Well All

Just wondering what boost everyone is running? And what mods have you to run that boost? What ecu/management? What Fuel?

Reason i ask is that my Sil80 has a few bits, s14 turbo, High Lift Cams, Fmic etc and im only running 0.7 (Standard). Is it advisable to leave it at this or can it be turned up to 0.9 or 1 bar?

Interesting to see what others are running. Cheers

running 0.75 bar at the mo i did have it at 1.1 with the power fc but stripped that out and dropped down the boost so run on a standard ecu for a while, will be gettin steel tubbs soon so might need some injectors too and up the boost again to about 1.2 or 1.3 :D

I'm running 1.1bar on a greddy turbo, it depends what pressure the turbo can keep
producing power at aswell, too much pressure and the turbo will only produce hot air,
which wont give anymore power!

running 1.1 bar , iridium spark plugs, uprated fuel pump, 2nd decat in, fuel cut defender.

When i take the 1st cat out then ill turn it to up 1.2.

With both cats removed it will reach as high as 1.6 , thats what the car will boost at if you dont have a restrictor ring fitted and a bost controller . But for ceramic JSpec turbos its safest at 1.2

We call this BPU (Basic Performance Upgrade) :)

At first i thought this was crazy turning it up so high, but lots of guys i know have ran BPU for years with no problems

1.2 bar gtss turbo nismo 555cc injectors z32 225 fuel pump power fc ecu and a few other bits. turning up and down boost is not a good idea if ur not adjusting fueling and ignition timing most of the above cars are mapped to that boost for the desired power.

wtf ste standard cat:eek: how why, who mapped it with all those mods and the most restrictive part of the exhaust still there,get rid of it and it will help the lag issue

in fairness how many people put the car on a ramp and look under it before it gets mapped?? its usually down to the owner to supply the info of the mods in the car ;)

The improvement the decat makes is unreal lad, you'll love it, much quicker spool up.

I bought my car totally standard, i noticed the difference every mod made, the cat back and decat went on and i couldn't believe it, even the air filter woth the custom cold air box i made. Everything else i fitted made a great difference to the car and i've a good few things left to fit yet:)

How's 1.5-1.7bar on a standard SR20 (Front mount, full exhaust system and an Apex intake) :D

Other than a bit of overheating, she was fine for 10 minute sessions round the track lol

We didnt know until it was diagnosed about a week later as it was getting checked out for the overheating problem.. Thought it was the waterpump, head gasket, blocked radiator etc etc... Never would have expected it to be caused by boost (seriously excessive boost at that lol)

why do people turn up boost as if its a tap? :rolleyes:
