ok so i have a d1.6y8 board and sleeved bock crowler built head t3 t4 turbo 3in down pipe with 3in thermal ext and a ram horn header pro intake and throtel body all kinds of stuff basicly im not getting very much turbo spool till about 4000 rpms at 15psi with a greedy e.01 boost controller how can i get a faster spool???

 

step down to a smaller size turbo.

 

if i go down in size will i lose top end and i dont really want to go any lower in my boost can i still keep 15 to 18lbs without over heating it ????

 

what kind of gas are you running?

That's a huge turbo for that tiny Honda engine. there are very few ways to get it to spool faster.

 

Either accept the lag for what it is, step down to a smaller turbo, or spend a lot of money and get a variable geometry turbo. Those are pretty much your only options; lag is a trade-off for having a larger turbo.

Most smaller turbos (Like Mitsubishi's 14B) are efficient up until around 25psi; that's when they start spinning too fast for their own good. Keep in mind you'll be making less power at the same amount of boost compared to a larger snail.

 

cool thx every one for lookin out. im runn 91 to 112 octane .ya i knew i would have some lag but first gear i can only get maybe 5psi getting on it what is that due to??? just it being a big *** turbo???
