i think theres a possible leak before or after the adapter plate. i checked it out yesterday... the spring works fine for me. atleast i don't have to worry about wastegate failure. the exhaust is 2 1/4 inch so yea...

When you start getting 7-8 acceptably quick, but need 15-20 pronto - water injection. All that expanding steam, just like a turbine at the local power plant.

How to get 4 to 4.5 psi quicker? *sob*

i think i am having the same problem, i get full spool at 4500rpms with a 42/48 air research turbo on a b18b. i have heard those things being able to spool up as quick as 2400rpms. could it be how i have my mbc routed?

What size charge piping are yah using?

run open downpipe for one day, it will give you an idea of how restrictive your exhaust is being

personally i see 5psi by 3k with a 14b and big 2.5" charge pipes, 8" intercooler, and 2.5" turbo-back exhaust, no cat.

but i also use the dsm internal wastegate.

Another thing? is this car daily driven or just for fun
You dont wanna be fully spooled just driving around crusing do you??
It does sound slow but not that bad IMO

my car is daily driven... i fix the leak i had. its starts to spool around 3? and hit full boost a 3500. better then before but car still runs like ---- seeing boost...need more check valves... i hope the chip and the conversion harness is coming in today/soon... ------- fmu... hey i can beat my cousin's is300 (has hks hi-power and some intake) so does that mean i'm running low 15's right now? cuz is300 are suppose to be around 15.3 stock...

Why not just use a smaller exhaust hosuing.
A lot of guys just make the entry into the turbo smaller.
Instant results.

I would try smaller charge piping
My last set up was a T3 .42/.48
2.5 TB-> IC
and about 2.0 to 2.25 IC-> Turbo

my new set up im trying 2.25 piping
