Boost Cut On A Rb20det

[polishboi]

Hey guys i just got a r32 skyline 1992 has done 141k km mods are a r34 Neo turbo FMIC 3" Front pipe to a 3.5" exhaust (no cat) standard injectors and fuel pump. Running stock boost at the moment was wondering what boost would be safe to run on this setup and at what boost does Boost cut tend to kick in!

People say that on the r32 it seems to be around 14 psi. but it depends on the car and on the mods.

There isn't really a safe boost. any increase over stock increases the chance of the cermaic turbine getting spat out.

I'd make sure that i had the usual mods like fuel pump, fmic, exhaust, highflow cat etc before I even thought of turning up the boost. make sure you've got a gauge etc.

If the car was mine, i'd run 12-13 psi, but that's just me.

hope that helps. have a search in the rb20 results thread - it'll give you an idea.

That may be 14psi through the standard turbo, the R34 turbo is going to flow more than the standard. Essentially it means you can get the same power as the stock but with less boost.. so if you're running stock 32 boost (10psi) you're already flowing more than if you were running 10psi through the standard turbo.
