r154 box alone is 1600, then you need clutch, pedels ect so 3k should do it


think its around the 13/14 psi mark on them best to get electronic boost cut defender, although after installing safc on mine it stopped the boost cut, thats the vvti so not sure if there the same


only 1 way to find out ha ha

yeah nick had a safc on it & runnng 17psi so they must have a boost cut defender.

not real keen to do safc again personally, best gains come from ignition maps.


whats availiable as far as flash tuning these ecus's?


whats the stock map sensor 3bar?


dont spose you know what standard suspension adjustments these have? (the castor rods look adjustable but im not sure, assume no standard camber adjustment?

car needs a wheel aligment

whats next is replacing these plugs (with 7's or 8's) dropping the gap down a bit (was 0.8mm & 6 range plugs as thats what was in there) & getting it tuned again for 16 or 17psi.


now thats its at least tuned/checked i might take it down the strip


oh yeah still needs a wheel alignment & more rear rubber so probably a way off seeingif it will crack a 13



not sure on the cruise, would like too, so will see.

i only intended to run 15psi so i rekon 98 is not needed for such a low boost level (others run 17+psi reliably thru the stock twins tho)


because of the crap plugs its running (6's @ 0.8 gap), we couldnt increase the boost much from 12psi.


if i keep the car i will put some 7's or 8's in there with a 0.55 gap & then retune it for 15psi (still on 95).


it is tempting to run it on 98 @ 17psi & pick up another 30rwhp or so, but the car hammers as it is now.


would piss all over a stock evo now even on 3/4 throttle lol.


so its quite good having a turbo car this fast & not having to buy 98 :)


i have a chart with AFR's as well btw
