Hi All,
I have a civic wagon Rt4wd Turbo I use 76mm cp piston cr10.5 , Turbo Holset Hx35 5500Rpm full boost ,
I think little late come boost I want 4000rpm full boost I think valve size change 1mm big or Turbo change
I need help Thank you

 

lol get a new engine

 

and by that I mean a built b, h, f or k series

 

simple.... get a hy35... same compressor wheel, smaller turbine housing. hx35 too big to spool at 4k with a 1.6L.

also, what size is the turbine housing on your hx35?

 

12cm tribune housing , now I run 1 bar boost 7200 rpm

 

Either find a decent condition hy35 or find a 9cm housing from Tim's turbos so it'll spool up quicker..that's what I did with my baby h1c

 

Before I think evo9 turbo but expensive and flange diffrent
Good idea 9cm housing ,
Maybe come 4000rpm fullboost ?
