1jz?? What is the weak point?

[duggy]

ok guys i no 1jz's are rediculously stong standard but i was wonderin when they reach there limit what is it that usually breaks??

[1JZ.747]

idiot tuners trying to run too much boost on shitty pump fuel

i ran 37psi through a gt51r a 71mm turbo and a 100 shot of gas on a 200000 k engine and its is in perfect condition. for 80000k's it had a 65mm turbo or bigger on it, but the secret was a great tuner and race fuel.

[duggy]

how much power did u make ?

[neal]

Dude read his SIG..and the rest

[duggy]

dude i read his sig and the link it stats his times not how much power he made !

[Hash_ra23]

well my stock 1jz blew a head gasket....think it mite have been cos the previous owner didnt take care of it tho

[neal]

Mate here is link that shows how much power he makes.

[neal]

Any ways what are you p[lans for your 1jz?

chasing huge amounts of power or just reliability?

[duggy]

well its got a t78 power fc 680cc injectors custom intake and the usual supporting mods i wana no how far i should push it

[neal]

what car and drivetrain?

my guess you would be pushing close to 500 horse's with those mods.

[duggy]

its a 180sx and its got an r154 its yet to be tuned with the new turbo

[CELICASUPRA7M]

um CRIKEY! good luck getting traction! is it a drift car? be a brutal drive,
good luck with it : )

[neal]

whats it like out to drive in a light car?

[Pimpin_1JZ]

Stick to about 19/20psi on pump fuel and you should be fine.

[duggy]

yeah its yet to be driven needs a tune and also i have yet to have my question answered wat is the weak point in 1jz's
