3bar map
dark green 803
big intercooler
2.5inch exhaust without cat
on a 1991 saph 4x4?

with how many power do i need a oil breather?
thanks

Same turbo,power wise maybe 330-350 bhp.

A breather would be a good idea at that level of tune

dont go too much above 350 as your transmission wont be too happy!even at 350 i would not launch her off the lights

Stage 1 i had a Breather fitted, opened my Airbox and there were bits of oil in the corner of it..

You,ll need a Breather for the above Spec...

your injectors & 4x4 cooler is the limiting factor in your spec.

if you changed the injectors for siemens 55lbs or greys and change the intercooler for a rs500 type you'd see near 400hp with that turbo

but obviously you will need a new chip if you were to do that

and yes oil breather is recommended, i;d change it even if it wasnt tuned!

with current spec, 340-350hp is about right, but as said, transmission is the weak point beyond 350hp/350 torque

what do i need to for the near 400hp?what headgasket?and what else please.
i think i stay with those things and chage maybe 2011 to the greys injectros.
what dit you guys made on your transmisions abd how much do that cost?

a lot questionsthanks to all you guys

400 bhp it starting to get mega expensive with transmission/brakes your prob looking at 10k!you might as well go for 450 if you going for 400 in a 4x4 cossie!you will also need grp A fuel pump,maybe a multi layer head gasket,although a group A one will prob do!T34 is no longer any good for 450 need a t38,t4 or a gt30!also black seimen injectors and prob a spacer on your inlet plenum

or you can just ask kev to buy you some of the above

to much for mei think it would be fine with the 360-380hp
can the transmision handle that?

its a bit of a lottery beyond 350/350; a t34 turbo is not idle for 4x4 transmissions due to the huge boost spike in mid rev range

i would use siemens injectors over greys

pah! its all lie's, lie's i tell ya!
Its bringing them onto boost in 3rd gear thats the main killer so im told!
Mine craves 6k launches!
*toodles off to blow his box to bits now he's jinxed himself*

The man's a fooking animal lol.

i feel ashamed and the need to try harder!
I'm sure mine should of died by now, i usually destroy gearbox's in everything, cossies the only one to last a few years on me.
Maybe its secretly got a bara in!

i could kill a std gearbox on command at 380bhp

Ready, 1,2,3 BANG

WongRS

iTrader: (11)

i must have a very good box i think!
Its done lots of launches at pod (1.7 60fts, so definatly not gentle!) and loads on the road, i am really shocked by how well its lasting, maybe when its been up to you boys again in april it wont last quite so long.

What can be done at the gearbox 4x4 Do not break so easily?

KSA-Cossie

iTrader: (4)

Replace it.

evo-vlc

There are no wreaths reinforced for the interior of the gearbox?

maybe you can try at having the gears shot peened, but i dont know how much difference that will make.

its better just to get a better gearbox or replace 4x4 with 2wd
