Hey there im in need of help, i've googled but dont seem to find the info i need so every help i can get will be appreciated. I have a T4 Full-Race mani. so i will need a T4 turbo, What turbo would be the best for my pwr goals=380-450. Want something that will spool fast, want it for highway & Track.
BUILD
Motor= block=b18c1, Head=b16- might get supertech springs & retainers not sure yet
Turbo=
Turbo mani.= full-race Topmount T4
Intercooler= 750whp rated full-race w/3'' piping
Downpipe 3''-4''
Wastegate= 44mm tial
Bov= 50mm
Injectors= ID 1000
Internals= arp head studs i know
Ecu= s300
Manifold= Victor x

 

a t4 turbine side is straight overkill for your power goals, until you get up into the 600-700 range a t3 turbine will do just fine..


and the words quick spool and t4 do not go together on a honda.... you'll be lucky to see full boost by 7000rpm with even the smallest of t4 turbine sides.

sell your t4 stuff and switch to t3, also if you think you're gonna make 450 on stock internals you're living in a dream world

 

Oh ok well than I guess I'll just build the block. Don't feel like selling stuff too many lowballers, so if I'm looking to push 550-650 should I go T3 or T4?

 

Garrett T3T4 60 trim .63 AR Stg3 will get you in the range and be at full boost by 4000-4500 rpm.

 

At that point, you could use either. I still would have just cut the FULL-RACE OMG flange and put a T3 one on. Many more options that way.
