Let me know what you guys think, suggestions for making it better are welcome... I think im gonna take some sand paper to the hole thing to clean it up alot.









I am not putting the spacer in.

 

so how did you do it? doesnt look too bad, is this going to be on a FI setup?

 

its a NA high compression big cam set up. I just grindied it all down ported it out takin out the butterflys and spacer makin the plenum smaller.

 

i was debating whether or not to do this on my FI setup, but then again im only stock block with 6lbs

 

I did this on a gsr with a stock bottom end. The throttle response and low end wasnt great. The top end screamed though. With your higher compression you may not have a problem, but your low end will usually suffer anytime you increase the amount of airflow that much.
