2003 turbo camry <<< need help

[old red]

hi everyone
i have a 2003 4 cylinder camry
i installed my own custom turbo kit
it's similar to the ZPI stage 0 kit (made for the scion tc which has the same 2AZ-FE)
the kit doesn't have an intercooler nor e-manage... yet the tc guys put up to 230whp@6psi boost

at 5 psi they get around 222whp

here's the problem:

i only got 161whp

huge disappointment

my kit is similar to the ZPI's one.. same layout too

i'm using a catless exhaust system..

what's the problem guys? why am i not getting enough power??

knowing that nothing's wrong with the clutch...


s.o.s.

Get an intercooler for starters.

hi everyone
i turbo-charged my 2003 2.4L camry
my turbo kit is similar to the ZPI's stage 0 kit (made for the scion tc which uses the same 2AZ-FE engine)
the ZPI's kit doesn't use an intercooler nor an e-manage yet it puts up to 230whp running 6 psi
i've seen dyno charts giving 221whp at 5 psi..

i've put up my own turbo kit similar to the tc's one, with same pipe layout too..

but i only got 161whp !!!!! <<<< huge disappointment

there's nothing wrong with the clutch..
i'm using a cat-less exhaust sys. (no back pressure)...

so what's wrong guys?
where's my extra 50whp???

[old red]

they get 230whp without an intercooler...

i'm way behind...
surly there's a problem other then icoming air's temp..

get some pictures up, and put up a detailed parts list of what you added (dont just say "its like so-and-so's kit")

then maybe we'll have a clue as to whats going on

how big is the turbo?

[w203]

so what are you using to tune?

this might have just a little to do with it.

There could be many reasons why you are not getting similar numbers, you need to give more details on your setup and also most of the guys on the forums like to see pics. Could be any of the following:

No tuning -(need a piggy back, management or reflashed ECU), this is usually the #1 reason for lack of power and most like with out it you will be running a LEAN condition.
No intercooler -intercoolers are an important part of a turbo setup
Turbo type - (if your turbo is not properly setup to the type of engine, you will hardly see any gains) There are thousands of turbos out there with different spec, there is a great deal of research required when a turbo kit is created by performance aftermarket companies (greddy, HKS, etc...)
Restrictive piping- For a turbo setup it is important that everything is mandrel bent. All intake/intercooler piping, turbo manifold, down pipe and exhaust.
Stock intake or exhaust?- Turbos need to breathe and exhale, both are BPU (basic performance upgrades)
Engine Compression
Pressure loss
Vacuum Leak

I'm hoping this wasn't one of those things where you hoped it was just a bolt on feature. If so, you've gotta do something fast. If you've made no changes at all to anything in your engine/exhaust/intake and your running a turbo, you're asking for a problem. Our cars are only designed to withstand about 8lbs of pressure which is almost the bare minimum that turbo's are made in, unless you had something done to make it smaller.

did you try to do a DEI (Direct Exhaust Injection?)?

I'm about to put up a BS flag...

if you want more hp, you'd probably be better off trading it in for an 08 V6... 268hp an naturally aspirated
