ok… turbo ca18et

at first… the car woudln’t even hold a boost…  
but after I changed the fuel filter… it’ll hold a boost

but not the max boost

I’ll try to explain

ok my boost gauge is like this… **-5 | 0 | +5**  
simple one. .  
before. the filter change… it would go to the half way mark btw 0 and +5  
and the car would stall and restart as it is moving

well after the fuel filter change… my car can hold the boost a the same half way mark now

but… if I try to floor the gas pedal (open throttle) as the boost goes beyond the half way mark on the boost gauge… about 4000 rpms…

the car stalls… then restarts b/c the car is moving  
so basically I can’t even get to the +5 boost

does anyone ever had this problem w/ a turbo car?

the car doens’t have a BOV in it… , just straight from the turbo to the intake…

thanks

ed

No BOV and No Intercooler?

What is the gauge measured in PSI?

sounds like you might need a fuel pump, although a walburo is not needed for a stock ca application.  
my car also did that right after i swapped my engine because vacume was not set up right.

is it actually stalling or sputtering?  
if its sputtering it could be a misfire …ie: plugs arent gapped properly.(to wide)

do a cold compression test and check out your turbo, maybe your idiotic lack of a BOV has blown your turbo force feeding your engine shrapnel. and just because you’re building boost, doesn’t mean your turbo isn’t fried.

do that before going out and buying a new pump you don’t necessarily need.
