As i was discussing with craig, If you've got work to do on your car and dont really have time to transport your car to a mechanic, or want it done over a weekend, or dont know what the fuuk your doing, let me know the quote and ill beat it by a considerable amount and help you out.

Cubes, i agree with the gt3540 being a '3rd gear' turbo, especially the typhoon spec 1.06 rear and also the .82 rear. Very impressive once on boost tho. I have done a little reasearch on a gcg gt3040 aswell, they are much the same to some extent.

i got a gt 30/40 highmount with a .82 and external gate on my car n they are a awesome turbo, when boost hits it hits HARD!!!

1st 2nd n 3rd gear, they arnt that laggy....

then again thats on a forged engine, i guess it'll be a bit laggy on a standard engine, but if u wanted it more reponsive put a rb25 or .63 exhaust housing on it, thats wat i had on it when it was a stock engine b4 it was blown up on the dyno....

Probably a few other reasons why it's not as laggy but how does a forged engine make the car more responsive than a standard engine?

Lighter internals? Rods/pistons etc?

if that was the case, then 1/2 psi extra boost on a car with STD internals would take care of that.

Peeps generally do a rebuild with forged pistons and aftermarket rods to be able to cope with more HP, RPM & strength.........not for better response.

I am not a fan of the 3040 on the twin cam heads they are a bastardised turbo. :)

As you say boost hits hard that = lag.

I'd prefer a much more linear turbo that comes on earlier so it doesn't feel like it hits so hard due to lag.

    • 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.
