hi i have a gsr it runs good but once i hit vtec it engages but feels like its boging out what can it be i already check me timming its good

 

You don't feel it or it's bogging out? Which is it? Any CELs? If you don't want your thread locked you need to state all the car details.

 

B18C1's aren't known for having a rough transition into vtec last I remember.

Do you want the transition to be rough?

Your thread title and 1st post seem to say two totally different things. What is it really doing?

 

It's supposed to be engage smooth.


Check the vtec solenoid gaskets. Clean it/replace the gaskets.

Also, when is the last time the car has had a tune up? Did you check the ignition timing?

 

when it kicks in its loud but it starts to bog the motor is fully rebuild the vtec seloniod gasket it clean

 

is it tuned/chipped ecu?

Did you check the ignition timing?

Any cel's?

 

check dizzy timing.

 

what ecu? chipped?

 

it a stock p28 no its not tunned i also tried my friends ecu and it did it worser and his is a p28 chipped and no cel's i the dizzy is at the digress it sopose to be at

 

How do you have a P28, a SINGLE CAM ECU, running a GSR and not have it chipped and tuned? Worser is not a word.

 

You need to get the ecu chipped, and tuned.

A base map, made for your specific engine/mods will do for a little for a while, if you can't afford to have it done now.
However, you do need to have it dyno tuned.
