I Have standard turbo and run big front mount no plenum....but sumtimes run high boost 11 psi ..normally i run on 6 psi....but want to know what should i do to the head or engine or anything on that matter to acomadate for the high boost that i run so it can run safely and not do damage THANX!!and on a budget atm too..please help

computer injectors and fuel pump

ohh sounds good ..what sort of computer though? cause it runs fine but jus scared im gonna blow the head or sumthing thats y i thought if there was sumthing i could strengthen then yeh id do it

clobrese, please use the search function of the forum. These types of questions get asked regularly.

11psi high boost? that aint real high dawg

l'm running 12psi then goes back to 10psi with standard injectors and head, afr of 11 and have no problems according to the dyno, just running rich and l will adjust that from the afm whilst on the dyno.

t3 max is 14psi 11 with cooler is sweet just make sure your radiator is in good condition and flows good.. should be good just get a dyno tune to get it running nicely

max 14psi is a load of crap, my gold vlt i just sold only had 3" turbo back exhaust, and gkteck cooler kit, 15.8psi wasnt an issue.

I thought if its on the dyno and there is no pinging and afr's are good it should be ok?

the turbos dont max out on 14psi the thing is that the standard turbo computer injectors ect cant feed any more fuel then around 12-14 psi and it gets dangerous, you get pinging it leans out ect ect 11 psi if its all factory turbo computer 3ta or 3tm with turbo injectors (brown top) will be fine aslong as timing isnt to far advanced ect

the standard wheels in the factory t3 werent designed to cope wih continuos 14psi plus boosts, as stone racing also pointed out the comp/injectors arent capable either. You can run 20psi through a standard t3 but the compressor map will show it is out of its efficiency range and you are spinning it up for no real gains. Also its only a matter of time before the wheel shatters.

cheap fast reliable pick two.. surely you've read that before also presuming u are running an orig turbo engine with std turbo, vlt ecu and vlt injectors. 12psi just make sure u run 98 and its not pinging if converted with std gear try keep it below 10. if converted and still na ecu and injectors 6psi if converted and running bigger turbo like ebay t70 whilst still on na ecu and injectors 4psi.

fuuk thanx boys thats helps heaps...apreciated sik ****s !! Some original photos have not been recovered yet.

Anyway I got a t4 wheel whats the safest and most effecient psi to run providing my ecu, fuel stuff, inter, etc is up to scratch. I was hoping to have a daily 9 and 15 psi on the strip?!?

i got bosh 044 haltech e6x siemens 550cc injectors t3 hiflow on 20psi making 280rwkw all day every day

What are the wheels and front housing? also what comp? My old turbo factory turbo with t4 fronr hosuing amd the highest flowing wheels that would fit, was maximg out my fuel system at only 11-12psi and 225rwkw And it was most efficemt at 18psi

is that question for me

or me lol. Didn't realise they could spin up to that fast efficiently!!

18psi spiking to 22psi, stock R31 fuel pump and VLT injectors with remapped stock ECU = cracked ringlands and blown headgasket :P after a few months.. I'd know Some original photos have not been recovered yet.

got acl pistons and rings with mls head gasket, no probs ere lol!
