Hello, i'am having problems with my primary spool up, i never get full boost on the primary till after 4500 when the secondary and the primary are spooling together. in neutral no matter how i high i rev i never make more than 0psi, it almost feels as if the car is non-sequential, but it is stock sequential. the mods i have are downpipe, pfs catback,high flow cat, apex pfc, intake, thanx in advance

 

What boost do you make when you drive the car? That is what matters, not what you get revving the car in neutral.

Are you having a problem with boost when you drive the car, or is it just not doing what you think it should when you rev in neutral?

i dont think its possible to make boost with the stock ones in netural. Do a 3rd gear pull and see what you get.

 

While i'm driving i get 10psi at 4500rpm and hold it to redline, In neutral i make zero boost no matter where i rev to, ive heard in neutral i should be able to make atleast 4psi

 

Well, I get a few psi if I rev it hard in while not in gear, but not revving it easy. If yu're getting 10 psi before and after transition who cares? You say you get 10psi at 4500...what do you get, say at 3500 at WOT? You should be getting about 10 psi there too.

yea thats the problem if i punch it before 4500rpm i get maybe 2psi, then after 4500 i get 10psi

 

You should check bureau_c's thread on a similar problem:

Thanx yea his situation sounds just like me except my ccv valve is always shut before 4500rpm, now i'am not mechianically retarted, but ive only worked on honda mostly, and i'am a little bit nervous about working on my rotary, being that they are a little bit more touchy, to error, so does anyone have maybe a engine diagram i can look at or use while i attempt this?
