My custom Holset Turbo Build (a step away from the norm)

yea, sound slike we need to do some thinking on your car, something isn't right and if i were to take my first guess maybe you have a timing (cam gear) off a tooth.. they can be perfectly aligned and the crank be off by only about the width of the mark on the disk but it's enough to make a difference yet i've seen people post "is this correct" pics and people ok it (i use the trick in the vfaq where you pre-rotate/set the cams ahead - PM me if you need the info or think it might be timing belt related) I say this might be it because of the new engine install, you'll still get great compression readings, and nothing will hit but i've seen in both directions where my one friend had his turbo spooling up so fast (14b only) but still it was uncontrollable coming on at WG pressure and sould spike super high, and myself have suffered incredible lag whenthe crank was off in the other direction.

As for my install, i am super excited, I even felt i had to name the turbo something special snce it's no longer an h1c, nor an hx 35 or 40 really, i've dubber her the H1-3558x (h1c CHRA, hx35 turbine, hx 40 compressor wheel and housing) so i go H1, then 35 for turbine with the 58 being the inducer MM size and the X because it's using some X parts )

but yea you should be seeing faster spool i would think but also from looking at other full on hx40 users in BEP housings the spool is still usually a bit later around the high 4k but usually full on by 5k where you're coming on full on by about 5500RPM but great recovery after shifts and anytim above 5k RPM, which is about how my 67mm turbo was and i think you will find you can outshine those spool numbers either way

I am gone for a day and I miss a lot Can't wait for the sun to come out and dry up all the snow.

If the spool works out for you, I would be interested in one of these machined housings. Of course this is when you have free time but thought I would throw it out there.

I'll update with spool as soon as i can, I'll be searching for dry patches all over town

if it works i will PM you shipping info, I can turn one of these out between other jobs pretty easily, none of what i have coming up requires the mill so centering and setting up a housing to mill won't be an issue at all.
