if the fuel is there, then it's all about moving the air, so yeah intake restrictions, and exhaust backpressure after the turbo... if you have an exhaust at all...

with how late that spools, i'd imagine you probably have a boost leak of some sort, or a wastegate diaphram issue.

that turbo spools faster on a b16

when i first read your post i thought you had a 60-1 turbo. after rereading it it sounds like you just have a .60 compressor housing which is standard on a TON of turbo's.

do you know exaclty which turbo that is?

this is a 60-1 on a b16 on pump gas.



inline pro manifolds will usually pick up some power down low by raising vtec substantially from where you have it.

it was something thrown together by a friend.
its a garrett 60-1 compressor wheel and housing with a .63 precision turbine wheel t4 housing.
where do you suggest raising vtec to?
