Hello there,

As the the title implies I have a question about the turbos I'm choosing for my J32a2 civic build next year.

There are two turbos, a 8 blade hx35 and a 7 blade hx40.

The goal is 400whp-450whp ran on stock rods.

Now is the hx35 efficient enough to get me to my goal? Or will it, like many other people online have assumed, choke the engine? According to the compressor maps for these two turbos it would appear that the hx40 is better for my application but is it?

Apparently no one has really done this mod, using a twin scroll turbo, and if they have, they haven't shared the results. Only one person has claimed to run a hx35 on a j35. He said that it had instant power but died up top.

If hx35 don't like low boost, and I'm reading the hx40 compessor map, shouldn't it not like low boost either? But if I'm reading it right, the maximum efficiency is at about 15psi is it not? And should put me at 450whp right?

Sorry for the confusing question. Any responses are appreciated!

 

hx35 is too small run the 40

 

Thanks!
