ok i have a question......... i was reading about the ka24de and i found out somethng very interesting. I found out that there at like little butterflys in the lower intake manifold, is this true. If it is why the hell would nissan put them there. And should i take them out.......do you think it would make a difference.

 

Yes, it is true about the butterflys. I think they are there for low end throttle or something. If u go to ********** then go to faq they talk about their removal. It only gives like 6hp and is a pain in the a** to remove

 

yeah thats what i thought........i was trying to mess arround with my intake manifold the other day because i have a vacuum leak somewhere and i cant find it.....but i was going to pull the lower intake manifold off and it is kinda a pain in the *** so i stopped. but thanks alot i just wanted to make sure.

 

Well, your vacuum problem could be wiht the pvc valve line. but that is an even bigger pain in the a** to deal with since it is behind the alternator. Good luck with that

 

hey i found my vacuum leak it was on of the bolts for the EGR valve and now it runs so so so nice but thanks alot man.

 

Glad to hear it is running. I'm glad I was able to help
