the imported stuff, the put big dollars into reseach 2 make there products the best ( no restriction ) an thats whats on my mind... EG if the local 1 costs $400 an will give me 15kws and the imported 1 costs $600 an it gives me 18kws i would rather pay the the $200 diffrents

Ok, I'll put it to you like this. I was running 190kw at the rear, I had a retune and put out 205kw at the rear. I drive the car ALL the time and could not feel ANY difference. Now the difference in dump pipes is so minimal except for maybe top end and you'd probably find as you stated that it's under 10kw difference. I know what I'd be doing :thumbsup:

Just some cost saving tips, not trying to put you off. I had the same drama's and I've used ALL top name Japanese parts on my car eg. Nismo, ARC, Apexi etc but on the dump pipes I was reading a lot of info and found it to be of little concern. Is your car GTR or GTS-T? ;)

Ah sorry just noticed it was GTR, I've heard some interesting info about the dump pipes on GTR's and that unless your running high end mods that there is little gain to be had for $$ value, better of with front pipes etc but it's worth doing a search on!

ive seen in books my engine (rb26dett) punch out 400kws with stock internals....but when i speak to some tunners they say replace the internals at about 320kws/ 340kws

so i want to get info on tunning

    • 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!
