1992 civic hatchback si
b19c1 swap the normal stuff intake header full exhaust
the car is gutted no rear interior no plastics carbon fiber rear gate
just wondering if this is normal to smell that in the car because it's gutted im going to go have it looked at for leaks just wanted to know if anyone has a opinion . thank you

 

Check for an exhaust leak.

 

That was my first guess just never owned a gutted out Honda thought maybe due to the lack of interior and the carbon fiber gate might just be the was it is ... thanks

 

Is the Catalytic converter gutted? I found that without a catalytic converter I was getting exhaust smell in the car a lot, while sedan's and coupes never seemed to have a problem? Once I installed a Catalytic Converter, my exhaust smells went away.

Seems the hatch rolls a pillow of air behind it that traps exhaust gases. When you stop that pillow flows over the car towards the front and gets picked up by the fresh air intake and the sun roof/moon roof and front windows when open.

If you don't find any leaks but have a test pipe, this might be your issue.

 

"b19c1" so 83mm bore ? either way check that the exhaust manifold bolts are tight I forgot to to tighten mine once and I had a yucky smell in the car.

 

Also check to see if all your firewall grommets are seal or if any are missing

 

Thanks I will try all the ideas. . I'm going to go to speed factory to get it checked
