What as all done to this? 12 PSI on the Stick twins? Bout to get mine fired up here in the next week or two...!

[jonnyfury]

no big single.

[ssqv65]

other than big single upgrade and exhaust... what other upgrades you have?

[jonnyfury]

that car is long gone. it had a power fc standalone and a decent fuel system. thats pretty much it.

[nitrousboy0311]

What happened to it? crash? stolen? sold for new car? if so what kind of car do you drive now?

[jonnyfury]

Sold it long ago. I have another supra in the works.

boys boys, easy way to discuss this like men, guy #1 asks 8000rpm really i thought it was 7250rpm on the 1jzgte guy #2 nope its 8000 and because I'm so knowledgeable i have found out that the single turbo VVT-i 1jzgte has a redline of 8000rpm and the twin turbo 1jzgte has a 7250rpm guy #1 gee thanks i didnt know that...fucking kids

[xSwordx]

you dont even have a 1jz so what the fuck are you telling me this bs?

how will 4th gear have a different redline than any other gear?

stock ecu 1jz redline is 7250

[mkIIIsupras]

@bloodseedrums 12 psi from the stock twins is not the same as 12psi from a big snail. bigger turbos are more efficient at lower psi levels.

@xSwordx Who say the the 4th has a different redline than the other gears. what, the redline that is painted on the gauge moves, what a idiot, if anything the 4th gear could be setup to shift quicker, but not redline at a different rpm.

[dafrankfuter]

Love it! Can you give me the full specs on that t67? I have a 1jz in a 260z with t78 it's a pig turbo is way to big .

[ghettodriftmonkey1]

@xXNukeMeXx well said.

[crzygutrsnobrdr]

@l3eals it depends on what cams you put it...264,272,288 etc. Its stock redline unless you change it in the ecu will still be 7250. Unless you take off the fuel cut even if you put different cams in there, it would still be 7250.

@xJ3R3M14Hx lololololololololololololololo­lolololllollololololololololol­ololol (farted a little) lolololololololololo

[l3eals]

putting cams in a 1jz raises a the redline to about 8000.

[DanDanNissanMan]

nice, wheel spin!

[2013645]

@anthonyrb20 also he's obviously not wasting rev when he's pulling that hard well up to his stock fuel cut rev (7250rpm)

[2013645]

@anthonyrb20 i'm assuming your on a bpu set up, in that case your stock twins start running out of breath around 5500 and are obsolete at 6500, once you go big single your boost map changes completely and depending on the turbo might only be reaching peak efficiency at 6 grand. He is running a big single with power fc which allows him to play with ignition timing and fuel feed to prolong the effectiveness of his cam (which from what he has said is stock) which means ability to rev higher
