What Is Safe Boost For Me To Run?

[Keeper]

hi guys,

i have a 89 r32 gtr with HKS 2530s, i got the turbos inspected and they are near new condition, also have pods and a 4" cat back exhaust

i installed a BLITZ sbc-r as the car was slower than my sisters pony, and is now going good running around 15psi, i had been going up to around 18psi over the weekend which hauls ass but im worried about leaning out the engine, also spiking when it got real bad with too much gain was blowing the intercooler piping off, i know i need new clamps but what should i be alright running boost wise until i can afford a SAFC or similar?

Take it to a dyno. Get them to run it up & check the AFR's. How much boost you can run will depend on the state of your fuel system & your AFM's. Just make sure it isn't running lean or it will die.

get a stand alone and you will probably need fuel reg upgrade and injectors

have a look at the rb26 turbo upgrade thread, the 2530s are pretty common

so there should be plently of proven configs and the mods needed

hmmm, would a jaycar AFM do me in the intern? i want to put new coils and tyres on before adjusting fueling

[paulr33]

sorry misread it, do you mean the jaycar DFA thing?

its a comprimise much like the safc, same logic and functionality

can afford a rebuild

if yes? go for it

if no? do it properly and get it tuned safely

crap misread the 2530s bit

i would be getting it tuned with a real ecu in the first place

what boost is boost if its not tuned properly, its most likely unsafe

Do it right or not at all!!!

You will regret it otherwise.

ECU re-map or upgrade and head to the dyno.

haha

what about just day to day driving, wold 14psi be safe? until i get the ecu and tune?

im running 1bar on mine.. upgraded hi flows. but i got a mines ecu..

but dont assume. get it checked out before u pop something. as we all know rb26 aint cheap to rebuild
