So while changing my rad and hoses and installing a greddy style plenum I noticed my clutch fan is cracked in 15-20 spots at least.

I don't want to run the risk of it flying apart and have decided to install thermos. Wiring isnt a problem at all but i was told to use ef/el falcon fans.

I have changed the way the high pressure power steering line is run to get that out of the way but the fan motor is way to close to the belts and pulleys for my liking.

Wondering if maybe ford mondeo's are a better option or any other tips and tricks to make them fit?

Photos if possible would be great.

Thanks guys

The Falcon fan/shroud assembly needs to be trimmed by about 25mm, and some simple angle brackets made to mount it to the radiator. Not an exceedingly hard job for any competent sheet metal fabricator. You'll end up with about 10-15mm clearance between the fan motor and harmonic balancer, enough to get it all fitted in there nicely.

The pulley, or the way the high pressure line runs forward? I re-jigged that hard line and everything worked out nicely. The front most section of the harmonic balancer is what drives the power steering, so they are in the same plane. If one is a cleanance problem, then so is the other. Either way, sounds like you're on the right track. Modify the shroud, wire up the fans and alter the power steering line; away you go.

I can't say at this stage whether running thermos is warranted, or even better than the OE mechanical fan. It certainly works, but the sheer electrical drain means the alternator works harder so you still get parasitic losses to counteract much of the gain through deleting the mechanical fan.

No doubt there are plenty of opinions out there.

      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.
