your problem is you have a shitty management system. your either running hella rich or lean in boost.
does it bog down in boost do you feel a change at all when you spool?


I just realized... are these stock injectors?

lol, welcome to a turbocharged Honda

TURBO LS HATCH

yes stock injectors and no i dont feel a change when the turbo spools i did but when i teed all that vac to different places i stoped feeling the turbo all togeather

if the boost gauge reads 7psi and stays there then you are getting boost
if the boost gauge is teed off at the fpr then the engine is seeing boost, if before the throttle body, check your piping and connections for boost leak

if your wastegate was stuck open you would not see boost unless it was a small leak. remove wastegate and check the spring or rev the engine and feel for exhaust gas out of the wg dump tube (with paper or something)


as for fuel:
are u running the FMU?
i would get rid of that and run the AFC hack or standalone
that would solve your fuel issues

i found out my problem for no boost the wastegate was stuck open but now it leans out and it reads like 15psi but i know its not 15psi now what could be the problem

How do you know it's not 15psi? your boost gauge isn't going to read 15psi unless it's actually seeing 15psi....Is your wastegate hooked up properly? what kind is it?

TURBO LS HATCH

i have the wastegate that comes with it the one that sux i forgot the name

So where is the inline fuel pump that is supplied in the Drag kit?

It is neccesary!

*EDIT* Dont "T" off of the PCV. You will draw oil vapor into your bov/wastegate.

turbod16y8

need to know too im not boosting also

TURBO LS HATCH

this goes to 93lscivic u ran 12.71 with street tires what do u have for internals or what ecu r u runing and whats the most boost u can run on a stock ls i mean stock with turbo kit and is it possible to run like 8psi and then a 35 shot NOS dryshot before the intercooler or should i just run more boost like 11psi

93LSivic

Dude, before you start runnin 8 psi and a 35 shot I would seriously suggest you get the proper fuel managment. The FMU MUST be used in conjunction with the inline fuel pump supplied to you with the drag kit even though you are using the aftermarket intank pump.
At that time the motor was completly stock w/ turbo. With the exception on hondata and 550 injectors. You will need larger injectors...i would suggest dsm 440's with the afc hack, this is the cheapest and works very well. As far as boost, its all about the tuning, however stock pistons suck *** and the ring lands are known to crack if they see any signs of detonation.
My hondata is for sale by the way.
