you want, but i asked for very simple information in order to give him a better answer. he asked if he should gap the plugs (in other words, should he alter the gap). i simply wanted to know what gap he was running so i could give him an accurate answer. you said yourself his post didn't have much detail, so why be upset when i ask for more?

if a mod asking for info is bad form in your eyes then you are going to be regularly dissapointed on this forum. since this is a question that has been, believe it or not, covered hundreds of times, most mods would've simply said "use the search function" or simply not posted at all.

to answer your question about what gap you should be running, stock gap is 1.1mm, but anything between 0.6mm and 1.1mm is perfectly fine. the bigger gap the better, but sometimes you need to reduce the gap below 1.1mm to make up for weak coilpacks.

      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!

      Chris' Toyota Mark ii JZX110

      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.
