how much boost

[RB power]

hi how much boost can i safely run in by RB20det?

[CEF11E]

12 psi if you want your turbo to live 14psi if you are game

dude do a search there must be 1,000 threads about this

[RB power]

sweet im not worried about the turbo standard ones gone...

just wana know how much the engine can handle

Cheers

[lukew105]

I reckon the rb20 can handle WAy more than that...

[lukew105]

the engine can but not the turbo

never boost above one bar...and if your gonna do that make sure you have supporting mods.

yeah ive got standard internals with bolt ons

ive done turbo, exh manifold ,waste gate, fmic, bov, exh, dump pipe ,599cc injectors , 500hp fuel pump modified in take plenum ,head work ,cams and pfc

[PRO_32]

upto 22psi would be fine.

luke what do you count as supporting mods?? And are you speaking from experiance or what youve heard/Read.

[lukew105]

i have read shit loads of threads on here and that seems to be the go... supporting mods such as fmic, avcr, engine management, zorst etc. 1.5 bar is 22 psi dude

[lukew105]

what turbo you got dude?

[PRO_32]

Luke how does an AVC-R or Zorst or programmable ECU prevent a ceramic wheel of turbo delaminating??

[lukew105]

Clearly im talking about the engine dipshit

if i was talking about the turbo there is no way it could go to 1 bar

[R33Hesh]

so many dudes in here, i just realised. LOL

[RB power]

Ive got a turbonettics 60-1 turbo with a tial 44mm external

PRO_32: I also think supporting mods are a far bigger issue then the turbo itself. I had a lean out one day and melted four of the six spark plug electrodes off. Im so glad that I didnt end up with a big hole in the pistons. Fueling is way more important then a exhaust wheel falling off.

yip; its 100% in the tuning as far as boost levels go.

has anyone actually got some A/F runs of a stock ecu on a GTST r32 at 1bar?.??

My plan for mine is basically up the fuel pressure, then tune it with a safc and run 1bar on a rx7 turbo most likely.

[lukew105]

thanks dudes point proven

[lukew105]

can you interchange the rx7 turbo and is it worthwhile upgrade? i have heard little about it
