well , you know reading this forum and you would think that money grows on trees . we ( my son and myself) have just gone through the process of fitting a new system on the 31 3" crush bent system with just a muffler on the rear , would be a little loud for the street but it wont be so tuff and you could add one to quiet it down, The thing being this car produces 530Hp at the wheels and it doesn't make any dam difference if it is mandrel bent or not the gas still gets out. $400 for the tailor made system and it will last longer than you are going to have the car for anyway .

Lol.

The gas still gets out the stock exhaust doesn't it,

Where do you draw the line?

Crushing the pipe reduces the flow. That's a fact. Why have manufacturers of new cars stopped using crush bent exhausts? Cos they are shit.

If your crush bent exhaust is working for you good on ya.

Well I have been building race cars for the last 40 odd years and have a little experience with exhaust systems , do you know how the gas flow goes down the pipe , doesn't go anywhere near the outside of the pipe but about 3/5 mm in, due to turbulence , crushed or mandrel for you guys unless you race the bloody thing wont have a slight bit of difference and I have proved it.

Unless you put a mandrel system on and compare it you haven't proved anything. And I don't buy your "only down the middle" theory.

Anyway, rather than an Internet argument just take it that I disagree.

Like I said it's great it worked so well for you.

    • 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.
