Hello i have a 94 gsr just change piston 4 intake valve and exhaust valve. Due to no compression. well my main question is after i put everything back together and decided to test it out everything was fine, but when i hit vetec my car seem to bog down and blown out black smoke, and also it redline really slow, then when i shift to second gear it just slowly gain it rpm. i can't even feel the power when shifting.

 

learn how to type properly

 

Sorry I was kind of in a hurry.

 

Do a compression test and leakdown test. Also, did you adjust the valve lash properly?
