Hey guys, im building up an Rb25 which has a greddy forward facing plenum, was disconnecting stuff off my standard motor whilst trying to take it out when i thought to myself about all the damn plugs that are on the factory plenum. If im running a power fc, with the greddy plenum, what do i do with all these excess plugs? Im totally confused. Is the simple answer.....dont use them? i just thought that would look rather untidy?

Ah! I see....yes basicly you still need them, the PFC used the stock sensors whereas with some other ECU's you might have to put in their brand of sensor. Things like the AAC valve which bolts on the rear of the Plenum is not provided for on the GReddy but you still need it to control idle etc. You need to identify what each hose,plug and sensor on the stock plenum does then you can decide what to do with it on the GReddy. If you don't really know what everything in the engine bay is, what it does and how it fits in with the rest you should really do some research and find out Befor making major changes such as the plenum

    • HELP   Hey all, Is there an accelerator cable from another Nissan that can be used on the R33 GTST RB25DET with a Greddy forward facing plenum?  Thanks in advance  Rob 
    • Or do we think it was installed to give 1 bar of boost max, all day, everyday?
    • 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!
